Description

Silicone Heat Resistant Sheet {SILICON RADIATION SHEET}

The present invention relates to a silicon heat dissipation sheet, and more particularly, to a silicon heat dissipation sheet attached between a display panel and an aluminum heat dissipation plate, and attaching a silicon heat dissipation sheet having a thin copper plate to the rear surface of the display panel. Thus, the present invention relates to a silicon heat dissipation sheet which transmits heat to the aluminum heat sink in the form of diffusing heat generated in the display panel so that heat transfer can be performed quickly.

In general, PDP TVs, notebook computers, and LCD TVs are typical products to which a display panel is applied. Among them, PDP (Plasma Display Panel), which generates a large amount of heat, is an apparatus for displaying an image using plasma generated by gas discharge. It uses flat glass, so that the screen is not bent and no distortion like the CRT, and the use of flat glass makes a thin wall monitor, which enables light wall-mounted TVs.

In recent years, the size and thickness of PDP display devices have been recognized as technology, and the competition is intensifying. As a result, the PDP display device has a poor thermal structure due to the narrower structure than the CRT display. The fan has been widely used as a cooling device for the PDP display device, but this is the biggest obstacle to the thinning of the thickness of the PDP display device, and also has the problems of noise, weight increase and power consumption. There is a need for a non-powered cooling device in which a fan is not used in the PDP display device. Accordingly, a heat sink made of an aluminum heat sink capable of rapidly spreading and uniformly transferring heat generated in the PDP panel to a low temperature part is used.

A heat dissipation sheet is attached between the PDP panel and the aluminum heat dissipation plate, and the amount of heat dissipation depends greatly on the heat conduction ability of the heat dissipation sheet.

The most widely used heat dissipation sheet is mainly a heat dissipation sheet made of silicon in which thermally conductive pillars such as alumina, zinc oxide, aluminum hydroxide, silicon carbide, magnesia, and boron nitride are used.

The heat dissipation sheet for a conventional display panel configured as described above serves to move the heat generated from the display panel to the aluminum heat sink, but merely serves to move the heat generated from the display panel to the aluminum heat sink. There was a problem in that it does not move quickly generated heat due to the lack of diffusion function.

In other words, the heat generated from the display panel can be vertically moved to the aluminum heat sink, but the heat spreading sheet itself cannot be spread in the horizontal direction, so it is merely a means of transferring heat, thereby effectively removing the heat generated from the display panel. There was a problem acting as a factor that inhibits the life of the product does not diverge.

Accordingly, the present invention has been invented to solve the above problems, the present invention consists of five layers, bar release paper 10 is formed in the form of a thin film at the lowest portion, the release paper 10 The upper portion of the thermally conductive silicone sheet 20 having a self-adhesive is formed, the upper surface of the thermal conductive silicone sheet 20 is formed of a copper plate 30 to a thickness of 10 to 100㎛, the copper plate 30 The upper surface of the self-adhesive and thermally conductive silicone sheet 40 is formed, the upper portion is composed of a strip form in which the release paper 50 is sequentially stacked in a thin film form.

According to the present invention configured as described above, the copper plate is formed in a thermally conductive silicon sheet, and the heat generated in the display panel is diffused in the planar direction by the copper plate by attaching between the aluminum heat sink and the display panel. The heat transfer is quickly performed by being transferred to the aluminum heat sink.

In addition, by incorporating a copper plate on the thermally conductive silicon sheet, the shape of the silicon heat dissipating sheet can be maintained as it is, so that even if exposed to heat for a long time, there is another effect of helping the life of the product without sagging or thermal deformation.
