免除了內部之毛細結構之特點，近年來學者紛紛投入脈衝式熱管之研究，同時也改進了水平式脈衝式熱管之水平啟動之問題，開啟了此被動式散熱元件廣闊的開發潛力。本論文利用CNC機械製程加工封閉迴路水道來做為新型解凍板之開發。將其下鋁板流道加工成突縮突擴管使其增加其震盪能力。本實驗過程先使用體積較小之之實驗型解凍板(Test PHP Plate)，經由實驗型解凍板找出最佳之填充率後，再製作體積較大之標準型解凍板(Model Large PHP Plate)與市面上之高效能解凍板(High Efficency plate)做比較。經由實驗型解凍板之重複測試可以找到當達到最高之溶解速率時，填充率約在75%。與市面上之高效能解凍板做比較可以發現脈衝式熱管解凍板之融解速度為0.0818g/s，高於高效能之解凍板之0.04413g/s。 利用熱擴散測試機台量得一般具氧化層之鋁T6-6061之熱擴散率為α=0.98cm2/s，而量測75%填充率之標準型解凍板可以達到αx=2.200749 cm2/s，高於一般鋁之熱擴散率。

The advantage of avoiding using wick structure inside the heat pipe, researchers start to study and burrow inside a new technology of pulsating heat pipe. While improving the startup problem of horizontal pulsating heat pipe, this new passive component brings up a great potential and a wide range of heat transfer study. In this paper, using Computer Numerical Control(CNC) machine to process a closed water loop system with throat and nozzle design to increase the oscillating ability inside the water loop. First design a small size test PHP plate(200×150×7) , find the appropriate filling ratio due to the result of ice cube melting speed, then design a Model Large PHP Plate(320×200×7) to compare the ice cube melting speed with commercial made High Efficiency Plate. Through experiment the ice cube melting speed of Model Large PHP Plate is 0.0818g/s, faster than Commercial Made High Efficiency Plate, which is 0.04413g/s. By testing the thermal diffusivity of Model Large PHP Plate, the thermal diffusivity is αx=2.200749 cm2/s in it’s actuation direction, higher than the same material of Aluminum which is α=0.98cm2/s. .
