中文摘要

本文提出了一种采用低全球变暖潜势制冷剂R1234yf的双相流微通道热管理系统(MTMS)。通过将热测试芯片嵌入基板并连接至铝制微通道散热器,实现了高效散热。研究表明该系统在超过500 W/cm²的高热流密度下表现出优异的冷却性能,为高功率密度电力电子器件的散热提供了有效解决方案。

English Abstract

In this article, a microchannel thermal management system (MTMS) with the two-phase flow using the refrigerant R1234yf with low global warming potential is presented. The thermal test vehicles (TTVs) were made of either single or multiple thermal test chips embedded in the substrates, which were then attached to the MTMS. The system included two identical aluminum microchannel heat sinks (MHSs) co...
