"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.

Fig. 1 is a schematic structural diagram for explaining an exemplary embodiment of a cabinet. Fig. 2 is a schematic diagram for explaining another state of the cabinet. Referring to fig. 1 and 2, the cabinet includes a cabinet body 10, a partition 20, two first fans 30, and two second fans 40.

Referring to fig. 2, the cabinet 10 is formed with an inner cavity extending along a height direction H, and the height direction H is perpendicular to the ground direction when the cabinet 10 is used. The cavity is used for mounting the active power filter 50. Referring to fig. 1, the cabinet 10 is further formed with two fan inlets 13 and two fan outlets 15 respectively communicating the inner cavity and the outside of the cabinet 10.

The partition 20 is disposed in the inner cavity, the partition 20 divides the inner cavity into a hot area space 17 and a cold area space 19 along the height direction H, and the hot area space 17 is located above the cold area space 19 when the cabinet 10 is in use. The heat dissipation inlet 52 and the fan inlet 13 of the active power filter 50 are located in the cold area space 19, and the heat dissipation outlet 54 and the fan outlet 15 of the active power filter 50 are located in the hot area space 17.

The first fan 30 is disposed at the fan inlet 13 and is capable of delivering air from outside the cabinet 10 to the cold zone space 19. The second fan 40 is disposed at the fan outlet 15 and is capable of delivering air from the hot zone space 17 to the outside of the cabinet 10.

Fig. 3 is a cross-sectional view of the enclosure of fig. 1 at a location III-III. Referring to fig. 3, the cabinet divides the interior of the cabinet 10 into a hot zone space 17 and a cold zone space 19 by a partition 20. Referring to the dotted arrows in fig. 3, the first fan 30 sucks cold air into the cold area space 19 through the fan inlet 13, the active power filter 50 sucks cold air in the cold area space 19 into the cooling path through the heat dissipation inlet 52, and discharges hot air into the hot area space 17 through the heat dissipation outlet 54, and the second fan 40 discharges hot air in the hot area space 17 out of the cabinet 10 through the fan outlet 15. The partition 20 can reduce the dead air path from the fan inlet 13 to the fan outlet 15 outside the active power filter 50, and prevent the air inside the cabinet 10 from circulating outside the active power filter 50, so that the cabinet can increase the amount of cold air passing through the active power filter 50, thereby improving the cooling effect of the active power filter 50.

Although the number of the first fan 30 and the fan inlet 13 and the number of the second fan 40 and the fan outlet 15 are two corresponding to each other in the exemplary embodiment, the number is not limited thereto, and in other exemplary embodiments, the number of the first fan 30, the number of the fan inlet 13, the number of the second fan 40 and the number of the fan outlet 15 may be set according to actual requirements, and may of course include only one.

In an exemplary embodiment, referring to fig. 1 and 2, the cabinet 10 is a rectangular parallelepiped, and the height direction H is parallel to one side of the cabinet 10. The cabinet 10 includes a pair of side panels 12, a door panel 14, and a bottom panel 16. The pair of side plates 12 are opposed to and parallel to the height direction H. The door panel 14 is arranged parallel to the height direction H and is rotatably arranged on one side panel 12.

When the first fan 30 and the second fan 40 are not activated, air within the cabinet 10 may pass through the gap to balance the pressure differential between the hot zone space 17 and the cold zone space 19 caused by the active power filter 50. And the reserved gap can reduce the requirement on the machining precision of the partition board 20 and the difficulty of installation.

In the exemplary embodiment, the cabinet further includes a temperature sensor disposed in the hot-zone space 17, wherein the temperature sensor is capable of sending a trigger signal for controlling the start of the first fan 30 and the second fan 40 when the temperature in the hot-zone space 17 reaches a preset temperature, and the trigger signal is sent to the control device for controlling the first fan 30 and the second fan 40, which may be the control device of the reactive power compensation and harmonic suppression equipment or a separate cooling control device.
