Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an air-cooled DCDC cabinet, which enables maintenance personnel to perform maintenance on fan components from the main door.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an air-cooled DCDC cabinet, comprising a cabinet and a fan assembly; the cabinet has an air inlet on the front door panel, and the inner cavity of the cabinet is provided with a first partition plate, the first partition plate divides the inner cavity of the cabinet into a DC module installation area and other device installation areas located below the DC module installation area, and air circulates between the DC module installation area and the other device installation areas; the fan assembly is arranged at the top position of the back of the cabinet.

[0005] Furthermore, an air guide plate is provided in the DC module installation area, and the air guide plate is inclined toward the air inlet end of the fan assembly.

[0006] Furthermore, a second partition plate is provided in the inner cavity of the cabinet, and the second partition plate separates the remaining device installation area into an external input area and an external output area, and air circulates between the external input area and the external output area.

[0007] Furthermore, the external input area is located above the external output area.

[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0017] At present, the DCDC cabinet of the integrated photovoltaic storage charging and inspection smart charging station is usually designed with a front door and a back door. The front door is designed to facilitate the maintenance of components such as DC modules, and the back door is designed to facilitate the maintenance of components such as fans installed on the back of the DCDC cabinet. However, when the DCDC cabinet is installed in a limited space such as a container, the back door of the DCDC cabinet usually cannot be opened normally, and the entire DCDC cabinet needs to be disassembled for maintenance, which increases the difficulty of maintenance.

[0018] Based on this, the present application provides an air-cooled DCDC cabinet, which can solve the problem that the rear door of the DCDC cabinet cannot be opened normally, resulting in difficulty in repairing the fan assembly.

[0019] Please refer to Figures 1 to 3 As shown, the utility model is an air-cooled DCDC cabinet, comprising a cabinet 1 and a fan assembly 2; the cabinet 1 has an air inlet on the front door panel, and a first partition plate 11 is arranged in the inner cavity of the cabinet 1, the first partition plate 11 divides the inner cavity of the cabinet 1 into a DC module installation area 12 and a remaining device installation area 13 located below the DC module installation area 12, and air circulates between the DC module installation area 12 and the remaining device installation area 13; the fan assembly 2 is arranged at the top position of the back of the cabinet 1.

[0020] Working principle: A first interlayer board 11 is arranged in the inner cavity of the cabinet 1, so that the inner cavity of the cabinet 1 is divided into a DC module installation area 12 for installing a DC module and a remaining device installation area 13 for installing devices such as a control panel group, circuit breakers, copper bars, relays, fuses, etc., thereby ensuring that the circuit in the DC module installation area 12 is neat and the equipment is arranged. Since the fan assembly 2 is arranged at the top position of the back of the cabinet 1, that is, the fan assembly 2 is only blocked by a few DC modules, the hot air discharged by the DC module can be directly discharged from the inner cavity of the cabinet 1 by the fan assembly 2, thereby ensuring the ambient temperature in the DC module installation area 12. When inspecting the fan assembly 2, it is only necessary to remove the DC module blocked in front of the fan assembly 2 to expose the fan assembly 2 to the maintenance personnel. At the same time, the arrangement of the first interlayer board 11 can reduce the influence of the hot air discharged by the DC module on the devices in the remaining device installation area 13, and under the action of the fan assembly 2 exhausting air, the hot air in the remaining device installation area 13 can also be discharged to the outside of the cabinet 1 by the fan assembly 2.

[0021] Please refer to Figure 1 As shown, further, an air guide plate 121 is provided in the DC module installation area 12 , and the air guide plate 121 is inclined toward the air inlet end of the fan assembly 2 .

[0022] It can be seen from the above description that adding the air guide plate 121 helps to guide the hot air to be discharged toward the fan assembly 2 .

[0023] Please refer to Figure 3 As shown, further, a second partition plate 14 is provided in the inner cavity of the cabinet 1, and the second partition plate 14 divides the remaining device installation area 13 into an external input area 131 and an external output area 132, and air circulates between the external input area 131 and the external output area 132.

[0024] From the above description, it can be seen that the second partition plate 14 is used to further divide the remaining device installation area 13, so that the devices used for input and the devices used for external output are arranged separately, further optimizing the arrangement of related devices in the cabinet 1 to facilitate the maintenance personnel's work.

[0025] In one embodiment, the external input area 131 is configured with a control panel group, a circuit breaker and an input cable, and the external output area 132 is configured with a copper bus, a relay, a fuse and an output cable.

[0026] Please refer to Figure 3 As shown, further, the external input area 131 is located above the external output area 132 .

[0027] Please refer to Figures 1 to 3 As shown, further, the bottom of the cabinet 1 is provided with a lifting support foot 15, and the bottom of the cabinet 1 is provided with a threading hole (not shown in the figure).

[0028] From the above description, it can be seen that the cabinet 1 can be raised by raising the support feet 15 so that there is a cable entry space under the cabinet 1. The cable passes through the bottom of the cabinet 1 through the threading hole and enters the inner cavity of the cabinet 1, so as to facilitate the connection of the cable with the corresponding device.

[0029] In an optional embodiment, a threading hole (not shown) is provided at the bottom of the cabinet 1 near the front door of the cabinet 1. The threading hole near the front door of the cabinet 1 can facilitate cable routing and reduce the number of cable bends.
