Description

Inside the cabinet, various electronic components are installed to ensure normal operation of the entire system. When these electronic components are working, a large amount of heat will be generated once power is turned on. In particular, for power supply units (PSU), due to their relatively small size and frequent operation in a closed environment, they will generate a large amount of heat themselves.

DETAILED DESCRIPTION

[0044] In view of the deficiencies in the prior art, the present inventors have long studied and practiced to come up with the technical solution of the present application. The technical solution, its implementation process and principles will be further explained as follows.

[0045] Please refer to Figures 1-3 The present application provides a multifunctional heat dissipation power cabinet, which comprises a cabinet body, a power supply structure, a water-cooled heat dissipation structure and an air-cooled heat dissipation structure, wherein the power supply structure, the water-cooled heat dissipation structure and the air-cooled heat dissipation structure are encapsulated in an assembly cavity formed by the cabinet body.

[0046] In the middle part of the cabinet body, a partition plate 34 is arranged to divide the assembly cavity into an upper assembly cavity and a lower assembly cavity, thereby providing a dedicated installation area for different structures.

[0047] The power supply structure comprises a power supply module and a control module, wherein the control module is arranged in the upper assembly cavity, and the power supply module is arranged in the lower assembly cavity.

[0048] Firstly, the power supply module (PSU power supply) is relatively heavy and is generally placed at the bottom of the cabinet. Secondly, considering that the control circuit needs to be wired from the outside of the cabinet, placing the control module at the top will make it more convenient for wiring work. In addition, the power supply module (PSU power supply) itself generates a lot of heat. If it is placed at the top of the cabinet, the distance from the cable leading out of the cabinet to the control circuit will be affected by the heat, which is not conducive to the long-term use and maintenance of the cable.

[0049] The upper assembly cavity is further subdivided into three control cavities: a first control cavity, a second control cavity, and a third control cavity. The control module includes two main parts, namely a first power control module and a second power control module. The first power control module is installed in the first control cavity, and the second power control module is placed in the second control cavity. The first power control module and the second power control module are strong current parts. These two power control modules are electrically connected to the corresponding power supply modules, ensuring stable power supply and precise control. In the third control cavity, a circuit breaker device and a weak current part are arranged, which are closely connected with the power supply module and the control module, providing additional safety protection for the entire power cabinet.

[0050] The lower assembly cavity comprises a first power cavity and a second power cavity, and the power supply module comprises a first height power supply module and a second height power supply module, wherein the first height power supply module is arranged in the first power cavity, and the second height power supply module is arranged in the second power cavity.

[0051] The lower assembly cavity is subdivided into two independent power cavities: a first power cavity and a second power cavity. The power supply module includes two height power supply modules, with the first height power supply module being arranged in the first power cavity and the second height power supply module being placed in the second power cavity. This design allows flexible layout of power supplies of different heights, facilitating maintenance and upgrading.

[0052] In order to further improve safety, the first control cavity and the second control cavity are effectively isolated by left and right partitions 33. At the same time, the third control cavity is provided with an isolation cavity between the first control cavity and the second control cavity, which is formed by the first mounting plate 31, the second mounting plate 32, and the cabinet door sealing plate, ensuring the safe operation of the control module. Through holes are specially provided on the first mounting plate 31 and the second mounting plate 32 to meet the needs of heat dissipation and wiring.

[0053] A handle lamp mounting plate 35 is provided between the first control cavity and the second control cavity to facilitate operation. In addition, a plastic shell mounting plate 36 is mounted on the first mounting plate 31 in the first control cavity and the second control cavity for high-voltage wiring. In the third control cavity, a UPS circuit breaker operation panel 37, a grounding copper bar mounting bracket 38, a wiring cable fixing bracket 39, and a PCBA mounting plate 40 are mounted on the second mounting plate 32.

[0054] As shown in Figure 17 , a circuit breaking device is provided in the third control cavity. The circuit breaking device includes a circuit breaker mounting plate, a UPS circuit breaker operation panel 37, and a UPS operation panel 231. The UPS operation panel 231 is provided on the upper left door 23 at the back of the cabinet, and the circuit breaker mounting plate is installed on the second mounting plate 32. The UPS circuit breaker operation panel 37 is provided on the circuit breaker mounting plate.

[0055] The cabinet body of the power supply cabinet includes a cabinet frame 100, a sealing plate assembly, and a cabinet door assembly. These sealing plate assemblies and cabinet door assemblies are mounted on the cabinet frame 100 to ensure the stability and durability of the power supply cabinet. As shown in Figure 4 , the cabinet frame 100 is composed of multiple columns that are fixed together by plugs to form a solid frame structure, providing a solid foundation for the power supply cabinet.

[0056] The sealing plate assembly includes a top plate 27, a bottom plate 28, a water inlet and outlet sealing plate 29, and multiple sealing plates 20. As shown in Figure 5 , the sealing plates 20 can be provided in two or four, mounted on both sides of the cabinet frame 100. The sealing plates 20 are provided with reinforcing ribs 201, which not only enhance the structural strength of the cabinet body, but also improve the overall stability of the power supply cabinet. As shown in Figure 6 , the top plate 27 is provided with various wiring cover plates, including network and DB25 wiring cover plates 271, DC wiring cover plates 272, connector cover plates 273, UPS wiring cover plates 274, RF wiring cover plates 275, first voltage cover plates 276, and second voltage cover plates 277. Among them, the first voltage is set to 480V, and the second voltage is set to 208V, which meets the different voltage requirements.

