摘要
本文阐述了近年来对制冷剂在蒸发管内蒸发时强化传热的研究工作进展。不仅列出了纯制冷剂（R22）在同螺旋槽管、交叉槽管和人字形槽管内,在不同质量流速下的表面传热系数,还列出了替代混合制冷剂R407C在强化蒸发管中的表面传热系数。文中还说明了各种强化蒸发管的传热机理。
In recent years, the enhancement in heat transfer to refrigerant flowing inside horizontal evaporator tubes have been studied. This paper illustrates not only the test results of pure refrigerant R22 evaporating in spirally grooved, cross - grooved and herringbone tubes, but also the results of replacing refrigerant R407C evaporating in these enhanced tubes. In this paper the mechanism of heat transfer in each tube is briefly described.
