Thermal Shock Test Chamber FAQ Guide

All your questions about the thermal shock test chamber are answered in today’s guide. Whether you want to learn about definitions, benefits, features, or applications, you’ll find everything here. Read on to learn more.

First, thermal shock test chambers are essential for testing tools in the metal, plastic, rubber, electronics, and other material industries. They are used to expose composite materials or material structures to extremely high and low temperatures in the shortest possible time, allowing them to be tested in real time.

Therefore, this allows them to be tested in the shortest possible time. Because changes in chemical composition or physical damage can cause thermal expansion and contraction. The thermal shock test chamber shall comply with the following test procedures: GB/T2423.1.2, GB/T10592-2008, and GJB150.3 high and low-temperature impact test.

In addition, the electrochemical change caused by the cracking or fracture of the finished product is one of the effects of the thermal shock test. For example, some metallic materials, such as the body-centered cubic lattice of low-strength steel, decrease with the use temperature. Due to the rapid reduction of plasticity and toughness, material embrittlement occurs.

Linkotest designs and manufactures environment test chambers including temperature humidity chambers, walk-in test chambers, thermal shock test chambers, fast change rate test chamber, agree chambers, xenon arc test chambers, uv test chambers, accelerated aging test chambers, rain & spray test chamber, salt spray test chamber, compound salt spray test chamber, laboratory oven, and other products to meet your different environmental test needs.

Thermal Shock Test Chamber

However, during the final manufacturing process, components and sub-components are developed and designed taking into account the operating environmental conditions. Without this critical step in the manufacturing process, some parts are more likely to fail prematurely.

For example, exposing lithium-ion batteries to extreme cold reduces their life and storage capacity. By testing components, you can ensure their quality and reliability. Most importantly, ensure their overall performance in the intended working environment. Frankly, that’s what happened.

1) Other fields of application

In addition, it is also suitable for electronic and electrical components, automation technology components, communication components, automotive supplies, metal materials, chemical materials, plastics, and other thermal shock test chambers.

Physical conversion of BGA, PCB substrate triggers, semiconductor materials, electronic chip ics, ceramic magnetic and functional materials to test the sustained tensile strength of their raw materials against high and ultra-low temperatures, as well as the chemical reactions or physical damage of cold and thermal shrinkage, can be made from heavy machinery components that require their ideal testing tools for highly accurate mass determination.

You can use the thermal shock test chamber as a tool to perform thermal shock tests at different stages of product development and with different objectives.

  1. Can be used to identify flaws in the product design and manufacturing process during the engineering development stage.
  2. Used as a foundation for decisions on batch production stage acceptability and product finalization or design appraisal.
  3. To prevent early product failures, a screening technique for environmental stressors is used.

Thermal Shock Test Chamber

Compared with other shock testing machines, a thermal shock test machine has unique characteristics. These include:

  • Horizontal air circulation
  • Open air, fast reactive, low quality, nickel-chrome wire heating element
  • Two zone types with hot/cold compartment settings
  • Cascade refrigeration system, TEV control, and two semi-hermetically sealed compressors
  • Airtight, 100% continuously welded stainless steel for the inner tank
  • Fully automatic, PID-controlled, alphanumeric display
  • Vertical configuration
  • Ceramic insulator
  • Fiberglass and polyurethane insulation ensures minimal heat transfer
  • Double gasket doors provide additional insulation

  • The double-carrier transport system is made of stainless steel, wire mesh basket
  • Adjustable recirculating air louvers for optimal performance
  • Conveyor capacity 200 pounds
  • Temperature protection system for each zone (hot and cold).

Even for thermal shock test chambers, there are different types. This can meet your different requirements. Here, we’d like to introduce you to the three most common types.

