Television heat dissipation device

Abstract

The invention discloses a television heat dissipation device which is high in radiating effect, noiseless, safe and reliable in work, and free of extra running expenses. The television heat dissipation device comprises an LCD television main board, a step radiating block, a strip radiating block and a heat pipe, wherein the step radiating block is fixed on one side of the television main board; the strip radiating block is arranged on the inner side of a television shell; the heat pipe is arranged between the step radiating block and the strip radiating block, and adopts a direct heat pipe in which a working medium flows back under the action of gravity; the evaporation segment of the heat pipe is arranged in a concave hole in the step radiating block; the condensation segment of the heat pipe is arranged in a concave hole in the strip radiating block. The television heat dissipation device has the advantages that aluminum production radiating fins, fan enforced heat dissipation and ceramic radiating fins are avoided, so as to overcome the detects of poor radiating effect, high noise, high running cost and the like of the conventional heat dissipation technology.

Description

technical field [0001] The invention relates to a heat dissipation device for a television, in particular to a heat dissipation device for a liquid crystal television. Background technique [0002] When the TV is working, the main board will generate a lot of heat, which requires enhanced cooling of the main board to maintain the normal operation of the TV and maintain its operation stability; secondly, to protect the TV and prolong the service life of the TV. The existing LCD TV main board helps the main board to dissipate heat by fixing the aluminum heat sink. The heat sink is fixed to one side of the main board with glue, but the aluminum heat sink is a traditional heat dissipation method, and the heat conduction is not particularly good, especially in summer. .

Problems solved by technology

The existing LCD TV main board helps the main board to dissipate heat by fixing the aluminum heat sink. The heat sink is fixed to one side of the main board with glue, but the aluminum heat sink is a traditional heat dissipation method, and the heat conduction is not particularly good, especially in summer.

There is also a fan to force heat dissipation, but this cooling method is relatively noisy, and the operation of the electric fan consumes power. In addition, the service life of the electric fan is short, and it must be replaced if it is broken, which increases additional operating costs.

Another is to use ceramic heat sink for heat dissipation. Ceramic heat sink not only has low thermal conductivity but also is easy to crack. If it is used as a heat sink, it must be made into a mesh shape. However, ceramics have high hardness and low strength, are easy to be broken, and the manufacturing cost is high.
