Abstract

The invention discloses a cooling fin for a charging pile, and the cooling fin comprises a base layer and a coating layer. The upper surface of the base layer is uniformly coated with the coating layer, and the coating layer is provided with a plurality of heat dissipation blocks in an inclined manner. The interior of the base layer is longitudinally provided with a plurality of heat dissipation holes. The coating layer is made of graphene solution, and the graphene solution contains the following components: graphene, an adhesive, a dispersing agent, a surface active agent and an antifoamingagent. The beneficial effects of the invention are that (1), the graphene solution employed in the invention is very high in heat conductivity, the plane conduction of heat can be quickly carried outalong the graphene solution coating layer, and the heat is quickly conducted to the outside, thereby shortening the heat conduction time of the cooling fin, improving the cooling speed of the coolingfin, and reducing the internal temperature of the charging pile; (2), the cooling fin is provided with the heat dissipation blocks in an inclined manner, thereby increasing the heat dissipation area to a certain degree, and improving the heat dissipation efficiency of the interior of the whole charging pile.

Description

technical field [0001] The invention belongs to the field of charging piles, and in particular relates to a heat sink for charging piles. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. Due to the needs of current life, the demand for charging piles is getting higher and higher. [0003] As more and more people use charging piles, the charging piles are in working condition most of the time, and a lot of heat will be generated inside the charging piles. The charging piles need good cooling effect, especially in summer when the temperature is high. Timely heat dissipation will affect the use of charging piles.
