摘要: 为固体激光器设计了一种新型内部结构扰流柱结构的冷却热沉，采用计算流体力学（CFD）方法对此水冷热沉的三种典型设计方案以及传统的空腔结构和等截面小通道结构热沉分别进行了数值模拟，据此研究了冷却水流量对各种方案的增益介质最高温度、冷却面温度分布以及热沉的压力损失等特性的影响。在相同传热量和相同冷却水流量前提下，等截面小通道热沉和扰流柱热沉的传热特性都明显优于空腔结构热沉。与等截面小通道水冷热沉相比较，扰流柱热沉传热热阻更小，而流动压力损失较大。数值模拟结果表明扰流柱热沉传热性能优于传统的两种热沉（空腔结构和等截面小通道结构）设计方案，具有更好的冷却效果。在较高流量下工作时，扰流柱热沉传热性能略优于等截面小通道热沉，在较低流量下工作时则显著优于等截面小通道热沉。

Abstract: A new type of heat sink for solid-state laser, namely pin-fins heat sink, was presented. Three typical structure designs of water cooled pin-fins heat sink, as well as traditional cavity structure and invariable cross-section mini-channel heat sink, were simulated with Computational Fluid Dynamics (CFD) method. The influence of cooling water flow rate on the characteristics of these approaches, such as gain media maximum temperatures, cooling surface temperature profiles, and pressure losses of heat sinks were comparatively investigated. On the assumptions of equal heat transfer rate and equal flow rate, the heat transfer characteristics of pin-fins heat sink mini-channel heat sink were better than cavity structure heat sink remarkably. The heat transfer resistance of pin-fins heat sink is less than that of minichannel heat sink; meanwhile the flow pressure loss of pin-fins heat sink is greater. Numerical simulation results suggest that pin-fins heat sink has a better performance compared with traditional cavity structure and mini-channel heat sinks. The heat transfer performance of pin-fins heat sink is slightly better than that of invariable cross-section mini-channel heat sink at a higher flow rate, and remarkably better while at a lower flow rate.
