摘要(Abstract)：

为研究类菱形肋片流道印刷电路板换热器热工水力特性，采用数值模拟方法，以冷侧超临界二氧化碳（S-CO_2）和热侧气态CO_2为工质，分析了冷侧进口温度313.15～353.15 K，热侧进口温度553.15～593.15 K，冷热侧热工水力特性的变化，比较了NACA0030翼型肋片流道和类菱形肋片流道的综合性能。结果表明：S-CO_2入口温度增大40.0 K，总换热量减小23.91%，冷、热侧压降分别增大29.95%、11.14%；气态CO_2温度增大40.0 K，总换热量增大16.40%，冷、热侧压降分别增大9.42%、7.43%,S-CO_2入口温度变化对热工水力特性的影响更明显；类菱形肋片流道印刷电路板换热器有着更小的流动阻力和较好的综合性能。该研究结果对间断型印刷电路板换热器设计有一定的参考意义。
