本研究以雙相流潛熱變化的特性，討論一種迴路式熱管對於電子熱傳上的助益，實驗方式是以一個外形為 50mm*60mm*6mm 的基部系統與長425mm 的迴路系統及散熱鰭片所組成的迴路式熱管為本體，加熱器作為熱源模擬電腦的中央處理器，利用風扇帶走分散在散熱鰭片上的熱量;實驗方法為量測加熱器溫度與風扇入口溫度以獲得熱阻值，並探討其效能，實驗中改變工作流體的容量以及改變風扇轉速為變數，以探討各種變數對於性能的影響，用來作為未來性能改良的參考;分析實驗結果發現，工作流體在理論值時有最大熱傳量以及最佳熱阻性能，而冷卻段的散熱效果優劣也影響熱阻性能。

　　The experimental study is to discuss the characteristic of a looped heat pipe on electronics cooling, utilizing the working fluid latent heat property in a two-phase flow environment. This looped heat pipe is composed of a 50*60*6mm base system, a 425mm looped pipe and an array of cooling fins. A dummy heater is used to simulate a CPU heat source and the heat distributed on the cooling fins is moved by a blower. The way of thermal resistance estimation is to measure the heater temperature and the blower inlet temperature. The variations of working fluid volume and the rotational speed of blower on the thermal performance are discussed. It is found that theoretical working fluid volume has the maximum heat flux and the lowest thermal resistance. Moreover, the heat dissipation capability at the cooling fins also affects the overall thermal performance.
