Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention suitably performs heat radiation processing of a rack mount device when a rack mount device having a cooling air flow in the left and right direction of an electronic device is mounted on a rack having no ventilation hole on a side surface. And a cooling structure for the rack mount device.

[0002]

2. Description of the Related Art FIG. 5 shows a mounting diagram of a rack mount device. When a system is configured by incorporating electronic devices in racks, a plurality of racks 41 may be installed adjacent to each other in the horizontal direction and a rack mount device 51 may be mounted on each rack 41 as shown in FIG. Many. For this reason, as shown in FIG. 2B, the passage of the cooling air of the rack mount device mounted on the rack is generally in the front-rear direction, and the cooling air is sucked in from the front of the rack mount device 51. Warm air is exhausted to the outside of the rack 41 through ventilation holes 46 formed on the rear surface of the rack 41. It is to be understood that the air flow between the racks 41 is blocked by the side cover 42 of the rack 41.

However, as shown in FIG. 6 (a), when the rack 41 is installed alone or when a rack or the like is not installed adjacent to the rack 41, a rack having a cooling air passage in the horizontal direction may be used. is there. That is, as shown in FIG. 6B, the cooling air is taken in from the ventilation holes 46 formed in one side cover 42 of the rack 41 and the warm air is sucked into the other side cover 4.
The air is exhausted to the outside of the rack 41 through the ventilation holes 46 formed in the second rack 2.

[0004] As described above, in most rack mount devices dedicated to rack mount, a passage for cooling air is generally formed in the front-rear direction of the device. However, in order to cope with a rack having a cooling air passage in the lateral direction, there are rack mounting devices dedicated to rack mounting, in which the cooling air passage is formed in a direction other than the front-rear direction of the device, for example, the left-right direction of the device. .

The structure of the rack 41 in mounting the rack mount device shown in FIG. 5 will be described in detail. The rack 41 has a pillar 45 having a U-shaped cross section in front, rear, left and right.
The holes (not shown) for mounting the rack mount device 51 are formed at predetermined intervals in the vertical direction with the horizontal interval of the column 45 set to 19 inches. In many cases, the rack mount device 51 is mounted at an arbitrary position by using this hole.

When a rack mount device is mounted on a rack, as shown in FIG. 8 (a), a rail 43 is attached using a hole formed in the aforementioned column 45, and a rack mount device 52 is attached to the rail 43. When mounting directly,
In some cases, a rack mount device 52 having a relatively small width dimension is mounted on the rail 43 via the base 44.
As shown in FIG. 8B, a rack mount device 52 mounted on the rail 43 is attached to another rack mount device 51.
May be directly mounted. That is, there are cases where a plurality of rack mount devices are mounted one on top of the other.

As described above, in the rack mount apparatus, there is a case where a desktop type apparatus which is installed and used at a general office desk is mounted on the rack in addition to the apparatus dedicated to the rack mount as described above. Since the rack mount device dedicated to rack mounting does not regulate the mounting position on the rack, an air filter for preventing intrusion of dust is provided in advance at the position of the air inlet.

On the other hand, when a desktop device is used as a rack-mount device, the desktop device is installed on an office desk or the like, and therefore, is usually not equipped with an air filter for preventing intrusion of dust. In addition, the cooling air circulation takes various forms of circulation of the cooling air, such as one having the cooling air flowing in the left-right direction and one having the cooling air flowing in the front-back direction.

As described above, a rack-mounting device requires an air filter and a mounting mechanism for mounting on a rack, and is often expensive. Therefore, a desktop device is used as a rack-mounting device. Often used.

FIG. 9 shows a diagram of the prior art. In this figure, a rack-dedicated device that has cooling air flow in the left and right direction or a desktop device is used as a rack-mounted device in a rack that does not have ventilation holes on the side surface and that has ventilation holes on the rear surface, which is widely used in general. And rail 4
A case will be described in which another rack mount device 51 is directly mounted on the rack mount device 52 mounted on No. 3.

Referring to FIG.
The rack mount device 52 mounted via the air inlet is configured to take in cooling air from the right side and exhaust warm air from the left side. Further, the rack mount device 52
The rack mount device 51 which is directly mounted on the vehicle is formed such that cooling air is taken in from the left side and warm air is exhausted from the right side. In this case, since the rack 41 has no ventilation hole on the side surface, the rack mount device 51 draws in warm air from the rack mount device 52, and the rack mount device 52 draws in warm air from the rack mount device 51. That is, the warm air exhausted by the rack mount devices 51 and 52 circulates between the rack mount devices 51 and 52.

Referring to FIG.
The rack mount device 52 mounted via the air inlet is configured to take in cooling air from the right side and exhaust warm air from the left side. Further, the rack mount device 52
The rack mount device 51 which is directly mounted on the vehicle is formed so that cooling air is taken in from the right side and warm air is exhausted from the left side. In this case, since the rack 41 has no ventilation hole on the side surface, the rack mount device 51 takes in the warm air of the rack mount device 51 itself and the warm air of the rack mount device 52, and the rack mount device 52 uses the rack mount device 52 itself. And the warm air of the rack mount device 51 are sucked. That is, the warm air exhausted by the rack mount devices 51 and 52 circulates between the rack mount devices 51 and 52.

As described above, the warm air exhausted by the plurality of rack mount devices circulates between the plurality of rack mount devices, and the internal temperature of each rack mount device rises due to the heat generated by each rack mount device. May not work properly, or the system may go down. When a desktop device without an air filter is used as a rack mount device, an air filter is provided inside the rack mount device when necessary, depending on the mounting position on the rack and the use environment.

[0014]

As described above, the prior art has the following problems.

1) In a cooling structure of a rack mount device mounted on a rack having a cooling air flow in the left and right direction of the electronic device, warm air exhausted by the plurality of rack mount devices circulates between the plurality of rack mount devices. In addition, the cooling efficiency of each rack mount device is reduced. For this reason, the internal temperature of each rack mount device rises due to heat generated by each rack mount device.

2) When a desktop device without an air filter is mounted on a rack as a rack-mount device, dust enters the rack-mount device, which causes clogging of ventilation holes and reduces cooling efficiency. Let it.

3) For this reason, when a desktop device which is not equipped with a built-in air filter is used as a rack mount device, an air filter is provided inside the device. Loses versatility.

[0018]

In order to solve the above problems, the present invention takes the following measures.

A shielding member for preventing the circulation of air between the rack mount devices mounted on the upper and lower sides is provided externally to the rack mount device. An air filter is provided externally on the lateral surface of the rack mount device.

By taking the above measures, the air circulation between the rack mount devices mounted on the upper and lower sides is prevented by the shielding member, so that the heat treatment is performed by the rack mount device alone, thereby improving the cooling efficiency of the rack mount device. improves. In addition, when a rack mount device that does not have a built-in air filter is mounted on a rack, the air filter is easily attached externally, thereby preventing cooling holes from being clogged with dust and improving cooling efficiency.
