摘要:
对电子元器件散热和太阳能应用中的小热管内汽液两相流动与传热作了分析, 进行了小直径圆型和扁型热虹吸管( f4 0. 8、f6 × 0.8、8 × 1. 0mm) 传热性能试验, 热管壁面温度的波动和热管传热能力与热管内汽液两相流动及流型变化有关. 高热源温度时, 热管传输功率大, 流型为塞状流; 低热源温度时, 流型为条状流; 扁型热管传热功率比圆型热管低.
Abstract:
This paper introduces the experiment on the heat transfer performance of the circle and flat miniature thermosiphon pipes( f4 0. 8、f6 × 0.8、8 × 1. 0mm) and analyses the two- phase flow and flow pattern of liquid and vapor in the tubes. Both the tube surface temperature and the heat transfer capacity of the heat pipe have some relations with the two- phase flow and its transform during the heat pipe operating. At higher temperature of the heating source, the flow pattern is a slug flow and the heat transfer power is high. At lower temperature of the heating source, the flow in the tubes is churn flow. The circle miniature heat pipe has higher heat transfer power than the flat miniature heat pipe.
