摘　　要：小通道冷板作为一种有效的热控装置,已被广泛应用于高热流密度电子器件的热管理领域。文中以通道特征尺寸为2 mm的串行、并行以及射流冲击/小通道混合液冷板为研究对象,旨在获取这3种结构形式冷板的极限散热能力和流动阻力损失的差异。研究结果表明:在相同冷却工质流量条件下,3种冷板的散热功率由大到小依次为串行通道、射流冲击/小通道混合液冷板、并行通道;串行通道冷板的板内阻力损失明显大于其余两者;在综合考虑压力损失和散热性能的基础上,根据不同热源热流密度条件选择合适的冷板结构,有望满足特定应用的需求。该研究可供小通道液冷板的设计和优化参考。The micro-channel cold plate,as an effective thermal management device,has been widely utilized in the thermal management of high heatflux electronic devices.In this paper the micro-channel cold plates with channel characteristic dimensions of 2 mm in serial,parallel and jet impingement/micro-channel configurations are studied to explore the differences of their ultimate heat dissipation performances andflow resistance losses.The researchfindings indicate that under the same coolingfluidflow conditions,the heat dissipation power arrangement in descending order of three cold plates is sequentially serial channels,jet impingement/micro-channels and parallel channels.The internalflow resistance loss of the serial channel cold plate is significantly higher than the other two.By comprehensively considering pressure loss and thermal performance,selecting an appropriate cold plate structure according to different heat source heatflux density conditions holds promise in meeting the specific application requirements.This study provides reference for the design and optimization of micro-channel liquid cold plates.
