Description

Technical Field

[0001] This application relates to power backup equipment, and more specifically, to an uninterruptible power supply cabinet. Background Technology

[0002] As uninterruptible power supplies (UPS) power density increases, integration competition intensifies, and cost requirements rise. For example, UPS cabinets with top-mounted airflow and top-mounted cabling often require additional cabling side cabinets and top-mounted fan assemblies. However, achieving top-mounted cabling and top-mounted airflow within a single cabinet makes fan maintenance very difficult. Figure 1 As shown, if the uninterruptible power supply cabinet 1 uses a single cabinet for both top cable entry and top air exit, then the top cable entry hole 3 will completely block the space for maintaining the top air exit fan 2. The cable needs to be removed to maintain the top air exit fan 2, making online maintenance impossible. Figure 2 As shown, adding an incoming cable cabinet 4 to the uninterruptible power supply cabinet 1', with cables entering through the top cable inlet 3 on the top of the cabinet 4, can solve the problems of top airflow and top cable entry. However, this increases the floor space and cost. Furthermore, the increased power density also leads to heat dissipation issues for the conductors, making the utilization of air ducts even more crucial. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an uninterruptible power supply cabinet that does not conflict with the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this application to solve its technical problem is as follows: An uninterruptible power supply (UPS) cabinet is proposed, comprising a cabinet body and multiple functional modules and conductive busbar assemblies disposed within the cabinet body. At least one of the multiple functional modules is equipped with a fan assembly. The cabinet body has a front door and a rear door, and side panels are respectively disposed on the lower left and right sides between the front and rear doors. The multiple functional modules are disposed in the lower space between the side panels. The conductive busbar assemblies are disposed in the lower space of the cabinet body behind the multiple functional modules and in the upper space of the cabinet body. The front door has at least one ventilation hole facing the lower space. The rear door has a door panel that closes the lower space and a first air outlet facing the upper space. A second air outlet is disposed on the top of the cabinet body facing the rear of the multiple functional modules, and an inlet area is disposed in front of the second air outlet. Airflow enters the lower space from the front side of the cabinet body and is blocked by the rear door panel, rising upwards and exiting from the first air outlet of the rear door and the second air outlet on the top of the cabinet body.

[0005] According to one embodiment of the uninterruptible power supply cabinet described in this application, the side panels on the left and right sides of the cabinet respectively form a plurality of inwardly folded flanges, and the plurality of functional modules are installed on the flanges.

[0006] According to one embodiment of the uninterruptible power supply cabinet described in this application, the plurality of functional modules include a plurality of power modules, a bypass module and a control module arranged sequentially from bottom to top, and a fan assembly is provided on the front side of the plurality of power modules.

[0007] According to one embodiment of the uninterruptible power supply cabinet described in this application, the conductive busbar assembly includes a first conductive busbar group disposed behind and connected to the plurality of functional modules, and a second conductive busbar group disposed on the rear side of the upper space of the cabinet and connected to the first conductive busbar group.

[0008] According to one embodiment of the uninterruptible power supply cabinet described in this application, the uninterruptible power supply cabinet further includes a switch assembly disposed on the front side of the upper space of the cabinet and connected to the second conductive busbar group.

[0009] According to one embodiment of the uninterruptible power supply cabinet described in this application, the switch assembly includes a plurality of switch units, each switch unit having a switch body and a switch terminal, the switch body having a first connecting row extending rearward, and the switch terminal having a second connecting row extending forward, the first connecting row and the second connecting row overlapping each other to connect the switch body and the switch terminal.

[0010] According to one embodiment of the uninterruptible power supply cabinet described in this application, the cable entry area at the top of the cabinet is provided with multiple detachable cable entry plates.

[0011] According to one embodiment of the uninterruptible power supply cabinet described in this application, the front door is densely covered with ventilation holes in the upper and lower spaces of the cabinet.

[0012] The uninterruptible power supply (UPS) cabinet implementing this application has the following beneficial effects: According to the embodiments of this application, the lower part of the rear door of the UPS cabinet is a closed door panel, the upper part of the rear door is provided with a first air outlet, and the rear side of the top of the cabinet is provided with a second air outlet, thereby forming an air duct at the rear of the cabinet. The airflow enters from the front side of the lower space of the cabinet and then is blocked by the rear door panel, causing it to rise and carry away the heat from the conductive busbar assembly located at the rear of the cabinet. The air then flows out from the first air outlet of the rear door and the second air outlet at the top. Thus, this UPS cabinet can achieve top-mounted airflow and good heat dissipation without the need for a top-mounted fan assembly. Furthermore, since there is no top-mounted fan assembly, there is no conflict between top-mounted airflow and top-mounted cabling, eliminating the need to climb above the cabinet for fan maintenance, making it safer and more convenient. At the same time, the cabinet has a small footprint and low cost. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.