  • First, a vertically oriented thermal shock chamber with two independently controlled hot and cold zones. One on top of the other. In addition, individual product carriers move between each region, causing the temperature of the product to change dramatically. One advantage of the vertical orientation room is that it takes up less floor space, making it suitable for small laboratories.
  • Second, The horizontally oriented thermal shock chamber has three adjacent independent areas. Including hot zone, environmental zone, and cold zone. The added environmental area allows for three-zone testing, which is required by some military standards. In fact, this unique and versatile cavity configuration can also be used for two-zone testing. This is achieved by programming the product carrier as it automatically transfers the product from hot to cold and back again. Thus removing the surrounding area of inhabitants.
  • Third, the cold zone of the dual-task thermal shock chamber is located between the two hot zones and is vertically arranged up and down. The product you are testing is placed in one of two product carriers and transferred between areas that generate severe thermal stress. In this case, at least one product carrier often occupies the cold area. This design makes efficient use of the chamber cooling system and provides a higher product test throughput than standard thermal shock designs. We install heaters in the cold zone for defrosting, allowing the area to operate as a temperature cycle chamber when not being used for thermal shock testing.

Thermal Shock Test Chamber

What you need to know is that the thermal shock test chamber uses an integrated construction. That is a text box, refrigeration system, heating system, blower motor, and electrical control cabinet as one. What’s more, the electrical control part is placed on the side of the test chamber for easy operation. Here are some details about the thermal shock test chamber for your reference.

  • There is a cable hole on the side of the test chamber studio, the size is ф50mm; To prevent the signal line from slipping and falling into the test hole, place the silicone plug in the test hole.
  • Sample chamber size: 300*400*400mm(W*D*H);
  • The test chamber shell is made of iron plate sprayed plastic, and the inner shell is made of 304 stainless steel plate;
  • The insulation material is made of polyurethane foam, the thickness is 100mm, the thermal insulation effect is good, and the outdoor surface of the test does not form frost or condensation;
  • The cabinet is equipped with a condensing drainage device.
  • The equipment is a single door, and each door is sealed with silicone rubber sealing strips; a Double door can be customized.
  • The door of the test chamber is equipped with a viewing window and a lighting device (cold light source);
  • The thermal shock chamber heating system includes a continuous PID regulation, using SSR solid state relay as a heating actuator, safe and reliable, with a separate over-temperature protection system.
  • In order to ensure a high uniformity index, the thermal shock test chamber is equipped with an internal circulating air supply system.

While the industry and use of a hot cell are almost unlimited, it is important to define several key parameters when sourcing a hot cell for your testing needs.

1) Performance

In order to ensure the correct hot chamber, it is crucial to define the key performance parameters. Includes the desired temperature range, temperature, and desired rate of change for the product, as well as a complete test overview.

Does your test include humidity and temperature? If so, how will this affect your product and test specifications? How often do you check? Knowing the duration and frequency of the thermal test will help to better determine the parameters of the desired hot chamber.

2) Size

Usually, knowing the dimensions, material composition, fixture requirements, and total mass to be tested will help determine the size of the hot chamber to meet your requirements. In fact, benchtop and REACH-IN hot chambers are designed to maximize laboratory space and efficiency.

You use the standard performance of a large room but with a small footprint. Larger test equipment (DUT) may need to be loaded via a trolley, pallet jack, or forklift, which usually requires a walk-in room to meet your specifications. Understanding the footprint, utilities, and infrastructure of a lab or facility is critical to ensuring that the right system is selected and installed.

3) Timeline

Once you’ve defined your performance and scale requirements, you’ll want to understand the timeline and budget considerations that could affect your test plan. Most of the accessible and smaller hot rooms are available from different manufacturers in shorter lead times, sometimes even in stock and ready for shipping.

As a result, these cabins are more economical than comparable walk-in and drive-thru-es. Lead times vary across the industry, but a common principle is to give yourself a year to plan, search, buy, receive, install, and verify a walk-in or driver-free hot room.

Thermal Shock Test Chamber

We understand that thermal shock test chambers (or temperature test chambers) are widely used in a variety of industries and applications. Typical applications include steady-state or stability testing, thermal cycling, or thermal shock. Key industries need to define specific testing protocols and standards that need to be updated frequently.

