NOVELTY - The utility model provides a heat abstractor coating structure of metal radiator. The heat abstractor coating structure is made of two layer or more than double layer of high heat radiating material layer, the high heat radiating material layer is made of heat abstractor and electrophoresis resin. The obtained ulti-layer coating heat abstractor of the utility model, providing with features such as uniformly coating, good compactness, strong heat abstractor ability, and good combination with substrate. The coating preparing technology is of simple operation, low cost and high material use rate. The utility model is widely applied to new microelectronics element and lighting lamp area.
