摘要

現今電力成本及節能意識上升，電力機房除了傳統的冷氣冷卻之外，熱的集中管理也是相當重要，但使用傳統熱管所費不貲，需搭配散熱鰭片等導致且構造極大等等，都並非是最佳解決之道，PHP則對於上述問題的提供一嶄新概念。本實驗目的是為了解400x1400x3mm^3尺寸下之工業用PHP散熱器，在不同填充物質之下的移熱能力而設計之實驗。實驗的結果為R134a最大熱傳量皆為1100W，CO_2則低於660W。如此一來對於未來工業用PHP熱管之設計，散熱鰭片及擺設位置等可以提供更精准的參考資料。

Nowadays, rising of electricity cost and energy-saving awareness, centralized management of heat is more important than traditional air-cooling in Electrical room. Using the traditional heat pipe is not the best solution because of its cost and huge size with heat sink for heat dissipation. Pulsating heat pipe (PHP) provides a new concept for this problem. This study is to understand maximum heat transfer rate of PHP for industrial use under 400x1400x3mm^3 size with different working fluid. Result shows maximum heat transfer rate of R134a is about 1100W and CO_2 is below 660W. With these results, we have a great reference for design of PHP for industrial use in the future.
