Problems solved by technology

In the prior art, most hardware backplanes have many structural layers, many processes, and high cost. Because the thermal conductivity of polymer materials is generally low and cannot effectively dissipate heat, the heat generated by the operation of the TV cannot be effectively exported. The resulting high temperature will affect the stability of the material, leading to accelerated aging of the TV, making it difficult to meet the 10-year lifespan

Abstract

The invention discloses a heat dissipation device for a video advertisement, and the device comprises a metal heat conduction layer, an organic insulating layer located at one side of the metal heat conduction plate layer, a weather-proof coating located at one side of the metal heat conduction layer, and a black coating layer disposed on the organic insulating layer in a coating manner. The organic insulating layer comprises the raw materials by weight: 80-100 parts of polyimide, 6-15 parts of silane coupling agent modified titanium dioxide, 6-15 parts of a silane coupling agent modified heat conduction filling material, and 1-3 parts of catalyst. The black coating layer comprises the following materials by weight: 40-80 parts of carbon materials, 20-30 parts of an adhesive, and 10-40 parts of solvent. The metal heat conduction plate layer enables the heat generated by a television set in an operation process to be timely dissipated outside, guarantees the working efficiency of the television set, reduces the number of layers, and reduces the interface thermal resistance. The black coating layer is good in heat dissipation, is low in cost, and is convenient to manufacture.

Description

technical field [0001] The invention relates to the field of hardware materials, in particular to a heat dissipation device used in video advertisements. Background technique [0002] The TV back panel is a very common metal plate, mainly used for the back of the TV. It is not seen by people, so it is easy to be ignored by people. If the components are damaged, the core components of the TV will be exposed, which is not conducive to the components themselves, and also poses certain safety hazards, such as electric shock and other dangerous situations. According to the level of modern technology, the service life of the TV hardware backplane should be at least 10 years. In the prior art, most hardware backplanes have many structural layers, many processes, and high cost. Because the thermal conductivity of polymer materials is generally low and cannot effectively dissipate heat, the heat generated by the operation of the TV cannot be effectively exported. The resulting high...
