FAQ
What is a thermal shock tester used for?
In fact, as a tool, the purpose of the thermal shock tester is different when applied to different stages of product development:
- In the product development phase, it is used to identify problems in product design and processes;
- Product finalisation or design identification and batch production stage acceptance decision-making to provide a basis;
- In order to troubleshoot early product failures, environmental stress screening is applied.
What are the advantages of the cold and hot shock test chamber?
- Reliability: The cold and hot shock test chamber can simulate extreme environmental conditions and conduct all-round testing of products, thus ensuring their reliability and weather resistance.
- High efficiency: the thermal shock chamber can test multiple samples at the same time, greatly improving the testing efficiency.
- Repeatability: The cold and thermal shock test chamber can be set up through the programme to carry out repetitive tests to ensure the consistency of product performance.
- Flexibility: The cold and thermal shock test chamber can be customised and modified according to different testing needs to meet a variety of different testing requirements.
- Energy-saving and environmental protection: the cold and thermal shock test chamber adopts advanced energy-saving technology, which can minimise energy consumption, while using environmentally friendly refrigerants to reduce the impact on the environment.
Why is Cold and Thermal Shock Testing necessary?
Cold and thermal shock testing simulates the use of a product under extreme temperature conditions and assesses the reliability and durability of the product. Through this test, performance problems that may occur during temperature changes can be identified and solved, improving the quality and reliability of the product.
How are the time and temperature ranges for thermal shock testing determined?
The test duration and temperature range should be determined based on product design requirements, industry standards and customer needs. Typically, the test time can be set from a few hours to a few days, and the temperature range can be determined based on the extreme temperatures of the product’s environment.
What are the main application areas of thermal shock tester?
- Electronic product testing: Cold and thermal shock test chamber for electronic products, hardware, circuitry and other tests to verify its reliability and durability under different temperature change conditions. This is essential to ensure that electronic products work properly in a variety of harsh environments.
- Automotive vehicle and parts testing: thermal shock test chamber can test the engine, transmission, battery and other automotive parts. These tests are done to ensure that the car will still function properly in extreme environmental conditions of heat or cold.In order to assess the reliability of a vehicle under extreme climatic conditions, complete vehicle test trials can be carried out.
- Product Performance Evaluation: Thermal shock chamber can evaluate product performance, such as breaking strength, coefficient of thermal expansion, durability, and other properties, which are useful to ensure that a product will not break or be damaged in extreme environments, which is important for improving product design and selection.
- Testing of optoelectronic devices: In order to determine the performance stability and power output of optoelectronic devices under extreme temperature conditions, optoelectronic devices such as LED lamps and solar panels can be tested in thermal shock test chambers. This is very important for the application and development of optoelectronic devices.
What do I need to pay attention to the operation of the thermal shock test chamber?
- Try to avoid turning off and on the refrigeration unit within three minutes to avoid affecting the function of the compressor.
- The tester cannot test or heat flammable, explosive and strongly corrosive substances. Failure to do so will result in accidents or damage to the machine.
- In the test chamber samples can not be put too much, too much sample will lead to air circulation in the test chamber, thus the performance of the test chamber.
- When using the door should be closed, closed tightly, otherwise the temperature leakage, not up to the performance of the region.
- Designated personnel to operate the machine, so as not to cause early damage to the machine.
- When the door is opened during the test, icing occurs on the interior evaporator and other sealed areas. As the temperature gets lower, the icing will get worse. If the door must be opened, open and close it as soon as possible.
- When the operation is finished, wait until the machine stops completely before opening the door to get the test product.
- During operation, do not open the door unless absolutely necessary, otherwise it may lead to the following adverse consequences.
High temperature gas rushing out of the chamber …………… is very dangerous!
The inside of the door remains at a high or low temperature ……… causes accidents!
Excessive temperatures may trigger the fire alarm and cause false action!
Opening the door: To prevent large amounts of hot air from entering the interior of the chamber and causing injury to personnel. When the operator opens the door, he must move backward in the direction of the opening. - To avoid electrostatic induction, the test chamber must be grounded!
- Circuit breaker, temperature over-temperature protector, to provide the machine test products and the operator’s safety protection, so please check regularly.
- During operation, please do not touch the inspection, in order to avoid electric shock or injury to the fan, and the danger, so please stop the operation first, turn off the power before repair.
- Non-functional personnel may not carry out maintenance and inspection of the machine, maintenance and inspection, carried out by a full-time staff, and at the same time, there should be a guardian to monitor the prevention of uninformed personnel to power on and off, resulting in electrocution injuries.
