Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage / cooling device for a heat-generating device capable of storing units in a plurality of upper and lower stages and efficiently cooling the heat generated from the stored units.

[0002]

[Prior art]

 For example, various storage devices for heat-generating devices have been developed and used, in which heat-generating components such as a transformer, an inverter, and a rectifier are put together as one unit, and the units are vertically stored in multiple stages.

In such a storage device, in order to efficiently dissipate the heat generated during the operation so that the required operation function can be normally exhibited, for example, as shown in FIG. It is known that a forced exhaust system is attached.

That is, this has an opening 100 A for taking in air from the outside on the front side of the housing 100 of the storage device, and each unit is provided with a breathable casing 101, and the rear surface of the casing 101. The fan 102 is attached to the air conditioner and the like, and the outside air forcibly taken in through the opening 100A is discharged from the exhaust part 100B on the rear side of the casing 100 to cool the air.

However, in such a forced exhaust type, as shown in the figure, there is a possibility that the air passing through the inside of the unit 101 may collide with the rear surface of the housing 100 and then turn around in the front side direction. there were. For this reason, it is not possible to cool it efficiently, which causes inconvenience.

Therefore, for example, as shown in FIG. 4, the air guide plate 103 is installed between the units 101 and between the unit and the housing 100 with an inclination so that the outside air is naturally supplied to the upper part of the housing 100. What has been configured to allow is being developed.

[0007]

[Problems to be solved by the device]

 By the way, with such a structure, the air flow is natural and there is no problem in that respect, but since the baffle plate must be installed at an angle, the installation work is troublesome. , It is difficult to take out the unit. In addition, when wiring between these units with a cord from the back side of the unit, the wiring work is difficult and poses a problem.

In view of the above-mentioned circumstances, the present invention is capable of performing efficient forced cooling, is easy to assemble and take out the units, and is easy to wire between the units. The objective is to provide a storage and cooling device for equipment at low cost.

[0009]

[Means for Solving the Problems]

 In other words, this invention is designed to cool a heat-generating device unit mounted on a rack mounted in multiple stages in the vertical direction, and to cool the heat-generating device unit, the heat-generating device is equipped with a fan for taking in cooling air from outside the front of the unit and discharging it from the rear of the unit. In the storage / cooling device, a shielding plate for preventing air that has passed through the upper and lower units from wrapping around to the front side after collision at the rear surface of the housing is located at a position connecting the rear surfaces of the upper and lower units. And is attached to the shelf or the housing in a direction perpendicular to or close to the floor surface of the housing.

[0010]

[Action]

 In this invention, the shielding plate is arranged so as to be continuous with the back surface of each unit, and it is possible to reliably prevent the air taken in from the front surface from going around to the front side even if it collides with the back surface of the housing. .

Further, in the present invention, since the shielding plate is arranged in the direction perpendicular to the floor surface of the housing or in a state close to this, it is possible to easily perform the mounting work and the unit removal work. .

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a storage cooling device for heat-generating equipment according to the present invention. In this storage cooling device, a shielding plate 2 is arranged so as to be connected to the back surfaces of upper and lower units 101 in a housing 1. . Reference numeral 3 in the drawing indicates a pair of left and right shelves that support each unit 101, and is formed in an L-shaped cross section.

The shielding plate 2 is screwed to the leg portion 1C of the housing 1 as shown in FIG. 2, and is formed of an iron plate or the like in this embodiment, but is made of an insulating metal or other material. May be formed with.

Further, a terminal block 5 for electrical connection with each unit 101 and mounting various necessary electronic components 4 is attached to the back surface of the shielding plate 2. The shield plate may be attached between the shelves 3.

Therefore, according to this embodiment, the outside air forcibly taken from the front opening 1A of the housing 1 by the fan 102 attached to the rear surface of each unit 101 is stored in each unit 101 inside the unit 101. Air can be efficiently cooled by passing through. Further, since the air exhausted from the rear surface of the unit is prevented from wrapping around to the front side by the shielding plate 2, it is reliably exhausted from the exhaust portion 100B at the inner portion of the housing 1.

[0016]

[Effect of device]

 As described above, according to the present invention, since the shielding plate is arranged so as to be continuously connected between the rear surfaces of the units or between the rear surface of the unit and the housing, the shielding plate is arranged from the front side. Even if the taken-in air collides on the back side, it can be surely prevented from turning to the front side, and efficient air cooling can be performed.

Moreover, in this invention, since the shielding plate is arranged in the direction perpendicular to the floor surface of the housing or in a state close to this, it is possible to easily perform the mounting work and the unit removal work. .

Further, according to the present invention, in the conventional forced exhaust type, a simple change in mounting the shield plate can be realized, that is, an efficient cooling mechanism can be realized at a low cost, so that a large practical effect is obtained. Can be expected.
