Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to an uninterruptible power supply device that supplies power to equipment such as computers that cannot tolerate instantaneous power outages.

[Prior art and its problems]

The uninterruptible power supply is mainly composed of a semiconductor conversion device and a battery, but it is designed to be as reliable as possible.
It is also desirable that the device be compact and easy to assemble and maintain.

As shown in FIGS. 4 and 5, the conventional uninterruptible power supply system stores a storage battery 5 in the lower part of a box body 4 in which a top cover 1 and a side cover 2 are detachably attached using magnets 3. A semiconductor converter 6, a circuit breaker 7, and a capacitor unit 8 are installed on the top of the box, and an intake port 9 and an exhaust port 1 are installed on the back of the box.
0 is set. Wheels 41 are attached to the lower end of the box 4 to make it movable. A wind tunnel 11 is attached to the semiconductor conversion device 6 to collect the wind that cools the fins of the cooling body of the semiconductor element and guide it to the exhaust port 10, and a fan 12 is built in the wind tunnel.

In the above structure, the top cover and side covers are removed to attach parts, so the structure is complex and weak, and if the top cover is lifted carelessly during transportation, it may fall and be damaged, and the intake air The drawback was that because the mouths were close together, the exhaust gas was partially sucked in, reducing cooling performance and adversely affecting internal electronic components.

[Purpose of invention]

The present invention eliminates the above-mentioned drawbacks, and provides an uninterruptible power supply that simplifies the box structure, makes the box strong, makes assembly of parts easy, maintenance and inspection, and improves the cooling effect of installed equipment. The purpose is to provide.

[Key points of the idea]

In this invention, only the side cover on the side with the widest opening is removable, and the built-in equipment is arranged flat so that it can be easily installed and removed from the opening.In addition, the intake and exhaust ports are located above and below the rear panel. The space between the ends is widened to prevent exhaust air from being re-inhaled, and to allow internal cooling air to flow effectively.

[Example of idea]

1 to 3 show an uninterruptible power supply according to an embodiment of the present invention, and the same components as in FIGS. 4 and 5 are denoted by the same reference numerals. The opening of the box body 4, which is open only on one side, is covered with a side cover 2 which is detachable using a fastener 13, and a storage battery 5 is mounted on the lower floor inside the box body, and a semiconductor conversion device 6 and a circuit are mounted on the top of the storage battery 5. The circuit breaker 7 and the capacitor unit 8 are arranged and attached on a plane when viewed from the opening. Wheels 41 are attached to the box body 4, and an intake port 9 is provided at the lower end of the back, and an exhaust port 1 is provided at the upper end.
0 is set. As shown in FIG. 3, the semiconductor conversion device 6 is composed of a semiconductor element 61, a cooling body 62, and printed boards 63, 64, and the cooling body 62 is provided with fins that guide cooling air in a horizontal direction. The intake end 62a of the cooling body faces the inside of the box front plate, and the exhaust end 62b is exposed to the exhaust port 10 through the wind tunnel 14. Fan 1 in wind tunnel 14
2 is built-in.

Further, the cooling body 62 is provided with a cover that covers the fins, and the cover and the fins form a wind tunnel. Exhaust end 6 of this wind tunnel
The 2b side is installed so as to be in contact with the wind tunnel 14, and the cooling air taken in from the intake end 62a side of the cooling body 62 flows horizontally along the fins through the wind tunnel formed by the fins and the cover, and is exhausted. It passes through the wind tunnel 14 from the end 62b side and is discharged from the exhaust port 10.

In this configuration, when the fan 12 is operated, the cooling air sucked in from the intake port 9 flows horizontally along the fins of the cooling body 62, as shown by the arrow in FIG. 2, and is discharged from the exhaust port 10. , the semiconductor converter and the capacitor unit are effectively cooled.

[Effect of idea]

According to the present invention, components can be easily attached through the opening in a box having an open end on only one side, and the intake and exhaust ports are provided on the same back panel with as much space between them as possible. In addition, an air tunnel is formed by the cover that covers the fins, which effectively circulates cooling air inside and suppresses temperature increases, thereby improving the reliability, assembly and maintainability of the device.