This is a way to keep up with the rapidly accelerating pace of consumer technology. Furthermore, the thermal shock test chamber is suitable for aerospace, electronic instruments, materials, electricians, automotive metals, electronic products, various electronic components, wires, cables, etc.

Thermal shock testing simulates the extreme temperature changes that a product may be exposed to in your hands during actual use. For example, when people move into a warm home on a cold winter day, think about the vibrations experienced by smartphone batteries.

On the other hand, aircraft components have to withstand temperature contrasts. Leaving an airport runway in 95-degree weather and encountering -40 degrees to -70 degrees at its peak.

Several key industries and applications include:

1) Electric vehicle batteries

As the demand for vehicle electrification continues to grow. OEMs, suppliers, and manufacturers must keep up with the changing technology and regulatory environment. While a variety of methods and specifications exist, some key EV battery test applications include thermal cycling and thermal shock, reliability and robustness against vibration, overcharge and discharge protection, and overtemperature protection.

The hot chamber is particularly suitable for simulating cold start conditions where a variety of extreme temperatures need to be verified. In general, several common standards for automotive battery certification include UL 1642(lithium battery), IEC 62660, ISO 12405, SAE J1772, and IEEE 1725.

2) Aerospace and Defense

According to the survey, various space and defense programs rely on ground testing to ensure the correct and successful operation of components, systems, payloads, sensors, and more. The hot chamber allows the components to undergo thermal cycling to simulate the harsh environment at high altitudes.

However, thermal vacuum chambers allow space components and subsystems to withstand extreme temperatures and deep vacuums. The commercial, military, and aerospace industries require industry standards for precise thermal resistance definitions, including MIL-STD-1540, MIL-STD-750, EIA-364-32, and others.

3) Electronics

Thermal testing and cycling of electronic components typically detect defects by exposing parts to temperatures higher than normal operating temperatures. This includes solder joint and seal failures, as well as lead and mark damage. Thermal stress on electronics and components can also help identify changes in the physical properties of components that can reduce the reliability and longevity of these products.

In other cases, thermal testing is used for component validation where the temperature range exceeds the normal operating range and is used to determine the maximum and minimum operating temperatures for these components. A wide variety of industry standards exist, although the widely accepted 11 standards include JDEC 51, which is specifically designed for the thermal measurement of component packages under a variety of environmental conditions.

4) Other Industries

It has a wide range of industries and services, and the products developed must meet national and international standards and be used in the form of thermal testing. Some industries and standardization organizations include construction and building materials (ASTM, ANSI, ISO), chemicals, energy commodities, consumer goods, and healthcare, including pharmaceuticals and medical devices.

Thermal Shock Test Chamber

Since the operation of a thermal shock test chamber involves high and low temperatures, there are several cases that you should be aware of.

  • Test or store samples of flammable, explosive, volatile substances or samples of stored corrosive substances should be avoided
  • Inspection or storage of biological samples is not allowed
  • Detection, storage of strong electromagnetic radiation source sample detection, storage of radioactive material sample detection, storage of highly toxic substance samples
  • Detection or storage of samples that may produce flammable, explosive, volatile, highly toxic, corrosive, and radioactive substances during testing or storage

1. The thermal shock test chamber is available in two and three-zone configurations. Two-zone chambers use the movement of the basket to test how the product is affected by temperature, while three-zone chambers use the “temperature storage region” to introduce a temperature shock into the test area.
2. The choice of temperature: The thermal shock test chamber’s typical temperature range is -70°C to 150°C; temperatures below -70°C or over 150°C require customization.
3. The option of the test space: the basic test space capacities are 50L, 80L, 105L, 150L, 225L, etc., but they can also be modified depending on the size of the product.

