Description

Technical Field

[0001] This application relates to the field of power electronic equipment technology, and in particular to a UPS chassis and a UPS power supply device. Background Technology

[0002] A UPS (Uninterruptible Power System) is a voltage and frequency stabilized AC power supply that contains energy storage devices and primarily consists of a power board with rectifiers and inverters. It mainly utilizes energy storage devices such as batteries to provide uninterrupted power to computer, server, storage device, network equipment, and other computer, communication network systems, industrial control systems, and industrial equipment requiring continuous operation during power outages. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load. When the mains power is interrupted, the UPS immediately uses battery power to continue supplying AC power to the load, ensuring the load continues to operate normally and protecting the load's hardware and software from damage.

[0003] Currently, UPS chassis are typically rectangular in shape, generally composed of six side panels. A central partition is located inside the chassis, and the power board is mounted on this partition. This design results in a large number of components and low internal space utilization for the UPS chassis. Utility Model Content

[0004] This application discloses a UPS chassis and a UPS power supply device, aiming to provide a UPS chassis that can reduce the number of parts and improve the utilization of internal space.

[0005] One embodiment of this application provides a UPS chassis, comprising: A bracket, wherein a first opening is formed along a first direction; A side plate is provided to cover the first opening, and the bracket and the side plate enclose a cavity to form a receiving cavity. The receiving cavity has a second opening at both ends along the second direction.

[0013] In one embodiment, the bracket is made of metal or plastic.

[0014] One embodiment of this application also provides a UPS power supply device, including a UPS chassis as described above.

[0015] This application integrates three side walls of the UPS chassis into a C-shaped bracket, upon which side panels, a first back panel, and a second back panel are mounted.

[0023] A UPS (Uninterruptible Power System) is a voltage and frequency stabilized AC power supply that contains energy storage devices and primarily consists of a power board with rectifiers and inverters. It mainly utilizes energy storage devices such as batteries to provide uninterrupted power to computer, server, storage device, network equipment, and other computer, communication network systems, industrial control systems, and industrial equipment requiring continuous operation during power outages. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load. When the mains power is interrupted, the UPS immediately uses battery power to continue supplying AC power to the load, ensuring the load continues to operate normally and protecting the load's hardware and software from damage.

[0024] Currently, UPS chassis are typically rectangular in shape, generally composed of six side panels. A central partition is located inside the chassis, and the power board is mounted on this partition. This design results in a large number of components and low internal space utilization for the UPS chassis.

[0025] To address the aforementioned problems, this application proposes a UPS chassis to solve the technical issues raised above.

[0026] Please see Figure 1 In one embodiment of this application, the UPS chassis includes a bracket 1, a side plate 2, a first back plate 3, and a second back plate 4. The bracket 1 forms a first opening along a first direction, and the side plate 2 covers the first opening. The bracket 1 and the side plate 2 enclose a receiving cavity 1a. The receiving cavity 1a forms a second opening at both ends along a second direction. The first back plate 3 covers one of the second openings, and the second back plate 4 covers the other second opening.

[0027] This application integrates three side walls of the UPS chassis into a C-shaped bracket 1, and then mounts side panels 2, a first back panel 3, and a second back panel 4 on the bracket 1. This reduces the number of components and eliminates the internal partition, thereby improving the space utilization within the chassis. Specifically, the UPS chassis includes a bracket 1, side panels 2, a first back panel 3, and a second back panel 4. The bracket 1 forms a first opening along a first direction, i.e., the width direction of the chassis, and the side panel 2 covers the first opening. The bracket 1 forms two opposing second openings along a second direction, i.e., the length direction of the chassis, and the first back panel 3 and the second back panel 4 are respectively mounted on one of the second openings. The bracket 1, side panels 2, first back panel 3, and second back panel 4 together form a cuboid chassis structure. In this design, the bracket 1 reduces the number of chassis components, simplifies the assembly process, and reduces assembly errors. Furthermore, it serves as the mounting base for the power board 5, thereby eliminating the internal partition and improving the space utilization of the accommodating cavity 1a. Furthermore, the structural strength of the chassis is improved by using a one-piece molded bracket 1.

[0028] Please see Figure 1Specifically, the bracket 1 includes a first horizontal plate 11, a second horizontal plate 12, and a vertical plate 13. The first horizontal plate 11 and the second horizontal plate 12 are respectively located at opposite ends of the vertical plate 13, and are arranged parallel to each other. The vertical plate 13 serves as the intermediate load-bearing structure. The first horizontal plate 11 and the second horizontal plate 12 are respectively vertically located at opposite upper and lower ends of the vertical plate 13, maintaining strict parallelism. All three components are manufactured using a one-piece molding process, presenting a neat C-shaped structure without the need for additional splicing parts. This one-piece molding structure not only reduces the number of connectors required for splicing multiple parts in traditional chassis bracket 1, reducing cumulative errors during assembly and making the assembly process simpler and more efficient, but also significantly improves the structural stability and load-bearing strength of the bracket 1 itself. Meanwhile, the C-shaped open design allows the vertical plate 13 to be directly used as the mounting base for the power board 5. Precise installation is achieved by matching the fixing posts 131 on the vertical plate 13 with the fixing holes of the power board 5, eliminating the need for an additional partition inside the chassis. This frees up the space occupied by the partition, significantly improving the overall space utilization of the housing 1a and providing more space for the layout of other components inside the chassis. Furthermore, the direct contact installation of the power board 5 with the vertical plate 13 lays the foundation for the subsequent heat dissipation structure.

