Computer self-starting heat dissipation device based on principle of thermal expansion and cold contraction

Abstract

The invention relates to the technical field of computer auxiliary equipment, and discloses a computer self-starting heat dissipation device based on principle of thermal expansion and cold contraction, which comprises a heat dissipation disc, a fixed bracket is fixedly connected to the inner wall of the heat dissipation disc, and a fixed sleeve is fixedly connected to the opposite end of the fixed bracket; and an adjusting bin is movably connected to the interior of the fixed sleeve, and a sliding magnetic block is movably connected to the interior of the adjusting bin. According to the computer self-starting heat dissipation device based on the principle of thermal expansion and cold contraction, the movable magnetic plate drives the telescopic rod to slide outwards along the inner wallof the air exchange bin, the thin film is gradually folded, the dust filtering net is gradually opened, the heat dissipation holes are enlarged, and hot air in the case is pumped out in cooperation with the air exchange turbine, so that air in the case and air outside the case are subjected to rapid convection; the purpose of rapid heat dissipation is achieved, the situation that dust enters the case to cover the surfaces of electronic components or block the heat dissipation holes due to long-time opening of the heat dissipation holes is avoided, and therefore the heat dissipation capacity ofa computer is reduced.

Description

technical field [0001] The invention relates to the technical field of computer auxiliary equipment, in particular to a self-starting cooling device for computers based on the principle of thermal expansion and cold contraction. Background technique [0002] A computer is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations and logic calculations. It has the function of storage and memory. It can run according to the program and process massive data automatically and at high speed. When the computer is in use, its internal CPU will generate a large amount of data. If the heat is not discharged in time, it will not only make the computer freeze, but also reduce the service life of its internal electronic components. [0003] The heat dissipation holes of traditional computers are generally fixed on the outer wall of the computer case. Dust from the external environment can easily enter the interior of the computer and a...
