Abstract

The invention belongs to the technical field of automobile accessories, in particular to an automotive graphene heat dissipation device and electrical equipment. The automotive graphene heat dissipation device comprises a main heat sink plate and a plurality of heat conduction columns, each heat conduction column is fixedly installed on the main heat dissipation plate; one side with each heat conduction column, of the main heat dissipation plate is sprayed with a first graphene coating; the side wall of the main heat dissipation plate is sprayed with a second graphene coating, the side wall ofeach heat conduction column is sprayed with a third graphene coating, and the end face of each heat conduction column facing away from the main heat dissipation plate is sprayed with a fourth graphene coating. Due to the extremely high thermal conductivity and thermal radiation coefficient of graphene, the graphene coating can efficiently absorb the heat transferred from the heating element to the main heat sink and the heat conduction columns, and dissipate the heat to the external environment. As such, by spraying that graphene coating on the main heat dissipation plate and each heat conduction column, the heat dissipation surface area of the automotive graphene heat dissipation device is enlarged, the heat dissipation performance is strengthened, and the overall corrosion resistance, durability and environmental protection of the automotive graphene heat dissipation device are improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a graphene cooling device for a car and electrical equipment. Background technique [0002] In automobile parts, there are often a large number of heat-generating electrical components, such as the vehicle's air-conditioning control system and headlight system, etc., and the heat emitted by the above-mentioned systems needs to be dissipated in time to ensure the stability of its operation. In this way, it is necessary to provide a heat dissipation device for the above-mentioned heat generating device. [0003] In the prior art, the heat sink is generally a die-cast integrated device. Although the heat sink with this structure can reduce the manufacturing cost of the heat sink, the die-cast bulk device has a simple structure and a small heat dissipation surface area. The heat dissipation effect is also relatively limited, resulting in poor heat dissipation performa...
