一、前言 水平管内沸腾换热的热交换器应用十分广泛。如动力装置中的蒸发器、制冷装置中的干式蒸发器等。为有效地节约能源、减少材料消耗,深入研究强化水平管内沸腾换热及开发高效换热管就成为迫切的需要。水平管内受迫对流沸腾换热,是一复杂的换热过程。采用强化措施后,使得从机理上分析及理论求解异型水平管内对流沸腾换热过程更加困 First, the introduction The level of boiling heat exchanger tube heat exchanger is widely used. Such as the power plant in the evaporator, refrigeration unit in the dry evaporator. In order to save energy and reduce the material consumption effectively, it is urgent to further study the boiling heat transfer enhancement and the development of high efficient heat transfer tubes. Horizontal tube forced convection boiling heat transfer is a complex heat exchange process. The use of strengthening measures, making from the theoretical analysis and theoretical analysis of heterogeneous horizontal tube convection boiling heat transfer process more difficult
