JPH10210610A - Component configuration structure body in control panel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a structure body for effectively installing a plurality of apparatuses in a control panel without deteriorating cooling effect. SOLUTION: An apparatus 1 such as an inverter provided with a fan 2 is fixed on a mounting plate 51. A plurality of the plates 51 are fixed in the vertical direction so that the plates are arranged in a plane, when viewed from the front. The fans 2 are installed so that the heat generated in a panel flows in the right and the left directions. A diaphragm 4 is installed on the mounting plate 51, in the vertical direction, in order that discharging heat generated in the mounting plate part on which the apparatus 1 is fixed is not affected by each of the mounting plate part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component arrangement structure for accommodating a device such as an inverter having a fan in a panel such as a switchboard or a control panel.

[0002]

2. Description of the Related Art FIG. 3 shows an arrangement of parts for accommodating an inverter for controlling a motor and equipment including a plurality of electric parts in a control panel or the like. That is, the mounting plate 5 provided with the cooling fan 2 and the device 1 such as the inverter is arranged vertically. Since the semiconductor elements constituting the inverter generate a particularly large amount of heat, each inverter is provided with a cooling fan 2 for sucking air from below to cool the semiconductor elements and raise the air whose temperature has risen to the upper part. An exhaust cooling method is generally employed.

[0003]

However, in such a configuration, when a plurality of inverters are arranged in a panel, the inverter arranged in the upper stage sucks air discharged from the lower inverter and cools the air. In order to prevent the efficiency from lowering, it is necessary to arrange the vertical and vertical distances sufficiently large. Further, as shown in FIG. 4, a structure in which the devices are arranged like a platform is also adopted, but in this case, it is necessary to increase the depth dimension of the control panel and the like. An object of the present invention is to solve such a problem and to provide a structure for efficiently mounting a plurality of devices in a panel without impairing the cooling effect.

[0004]

In general, heat generated in a semiconductor element constituting an inverter is radiated through a cooling fan, and a cooling fan is provided as a means for efficiently radiating heat. In order to solve the above-mentioned problem, according to the present invention, as shown in FIG.
In addition, the equipment is installed horizontally with the air intake and exhaust parts on the left and right. Further, by providing the partition plate 4 on the back surface of the mounting plate 51, the air discharged from the lower device is not taken in by the upper device, and the cooling effect is not affected.

According to the structure of the present invention, in a mounting structure in which at least two or more devices are mounted,
By arranging the devices sideways, the air whose temperature has increased after cooling each device does not affect the cooling of the device immediately above. FIG. 1 shows a case in which the mounting plate 51 and the partition plate 4 form an intake and exhaust air tunnel on the back side of the mounting plate 51, and the air is sucked from the right side when viewed from the front side of the panel and exhausted to the left side. I have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. FIG. 1 shows a front view of the control panel, in which a door is omitted so that the inside can be seen. 1 and 2, a mounting plate 51 is mounted in a box of a control panel, and devices 1 such as an inverter and other electric parts 3 are mounted on the mounting plate 51. A partition is provided on the back side of the mounting plate 51. The plate 4 is mounted, and a plurality of mounting plates 51 are arranged. The arrows in FIG. 1 indicate the flow of air for cooling devices such as inverters.
Air is sucked in from below the right side by the cooling fan 2 of the inverter to take away heat generated inside the inverter, and as a result, the air with the increased temperature is discharged to the upper left side. The upper inverter is similarly cooled, but the cooling effect is not affected by attaching the partition plate 4 to the back side of the attachment plate 51.

[0007]

As described above, according to the present invention, when a plurality of devices are mounted, each device is mounted laterally on the mounting plate, and the partition plate is provided on the back side of the mounting plate. In addition, the vertical distance between the mounting plates can be reduced, a plurality of mounting plates can be arranged on the same surface, and the size of the control panel can be minimized without impairing the cooling effect of each device.
