摘要

本篇論文主要目的爲設計一組小型毛細式泵吸環路（其尺寸爲4.2(上標 *)3.8(上標 *)0.8平方公分），並應用於高階CPU晶片上冷卻，經由實驗結果得知以下的熱流特性一、環路在相對高度（蒸發器與冷凝器位置差）7.5公分下可移熟40W並將控制電子元件表面溫度低於100℃，二、環路可以在相對高度在1cm（接近水平位置下）不需的外力下便可藉由自然循環的方式從蒸發器移熱一段距離至冷凝器，三、經由透明環路設計了解工作流體在環路內輸送現象，四、最佳填充量和環路熱阻關係。

The paper is to design the capillary pumped loop which dimension is 4.2(superscript *) 3.8(superscript *) 0.8 cm^3 for cooling of high end electronic components chips (such as CPU). The heat transport characteristics of capillary pumped loops are obtained from experimental results. The results shown that: (1) the loop could dissipate heat 40W and keep the surface temperature of chip under 100℃ under relative height 7.5 cm; (2) the loop could transfer heat for a distance from evaporator to condenser separated by natural circulation without any external driving forces if the relative height (evaporator and condenser position) higher than 1 cm; (3) through the semi-transparent loop design, some transport phenomena of the working fluid could be observed; (4) the relation between optimal inventory with thermal resistance of the loop.
