The Pulsating Heat Pipe (PHP) is more and more popularity for the increasing demand of heat dissipation. This work proposed the novel structure with connected-path to achieve the purpose of split-flow of working fluids. Furtherly, it numerically studied the thermal performance of PHP with different structures. For the first, the geometric model was established in ANSYS Workbench and the VOF model was employed to capture the distribution of interface of gas-liquid phases. Then, it numerical investigates the effect of the different inclination angles of connected-path on the heat transfer performance by the Fluent. The results indicated that the heat transfer efficiency per unit heat increased 193.03%, and the thermal resistance decreased 65.59% of the PHP with the 45° inclination angle of connected-path. However, the operation performance of PHP with connect-path would deteriorate at the 30° and 60° inclination angle of connected-path.

连通路径脉动热管的数值模拟

脉冲热管(PHP)随着对散热的日益增长的需求而越来越受欢迎。这项工作提出了一种具有连通路径的新颖结构,以实现工作流体分流的目的。此外,它还对具有不同结构的PHP的热性能进行了数值研究。首先,在ANSYS Workbench中建立了几何模型,并使用VOF模型来捕获气液相界面的分布。然后,数值研究了Fluent对连通路径不同倾角对传热性能的影响。结果表明,当连接路径的倾角为45°时,每单位热量的传热效率提高了193.03%,而热阻降低了PHP的65.59%。然而,
