Abstract
The utility model provides a dust guard plate used for a casing of various electrical appliances. The dust guard plate comprises a plate body. Rectangular heat dissipation holes in rectangular or circular distribution are arranged on the plate body. The bottom of each of the heat dissipation holes in the inner side of the plate body extends upward to form an oblique sheet. As the casing of the various electrical appliances, the dust guard plate can not only provide a good heat dissipation environment for casing inside but also have a good effect in terms of dust prevention.
Description
Affiliated technical field
The utility model relates to a kind of sheet material, especially, is a kind of dust excluding plate that is used for the electric equipment housing.
Background technology
For present electric equipment, as host computer etc.,, therefore have relatively high expectations for dustproof because its inside has large scale integrated circuit, in case the too much dust of accumulation in the casing for electric appliances, then various electronic components can not normally stably be worked.
Yet, consider the heat dissipation problem of electric equipment, need on the housing of electric equipment, offer louvre again, thereby guarantee good heat dissipation environment.For present casing for electric appliances, its plate body is dull and stereotyped, and it is dull and stereotyped that louvre directly runs through, so dust can directly enter casing for electric appliances by louvre, and dustproof effect is relatively poor, is easy to make a large amount of dusts of accumulation in the cabinet, thereby causes the electronic component cisco unity malfunction.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of dust excluding plate, and this dust excluding plate is as various casing for electric appliances, not only can be for cabinet inside provide good heat dissipation environment, and have the good dust-proof effect.
The technical scheme that its technical problem that solves the utility model adopts is: this dust excluding plate comprises plate body, offer the rectangle louvre of rectangular or circular distribution on the described plate body, described plate body in the plate body inboard, each described louvre bottom extends upward an oblique sheet.
As preferably, the angle of cut on described oblique sheet and described plate body plane is between 30 °-45 °.
As preferably, the described oblique sheet one of horizontal same delegation links to each other, and to improve its intensity, prevents in the touching process when mounted, and part tiltedly sheet is twisted.
The beneficial effects of the utility model are: this dust excluding plate is during as various casing for electric appliances, can make the louvre distributed areas place the position of radiator fan (then not considering of no radiator fan) below in the Box of electric machine, then the heat in the cooling cabinet can effectively be discharged by louvre, and dust enters climbing process along described oblique sheet of necessary experience in the cabinet, therefore resistance is bigger, is difficult to enter, therefore, this dust excluding plate had both guaranteed heat dissipation environment, and dustproof effect is provided again.
Description of drawings
Fig. 1 is the schematic diagram of this dust excluding plate.
Embodiment
In the embodiment shown in fig. 1, this dust excluding plate comprises plate body 1, offers the rectangle louvre 11 of rectangular or circular distribution on the described plate body 1, described plate body 1 in the plate body inboard, each described louvre 11 bottom extends upward an oblique sheet 12.
Described oblique sheet 12 can adopt welding procedure to be welded on the described plate body 1.
Above-mentioned dust excluding plate, the angle of cut on described oblique sheet 12 and described plate body 1 plane is between 30 °-45 °.
Above-mentioned dust excluding plate, described oblique sheet 12 one of horizontal same delegation link to each other, and to improve its intensity, prevent in the touching process when mounted, and part tiltedly sheet is twisted.
Above-mentioned dust excluding plate is during as various casing for electric appliances, can make louvre 11 distributed areas place the position of radiator fan (then not considering of no radiator fan) below in the Box of electric machine, then the heat in the cooling cabinet can effectively be discharged by louvre 11, and dust enters climbing process along described oblique sheet 12 of necessary experience in the cabinet, therefore resistance is bigger, is difficult to enter, therefore, this dust excluding plate had both guaranteed heat dissipation environment, and dustproof effect is provided again.
Claims (3)
1. dust excluding plate, comprise plate body (1), offer the rectangle louvre (11) of rectangular or circular distribution on the described plate body (1), it is characterized in that: described plate body (1) in the plate body inboard, each described louvre (11) bottom extends upward an oblique sheet (12).
2. dust excluding plate according to claim 1 is characterized in that: the angle of cut on described oblique sheet (12) and described plate body (1) plane is between 30 °-45 °.
