In the prior art, the temperature equalization plate is used for solving the contradiction, but the cost is high.
Therefore, a low-cost composite heat dissipation material which can dissipate heat of a heat source, can prolong the upward heat penetration time so as to have more time for heat conduction in the horizontal direction, has low outer surface temperature and low cost is developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing one kind can be for the heat dissipation of heat source while, can also prolong the heat penetration time that makes progress to there are more time horizontal direction heat conduction, its surface temperature is low, and the low-cost compound heat radiation material of low cost.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a low cost composite heat sink material comprising at least one graphite composite layer; the graphite combination layer comprises a graphite layer; the graphite layer is provided with a layer for reducing the thermal penetration ability; the graphite layer and the layer for reducing the heat penetration ability are bonded together through an adhesive layer; the graphite combination layers are sequentially overlapped, and the adjacent graphite combination layers are bonded together through the bonding layer.
