Program for Rapid Computation of the Thermal Performance of a Heat Sink with Embedded Heat Pipes
摘要
This article uses Visual Basic commercial software to develop a Windows program for rapidly calculating the thermal performance of a heat sink with embedded heat pipes. A heat sink with embedded heat pipes transfers the total heat capacity from the heat source to the base plate with embedded heat pipes and fins sequentially, and then dissipates the heat flow into the surrounding air. The computing core of this Windows program employs the theoretical thermal resistance analytical approach with iterative convergence, as stated in this article, to obtain a numerical solution. The results show that the estimation error between the numerical and experimental solutions is less than 5%. From this Windows program, the optimum height of the embedded heat pipes inserted through fins is 21mm and 15mm for one pair and two pairs of embedded heat pipes, respectively.