4. There are two cooling options: air cooling and water cooling. While water cooling has no test-environment requirements, it is more difficult to carry and takes up more room than air cooling. Air cooling saves space, but the test environment must include air conditioning to help disperse heat from the equipment.
5. Temperature and humidity variations: the rate of change in the working space’s center characteristics over time in a stable cold and thermal shock test chamber.
6. Equipment in a stable state, the work area at a specific time between the test points of the difference, and homogeneity of temperature and humidity

Thermal Shock Test Chamber

If you want your testing machine to extend its lifespan, you need to take efforts to maintain it and take good care of it. Here are several aspects and steps you can follow while taking care of your thermal shock test chamber.

1) Test chamber position

It cannot be installed upside down. The instrument must be placed horizontally on the floor so that the door to the thermal shock test can be easily opened and the noise during mechanical action is reduced.

2) Environmental test chamber

We also need to maintain a well-ventilated space, so that the condenser can play the role of heat dissipation. You need to keep the instrument in a cool place. If the instrument is not exposed to sunlight, do not go near the stove and other heating elements. So as not to affect the freezing effect of the instrument.

When you open, close, or remove the test object in the furnace. Do not let the object touch the bonding side of the furnace door, so as not to damage the bonding side and shorten its service life. In addition, the ground around and at the bottom of the fuselage should always be kept clean to avoid accidents and performance degradation due to a large amount of dust inhalation of the unit.

Do not adjust the set points of the two overtemperature protectors in the distribution box. Adjusted before delivery, the protection switch is used to protect the heating tube and humidifier tube to prevent air combustion and water shortage alarm. Thermal shock test chamber set point = temperature set point + 20℃~ 30℃.

Tap water inspection and maintenance, water pipe, easy plugging device. Please be sure to check regularly whether there is water leakage, or a plugging phenomenon, if so, please exclude or notify the company in time.

3) Test chamber voltage

Use a dedicated switch for power switches. Do not use the power cord of the plug with other motors.

Do not place it on the floor or in a damp place to avoid stepping on or leaking electricity. The transformer should be provided at a lower supply voltage, raising the voltage to the rated value. Do not burn out the compressor motor due to low voltage. When the instrument is tested, the operating door should not be opened for a long time to avoid water droplets in the temperature control room.

4) Test chamber protection cleaning

You should always keep it clean. When the external test chamber is cleaned, apply some varnish and wipe with a soft dry cloth. If it is too dirty, wash it with neutral detergent and water. Do not use brushes, powder, acid, benzene, or hot water. Wipe the inside and outside of the machine, the back or the wall is easy to accumulate dust, and pay attention to the heat dissipation of the condenser.

If the model is water-cooled, pay special attention to the treatment of water quality. The use of groundwater should be avoided as much as possible. Because the groundwater contains more minerals, it is easy to cause the scale of the instrument, affecting the cooling effect of the instrument, which will reduce the service life of the humidity and temperature control room.

In fact, the high current contacts in the distribution room and the distribution room should be cleaned and serviced at least once a year. Loose contact will put the entire equipment in dangerous working conditions. When cleaning, please use a vacuum cleaner to remove indoor dust.

#1. Some considerations

Please remember that the electrical room should be cleaned at least once a year. And use a vacuum cleaner to remove indoor dust. The exterior of the hot and cold shock chamber should be cleaned once a year or more and cleaned with soapy water.

The most important thing is that the radiator (condenser) of the refrigeration unit should be regularly maintained and kept clean. Because the condenser’s sticky dust will cause the compressor’s high-pressure switch to jump and a false alarm. In addition, the condenser of the hot and cold shock chamber should be regularly maintained every month. After powering on the condenser, use a vacuum cleaner to remove the dust attached to the condenser heat network. Or blow it away with a stiff brush or high-pressure nozzle.

When the test time arrives, you must take the test item in the off-state. And the staff must wear dry, electric, heat-resistant gloves. What’s more, internal impurities should be removed before the equipment is run.

The above is the maintenance method of thermal shock test equipment. I hope you will adopt it. The equipment also requires meticulous maintenance. Perform careful maintenance of the instrument. Not only can avoid the operator’s injury but also can make the instrument long-term use.
