In this paper, the frosting experiment was carried out by the wind tunnel experimental device in the single experimental section of the closed-mouth return flow. Through the experimental study on the influence of heat exchange temperature difference on the growth characteristics of the frosting layer in the finned evaporator under the experimental conditions of different initial head wind speeds, the following conclusions were drawn: At 2m/s, the frost thickness of finned tube evaporator increases gradually with the frosting time at different heat exchange temperature differences. At 3, 4, 5m/s initial face wind speed, the frost thickness of finned tube evaporator grows in a three-stage pattern at different heat exchange temperature differences. The cooling capacity of the evaporator at different face wind speeds and different heat transfer temperature differences increases first and then decreases with the frosting time.
