The heat pipe's thermal resistance, which affects its heat transfer efficiency, is determined during manufacturing according to powder type, thickness of the sintered wick, and filling rate of the working fluid. Heat transfer efficiency was then tested at various inclination angles (0掳, 45掳, 90掳) to evaluate the performance of heat pipes. Regardless of the filling amount and test angle, the 200渭m copper powder type exhibited superior heat transfer efficiency compared to the 100渭m type. After analyzing heat transfer performance at various filling rates between 20% and 50%, it was determined that the heat pipe's optimal heat transfer capability occurred at a working fluid filling rate of 30%. The width of the wick was directly related to the heat transfer performance. <iframe src="https://publications.waset.org/abstracts/183110.pdf" style="width:100%; height:400px;"
