1 引言 强化传热技术学科已发展到对应用于换热器有很多实际意义的阶段。工业上使用强化技术有两个目的:获得紧凑的且廉价的换热器;增加换热器的换热量。高换热量可通过两种方式开发出来:在流体入口温度一定条件下增加换热率;降低换热器的平均温差。如此可构成热力学过程效率的增强,从而节省运行费用。
1 Introduction Enhanced heat transfer technology has been developed for the heat exchanger has many practical significance stage. The industrial use of fortification has two purposes: to obtain a compact and inexpensive heat exchanger; to increase the heat transfer of the heat exchanger. High heat exchange can be developed in two ways: increase the heat transfer rate under certain conditions of the fluid inlet temperature; reduce the average temperature difference of the heat exchanger. This constitutes an increase in the efficiency of the thermodynamic processes, thereby saving operating costs.
