Computer mainframe box capable of preventing dust accumulation of cooling fan

Abstract

The invention discloses a computer mainframe box capable of preventing dust accumulation of a cooling fan. The computer mainframe box comprises a case main body, case hardware, a motor, a filter plateand bolts. The top surface of the case main body is fixedly connected with a top panel. A side panel is fixedly arranged on the surface of the right side of the case main body. Case hardware is arranged on the inner surface of the case body, a dust falling groove is formed in the surface of the right side of the side panel, a mounting block is connected to the inner surface of the left side of the side panel, a motor is fixedly arranged on the inner surface of the mounting block, and a fixing column is mounted at the output end of the motor. According to the computer mainframe box capable ofpreventing dust accumulation of the cooling fan, when the air inlet fan blades rotate to dissipate heat of case hardware, introduced airflow can penetrate through the filter plate, dust is blocked through the filter plate, and the dust attached to the filter plate can also wipe the filter plate along with rotation of the air inlet fan blades, so that the effect of preventing dust accumulation of the heat dissipation fan is achieved.

Description

technical field [0001] The invention relates to the technical field related to computers, in particular to a computer main box capable of preventing dust from accumulating in a cooling fan. Background technique [0002] Computers are commonly known as computers, and computers are the most commonly used office equipment, teaching equipment, and entertainment equipment in life. Computers are devices that use electronic technology and some software systems to process data. It can be more convenient and quick to complete some required purposes, and because the use of computers has gradually become more widespread, people's lives have become closely related to computers, but the host computer is the main body part of the computer, through the internal installation of the host computer The CPU, graphics card, hard disk and optical drive and other chassis hardware can achieve the operation of the computer, but the main chassis has some disadvantages: [0003] First, the chassis ha...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a computer main box that can prevent the heat dissipation fan from accumulating dust, so as to solve the problem that the long-term operation of the box hardware proposed in the above background technology will cause the box hardware to overheat and accelerate aging or even damage; When the cooling fan is used, the suction generated by the cooling fan is likely to make the inside of the chassis contaminated with dust; when the filter plate accumulates too much dust, it will be in a saturated state and cannot inhale the airflow.
