摘要(Abstract)：
采用实验和数值模拟的方法研究了电子设备冷却用矩形通道空芯冷板的换热特性。数值计算中 ,采用了同位网格上的SIMPLE算法和低雷诺数湍流模型 ,温度场计算中采用整场离散求解的方法。数值模拟结果与实验结果吻合良好。
Te heat transfer characteristic of rectangular channel cold-plate in electronic devices is studied with experimental and numerical simulation methods. The SIMPLER algorithm in an unstaggered grid system and Low Reynolds k-ε turbulence model have been applied in flowfield computing. The method of whole-field dispersed and solved has been used in temperature field simulation.Results of the experiment agree with results of simulation.
