Abstract

The invention discloses a strong heat dissipation structure for laser TV heat dissipation and a preparation method thereof. The invention includes a base and a strong heat dissipation film from bottom to top; the raw material of the strong heat dissipation film includes the following components: heat absorbing agent, intermediate linking agent , heat dissipation agent, and protective agent; the total thickness of the strong heat dissipation film is not more than 20 μm. The strong heat dissipation film utilizes the three-dimensional structure of the heat-absorbing agent to significantly increase the heat conduction rate; the planar network structure of the intermediate connecting agent ensures the uniformity of heat conduction; The heat dissipation specific surface area is increased, which can significantly improve the heat dissipation effect; at the same time, the preparation process of the strong heat dissipation structure is simple, and the thickness of the prepared film can reach the micron level and is flexible, so that the heat dissipation film can be used in future wearable flexible devices and ultra-large-scale nanometer Integrated circuits and high-performance, ultra-thin and high-power consumption electronic products have become 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...
