Background technique

With the development of industrial society, flourishing for the technology of various field of electronic devices and new energy field is right The heat dissipation technology of new energy field of batteries in field of electronic device and field of new energy technologies especially new energy field Development increasingly becomes the bottleneck for restricting the relevant technologies development, each in construction applications such as electronics, electric appliance and new energy batteries Connector especially heat-conducting mechanism between structure needs very strong performance, and structural requirement thermally conductive sheet needs thermally conductive, insulation, delays Punching, but concussion, impact to be avoided to cause material to be pierced and lead to short-circuit conduction simultaneously；And the thermal resistance of existing heat-conducting mechanism Also higher, thermally conductive and heat dissipation efficiency is reduced, production cost is also improved, for this purpose, it is proposed that a kind of combined high temperature insulate Layer heat-conducting silica gel sheet.

Utility model content

The purpose of this utility model is to provide a kind of laminating high-temperature insulating layer heat-conducting silica gel sheets, to solve above-mentioned background skill The problem of being proposed in art.

To achieve the above object, the utility model provides the following technical solutions:

A kind of laminating high-temperature insulating layer heat-conducting silica gel sheet, including the internal protective layer in cavity, the inside of the protective layer Wall is circumferentially connected with graphene composite layer, and the inner roof wall and inner bottom wall of the protective layer are connected with symmetrical two buffer layers, and two The opposite one end of a buffer layer is respectively connected with heat conduction silicone, the opposite one end of two heat conduction silicones respectively with gold Belong to paillon upper and lower end faces connection, the side wall of the buffer layer, heat conduction silicone and metal foil with graphene composite layer Side wall connection.

Preferably, offering on the metal foil multiple is in that matrix is distributed and is connected to two heat conduction silicones vertical Through-hole is also provided with multiple cross through hole vertical with vertical through holes on the metal foil.

Preferably, the protective layer is flexible modified poly ethylene layer.

Preferably, the buffer layer is made of elastic rubber material.

Preferably, the side wall of the protective layer offers the heat release hole being connected to graphene composite layer.

Compared with prior art, the utility model has the beneficial effects that this laminating high-temperature insulating layer heat-conducting silica gel sheet, metal Then paillon is transferred heat away from the heat transfer of absorption to graphene composite layer by the heat release hole on protective layer, The hot-fluid of metal foil is big, and the heat transfer of graphene composite layer is fast, and the two is mutually complementary, while ensure that leakproofness, so make its Insulation performance is enhanced while heat conduction and heat radiation, the security performance of electronic product has been ensured, has extended service life, is had very strong Practicability.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model metal foil schematic perspective view.
