Heat pipe cold plate is a commonly used thermal management device, which may undergo physical and chemical changes under different environmental conditions, thereby affecting its performance and lifespan. In practical applications, the heat pipe cold plate may need to withstand the influence of extreme environments such as high temperature and low temperature. For example, in the fields of heat dissipation of electronic equipment and thermal management of spacecraft, it needs to be used in extreme temperature environments. Therefore, in order to ensure that the heat pipe cold plate can maintain its heat transfer performance and life in different environments, it is necessary to conduct high-low temperature resistance tests to evaluate its thermal conductivity, heat transfer coefficient, evaporation and condensation performance at different temperatures, etc. And then guarantee its reliability and stability in practical application.
The high-low Temperature Test Chamber is a kind of equipment specially used to simulate extreme temperature environment, which can test the durability and stability of various materials and products under high-low temperature environment.
experiment procedure
Place the heat pipe cold plate in the high-low Temperature Test Chamber, and make sure there are no other objects around it.
Set the temperature range and change rate of the high-low Temperature Test Chamber, generally according to the standard test requirements.
Open the high-low Temperature Test Chamber and start the high-low temperature cycle test.
In high temperature and low temperature environments, the heat pipe and cold plate are continuously tested. The general test time ranges from several hours to several days, and the specific time is determined according to the test requirements.
According to the test requirements, gradually increase or decrease the temperature in the high-low Temperature Test Chamber, and record the performance and life data of the cold plate of the heat pipe at each temperature point.
After the test, analyze and evaluate the test data to judge whether the heat pipe cold plate meets the design requirements.
