High-efficiency cooling fan for computer mainframe

Abstract

The invention relates to the technical field of computers, and discloses a high-efficiency cooling fan for a computer mainframe, comprising a frame, a mounting block is welded on the surface of the frame, the top of the mounting block is fixedly connected with a screw through a spring, and the top of the frame An adsorption mechanism is provided, the top of the frame is fixedly connected with a collection box, the inner wall of the frame is welded with a cross cover, the surface of the cross cover is fixedly connected with a spiral blade, and the top of the cross cover is provided with a guide mechanism, through The No. 1 magnet on the fan body drives the No. 2 magnet to move, which in turn causes the adsorption mechanism to frictionally generate electricity, so that the dust can be adsorbed. The adsorption mechanism can also allow the dust to enter the collection box for collection, preventing the dust from being absorbed again after being saturated. Blow out and fall on the motherboard, reduce the dust blown into the computer, prevent dust accumulation, reduce the short circuit of the computer motherboard caused by dust, and increase the service life of the computer.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a high-efficiency cooling fan for a computer mainframe. Background technique [0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logic calculations, and storage and memory functions. It is a modern intelligent electronic device that can run according to programs and process massive amounts of data automatically and at high speed. equipment. [0003] The cooling fan of the computer needs part of the fan body for air intake and part of the fan body for air return, and the air intake fan body often blows a large amount of dust into the computer, which will cause dust accumulation inside the computer after long-term use, which may cause The short circuit of the main board further leads to the problem that the computer cannot be used. Therefore, a high-efficiency cooling fan fo...
