Abstract

PURPOSE:To provide an air-cooling electronic apparatus and a mounting method with a good cooling effect in a small mounting space. CONSTITUTION:An inlet opening 23 and a discharge opening 25 for a forced cooling air are provided in a box 21. Then, an air-direction control unit 26 is provided at the discharge opening 25 for setting the direction of the air flow so that the discharged air from the discharge opening 25 is prevented from flowing directly into the inlet opening 23. Even in a small space, the discharged air at a high temperature after cooling doesn't return to the inlet opening 23. Consequently, the inside of the box 21 is cooled sufficiently and the mounting space can be used effectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-cooled electronic device in which cooling air is forcedly introduced and discharged to cool the inside, and a method for installing the same.

[0002]

2. Description of the Related Art As is well known, high integration of semiconductor devices has been remarkable in recent years, and electronic equipment in which semiconductor devices are used, such as electronic calculators and peripheral electronic equipment thereof, have high functions and are miniaturized. It has become something that has been done. On the other hand, the demands for these electronic devices have become wider, and the fields of use are also expanding. Therefore, more electronic devices are used side by side.

Further, in each electronic equipment, the heat generated by the internal electronic circuits, semiconductor devices, and the like also increases, and cooling from natural cooling to forced cooling by a blower or the like has been adopted. A plurality of such air-cooled electronic devices are generally installed and used in the same room.

A conventional technique will be described below with reference to FIGS. 8 and 9. 8 is a perspective view showing a schematic configuration of an air-cooled electronic device, FIG. 8 (a) is a perspective view of a first configuration example, and FIG. 8 (b) is a perspective view of a second configuration example. FIG. 9 is a perspective view showing a schematic installation state.

First, in FIG. 8, in the air-cooled electronic device shown in FIG. 8A, an introduction opening is provided in the lower portion of the front surface 2 of the housing 1 so that cooling air is circulated in a substantially horizontal direction as indicated by an arrow A and taken into the inside. 3 is formed, and the air taken into the upper part of the rear surface 4 is circulated in a substantially horizontal direction as indicated by an arrow B, so that the housing 1
A discharge opening 5 is formed for discharging to the outside. See also FIG.
In the air-cooled electronic device shown in (b), an introduction opening 3 for taking in cooling air inside is formed in the lower portion of the rear surface 7 of the housing 6, and an exhaust opening 5 for discharging the air taken in at the upper portion to the outside of the housing 6.
Are formed. The cooling air is taken in through the introduction opening 3 and forcibly discharged through the discharge opening 5 by a blower (not shown) housed inside the housing 1.

In the air-cooled electronic equipment shown in FIGS. 8A and 8B, a plurality of units are arranged in a row in the room 8 as shown in FIG. When the number of installed units is large, the space 11 between the columns 9 and 12 is set to a predetermined distance, and the space 13 is also set to a predetermined distance.

After that, conditioned air is sent from an air conditioner (not shown) in consideration of environmental conditions for operating the air-cooled electronic equipment installed in the room 8, and the entire room 8 is conditioned. Then, the operation of each electronic device is started while taking the conditioned air in the room 8 as the cooling air from the introduction opening 3. Further, the air whose temperature has risen after cooling is forcibly discharged from the discharge opening 5 into the room 8 and diffused, and the heat generated in the electronic device is discharged to the outside through the air conditioner.

However, in the above prior art,
For example, when the number of electronic devices to be used increases and the number of electronic devices installed in the room 8 increases, when the floor surface to be installed with the predetermined distances 11 and 13 in the room 8 disappears, the space 11 between the wall 10 and The space 13 between the rows 9 and 12 must be installed in such a manner that the space 13 is narrowed. Thus, the interval 11,
If 13 is narrowed and installed, the pressure loss of the cooling air that circulates and is exhausted in the electronic device increases, and the blowing device for forced cooling must also have a large capacity.

Further, since the intervals 11 and 13 are narrowed, the air having a high temperature after cooling, which is forcibly discharged from the discharge opening 5 of each electronic device, is only partially diffused into the room 8 and again on the surface of the wall 11. It will be reflected or taken into the introduction opening 3 as it is, and the cooling air will locally short-circuit and flow. For this reason, the internal temperature of the installed electronic device may rise, causing failure or damage of the semiconductor device or the like, malfunction of the electronic circuit, and the like, which may make the electronic device unusable.

In order to solve the above situation, the room to be installed must be made larger in accordance with the increasing number of electronic devices so that the intervals 11 and 13 can be made sufficiently wide. For this reason, the utilization efficiency of the space is low.

Further, since the electronic devices installed in the room 8 also take various forms, the positions at which the cooling air introduction opening 3 and the cooling air opening 5 are provided are different for each electronic device. In many cases, there was little freedom in designing the installation position, and it was difficult to design. In addition, when different electronic devices are added, it is difficult to design the installation positions of them.

[0012]

SUMMARY OF THE INVENTION As described above, conventionally,
When attempting to increase the number of air-cooled electronic devices installed in the room, the distance between electronic devices becomes narrower, and after cooling, the high temperature air that has been exhausted is taken in again and cooled, and the electronic devices are used. However, it is not possible to use it, or it is necessary to use a large room so that the installation intervals between electronic devices can be sufficiently wide. The present invention has been made in view of such a situation, and the object thereof is that there is no fear that it cannot be used because the inside can be sufficiently cooled even if the installation interval with the opposing one is narrow, and An object of the present invention is to provide an air-cooled electronic device and a method for installing the same, in which the installation position can be easily determined and the installation space can be used efficiently.

When installing a plurality of air-cooled electronic devices provided with a wind direction control device provided in such a manner that the exhaust air from the exhaust opening is not directly introduced into the respective introduction openings of the plurality of electronic devices. It is characterized in that so as to set the air direction by the control device.

[0014]

In the air-cooled electronic device configured as described above, a wind direction control device is provided in at least one of the air inlet and the air outlet for forced cooling so that the air flow direction can be set appropriately. Due to this, the installation method of the air-cooled electronic device is configured such that the air direction is set by the wind direction control device so that the exhaust air from the exhaust opening is not directly introduced into the respective installation openings of the plurality of electronic devices. This allows the wind direction control device to set the flow direction of the air passing through the opening in each device so that the exhaust air from the discharge opening is not directly introduced into the introduction opening, and the installation interval with the opposing one is narrow. In this case, the inside can be cooled sufficiently and there is no fear that it will not be usable, and it is easy to decide the installation position, so the installation space can be used efficiently. It becomes so that.
