Heat-dissipation sheet assembly manufactured by using electrochemical method

Abstract

There is provided a heat-dissipation sheet assembly comprising a heat-dissipation sheet layer having good heat conductivity and a protection layer(s) electrodeposited on one or both sides of the heat-dissipation sheet layer. When the heat-dissipation sheet layer is immersed in an aqueous solution for electrodeposition added with a material for electrodeposition and electric current is permitted to flow in the aqueous solution, the protection layer(s) is electrodeposited on the one or both sides of the heat-dissipation sheet layer. The heat-dissipation sheet assembly can be attached to a heat-generating unit by applying an adhesion layer to an underside of the heat-dissipation sheet assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2013-0069480, filed on Jun. 18, 2013, the disclosure of which is hereby incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a heat-dissipation sheet assembly and more particularly, to a heat-dissipation sheet assembly manufactured by using an electrochemical method.[0004]2. Description of the Related Art[0005]Recently, the structural complexity and preciseness have more and more increased in various electrical and electronic equipment including televisions, computers, medical devices, office equipment, communication equipment, etc. As the electrical and electronic components which are used in these devices and equipment have become smaller in size and the quantity thereof has increased, the heat generated in these components has increased. To efficiently release and disperse t...

AI Technical Summary

Benefits of technology

The present invention provides a heat-dissipation sheet assembly that can prevent damage to the heat-dissipation sheet layer and maintain separation between layers even with repetitive heat generation. The assembly has a simple structure and excellent heat dissipation and dispersion effects. Additionally, the assembly may include an adhesion layer for easy attachment to the heat-generating unit and a release paper for easy detachment.

Problems solved by technology

Recently, the structural complexity and preciseness have more and more increased in various electrical and electronic equipment including televisions, computers, medical devices, office equipment, communication equipment, etc.

Furthermore, if the heat-dissipation sheet assembly 90 is inadvertently pulled or intentionally removed from the heat-generating unit 1 for repairing / checking a device or equipment, the heat-dissipation sheet layer 91 may be peeled off or damaged.
