Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet for an electric apparatus which houses electronic and electric equipment used for a data communication network such as a LAN and a WAN, and other electronic and electric equipment. The present invention relates to a cabinet for electric equipment in which heat generated by electric equipment is improved.

[0002]

2. Description of the Related Art Conventionally, a cabinet for an electric device has a vertically long box-shaped cabinet body for accommodating electronic and electric equipment, in which at least one of a bottom surface, a side surface, and a back surface can be sucked, and heat generated by the electronic and electric device is generated. In order to dissipate, an exhaust fan is attached to one or more exhaust holes provided on the upper surface.

[0003]

However, when a conventional cabinet for an electric device is installed, a large number of cabinets are often arranged side by side in order to make the installation space compact. Due to the reduction, there is a problem that it is difficult to sufficiently dissipate heat only by exhausting air by the exhaust fans provided on the respective upper surfaces.

Accordingly, an object of the present invention is to provide a cabinet for an electric device capable of sufficiently releasing heat.

[0005]

In order to solve the above-mentioned problems, a cabinet for an electric device according to the present invention has an opening extending over at least one side of a vertical box-shaped cabinet main body capable of taking air from at least one of the whole surface. A relatively flat box shape having substantially the same outer shape as one side surface of the cabinet body, and an exhaust port provided in at least one of an upper surface, a front surface, and a rear surface, and a plurality of surfaces provided on one surface. The fan ducts each having an exhaust fan attached to the exhaust hole are air-tightly attached so that one side faces one side of the cabinet body and covers the opening on one side.

In order to facilitate inspection, maintenance, repair, replacement, and the like, it is preferable that the exhaust fan be divided into a required number at a time and be detachably attached to the fan duct.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1, 2, 3, 4,
FIGS. 5 and 6 are a front view, a right side view, and a left side view showing an example of an embodiment of an electric device cabinet according to the present invention.
FIG. 6 is a rear view, a plan view, and a view taken along line VI-VI in FIG. 1. In the figure, reference numeral 1 denotes a vertically long box-shaped metal cabinet main body for housing electronic / electrical equipment (not shown), and an opening 3 for intake with an expanded metal 2 is provided in a lower portion of the back thereof. In addition, a vertically long rectangular opening 4 for dissipating heat generated by electronic / electrical equipment is provided on almost the entire left side surface.

On the left side of the cabinet body 1, a fan duct 5 having a relatively flat box shape and substantially the same outer shape is provided.
Are attached by screws or the like. The fan duct 5 is for discharging the air inside the cabinet body 1 heated by heat generated by the electronic / electrical device upward, and as shown in FIG. A rectangular exhaust port 7 attached to the inside is provided over almost the entire surface, and a right side surface, that is, a surface opposed to the left side surface of the cabinet body 1 (the left side surface in FIG. 7) is provided on the cabinet body 1. Opening 4
A plurality of (e.g., three in FIG. 7) openings 8 of a horizontally-long rectangular shape are provided at appropriate intervals in the up-down direction, and the upper and lower opening edges of each opening 8 are provided with a fan described later. A guide flange 9 for guiding the mounting plate in and out is projected inward. On the back surface of the fan duct 5, vertically long rectangular windows 10 are provided corresponding to the respective openings 8, and these windows 10 are provided so as to be airtightly closed by a lid 11.

[0009] Each opening 8 of the fan duct 5 is
They are provided so as to be airtightly closed by a horizontally long rectangular fan mounting plate 12 having substantially the same outer shape as those. The fan mounting plate 12 is inserted into and removed from the fan duct 5 through the window 10 and shown in FIGS.
As shown in FIG. 0, a flange 13 is provided on the upper and lower edges of the fan duct 5 so as to be able to slide on the guide flange 9 of the opening 8, and the fan mounting plate 12 is locked in the opening 8. Therefore, one end of the fan mounting plate 12 at the flange 13 (the left end in FIG. 9)
On the side, a notch 14 that can be engaged with the side edge of the opening 8 of the fan duct 5 is provided, and a pull 15 for inserting and removing the fan mounting plate 12 is connected to the other end (in FIG. 9). Is bent at the right end) side. Furthermore,
A plurality (four in FIG. 8) of exhaust holes 16 are provided at the fan mounting plate 12 at appropriate intervals.
As shown in FIG. 7, each exhaust hole 16 has an exhaust fan 17.
Are attached. As described above, the fan mounting plate 12 is inserted into the fan duct 5 from the window 10 while sliding the flange 13 against the guide flange 9 of the fan duct 15, and the notch 14 is formed on the side of the opening 8. After being locked to the rim, it is attached to the fan duct 5 by fasteners (not shown) such as bolts.

In FIG. 1, reference numeral 18 denotes a door of the cabinet body 1, and in FIGS. 2 and 3, reference numeral 19 denotes a connection through which a connector (not shown) such as a bolt for connecting the adjacent cabinet body 1 with a fan duct is inserted. In FIG. 7, reference numeral 20 denotes a fan duct 5 for connecting the cabinet
Mounting holes for mounting to
Is a magnet catch as a temporary fixing means when the fan mounting plate 12 is mounted on the fan duct 5.

To dissipate the heat generated by the electronic / electrical equipment in the cabinet for an electric device having the above-described structure, each exhaust fan 17 attached to the fan duct 5 is operated, and the opening 3 in the lower rear part of the cabinet body 1 is opened. And draws warm air in the cabinet body 1 into the fan duct 5 and discharges the air upward through the exhaust port 7. In order to perform maintenance, repair, replacement, etc. of the exhaust fan 17, the lid 11
Is removed, and the fan mounting plate 12 is pulled out of the window 10 to perform the operation.

In the above-described embodiment, the case where the fan duct 5 is attached to the left side surface of the cabinet body 1 has been described. However, the present invention is not limited to this. The fan duct 5 may be attached to one of the right side surface, the front surface, or the back surface of the cabinet body provided with the opening. Further, the exhaust port 7 of the fan duct 5 is not limited to the case where the exhaust port is provided on the upper surface. Metal may be applied to the inside of the fan duct 5.

[0013]

As described above, according to the cabinet for an electric device of the present invention, almost the entire side surface having a larger area than that of the conventional upper surface can be used for exhaust, so that a sufficient amount of air can be exhausted. Heat can be dissipated.
