Summary

The heat transfer process of automobile air-conditioner evaporators without hydrophilic film was analysed. It is suggested that hydrophilic film can affect the heat transfer performance of automobile air-conditioner evaporators from three aspects, i.e., effective heat transfer area, heat transfer coefficient and temperature difference. Effective heat transfer area coefficient was proposed and measured experimentally. A mathematical model was established to simulate the heat transfer processes of both the evaporator plating with hydrophilic film and the one without hydrophilic film, and the model was verified by experiments. The results show that the heat transfer coefficient decreases but effective heat transfer area and temperature difference increase, and thus the total heat transferred increases by 5% for the evaporator plating with hydrophilic film.
