摘要本文採用熱熵為設計目標函數,在固定熱傳量之下,藉由最小化熱熵,求得微小型高密度氣冷式熱交換器之最佳鰭片數目及其最佳厚度。設計環境為限制熱交換器之總體積,熱效率需大於某定值。由此所設計得到之最佳熱熵下,亦可為最小的總熱阻及最低之鰭片底座溫度。由本研究之結果顯示,最佳設計並非與愈多的鰭片數成正比。本文之解析部分採用PHOENICS 3.3軟體之助,可得熱交換器熱傳之分布,即可得知熱交換器之最低溫度及其所在位置。;The entropy generation is adopted as the objective function, under thefixed heat transfer rate, the number of fins and the thickness of eachfin can be obtained by minimizing the entropy generation for a microhigh-density air-cooling heat sink with rectangular fins. The designenvironment includes the volume restriction and the minimum thermalefficiency of the heat sink. The optimum entropy generation alsogenerate the minimum thermal resistance as well as the minimumtemperature of the fin base. The final result shows that theincreasing number of fins dose not mean a high heat transfer. Theoptimum design in this paper shows that the heat dissipation per unitvolume of the micro high-density heat sink is larger than that of thenormal size heat sink. Thus the high-density micro air cooling heatsink requires to be researched and further developed in the further.The software called PHOENICS has been used for the analysis oftemperature distribution analysis all over the fins. The lowesttemperature and the location along the fins also can be found byPHOENICS.
