| 中文摘要: |
| 气体冷却器是汽轮发电机通风冷却系统的重要设备.其性能直接影响汽轮发电机的通风冷却效果及设备的运行可靠性.介绍了几种不同翅片形式(平直片、波纹片、条缝片、百叶窗片、穿孔片)的穿片式气体冷却器的换热和阻力特性的研究进展.通过对前人研究成果的归纳和总结,指出了以往研究的一些不足. |
| 英文摘要: |
| The gas cooler is one of the important equipment in the ventilating and cooling system for turbo-generators. Its performance will directly affect the ventilating and cooling effectiveness and operating reliability of turbo-generators. In this paper, advances in the research of the heat transfer and friction characteristics for different plate fin-and-tube gas coolers are introduced. Based on the discussion, the deficiency of the previous investigations is pointed out. |
