By discussing the frosting characteristics of the finned tube evaporator surface and the effect of frost on the performance of the heat exchanger, some measures to improve the structure of the finned tube evaporator under frost conditions are proposed to reduce the frosting effect on the evaporator Adverse effects of heat exchange performance, extend the defrost cycle, save energy and raw materials. Especially for the improvement of the evaporator defroster and the change of finned tube group structure in different working temperature range
