高综合传热系数和低阻力系数是换热器的基本要求

BASIC REQUIREMENT FOR HEAT EXCHANGER-HIGH COMPLEX HEAT TRANSFER COEFFICIENT AND LOW RESISTANCE COEFFICIENT

高综合传热系数和低阻力系数是换热器的重要经济技术指标。文中指明提高综合传热系数和降低阻力系数的原理，提出高综合传热系数和低阻力系数并不是不相容的一组对抗性的矛盾，研制一种高综合传热系数和低阻力系数同时共存的换热器是可能的。并介绍了实现高综合传热系数和低阻力系数的各种技术措施。指出高综合传热系数和低阻力系数是换热器的发展趋势。

High complex heat-transfer coefficient (HCHTC) and low resistance coefficient (LRC) is the important economic technical indexes for heat-exchanger, To realize HCHTC and LRC, various measures are introduced. It is also shown that the HCHTC and LRC is the trend for development of heat-exchanger.
