Abstract
The invention discloses a heat radiation composite board. The composite board comprises a carbon fiber layer, a phenolic resin membrane and a silver-tungsten alloy substrate, wherein the phenolic resin membrane is coated on the silver-tungsten alloy substrate, the carbon fiber layer is coated on the phenolic resin membrane, and the thickness of the phenolic resin membrane is smaller than that of the carbon fiber layer. According to the technical scheme provided by the invention, a silver-tungsten alloy with good heat dissipation is taken as a basic material, and based on this, the two membrane materials with excellent performance, i.e., the carbon fiber layer and the phenolic resin membrane are coated, such that the overall heat dissipation performance of the composite board is remarkably improved, and at the same time, the structure is not too complex. Besides, the composite board is easy to machine and form, and housings of such devices as a generator, a motor and the like can be quite conveniently further machined by use of the composite board. The innovative technical improvement provided by the invention realizes an outstanding heat dissipation effect, at the same time, the cost is quite low and the realization is easy. Therefore, the application prospect is good.
Description
Technical field
The present invention relates to materials science field, be specifically related to a kind of heat radiation composite plate.
Background technology
Sheet material is basic material important in productive life, and the difference according to use occasion needs sheet material to have different performances.In mechanical device, usually need sheet material to have good heat dispersion, such as, larger device is produced for the heat such as generator, motor, if material heat dispersion is not good, easily affects result of use, even cause danger.The sheet material of single material still Shortcomings in radiating efficiency in prior art, and the heat radiation sheet material developing a kind of composite material will be expected to solve this problem.
Summary of the invention
The present invention is intended to the technological deficiency for prior art, provides a kind of heat radiation composite plate, to solve the technical problem that in prior art, sheet material radiating effect is not good.
For realizing above technical purpose, the present invention by the following technical solutions:
A kind of heat radiation composite plate, comprise carbon fiber layer, phenolic resin film, silver tungsten substrate, wherein phenolic resin film is coated on silver tungsten substrate, and carbon fiber layer is coated on phenolic resin film, and the thickness of described phenolic resin film is less than the thickness of carbon fiber layer.
As preferably, the conductive coefficient of carbon fiber layer is 1.2W/ (mK).
As preferably, the thickness of silver tungsten substrate is 50 ~ 80 times of carbon fiber layer and phenolic resins film thickness sum.
In above technical scheme, material based on the good silver tungsten of thermal diffusivity, be coated with the membrane material of carbon fiber layer and phenolic resin film two kinds of function admirables on this basis, composite plate integral heat sink performance is significantly promoted, structure can not be caused too complicated simultaneously.In addition, composite plate of the present invention is easy to machine-shaping, processes the shell of the device such as generator, motor further more for convenience with it.The present invention achieves outstanding radiating effect with the technological improvement of novelty, simultaneously cost lower, be easy to realize, therefore application prospect is good.
