The cabinet body is composed of a main cabinet 1, a first side cabinet 2 arranged on the left side of the main cabinet 1 and a second side cabinet 3 arranged on the right side of the main cabinet 1. The main cabinet 1 includes a main cabinet top plate 11, a main cabinet bottom plate (not shown), a main cabinet front side plate 12, and a main cabinet rear side plate (not shown), and both left and right sides of the main cabinet 1 are designed to be opened to be in gas communication with the first and second side cabinets 2 and 3, so that the three surround a heat dissipation space. Wherein at least one air inlet 14 is provided in the front side panel 12 of the main cabinet as shown. Preferably, a fan may be disposed within each air inlet 14 to promote the flow of ambient air into the main cabinet 1.
Fig. 3 is a perspective view of the first side cabinet 2 or the second side cabinet 3. The first side cabinet 2 and the second side cabinet 3 are herein of similar or identical configuration, with the difference that when the structure shown in fig. 3 is used as the first side cabinet 2, its open side will be located on the right and it will be arranged on the left side of the main cabinet 1, whereas when the structure is used as the second side cabinet 3, its open side will be located on the left and it will be arranged on the right side of the main cabinet 1.

In this embodiment, air flows into the main cabinet 1 from the air inlet 14 of the main cabinet front side panel 12, then flows into the second side cabinet 3 and exits the cabinet via the air outlet 34 on the second top panel 31 of the second side cabinet 3.
In addition, the flowing direction of the air in the cabinet body is schematically shown in fig. 5, namely, the air flows in from the front side plate of the main cabinet and flows out from the air outlet of the second side cabinet. Although not shown, one skilled in the art can infer from embodiments of the cabinet having only the second side cabinet the flow of gas within the cabinet when having only the first side cabinet or both the first side cabinet and the second side cabinet.
The user can choose to adopt the cabinet body with one side cabinet or two side cabinets according to factors such as the size of the field, the required air exhaust amount or the air exhaust rate. Wherein the air exhausting performance of the cabinet body in the second embodiment and the third embodiment is similar, and the user can select to use the cabinet body according to the expected air exhausting position.

Preferably, the first power supply plate 24 may be fixedly installed on the first left side plate or the first bottom plate, and the second power supply plate 35 may be fixedly installed on the second right side plate 33 or the second bottom plate. The first power strip 24 and the second power strip 35 are shown in phantom in fig. 2-4.
A specific implementation of the above described airtight connection may for example be a screw thread connection of the first side cabinet 2 and/or the second side cabinet 3 to the main cabinet 1, wherein a sealing gasket is provided between the first side cabinet 2 and/or the second side cabinet 3 and the main cabinet 1. Of course, the corresponding side panels of the first side cabinet 2 and/or the second side cabinet 3 may also be welded directly to the corresponding side panels of the main cabinet 1.
It should be clear that, in the present technical solution, the airtight connection between the first side cabinet 2 and the second side cabinet 3 and the main cabinet is not necessarily limited, for example, the air inlet 14 is used as the main air inlet channel, and it is not excluded that a small amount of air flows between the first side cabinet 2 and the second side cabinet 3 connected to the main cabinet 1, as long as the side cabinet and the main cabinet 1 are integrally combined to form a relatively determined heat dissipation space.
Although the main cabinet 1, the first side cabinet 2 and the second side cabinet 3 are described as three separate parts, it should be understood by those skilled in the art that the first side cabinet 2 and the main cabinet 1 may be a single part in the second embodiment based on the above-described connection manner of the first side cabinet 2 and the main cabinet 1 and the connection manner of the second side cabinet 3 and the main cabinet; in the third embodiment, the second side cabinet 3 can also be a single piece with the main cabinet 1; in the first embodiment, the first side cabinet 2, the second side cabinet 3 and the main cabinet 1 can be a single piece.
In addition, the number of the exhaust ports and the air inlets is not limited herein, and can be set by those skilled in the art according to the requirement of exhaust.
Also provided is an uninterruptible power supply comprising the aforementioned cabinet, and further comprising a number of electrical devices arranged within the main cabinet 1.
As will be appreciated by those skilled in the art, the prior art uninterruptible power supply cabinet comprises substantially only the main cabinet 1 described above. When the exhaust port is provided on the rear side plate of the main cabinet as described in the background art, dust is easily accumulated on the rear side plate of the main cabinet, the accumulated dust easily enters the main cabinet 1, and the dust is not easily cleaned and has a potential safety hazard. In this context, the air outlet is not opened on the main cabinet 1 (e.g., the main cabinet ceiling 11), but is located at a position substantially obliquely above the main cabinet 1, so that dust does not directly accumulate in the main cabinet 1. In addition, if the exhaust fan is arranged on the exhaust port, the dust is more difficult to accumulate and even can not enter the cabinet body through further improving the air circulation speed in the cabinet body. In addition, as shown in fig. 3, a baffle may be further provided at the open right side of the first side cabinet 2 and the open left side of the second side cabinet 3 to further block dust or foreign substances that may enter the first side cabinet 2 and the second side cabinet 3 through the exhaust port from further entering the main cabinet, and the shape and size of the baffle are not limited herein, but it cannot cut off the air communication of the first side cabinet 2 or the second side cabinet 3 with the main cabinet 1.
