目前,我国空调和制冷设备上的空冷换热器大部分是采用管片式结构(光管套平片或波纹片)。这种结构没有对换热器的片表面和管内侧采取有效的强化措施,也没有考虑如何进一步减小管片间的接触热阻,因此,换热器的传热效率得不到提高。近年来,随着家用电器、车辆空调、建筑空调的发展和需求量的增加,空冷换热器的研究越来越被人们所重视,这是因为它和压缩机一样都是制冷设备中重要的组成部 At present, most of the air-cooled heat exchangers on air-conditioners and refrigeration equipment in our country adopt the pipe-slice structure (light pipe sets or corrugated plates). This kind of structure does not take effective strengthening measures on the surface of the heat exchanger and the inner side of the pipe, nor does it consider how to further reduce the thermal contact resistance between the pipe pieces, therefore, the heat transfer efficiency of the heat exchanger can not be improved. In recent years, with the development of household appliances, vehicle air conditioners, building air conditioners and the increasing demand, more and more attention has been paid to the research of air-cooled heat exchangers because it is as important as the compressor in refrigeration equipment Components
