Technical field

The utility model is related to a kind of Environment-friendlycorrosion-resistant corrosion-resistant antistatic high temperature resistant heat sink.

Background technology

Fin is a kind of device of the easy heat-generating electronic elements radiating in electrical equipment, more by aluminium alloy, brass or bronze Make tabular, sheet, splintery etc., cpu central processing unit will use power supply in sizable fin, television set in such as computer Power tube in pipe, row pipe, amplifirer will use fin.General fin in use will be in electronic component and fin Contact surface applies last layer heat-conducting silicone grease, the heat that component is sent more effectively is transmitted on fin, then is dissipated through fin It is dealt into surrounding air.

Conventional fin material is copper and aluminium alloy at present, and the two respectively has its advantage and disadvantage.The thermal conductivity of copper is good, but price More expensive, difficulty of processing is higher, and weight is excessive(Many fine copper radiators have been above limitations of the CPU to weight), thermal capacity is smaller, And easily aoxidize.All it is that the aluminium alloy used could provide enough hardness, aluminium is closed and fine aluminium is too soft, it is impossible to directly use The advantage of gold be it is cheap, it is lightweight, but thermal conductivity will be far short of what is expected than copper.Some radiators just respectively take the chief, are closed in aluminium Embedded a piece of copper coin on golden foot of radiator.

Because fin thickness is relatively thin, it is typically placed on plate body and constitutes heat sink, however, existing heat sink was being used Cheng Zhong, it will usually the situation that fixation departs from thermal source built on the sand occur, in addition, existing heat sink is connect due to long-time with thermal source Touch, it may appear that the situation that burn into electric leakage is even damaged.

For heat sink, the current country is primarily present following patent document:

Chinese patent Authorization Notice No.:CN205812625U, discloses a kind of metallic heat radiating plate structure, consists predominantly of one Metal base, metal coating layer and graphite linings, wherein distinguish deposited metal coating layer in the upper and lower end face of the metal base, then at Two metal coating layer surfaces difference deposited graphite layer;Whereby, using the surface texture and metal coating layer of metal base, height can be made Purity graphite is securely joined with metal base, and the carbon film formed by graphite linings, with good thermal conductivity characteristic, therefore is made The radiating effect for greatly improving electronic product with that can be reached in implementation, can also increase the service life.Although however, the heat sink has There is a preferable radiating effect, but the use of its metal and graphite, it is respectively provided with good electric conductivity so that the heat sink can not Used for a long time on electrical equipment, influence its scope of application.
