Specific embodiment
Be directed to the description of the utility model major function:
High heat dissipation film composite construction described in the utility model comprises the first metal layer, second metal level and is arranged on the two middle high heat dissipation film.This composite construction has strengthened the flintiness of high heat dissipation film, has also improved radiating efficiency simultaneously, has strengthened its heat dispersion.
Below by for example the utility model being described.
With reference to shown in Figure 1, what show here is the schematic diagram of high heat dissipation film composite construction described in the utility model.In the present embodiment, this height heat radiation composite construction includes the first metal layer 100, second metal level 200, and is clipped in the high heat dissipation film 300 between the two.The first metal layer 100 and second metal level 200 adopt platy structure, and its material is gold or silver or copper or aluminium or tin or lead, and certain two kinds or the alloy that certain is several in these metals.Because the thermal conductivity height of these metals, be 318W/mK such as the thermal conductivity of gold; The thermal conductivity of silver is 420W/mK; The thermal conductivity of copper is 401W/mK.If high heat dissipation film 300 is arranged in these metals or the alloy, will strengthens its radiating efficiency.
Described high heat dissipation film 300 adopts high heat radiation graphite film or graphene film, in the present embodiment, be preferably high heat radiation graphite film, it in light weight, its thermal conductivity factor is 1500～1750W/mK, be the preferred high heat sink material of the utility model, the thickness of this height heat radiation graphite film is between 1 micron～300 microns.
Above-mentioned high heat dissipation film composite construction makes radiating efficiency improve greatly owing to adopted the mixed structure of metal and high heat dissipation film, in application process, because metal level has played protective effect, makes the flintiness of high heat dissipation film strengthen simultaneously.In order further to improve the radiating efficiency of this high heat dissipation film composite construction, can also perforate be set on metal level, as shown in Figure 2.In the present embodiment, on second metal level 200 perforate 201 is set, the high heat dissipation film 300 at perforate 201 places is exposed to the outside, when heat is delivered on the high heat dissipation film 300, because the rate of heat dissipation of high heat dissipation film 300 than higher, makes the heat sinking function of whole high heat radiation composite construction improve.
Need to prove that after handled through hot melt the marginal portion of the first metal layer 100 and second metal level 200, the two adhered to each other, and high heat dissipation film 300 is sealed up for safekeeping between the two, and high heat dissipation film 300 is played fixing effect.
