摘要

摘要热管结合了相变和导热原理，在两个固体表面之间有效地传递热量。研究了圆柱热管的热特性以及影响其性能的各种因素。不同的工质(水、乙醇和甲醇)，不同的芯材(铜和不锈钢)，以及不同的倾角(0°~ 90°)的影响。填充量也在20% ~ 40%之间变化，以分析热管的热阻和有效导热系数。在工作流体填充量为30%的情况下，无论芯芯材料如何，最佳倾角值均为60°。

Experimental investigation of thermal characteristics of a cylindrical heat pipe under varied system parameters and operating conditions

Abstract A heat pipe transfers heat effectively between two solid surfaces by incorporating the principles of the transition of phase and thermal conductivity. The study aims to investigate the thermal characteristics of a cylindrical heat pipe and the various factors affecting its performance. The effect of different working fluids, i.e., water, ethanol, and methanol, wick material, i.e., copper and stainless steel, and angle of inclination varied from varied between 0° and 90°. The fill volume is also varied from 20 to 40% to analyze the thermal resistance and effective thermal conductivity of the heat pipe. The optimum value of angle of inclination is found to be 60° at 30% fill volume of working fluid irrespective of the wick material.
