本研究的目的在於利用銅質流道建立一套完整的微流道散熱測試與實驗系統，並挑選出擁有低沸點、潛熱值佳與環境傷害小的冷媒HFE-7100為工作流體進行沸騰熱傳實驗。研究內容分別探討在相近水力直徑之下，改變質量通率(G=39、55、78、90、180 kg/m2s)、深寬比(AR=0.83、0.99、1.65、2.47、4.23、6.06)與漸擴設計(等截面積與漸擴角度1°)對於沸騰曲線、熱傳遞係數與臨界熱通率的影響。
在等截面積與漸擴角度1°的銅質微流道在相近水力直徑下進行沸騰熱傳的研究結果顯示，漸擴角度1°之微流道比等截面積流道擁有較高的雙相流穩定度及較高的移熱能力。在單相強制對流區與雙相沸騰區內，壁面熱通率、底面熱通率與熱傳遞係數皆會隨質量通率增加而提升；臨界熱通率則會與質量通率近似於一正比關係。
深寬比的效應對漸擴角度1°的研究結果顯示，深寬比的改變對微流道內的沸騰熱傳具有顯著的影響。在相近的水力直徑與質量通率下、底面臨界熱通率主要受到熱傳面積大小變化的影響，隨著深寬比增加而大幅度提高；壁面臨界熱通率主要受到角落液膜厚度的影響，在深寬比為0.99時有一最大值。
比對成果發現，在相同的水力直徑與質量通率下，漸擴微流道與高深寬比微流道擁有較高的系統散熱能力。本實驗系統利用冷媒HFE-7100於銅質微流道之最高底面臨界熱通率為1136kW/m2，亦即每平方公分可帶走113.6瓦的熱量。
