本文主要研究了具有整体分级分支通道的多通道微通道冷板的单相热流体性能。使用多物理拓扑优化技术的研究微通道结构的发展进行了简要回顾。然后描述实验测试设置，随后测量温度和压力结果。具体而言，单位热阻和压降值的分层微通道射流冲击冷板的平板射流冲击的相应结果进行了比较。这些实验证实，与标准平板系统相比，分级微通道系统提供了增加的传热，而压降的变化可以忽略不计。
This article is focused on experimental investigation of the single-phase thermal-fluid performance of a manifold microchannel cold plate with integral hierarchical branching channels. The use of a multiphysics topology optimization technique for the development of the studied microchannel structure is briefly reviewed. An experimental test setup is then described followed by measured temperature and pressure results. Specifically, unit thermal resistance and pressure drop values for the hierarchical microchannel jet impingement cold plate are compared with corresponding results for the jet impingement of a flat plate. These experiments confirm that the hierarchical microchannel system provides increased heat transfer with a negligible change in pressure drop when compared with the standard flat plate system.Copyright © 2011 by ASME
