多分支柔性脉动热管实验研究

Soft heat pipes have many potential applications in the thermal management of the human body and flexible electronic devices. However, the flexibility and heat transfer capability of the current soft heat pipes are limited, which cannot meet the requirements for engineering applications. In this work, according to the working principle of a pulsating heat pipe, a soft multi-branch heat pipe was fabricated by Teflon tubes, where acetone was used as the working fluid. As each heat transfer branch could deform independently, the proposed heat pipe exhibited excellent flexibility. Meanwhile, the proposed heat pipe also has high heat transfer performance with the apparent thermal conductivity being up to 4333 W·m⁻¹·K⁻¹. Therefore, the proposed soft heat pipe can contribute to the development of thermal management garments, cooling of electronic devices, low-grade waste heat recovery.
