本文介绍了研制过程中一种由带弧形表面凸起物的换热板所组成的，间接蒸发制冷板型换热器的热工特性，主要研究了影响换热效率E，板面水温及热流密度的影响因素，实验研究表明：换热器效率受喷水的水／气比值影响不大，受迎面风速影响较大，一次风干球温度的提高使得换热器效率及热流密度均有所提高，本组换热片换热效率在一定长度下，在二次风／一次风之比为0．8时，为0．80左右，文中分析了能效比EER在各种情况下的变化。
In this paper, the thermal characteristics of an indirect evaporative cooling plate heat exchanger consisting of heat exchange plates with curved surface protrusions are introduced in the course of development. The effects of heat exchange efficiency E, surface water temperature and The experimental results show that the efficiency of the heat exchanger is not affected by the water / gas ratio of the water jet, which is greatly affected by the oncoming wind speed. The increase of the temperature of the air dry bulb results in both the heat exchanger efficiency and heat flux density Improve the heat exchange efficiency of this group of heat exchangers in a certain length, in the secondary air / primary air ratio of 0.8, about 0.80, the paper analyzes the energy efficiency EER changes in various circumstances.
