ABSTRACT

This study reports the results of experimental and numerical investigations on the thermal performance of a miniaturized phase change material (PCM) heat sink coupled with heat pipe. Initial studies are conducted on two different configurations of PCM heat sink with heat pipe (i) HSHP (i.e., PCM coupled at evaporator of heat pipe) (ii) HPHS (i.e., PCM coupled at condenser of the heat pipe). The results showed a superiority of HSHP over HPHS by up to 98.8% in the charging cycle. Experiments are conducted on HSHP with different melting temperature PCMs. The HSHP with high melting temperature PCM showed high thermal performance.

摘要

本研究报告了对与热管结合的小型相变材料 (PCM) 散热器的热性能进行实验和数值研究的结果。初步研究是对带有热管的 PCM 散热器的两种不同配置进行的：(i) HSHP（即耦合在热管蒸发器处的 PCM）（ii）HPHS（即耦合在热管冷凝器处的 PCM）。结果表明，在充电周期中，HSHP 比 HPHS 的优越性高达 98.8%。在具有不同熔化温度的 PCM 的 HSHP 上进行了实验。具有高熔化温度 PCM 的 HSHP 显示出较高的热性能。
