Thermal Performance Test System for Micro Flat Heat Pipe
摘要
Abstract
For accurately evaluating the thermal performance of micro flat heat pipe (MFHP),a ther-mal performance test system was constructed,which consists of heating/cooling systems,the test sec-tion,signal measurement module,visual system and the data processing and logging section.The test experiment was achieved in the vacuum environment to guarantee that the input heat can mostly be transferred by MPHP.Input heat flux and temperature at different positions of MFHP were measured, and then two thermal parameters of thermal resistance and effective thermal conductivity could be ob-tained.The thermal performances of both MFHPs with working fluid and without working fluid were investigated in the test experiment.The results show that the thermal conductivity of MFHP with working fluid is three times as much as that of MFHP without working fluid when input power is 2W, while the thermal resistance is 3.5 times lower.Therefore,the thermal performance test experiment system in this paper can be used to evaluate the MFHP effectively.关键词
