Description

A dust-proof computer case

technical field

The utility model belongs to the technical field of computers, in particular to a dust-proof computer case.

Background technique

During the use of the computer main box, a large amount of dust will accumulate inside it. Too much dust will lead to problems such as poor heat dissipation, leakage on the surface of the circuit board, fan failure, and poor contact of the connectors. Therefore, it is necessary to regularly disassemble and clean the internal dust. Dust work is troublesome and often forgotten, so how to improve the dustproof performance of the computer case is the direction of our research. The main cause of host dust is the cooling fan. The fan is a component equipped with almost every computer. It is used to accelerate the air flow to take away the heat of the components. When the fan allows the air to take away the heat, the dust in the air is also blown to the radiator, so the computer There is more dust inside than other appliances.

Utility model content

Detailed ways

A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figures 1-4, a dust-proof computer case provided by an embodiment of the present invention includes a mainframe case 1 and a filter case 2 fixed on one side of the mainframe case 1. The rear side of the filter case 2 is connected to the mainframe case. 1 is hingedly connected, its front side is detachably connected to the host chassis 1, the rear side of the filter box 2 is hingedly connected to the host chassis 1 through hinges, and its front side is detachably connected to the host chassis 1 through a snap lock 7, through With this setting, the filter case 2 can be opened quickly, and the dust filter 3 can be replaced and cleaned. The filter case 2 is provided with a dust filter 3, and the host case 1 is provided with an air inlet 4 that communicates with the filter case 2. The air outlet 4 corresponds to the position of the main board installation area, so that the incoming cold air can pass through the main board in large quantities, and the heat dissipation capacity of the main board is improved. .

The air inlet 4 is provided with a deflector 8. The deflector 7 can guide the incoming cold air to the main board area that is easy to generate heat, and can also improve its heat dissipation capacity to a certain extent. The deflector 8 is sound-absorbing. The sound-absorbing material is sound-absorbing rock wool, which can reduce noise.

The dust filter 3 is detachably fixed in the filter case 2, and the dust filter 3 is embedded in the filter case 2, so that the dust filter 3 can be easily disassembled.

The above disclosures are only a few specific embodiments of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
