Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of phase change radiator detection, in particular to an airtightness detection tooling for a phase change radiator. Background Technique
[0002] A phase change radiator is a new type of heat dissipation device, which is mainly applied to the heat dissipation treatment of high-power electronic devices such as computers and mobile devices. The working principle of the phase change radiator is to take away the heat generated by the device by the heat released or absorbed during the phase change process when the phase change material is heated to its phase change temperature. Airtightness refers to whether the phase change radiator can effectively prevent air and other gases from entering the microchannels under normal working conditions to ensure the effective heat transfer of the phase change material. Therefore, the detection of the airtightness of the phase change radiator is very important.
[0003] However, in the current prior art, a differential pressure valve is generally used to detect the airtightness of the phase change radiator. However, due to the diffusion characteristics of the gas, it will diffuse from the gaps of the radiator. However, since the air leakage amount is relatively small and will not affect the measured value of the pressure difference, it is difficult to detect. However, in the actual application process, it will still have a relative impact on the performance of the radiator. Summary of the Utility Model
