Description

A desktop computer case

technical field

The utility model relates to the field of cabinets, in particular to a desktop computer cabinet.

Background technique

As a part of computer accessories, the chassis plays a main role in placing and fixing various computer accessories, playing a role of support and protection. In addition, the computer chassis has an important role in shielding electromagnetic radiation. Because the chassis is not like CPU, graphics card , motherboard and other accessories can quickly improve the performance of the whole machine, so it has not been listed as a key consideration in DIY. But the chassis is not useless. After some users bought a non-branded chassis, the circuit formed between the motherboard and the chassis caused a short circuit and made the system very unstable.

When selecting a computer case, not only the appearance of the case, but also the heat dissipation performance of the case should be considered. Therefore, in order to enhance the heat dissipation performance of the case, the case is provided with a ventilator connected with the air. However, the electronic components in the chassis are charged with static electricity when it is powered on, and the static electricity has a strong adsorption effect on dust, so that the dust in the air can easily enter the chassis through the vents and adsorb on the electronic components in the chassis for a long time Dust accumulated on electronic components further affects heat dissipation performance.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a desktop computer case. Dust removal nets are arranged on both sides of the case to filter out dust in the air under the premise of ensuring that the inside of the case and the outside air are easy to circulate. At the same time, when the gas passes through the dust net, the resistance is small.

The utility model is realized through the following technical solutions:

A desktop computer case, comprising a case body, the case body including a front panel and a side panel, the front panel is provided with a grid window and a spare port, the spare port is used to reserve a place for installing optical drives and other accessories, and the grille window can be To enhance heat dissipation, the side plate is provided with a dust removal net. The dust removal net includes a dust removal net body and a dust removal unit arranged on the dust removal net body. The dust removal unit is a net-shaped positive edge platform. Board fixed connection. The positive prism-shaped dust removal unit on the dust removal net has a large contact area with the air, which can reduce the resistance to gas flow.

As a preferred technical solution of the present invention, the bottom of the case body is provided with four legs, and the legs are respectively arranged at four corners of the bottom of the case body.

As a preferred technical solution of the utility model, the dust removal unit is formed by pressing a thin steel sheet after drilling holes.

As a preferred technical solution of the utility model, the bead is screwed on the side plate by screws.

Compared with the existing technology, the beneficial effect of the utility model is: the utility model is provided with a dust removal net on the side plates on both sides of the chassis body, and the dust removal unit on the dust removal net is a filter screen in the shape of a positive prism, which can Filter out the dust in the air and avoid the problem of large air resistance.
