Abstract

The present invention relates to a heat sink with a graphene coating, which comprises a heat sink body, fixed connection holes are provided on the front surface of the heat sink body, heat-dissipatingfins are evenly spaced in the front surface of the heat sink body between the fixed connection holes, a heat-dissipating contact boss is provided opposite to the heat sink body, a U-shaped opening isprovided in a middle portion of one side of the heat sink body, the heat sink body, the heat-dissipating fins and the heat-dissipating contact boss are integrally formed, and a graphene coating is provided on the surfaces of the heat sink body, the heat-dissipating fins and the heat-dissipating contact boss. According to a heat sink with a graphene coating of the present invention, heat-dissipating and cooling is effectively accelerated, and the service life of the electrical device is greatly improved.

Description

technical field [0001] The invention relates to a heat sink, in particular to a graphene-coated heat sink. Background technique [0002] In a projector, as the density and power intensity of electronic devices increase, more heat will be generated during operation. In order to dissipate heat as quickly as possible, metal heat sinks are usually installed. However, the heat radiation coefficient of the metal surface is very low. Without convective heat transfer, the heat collected on the metal surface is difficult to dissipate, thus limiting the use effect and service life of some electrical devices. [0003] Graphene is a newly discovered nano-carbon material with only one carbon atomic layer in recent years. It has low density, weak chemical activity, fast heat conduction speed, high specific surface area and large infrared radiation rate. Compared with other heat-dissipating fillers in granular form, it is easier to form a heat-conducting network, and is an ideal functiona...