[0029] To limit and fix the side plate 2, the first horizontal plate 11 is provided with a first locking plate 111 at the end away from the vertical plate 13, the second horizontal plate 12 is provided with a second locking plate 121 at the end away from the vertical plate 13, and the opposite sides of the side plate 2 are provided with a third locking plate 21, one of which is engaged with the first locking plate 111, and the other of which is engaged with the second locking plate 121. The third locking plate 21 at the upper end of the side plate 2 forms a sliding fit with the first locking plate 111, and the third locking plate 21 at the lower end of the side plate 2 forms a sliding fit with the second locking plate 121. The first locking plate 111 and the second locking plate 121 are equivalent to providing a precise sliding rail structure for the installation of the side plate 2. This not only strictly limits the installation direction and position of the side plate 2 to prevent offset during installation, but also allows the side plate 2 to be quickly embedded into the first opening of the bracket 1 through the sliding fit, achieving a pre-fixing effect and laying the foundation for further fixation. At the same time, this snap-fit ​​structure does not require additional connecting parts, which simplifies the assembly process and ensures the stability of the connection between the side plate 2 and the bracket 1, making the cavity 1a structure formed by the two more regular.

[0030] The UPS chassis also includes a power board 5, which has multiple mounting holes, and a vertical plate 13 with multiple mounting posts 131, each post 131 passing through a mounting hole. This design eliminates the need for an additional partition, utilizing the integrally molded vertical plate 13 as the mounting base, significantly reducing the number of internal components and freeing up space occupied by the partition, thus significantly improving the space utilization of the housing 1a and reserving ample space for other components. The corresponding fit between the mounting posts 131 and the mounting holes enables rapid positioning and precise assembly of the power board 5, simplifying the installation process, reducing assembly errors, and providing strong connection stability, preventing displacement of the power board 5 due to vibration during use. Furthermore, the direct contact installation of the power board 5 and the vertical plate 13 not only enhances the load-bearing stability of the power board 5 with the help of the vertical plate 13, but also lays the structural foundation for adding thermal conductive silicone 132 between them to improve heat dissipation efficiency, ensuring the stable operation of core components such as the rectifier and inverter on the power board 5.

[0031] The basic working principle of the UPS power supply unit is as follows: When the mains power is input normally, the rectifier on the power board 5 first converts the AC mains power into DC power. Part of it charges the energy storage device, and the other part is converted into stable AC power by the inverter to supply the load. When the mains power is interrupted, the energy storage device immediately releases DC power, which is converted into AC power that meets the load requirements by the inverter on the power board 5 to continuously supply power to the load. At the same time, the power board 5 is stably installed through the precise cooperation between the fixing post 131 on the vertical plate 13 and its own fixing hole, ensuring the stable operation of the power conversion and power supply process, and avoiding damage to the load software and hardware due to power failure or unstable power.

[0032] In some embodiments, thermally conductive silicone 132 is provided between the power board 5 and the vertical plate 13. For details, please refer to further reading. Figure 4 The placement of thermally conductive silicone 132 between the power board 5 and the vertical plate 13 serves several purposes. Firstly, the excellent thermal conductivity of the silicone 132 allows for rapid heat transfer from the rectifier, inverter, and other core components on the power board 5 to the vertical plate 13, preventing performance degradation or damage due to excessive heat buildup and ensuring stable operation of the UPS power supply. Secondly, the soft material of the silicone 132 forms a buffer layer between the power board 5 and the vertical plate 13, effectively absorbing vibrations and impacts during transportation or use. This reduces friction and stress damage between the power board 5 and the fixing posts 131 and the vertical plate 13, while also filling the small gaps between them, resulting in a more secure and fitted installation of the power board 5 and further enhancing structural reliability.

[0033] In some optional embodiments, a first bent skirt 31 is provided on the side of the first backplate 3 facing the bracket 1, and a second bent skirt 41 is provided on the side of the second backplate 4 facing the bracket 1, and both the first bent skirt 31 and the second bent skirt 41 are snapped into the bracket 1. Taking the first backplate 3 as an example, the snap-fit ​​structure can realize the rapid positioning and pre-fixation of the first backplate 3 and the bracket 1, greatly simplifying the assembly process, reducing installation time, and reducing the error of positional offset during assembly; secondly, the first bent skirt 31 increases the contact area between the first backplate 3 and the bracket 1, and with the tight fit of the snap-fit, the connection between the two is more stable, improving the sealing and vibration resistance of the overall chassis structure and preventing the backplate from loosening. The first bent skirt 31 can also strengthen the edge of the first backplate 3, enhance the structural strength of the first backplate 3 itself, prevent it from deforming due to force or collision during transportation, and provide a stable installation base for possible subsequent threaded connections, further ensuring the assembly reliability of the chassis. The first back plate 3 is threadedly connected to the bracket 1 and the side plate 2 respectively via the first bent skirt 31; the second back plate 4 is threadedly connected to the bracket 1 and the side plate 2 respectively via the second bent skirt 41.

[0034] The air inlet 3a of the first backplate 3, the air outlet 4a of the second backplate 4, and the cavity 1a form a through-flow channel extending in the second direction, creating a directional and unobstructed heat dissipation path. After entering through the air inlet 3a, external cold air can flow directly through the power board 5 and other core heat-generating components along the air channel, quickly carrying away the heat generated during operation, and then being discharged from the air outlet 4a, greatly improving heat dissipation efficiency and preventing components from aging or malfunctioning due to high temperatures. At the same time, the air channel fits the internal structure of the chassis, eliminating the need for additional air guide components, making full use of the space in the cavity 1a, not occupying the installation position of other components, and the directional airflow can reduce dust accumulation. Combined with the chassis sealing structure, this not only ensures heat dissipation stability but also extends the service life of the UPS device, ensuring stable performance during long-term operation.

[0035] It should be noted that the material of the bracket 1 can be either metal or plastic, and this application does not impose any restrictions on it.
