Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor-installed cabinet accommodating electronic devices, and more particularly, to an outdoor-installed cabinet accommodating a battery as an emergency power supply. 2. Description of the Related Art An outdoor installation type cabinet accommodating electronic devices has a hermetically sealed enclosure having a hermetically sealed structure for preventing obstacles caused by rainwater and dust. And an internal air-conditioning unit for efficiently discharging heat generated from electronic devices packed in a limited space inside the closed casing to the outside. In addition, this outdoor installation type cabinet contains a battery as a backup power supply in the event of a commercial power failure. [0003] A conventional outdoor installation type cabinet is composed of, for example, a closed casing and a non-closed casing. Various electronic devices, a power supply unit, a fan unit for stirring the internal atmosphere, and the like are accommodated in the closed housing. Above the ceiling of the closed casing, a heat radiating portion for radiating heat generated from electronic devices is provided. In addition, the non-sealed housing portion is a battery housing portion for housing a battery, and is provided with a ventilation window on a door to form a well-ventilated compartment. As described above, by making the battery housing section a section having good air permeability, even if a large amount of gas is generated when the battery is overcharged, an accident such as an explosion can be prevented. [0004] However, the outdoor-installed cabinet described above has a non-sealed housing part with good air permeability for accommodating a battery separately from the sealed housing part. There was a problem that it became complicated and cost increased. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and includes a battery housing sealed box housing a battery in a sealed housing housing equipments. An outdoor-installed cabinet characterized in that the inside of a battery-containing closed box is communicated with outside air. According to the present invention, the battery is housed in the battery housing airtight box and housed in the airtight housing. Therefore, a non-sealing housing part with good air permeability for housing the battery is provided as in the prior art. Elimination of the need simplifies the structure and reduces the cost. Further, although the battery housing closed box is housed in a closed housing,
Since the inside communicates with the outside air, gas generated from the stored battery is discharged to the outside, and there is no possibility that an accident such as an explosion may occur. Embodiments of the present invention will be described below in detail with reference to the drawings. FIGS. 1A and 1B are a schematic internal front view and a schematic internal side view of an outdoor installation type cabinet according to an embodiment of the present invention, respectively, with a door removed and a side wall removed. In the present embodiment, a plurality of receiving plates 2 are provided in a closed casing 1, and a power receiving / distributing unit 11 and a fan control unit 1 are provided as devices on the receiving plate 2.
2, optical splicing box 13, uninterruptible power supply 1
4. Closed box 15 for storing battery, information processing device A
16. An information processing device B17 is mounted. Note that reference numeral 18 denotes a fan unit, and 19 denotes a cable entry board. The fan unit 18 and the cable entry board 19 are mounted on the bottom plate 3. Reference numeral 4 denotes a heat radiator, and the heat radiator 4 is provided on the ceiling 5. In the above embodiment, the fan unit 1
Numeral 8 is controlled by the fan control unit 12 to stir the atmosphere inside the closed casing 1 and make the temperature distribution inside the closed casing 1 uniform. The heat generated from the devices is radiated by the radiator 4 to prevent the temperature inside the closed casing 1 from rising. Cable drop board 1
Numeral 9 draws a metal cable and an optical fiber cable (not shown) from the outside into the closed casing 1 and fixes them.
The power receiving / distributing unit 11 supplies commercial power supplied via the cable drop-in board 19 to devices and the like. The uninterruptible power supply 14 is provided with a battery-containing closed box 15 so that the system does not go down even if the commercial power supply fails.
This is for switching over to the battery stored in a short time and continuing the system operation. Also, the optical splicing box 13, the information processing device A16, and the information processing device B17 perform desired processing on the input signal to output an output signal. The present embodiment is different from the conventional example in that a battery housing closed box 15 housing a battery is housed in a closed housing 1, and as described later, a battery housing closed box 15 is provided. That is, the inside of 15 was communicated with the outside air. [0010] The battery housing closed box 15 is shown in FIG.
As shown in (a) to (c), a spacer 15b for sealing four batteries (not shown) is provided inside the lid 15a. Further, the battery housing closed box 15 is provided with connection ports 15c and 15d for connecting hoses. As shown in FIG. 1 (b), the battery housing closed box 15 is
The hoses 20a, 20b are placed on the receiving plate 2 inside, and connected to the connection ports 15c, 15d. The hose 20a extends upward in the closed casing 1 and penetrates through the ceiling 5, and the inside of the battery housing closed box 15 is communicated with the outside air by the hose 20a. Further, the hose 20b hangs downward in the sealed housing 1 and is provided for draining water. As described above, in the present embodiment, the battery housing closed box 15 housing the battery is housed in the closed housing 1, so that the conventional air-permeable non-battery box for housing the battery is used. There is no need to provide the closed casing part separately from the closed casing part, so that the structure is simplified and the cost is reduced. In addition, the battery housing closed box 15
Is connected to the outside air by the connected hose 18a, so even if gas is generated from the stored battery,
This gas is discharged to the outside, and there is no risk of an accident such as an explosion. The above embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention. As described above, according to the present invention, the structure is simplified, the cost is reduced, and even if gas is generated from the battery, there is no danger of an accident such as explosion. There is an excellent effect.
