Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air filter, and particularly to an air filter that is effective for use in forced air-cooled electronic equipment.

[Conventional technology]

Traditionally, in electronic devices such as computers, the third
As shown in the figure, a plurality of printed circuit boards 2 on which a plurality of integrated circuit packages 1 are mounted are mounted on a casing 3, and fans 4 are attached to the top and bottom of the casing 3.
4' is generally used to perform forced air cooling.
In this case, air is often received from the air passage 5 under the floor. Air is supplied to the housing 3 from the air passage 5 by the fan 4' at the bottom of the housing 3 as shown by arrow 6.
The air flows into the interior, rises while cooling the integrated circuit package 1 inside, and is exhausted by the fan 4 at the top.

In addition, a wire mesh screen 7 is fixed to the housing 3 under the lower fan 4' to prevent burning materials from coming out of the housing 3 in the event of a fire occurring inside the housing 3. ing. Furthermore, an easily attachable and detachable air filter 8 is disposed below the screen 7 to remove dust and the like from the air flowing into the housing 3. For the air filter 8, a material is selected that has a large ability to collect dust and does not easily block the passage of air. During regular maintenance, the air filter 8 is taken out and cleaned to remove dust and the like that has accumulated on the air filter 8.

[Problem that the invention attempts to solve]

Conventionally, the air filter 8 has been used in electronic devices, but after long-term use, some of the dust that has passed through the air filter 8 may adhere to and accumulate on the screen 7 above the air filter 8. Put it away. If dust or the like adheres to the screen 7, since the screen 7 is fixed to the casing 3, it is difficult to clean it, and the cleaning is likely to be insufficient. Therefore, the cleaning of the screen 7 is insufficient,
When the screen 7 becomes clogged, there is a problem in that air cannot flow into the housing 3 sufficiently, and the integrated circuit package 1 inside the housing 3 is not sufficiently cooled.

SUMMARY OF THE INVENTION Therefore, the purpose of the present invention is to make it possible to easily and thoroughly clean dust adhering to the screen disposed inside facing the air filter, and to solve the problem of poor cooling of electronic devices caused by clogging of the screen. Our goal is to provide air filters with

[Means for solving problems]

In this invention, the casing is equipped with a screen to prevent combustible materials from coming out in the event of a fire, and a removable air filter placed on the outside facing the screen. In air-cooled electronic equipment that is configured to air-cool components of electronic equipment (such as integrated circuit packages) that are taken in from the air via an air filter and screen and housed in a housing, the air filter is installed and removed. It is attached to the side opposite to the side where you pick up the brush so that it comes into contact with the screen when you use the brush. As a result, dust and the like adhering to the screen can be easily and sufficiently cleaned by attaching and detaching the air filter, and it is possible to eliminate poor cooling of the components of the electronic device inside the housing due to the clogging of the screen.

〔Example〕

Next, the present invention will be explained below using FIGS. 1 and 2.

FIG. 1 shows an embodiment of an air filter according to the present invention applied to forced cooling type electronic equipment. In the figure, the air filter 11 is constructed as follows. That is, a handle 13 for attachment and detachment is attached to one side of the frame 12, and a brush 14 is attached to the other side of the frame 12 (the side opposite to the handle 13 side). The back side surrounded by the frame 12 is a filter portion 15. Here, the brush 14 is one that does not damage, for example, the nylon screen 7 (see FIG. 2), and the filter portion 15 is made of, for example, Everlite HR-13 manufactured by Bridgestone Corporation.

FIG. 2 is a simplified cross-sectional view showing the arrangement of each component when the air filter shown in FIG. There is. In Fig. 2, the difference from Fig. 3 is that the air filter 8 is replaced by a
This is because the air filter 11 shown in the figure is used.

The brush 14 of the air filter 11 has a length such that it comes into contact with the screen 7 above it. Therefore, by attaching and detaching the air filter 11 in the direction of the arrow 16 shown in the figure (left and right), it is possible to clean dust and the like attached to the screen 7. Then, it passes through the filter section 15,
Remove dust etc. from screen 7 using air filter 1.
It can be easily and thoroughly cleaned by attaching and detaching operations in step 1.
It is possible to eliminate the problem of poor cooling of the integrated circuit package 1, which is a component of an electronic device, caused by the clogging of the screen 7 as in the conventional case.

In the embodiments described above, a case has been described in which the air filter 11 is applied to forced air-cooled electronic equipment, but the present invention is not limited to this, and can be applied to natural air-cooled electronic equipment and other similar electronic equipment. The air filter 11 can be applied to similar types.

[Effect of idea]

As explained above, according to the present invention, the brush is attached to the side opposite to the hand holding the brush so that it comes into contact with the screen when attaching or detaching the air filter.
By attaching and detaching the air filter, it is possible to easily and thoroughly clean dust adhering to the opposing screens, and it is extremely effective, such as eliminating the problem of poor cooling of the components of the electronic equipment inside the case due to the conventional screen clogging. It has a great effect.
