Abstract

The invention discloses a strong heat dissipation structure used for heat dissipation of a laser television and a preparation method thereof. The strong heat dissipation structure comprises a substrate and a strong heat dissipation film from bottom to top; raw materials of the strong heat dissipation structure include the following compositions: a heat absorbent, an intermediate coupling agent, a coolant and a protective agent, wherein the total thickness of the strong heat dissipation film is no more than 20 microns. The strong heat dissipation film utilizes a three-dimensional structure of the coolant, so that the heat transfer rate is remarkably improved; through a planar net structure of the intermediate coupling agent, the uniformity of heat conduction is guaranteed; through a large-area fold formed by the coolant and the protective agent after drying, the heat dissipation specific surface area is increased in magnitude, so that the heat dissipation effect can be remarkably promoted; meanwhile, the preparation process for the strong heat dissipation structure is simple, the thickness of the prepared film reaches micron order and the prepared film is flexible to make application of the heat dissipation film to future wearable flexible equipment and super-large scale nanometer integrated circuits and high-performance ultra-thin high-power electronic products possible.

Description

technical field [0001] The invention relates to the technical field of heat dissipation materials, in particular to a strong heat dissipation structure for heat dissipation of laser TVs and a preparation method thereof. Background technique [0002] With the requirements of modern society for electronic equipment to be light in weight, easy to carry, flexible, transparent, and integrated, the degree of integration is getting higher and higher, and electronic products are also developing in the direction of thin, light, and small, so that the surface temperature of electronic products is also constantly increasing. As electronic components urgently need a relatively low temperature environment to operate reliably, otherwise the life of electronic components will be reduced, so the heat dissipation of electronic products has become a very prominent problem. Especially in large-screen TVs such as rear-projection TVs, plasma TVs, and flat-panel TVs, which are becoming more and m...
