Program for Rapid Computation of the Thermal Performance of a Heat Sink with Embedded Heat Pipes

Abstract

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.這篇文章使用Visual Basic商業軟體開發一可迅速計算嵌入式熱管熱沉熱性能績效評估的視窗程式。嵌入式熱管熱沉從熱源將熱量轉移到嵌入式熱管熱沉的基座平板和鰭片，然後消散熱流到周圍的空氣中。這個視窗程式的計算核心是使用疊代收斂結合理論熱阻分析方法評估，如本文所述，可獲得其數值解。由本文結果可知，在視窗程式計算後所得到的數值解和實驗值之間，誤差估計在5%以內。又從此視窗程式的計算結果，嵌入式熱管的最佳嵌入於鰭片的高度，兩根嵌入式熱管熱沉為21mm、四根嵌入式熱管熱沉為15mm。
