On the Thermal Performance of the Vapor Chamber with Micro-channel for Unmixed Air Flow Cooling
Keywords:Thermal performance, vapor chamber, micro-channels.
Numerical and experimental results on the thermal performance of vapor chamber with and without micro-channel under constant heat flux are presented. The mathematical model of the vapor chamber is a two-phase closed chamber with wick sheet and a wick column. A finite volume method with structured uniform grid method system is applied to solve the model. Effects of micro-channel on the temperature distribution of the vapor chamber are considered. The results obtained from the model are verified with those from the measured data. The experimental tests are carried out and good agreement is obtained with the numerical results. These numerical results are useful for the design to improvement thermal performance of the vapor chamber and also diminished the expense and time of the real test.
