Gravity Effect on the Thermal Performance of Flat Plate Heat Pipe (FPHP)

重力效應對板式熱管性能之影響探討

摘要


本文針對「具毛細結構」及「無毛細結構」板式熱管於不同傾斜角下進行實驗測試。藉由不同操作角度,可獲得重力效應對於板式熱管之影響。實驗結果發現,在操作傾斜角-5°~+53°的範圍裡,板式熱管最大熱傳量會隨著傾斜角增加而變大。此外,我們在「無毛細結構」板式熱管觀察到溫度突降之現象,可定義此區域為沸騰起始區;對於「具毛細結構」板式熱管,根據其不同的熱流現象,我們亦將其熱阻曲線分為三種區域。

This paper presents an experimental investigation of wickless and wick flat plate heat pipes (FPHPs) under different inclined angles. From different operating angles, the gravity effect on FPHP can be obtained. Experimental results showed that the maximum heat transfer rate of FPHPs becomes larger with the increasing of inclined angles (-5°~+53°). Additionally, temperature excursion phenomenon is observed on wickless FPHP; this can be defined as the boiling incipience zone. For wick FPHP, we classify the thermal resistance curves into three zones according to their different thermal behaviors.
