Abstract

PURPOSE: To mount in close contact with both sides or a bottom of an electronic apparatus by summarizing the outdoor air suction holes at a lower surface mounting plate and providing an opening to suck the outdoor air from two directions. CONSTITUTION: Upper and lower surface mounting plates 1, 3 are covered therebetween with a back surface plate 7, two side plates 9 and a front surface plate 11. An exhaust hole 1a is formed at the plate 1, and a suction hole 3a is formed at the plate 3. A U-shaped blocking plate 13 is disposed on the plate 1, and a fan 15 is mounted on the plate 13. The edge of the plate 13 is clamped with screws at the plate 9, and an exhaust air reservoir 17 is formed in the space between the plates 1 and 13. When the fan 15 is rotated, the outdoor air is sucked from the hole 3a of the plate 3 to cool an electronic circuit between circuit boards 5, is drawn to the hole 1a and exhausted via the reservoir 17. Accordingly, an electronic apparatus can be contained and cooled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device storage device, and more particularly to a storage device having a structure for forcibly sucking in and discharging outside air to cool the electronic device.

[0002]

2. Description of the Related Art As a conventional ventilation device for storing electronic equipment,
For example, in the device disclosed in Japanese Patent Laid-Open No. Sho 58-145196, a box cover is attached to a box to which a support frame is attached to form a storage box. When you drive a fan,
Cooling air is taken in through the air intake holes provided on the side surface of the box cover, flows almost uniformly between the multiple electronic circuit boards inside, and cools evenly, and the cooling air whose temperature has risen exits from the outlet. Then, it is sucked by the ventilation fan and discharged.

[0003]

In the above-mentioned conventional apparatus, the cooling air is sucked through the intake holes provided on both side surfaces of the box cover. Therefore, there is a problem that other parts cannot be attached in close contact (close contact mounting) because a space for inhalation is required on both side surfaces. Therefore, an object of the present invention is to provide a storage device capable of storing and cooling electronic equipment and closely mounting them.

[0004]

In order to solve the above-mentioned problems, an electronic equipment storage device of the present invention covers an upper part with a top mounting plate and a lower part with a bottom mounting plate, and includes an upper mounting plate and a lower mounting plate. In between, a plurality of electronic circuit boards are supported at intervals with their length directions facing the upper surface mounting plate and the lower surface mounting plate. The upper and lower mounting plates are covered with a back plate, a side plate, and a front plate, discharge holes are formed in the upper mounting plate, and suction holes are formed in the lower mounting plate. A fan was attached to the discharge hole, the lower surface mounting plate was arranged inside the lower end portion of the side surface plate, and an opening portion was provided below the surface plate.

[0005]

The air from the outside is sucked in through the suction hole of the lower mounting plate, and is discharged by the fan through the discharge hole of the upper mounting plate. Since the side plate is not provided with an air intake port, other parts can be attached in close contact with each other. When other components are closely mounted on the bottom of the storage device, air is sucked through the opening provided below the surface plate.

[0006]

The present invention will be described below with reference to the drawings. 1 is an exploded perspective view of a storage device showing an embodiment of the present invention, FIG. 2 is an external view showing a state in which an electronic circuit board is stored, and FIG. 3 is a sectional view taken along line AA of FIG.

In the storage device of the embodiment, the upper surface is attached to the upper surface mounting plate 1.
With a lower surface mounting plate 3 and a plurality of electronic circuit boards 5 between the upper surface mounting plate 1 and the lower surface mounting plate 3 with their length directions facing the upper surface mounting plate 1 and the lower surface mounting plate 3. (That is, the circuit board 5 is set up as shown in the figure) and arranged at intervals.
Between the upper and lower mounting plates 1 and 3, there is a back plate 7, two side plates 9,
The upper surface mounting plate 1 is covered with the surface plate 11, and the discharge hole 1a is formed in the upper surface mounting plate 1.
And a suction hole 3a is formed in the lower mounting plate 3.

On the upper mounting plate 1, a U-shaped closing plate 1 is provided.
3 are arranged, and the fan 15 is mounted on the closing plate 13. An edge of the closing plate 13 is screwed to the side plate 9, and an exhaust air reservoir 17 is provided in a space between the upper surface mounting plate 1 and the closing plate 13.
Is formed.

The lower surface mounting plate 3 is located inside the lower end 9a of the side plate 9 by a distance d, and the opening 1 is formed below the front plate 11.
9 is formed.

The surface plate 11 is divided into a plurality of plate pieces 11,
An electronic circuit board 5 on which electronic equipment such as a control circuit is mounted is attached to each plate piece 11. Upper and lower mounting plates 1, 3
A guide 21 for guiding and supporting the electronic circuit board 5 is provided therein. The plate pieces 11 are lined up without a gap, and the screws 2
It is fixed to the upper and lower mounting plates 1 and 3 by 2. A connection board (not shown) is attached to the inside of the back plate 7 in the storage device, and is electrically connected to each electronic circuit board 5. The shorter one of the electronic circuit boards is attached to the short surface board 11a. A partition plate 23 for a short circuit board is installed in the housing box, and the partition plate 23 is also provided with a guide 21.

The upper end of the back plate 7 projects slightly from the side plate 9, and a mounting hole 7a is formed in the projecting part. A mounting hole 7b is formed at the lower end of the back plate 7. The housing box of this embodiment can be mounted on a wall surface or the like using these mounting holes.

When the fan 15 is rotated in the storage device as described above, the outside air is sucked through the suction holes 3a of the lower mounting plate 3, passes through the circuit boards 5, cools the electronic circuit, and is discharged. It goes out to the hole 1a and is discharged through the discharge air reservoir 17 (see the arrow in FIG. 3). This storage device can be used upright as shown in FIGS. 1 to 3, or can be used by tilting the storage device and placing the back plate 1 downward. When the back plate 1 is used downward, the side plates 9 and 9 are used.
Other parts, equipment, etc. can be closely attached to and attached to. Further, when used upright as shown in FIGS. 1 to 3, or when the bottom portion is mounted in close contact with other components, devices, etc., the outside air is introduced from the opening portion 19.

[0013]

As described above, according to the present invention,
Since the outside air intake holes are gathered in the lower surface mounting plate and the outside air is taken in from two directions so that the outside air can be sucked in from two directions, it is possible to obtain an effect that it is possible to carry out close mounting on both side surfaces or the bottom surface side.
