摘要

采用有限元方法对两相流的单层逆流微通道散热器的热性能进行了分析。测定了两相流SLCF散热器的热阻、压降和温度分布等参数，并与两相流单层平行流(SLPF)散热器进行了比较。研究发现，微通道散热片中的两相流通常产生较低的热阻和较好的流向温度均匀性。研究还发现，SLCF微通道散热片的热性能优于SLPF散热片，特别是在较高的基片热通量条件下

Thermal analysis of single layer counter flow heat sinks with two phase flow

The thermal performance of single layer counter-flow (SLCF) microchannel heat sinks with two-phase flow have been analyzed using the finite element method. Parameters such as the thermal resistance, pressure drop and the temperature distribution in SLCF heat sinks with two-phase flow have been determined and compared with those for the single layer parallel flow (SLPF) heat sinks with two-phase flow. It is observed that two-phase flow in the micro-channel heat sinks generally yield low thermal resistance and better temperature uniformity in the stream-wise direction. It is also observed that the thermal performance of the SLCF microchannel heat sinks are better especially at higher base heat fluxes compared to the SLPF heat sinks working under similar conditions
