Efficient heat dissipation structure of large-size high-power ultra-thin liquid crystal display (LCD) television

Abstract

The invention discloses an efficient heat dissipation structure of a large-size high-power ultra-thin liquid crystal display (LCD) television. The structure comprises a bar-shaped hollow heat dissipation frame, at least one axial fan, and a bar-shaped heat tube temperature equalizing bar, wherein the hollow heat dissipation frame is mainly formed by a casing 3 and a heat dissipation aluminum platein an enclosing manner; the heat tube temperature equalizing bar is fixed at the top end of the heat dissipation aluminum plate in the length direction of the hollow heat dissipation frame; the axialfan is fixed on the inner side surface of the casing and is arranged right opposite to the inner side surface at a certain interval; and a plurality of vent holes are uniformly formed in positions ofthe bottom and the side surfaces of the casing where the axial fan is mounted. The structure provided by the invention has the advantages that space partition plates and the axial fan are combined for partitioned heat dissipation, so that an LED light bar can achieve good cooling effect even under the conditions of a small space, a small air volume and low noises, temperatures of light beads on the LED light bar tend to be identical through the temperature equalization effect of the heat tube temperature equalizing bar, and the overall heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal television equipment, in particular to a high-efficiency heat dissipation structure of a large-size high-power ultra-thin liquid crystal television. Background technique [0002] With the advancement of technology, LCD TVs are becoming thinner and thinner. The ultra-thin design of LCD TVs will inevitably lead to the compression of some chips and components, reducing the space for heat dissipation. Especially for LED TVs, as the size increases, the required The number of LED backlights will also increase, resulting in an increase in heat generation and the problem of uneven temperature of each lamp bead, which is very detrimental to the stability of product performance. At present, most of the materials used for uniform temperature are heat pipe products, but The manufacture of large-sized flattened long heat pipes is difficult. Narrow space, high calorific value, must be cooled by forced c...
