LHP圆盘式蒸发器的强度分析与启动预热分析

STRENGTH AND THERMAL ANALYSIS ON THE DISK EVAPORATOR OF LOOP HEAT PIPE

本文设计了一种用于回路热管(LHP:loopheatpipe)的圆盘式蒸发器,并利用ANSYS仿真软件创建三维模型,对其进行了受力分析,结果显示应力和应变分布均匀,没有明显的应力、应变集中现象发生;另外,利用FLUENT软件对蒸发器启动预热阶段进行了瞬态热分析,得到了其温度分布,结果表明,本蒸发器可以有效地降低背向导热现象,这对以后实验工作有重要的指导意义。

A new disk type evaporator used for loop heat pipe was designed in this paper.The simulation for strength analysis was taken with 3-D model created using ANSYS software,the result indicated that the strain and stress distributed uniformly and no distinct stress or strain concentration problem take place.Also the transient thermal analysis for the evaporator prior start-up was conducted, and the temperature distributions of the evaporator at different time prior startup were presented,the simulation results ...
