ABSTRACT A comprehensive study for testing of cylindrical heat pipe has been carried out with a number of experiments. Characteristics and performance of heat pipe were evaluated individually with water, methanol, and acetone at different inclination angles (θ). Results obtained show that heat pipe charged with acetone has the smallest thermal resistance and highest heat transfer coefficient compared to other working fluids, hence identified as the best working fluid for the prepared heat pipes. Also, the best angle of inclination for the working heat pipe is 45° as the thermal performance of the heat pipe is optimal at this angle.

热管实验探究：不同流体的性能评价

摘要 通过大量实验，对圆柱形热管的测试进行了全面的研究。分别用水、甲醇和丙酮在不同的倾角 (θ) 下评估热管的特性和性能。所得结果表明，与其他工质相比，填充有丙酮的热管具有最小的热阻和最高的传热系数，因此被认为是制备的热管的最佳工质。此外，工作热管的最佳倾斜角度为 45°，因为该角度热管的热性能最佳。
