The copper tube and fin in the fin-tube heat exchanger of air conditioning are not completely in contact,and the contact state will affect the heat transfer of the heat exchanger.The gap thickness was one of the main factors affecting the heat transfer,and the gap thickness and the ratio of contact length were taken as the index of contact state.The simulation results show that with the decrease of gap thickness and the increase of contact length proportion,the more heat transfers from the copper tube to the fin,the higher the fin distribution temperature and the better the heat transfer effect.
