摘　　要：提出一种用于空气源热泵-散热器系统的涂层材料,即石墨烯复合涂料。受空气源热泵热水机组出水温度的限制,需提高散热器的散热能力。主要通过实验分析,分别制备石墨烯质量分数为0%、2.5%、5%的样品,比较喷涂前后散热器散热能力的大小。结果表明:石墨烯质量分数为5%的复合涂层的散热器散热效果最好,供水温度为50℃时,散热量约为纯环氧树脂的13倍;随着供水温度的升高,样品的散热量增加,但增加的幅度逐渐减小。A new coating material which is graphene composite coatings is proposed for air source heat pump-radiator system. Limited by the outlet water temperature of air source heat pump water heater, it is necessary to improve the heat dissipation capacity of the radiator. The samples with 0%, 2.5% and 5% graphene mass fraction were prepared and the radiator heat dissipation capacity before and after spraying was compared. The results show that the heat dissipation effect of the composite coating with 5% graphene is the best. The heat dissipation of the composite coating is about 13 times of pure epoxy resin when the water supply temperature is 50 ℃. With the increase of the water supply temperature, the heat dissipation of the sample increases, but the increasing range decreases gradually.
