This is a study on the enhancement of the thermal performance of a thermosyphon heat pipe (THP) using the ${\mathrm{Al}}_2{\mathrm{O}}_3$ nanoparticle in a mixture of water and Triton X-100 (TX-100) surfactant. The effects of nanoparticle concentration, surfactant concentration, input power, inclination angle, and filling ratio on the thermal efficiency of THP is evaluated experimentally. Experiments were designed by the Taguchi method using Minitab software. According to the results, utilizing a nanofluid/surfactant mixture decreases the evaporator’s temperature, which decreases the thermal resistance and increases the thermal efficiency of THP. The maximum enhancement of thermal efficiency was observed to be 17.7%, and the maximum decrease in thermal resistance was 42.5% using the optimum concentration of nanofluid and TX-100 compared to water. The maximum thermal efficiency predicted by the Taguchi method was 0.8877, which was in good agreement with the experimental value of 0.917.

这项研究旨在通过使用热电偶来增强热虹吸热管（THP）的热性能。 ${铝}_{\mathrm{2个}}{\mathrm{Ø}}_3$水和Triton X-100（TX-100）表面活性剂的混合物中形成纳米颗粒。实验评估了纳米颗粒浓度，表面活性剂浓度，输入功率，倾角和填充率对THP热效率的影响。使用Minitab软件通过Taguchi方法设计实验。根据结果​​，利用纳米流体/表面活性剂混合物降低了蒸发器的温度，从而降低了热阻并提高了THP的热效率。与水相比，使用最佳浓度的纳米流体和TX-100，观察到热效率的最大提高为17.7％，而热阻的最大降低为42.5％。Taguchi方法预测的最大热效率为0.8877，与实验值0吻合良好。
