Heat dissipation device of electronic and electrical equipment

Abstract

The invention relates to a heat dissipation device of electronic and electrical equipment. The heat dissipation device comprises a heat dissipation cavity and a cooling pipe; the heat dissipation cavity is of a cuboid structure, the top face of the heat dissipation cavity is connected with the top cover through a movable connecting structure, the heat dissipation cavity is of a double-layer structure, a heat dissipation groove is formed between the outer wall and the inner wall of the heat dissipation cavity, a plurality of evenly-arranged ventilation holes are formed in the inner wall of the heat dissipation cavity, and a plurality of uniformly arranged heat dissipation holes are formed in the bottom surface of the heat dissipation cavity; the heat dissipation cavity is made of a high-thermal-conductivity silica gel material, and the high-thermal-conductivity silica gel material is obtained by compounding organic silica gel and a thermal conductive material; and the thermal conductive material is composed of a thermal conductive filler, modified carbon nanotubes and a coupling agent. Blowing heat dissipation can be carried out on the periphery of the electronic and electrical equipment in the heat dissipation cavity at the same time, the heat dissipation effect is uniform, blown hot air is discharged through the heat dissipation holes in the bottom side of the heat dissipation cavity, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the field of electronics and electrics, in particular to a heat dissipation device for electronic and electric equipment. Background technique [0002] All kinds of electronic and electrical equipment currently on the market will generate heat or even generate high temperature under working conditions, and the heat dissipation method adopted by these equipment is often to use the principle of natural convection to drill holes in its casing, especially the rear casing Or slits, when the electronic and electrical equipment is working, the heat will cause the internal temperature to be too high, and various harmful elements will be released after the heat is absorbed in the shell, which will cause adverse effects on people, and the heat dissipation effect of the existing electronic and electrical equipment is not good. Well, sometimes even electronic components can be destroyed due to overheating. Contents of the invention [0...
