Abstract

The present invention relates to technical field of electricity, and in particular to a kind of corrosion resistant type fin.A kind of corrosion resistant type fin of the present invention, graphene radiating film layer can accelerate the radiating effect and heat conductivility of fin, shorten the heat transfer time between fin and electrical equipment, improve radiating effect;The setting of corrosion-proof protection film layer can improve the decay resistance on heat sink body surface, protect graphene film layer, prevent graphene film layer from being caused impaired influence service life by physically or chemically factor;First thermal vias and the second thermal vias set the heat sinking function for substantially increasing fin;Simple and reasonable, preparation technology is simple, and production cost is low.

Description

A kind of corrosion resistant type fin
Technical field
The present invention relates to technical field of electricity, more particularly to a kind of corrosion resistant type fin.
Background technology
Fin is a kind of device to the radiating of easy heat-generating electronic elements being used in electrical equipment, and power consumption increases therewith, various Therefore electronic component also produces huge heat, electron heat-radiation belt carrys out heat dissipation problem.With high-tech development, electronic product Intelligence increasingly and complicate, the volume of electronic component tends to microminiaturization, and unit area closeness is more and more high.Existing radiating Device mostly radiating effect is bad, and it is poor barrier propterty to be present, causes graphite thermal layer easily to be damaged by physically or chemically factor The problems such as, so as to influence the service life of electronic component.
The content of the invention
The purpose of invention:The invention discloses a kind of corrosion resistant type fin.
Technical scheme:In order to realize the above object the invention discloses a kind of corrosion resistant type fin, including fin sheet Body, parallel equidistant are disposed on the fin on heat sink body end face, are arranged on heat sink body other end Radiating film layer and the corrosion-proof protection film layer for being arranged on radiating film surface;It is recessed that one is provided between the adjacent fin of each two Groove, described groove are arranged on the end face where fin;Described heat sink body be provided with some first thermal vias and Second thermal vias, the longitudinally through described heat sink body of the first described thermal vias, the second described thermal vias are horizontal The heat radiator body described to insertion, and the first described thermal vias and the second thermal vias is crisscross communicates.
Preferably, described radiating film layer is radiating graphene film layer, by sticking in fin sheet with adhesive mixing On end face of the body away from fin.
Preferably, described corrosion-proof protection film layer is CrAl/CrAlN multiple layer films, is sticked in by adhesive scattered Hotting mask layer surface.
Preferably, described adhesive is at least one in epoxy resin, polyurethane acrylic resin, Kynoar Kind.
Preferably, the thickness of described radiating film layer and the thickness of corrosion-proof protection film layer are suitable, are 3-30 μm.
Preferably, described groove is semicircular arc groove.
Preferably, the quantity of the first described thermal vias first thermal vias identical and described with the quantity of groove One end extends to corrosion-proof protection film layer outer face, and the other end extends to groove outer face.
Preferably, the diameter of first thermal vias and low-heat thermal vias is 5 μm.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that:A kind of corrosion resistant type of the present invention Fin, graphene radiating film layer can accelerate the radiating effect and heat conductivility of fin, shorten fin and electrical equipment Between heat transfer time, improve radiating effect;The setting of corrosion-proof protection film layer can improve the corrosion resistant on heat sink body surface Corrosion energy, graphene film layer is protected, prevent graphene film layer from being caused impaired influence service life by physically or chemically factor;The One thermal vias and the second thermal vias set the heat sinking function for substantially increasing fin;It is simple and reasonable, preparation technology Simply, production cost is low.
Brief description of the drawings
