熱管在現代熱管理技術中的應用日益廣泛，其高效的熱傳導性能使其在各個領域中發揮重要作用。熱管通過相變化過程和毛細作用迅速傳遞熱量，已成為電子設備散熱和能源管理的關鍵技術。本文希望將熱管應用於於人體散熱。特別是在可穿戴裝置利用熱管有效帶走熱的特性將人體產生的熱量帶走，從而維持皮膚表面的舒適溫度。本文使用壓克力作為熱管材料再將其結合在運動頭帶上。壓克力材料的使用不僅滿足了結構輕便和易於加工的需求，壓克力的透明性在測試時可觀察管內工作流體相變化的過程驗證其有效性。本文共以11支熱管進行實測並以加熱片做為模擬人體溫度的對象，PMMA熱管在最終帶走相當於0.23~0.28 W功率的熱量(約3.3~3.4 ℃)，相當於加熱片25%的效率。

Heat pipes are increasingly used in modern thermal management technology, and their efficient heat conduction properties make them play an important role in various fields. Heat pipes rapidly transfer heat through phase change processes and capillary action, and have become a key technology for the heat dissipation and energy management of electronic equipment. This article aims to apply heat pipes to human body heat dissipation, especially in wearable devices. Heat pipes can effectively take away the heat generated by the human body, thereby maintaining a comfortable temperature on the skin surface. This study uses acrylic as the heat pipe material and then combines it with a sports headband. The use of acrylic materials not only meets the needs of a lightweight structure and easy processing, but the transparency of acrylic allows the phase change process of the working fluid in the tube to be observed during testing to verify its effectiveness. In this study, a total of 11 heat pipes were used for actual measurement, and a heating plate was used to simulate human body temperature. The PMMA heat pipe ultimately dissipated heat equivalent to 0.23~0.28 W (approximately 3.3~3.4°C), which is equivalent to 25% of the heating plate's efficiency.