[0057] As shown in Figure 7 , the bottom plate 28 is provided with a bottom plate reinforcing rib 281, a first cover plate 282, and a second cover plate 283. The first cover plate 282 and the second cover plate 283 are designed as reserved upper and lower wiring cover plates. The setting of these cover plates is based on the specific situation of the site. Whether the top or bottom cover plate is selected, the main purpose is to ensure that the cabinet body can maintain a closed state when not in use, thereby protecting the internal equipment from the external environment. As shown in Figure 8As shown, the water inlet and outlet sealing plate 29 is provided with water inlet and outlet 291. These inlets and outlets enable the water-cooled heat dissipation structure to be connected with the external water pump, thereby effectively leading out the heat generated by the power module.

[0058] As shown in Figure 9 - Figure 14 As shown, the cabinet door assembly includes a plurality of door panels, including the first control module packaging door (cabinet front upper left door 21, cabinet front upper right door 22), cabinet rear upper left door 23, cabinet rear upper right door 24, power module packaging door (cabinet rear lower left door 25, cabinet rear lower right door 26). These door panels not only protect the internal components, but also provide convenience for the operation and maintenance of the power cabinet.

[0059] The cabinet front upper left door 21 includes a busbar seat A plate 210, an empty door 211, a first grounding screw 212, a first hinge 213, a first limit pin support 214, a first sealing strip 215, and a first pull rod assembly 216.

[0060] The cabinet rear upper left door 23 includes a UPS operation panel 231, a reinforcing rib 232, a sealing strip 233, and a grounding screw 234. The arrangement of these components not only enhances the structural strength of the door panel, but also improves the safety of operation. The cabinet rear lower left door 25 includes ventilation gaps 251 and a handle 252. The cabinet rear lower left door 25 and the cabinet rear lower right door 26 are both provided with ventilation gaps 251, and the design of these ventilation gaps enables the power cabinet to effectively circulate air, thereby improving the heat dissipation efficiency.

[0061] The cabinet front upper left door 21 and the cabinet front upper right door 22 both have blank doors for mounting the busbar seat A plate and the busbar seat B plate, respectively. The water inlet and outlet sealing plate 29 is provided with water inlet and outlet 291, which enables the water-cooled heat dissipation structure to be connected with the external water pump, thereby effectively leading out the heat generated by the power module.

[0062] As shown in Figures 15-17 As shown, the first power cavity includes a plurality of power support plates 41, which are fixed to the cabinet frame 100. Between every two power support plates 41, a power gap sealing plate 42 is provided, which is fixed to the cabinet frame 100, helping to maintain the stability and safety of the power module. The two opposite power support plates 41 are connected with the first drip tray 45, forming a U-shaped structure for receiving the liquid leakage of the power module.

[0063] The second power supply compartment includes multiple PSU layer spacers 43, which are fixed to the cabinet frame 100. Each PSU layer spacer 43 is connected to a PSU cable fixing bracket 44 for easy wiring. Each PSU layer spacer 43 is connected to a second drip tray 46 for catching leaks from the power supply.

[0064] like Figures 18-19 As shown, both the first drip tray 45 and the second drip tray 46 are provided with through holes, which help to drain the leakage generated by the power supply. There is an inclined angle between the power supply support plate 41 and the first drip tray 45, which allows for better drainage of the leakage. Similarly, there is also an inclined angle between the PSU layer spacer plate 43 and the second drip tray 46, which also allows for better drainage of the leakage. Water inlet pipes are sequentially connected to the through holes of multiple drip trays, guiding the leakage from the drip trays into the water channel tray 50.

[0065] like Figure 20 As shown, the water-cooled heat dissipation structure includes a water channel tray 50 and a water channel support 51, with the support 51 supporting the tray 50. The water channel tray 50 is equipped with a water supply structure 53 and a water outlet structure 52. The water supply structure includes multiple first water channel manifolds, and the water outlet structure includes multiple second water channel manifolds. The first water channel manifolds are connected to the water inlet plug on the power supply, and the second water channel manifolds are connected to the water outlet plug on the power supply. The water supply structure 53 and the water outlet structure 52 are also connected to an external water pump via water inlet / outlet 291 on the water inlet / outlet sealing plate 29. The water supply structure also includes a first control valve 57. The water outlet structure also includes a second control valve for controlling the water flow rate.

[0066] One end of the conveying structure (water pipe) connects to the first drip tray 45 and the second drip tray 46 to collect leaked liquid, while the other end conveys the leaked liquid to the water path tray 50 via the tray quick connector 54. The tray quick connector and the connectors installed on the first drip tray 45 and the second drip tray 46 are connected via the water pipe. A leak detector 55 is installed on the water path tray 50. When the leak detector 55 detects a leak, it triggers and sends a leak signal. The leak signal is output to an alarm device outside the cabinet via the signal connector 56, ensuring timely alarm activation in case of power leakage, thereby guaranteeing the safe operation of the system.

[0067] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