[0026] Figure 3 A schematic diagram of the structure of an uninterruptible power supply cabinet 100 according to an embodiment of this application is shown. Figure 4 and Figure 5 The diagrams show the structural schematics of the uninterruptible power supply cabinet 100 after removing the front door 11, viewed from the front right and rear left. (See also...) Figures 3 to 5 As shown, the uninterruptible power supply cabinet 100 mainly consists of a cabinet 10 and multiple functional modules 20, busbar assemblies 30, and switch assemblies 40 disposed within the cabinet 10. See details... Figure 3 As shown, the cabinet 10 has a front door 11 and a rear door 12, and side panels 13 are respectively provided on the lower left and right sides between the front door 11 and the rear door 12. See also Figure 4 As shown, multiple functional modules 20 are disposed in the lower space 14 between the two side panels 13, including multiple power modules 21, bypass modules 22, and control modules 23 arranged sequentially from bottom to top. At least one of the multiple power modules 21 has a fan assembly 24 on its front side, thereby forming an airflow duct on the front and rear sides of the multiple power modules 21. See also... Figure 5 As shown, the conductive busbar assembly 30 includes a first conductive busbar group 31 and a second conductive busbar group 32. The first conductive busbar group 31 is located behind and connected to the multiple functional modules 20 in the lower space 14 of the cabinet 10. The second conductive busbar group 32 is located on the rear side of the upper space 15 of the cabinet 10 and is connected to the upper end of the first conductive busbar group 31. The switch assembly 40 includes multiple switch units 41, located on the front side of the upper space 14 of the cabinet 10, and connected to the second conductive busbar group 32 respectively.

[0027] See also Figure 1 Combination Figure 6 As shown, the front door 11 of the cabinet 10 is densely covered with ventilation holes 111 facing the lower space 14 and the upper space 15. The lower part of the rear door 12 is a door panel 121 that closes the lower space 14, and the upper part has a first air outlet 122 facing the upper space 15. This first air outlet 122 can be composed of densely distributed air outlet holes. The top of the cabinet 10 has a second air outlet 16 facing the rear of the multiple functional modules 20, and a cable inlet area 17 is provided in front of the second air outlet 16. The cable inlet area 17 can be provided with multiple detachable cable inlet plates 171. By removing the cable inlet plates 171, the cables can be connected from the top of the cabinet 10.

[0028] According to the above embodiments of this application, the uninterruptible power supply cabinet 100 is designed with the lower part of the rear door 12 of the cabinet 10 being a closed door panel 121, the upper part of the rear door 12 being provided with a first air outlet 122, and a second air outlet 16 being provided on the rear side of the top of the cabinet 10, thereby forming an air duct at the rear of the cabinet 10. See also Figure 5 As shown, airflow enters the lower space 14 of the cabinet 10 from the front side through the ventilation hole 111 on the front door 11 (as shown by the first arrow 51), then enters the rear side of the lower space 14 through multiple functional modules 20 (as shown by the second arrow 52), is blocked by the door panel 121 of the rear door 12 and flows upward (as shown by the third arrow 53), carrying away the heat from the conductive busbar assembly 30 located at the rear of the cabinet 10, and then flows out from the first air outlet 122 of the rear door 12 (as shown by the fourth arrow 54) and the second air outlet 16 at the top (as shown by the fifth arrow 55). In this way, the uninterruptible power supply cabinet 100 can achieve top entry, top exit, and rear exit, with good heat dissipation effect, and there is no need to install a top exit fan assembly, so there is no conflict with the top entry, and there is no need to climb up to the top of the uninterruptible power supply cabinet 100 for fan maintenance, which is safe and convenient. At the same time, the cabinet has a small footprint and low cost.

[0029] See further Figure 7 As shown, in one embodiment of this application, the side panels 13 on the left and right sides of the cabinet 10 respectively form a plurality of inwardly folded flanges 131, and the aforementioned plurality of functional modules 25 are respectively mounted on the flanges 131. This flange design optimizes the previous method of installing functional modules 20 by assembling multiple parts such as guide rails and support plates into a design where the flange 131 is directly stamped from the side panel 13, which greatly reduces the number of parts and the number of screws required, reduces production assembly time, improves production efficiency, and reduces costs.

[0030] See further Figure 8 As shown, in one embodiment of this application, the switch unit 41 of the switch assembly 40 has a switch body 411 and a switch terminal 412 for connecting to the second conductive busbar 32. Furthermore, the switch body 411 has a rearwardly extending first connecting busbar 413, and the switch terminal 412 has a forwardly extending second connecting busbar 414. The first connecting busbar 413 and the second connecting busbar 412 overlap to connect the switch body 411 and the switch terminal 412. Thus, after a break is formed between the switch body 411 and the switch terminal 412, even if the switch terminal 412 cannot be removed from the front of the cabinet 10, the switch body 411 can be removed from the front of the cabinet 10 along with the switch body 411 by disconnecting the connection between the first connecting busbar 413 and the second connecting busbar 414, thus meeting the customer's need for front door maintenance.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
