Description

Technical Field

[0001] This utility model relates to the field of UPS power supply technology, specifically a rack-mounted UPS power supply. Background Technology

[0002] Rack-mounted UPS power supplies are uninterruptible power supplies designed specifically for standardized equipment environments such as data centers, server rooms, and network cabinets. Their core function is to ensure the stable operation of critical electrical equipment in the event of power failure, while also adapting to the space efficiency requirements of rack installation.

[0003] The existing utility model patent with publication number CN219247289U discloses a rack-mounted UPS power supply, including a power supply box. The bottom of the power supply box has multiple ventilation slots, and the top of the power supply box has multiple ventilation holes. A blocking plate is rotatably fitted on the upper side of the power supply box, and the blocking plate corresponds to the ventilation holes. Slots are provided on opposite sides of the power supply box, and door panels are installed on opposite sides of the power supply box, with the door panels corresponding to the slots. Multiple through slots are provided in the door panels, and a baffle corresponding to the through slot is elastically fitted on the side of the door panel closest to the inside of the power supply box, and the baffle corresponds to the blocking plate. In this utility model, the ventilation holes and through slots can be opened by rotating the blocking plate. The normally open ventilation slots and the closable ventilation holes and through slots dissipate heat inside the power supply box, thus adapting to heat dissipation under various temperatures and preventing excessively high or low internal temperatures from affecting the components of the UPS power supply.

[0004] The aforementioned power supply structure relies on a rigid mechanical linkage of "blocking plate - rotating shaft - push rod - baffle". The baffle is elastically reset by a spring. After long-term use, the rotating shaft is prone to jamming due to dust accumulation and metal oxidation, resulting in the blocking plate not rotating smoothly and making it impossible to accurately control the opening and closing status of the ventilation holes / channels. At the same time, the power supply box only has an air inlet and fan on one side, and the ventilation channels are only opened at the bottom, the channels are opened on both sides, and the ventilation holes are opened at the top. One-sided air intake can easily lead to uneven airflow distribution in the power supply box. The side away from the fan (such as the left side) may form a "windless zone". If the core components of the UPS (such as capacitors and inductors) are installed here, they are prone to overheating due to insufficient heat dissipation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rack-mounted UPS power supply that solves the problems of easy dust accumulation in the heat dissipation structure and poor heat dissipation performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A rack-mounted UPS power supply includes connecting plates, and a protective mechanism is provided between the connecting plates to provide protection for the power supply and dissipate heat during operation. The protective mechanism includes: The support assembly includes springs, a tubular housing is fixedly installed between the springs, an installation plate is fixedly installed inside the tubular housing, a power supply is fixedly installed above the installation plate, and a panel is fixedly installed at the left end of the tubular housing. A heat dissipation component, located inside the support component, is used to dissipate heat generated during power supply operation.

[0007] Preferably, the heat dissipation assembly includes a fan fixedly installed inside the tubular housing, a filter is fitted onto one side of the tubular housing, and limit rings are movably installed on the front and rear sides of the tubular housing, with a metal mesh fixedly installed inside the limit rings.

[0008] Preferably, a limiting frame is fixedly installed at the right end of the tubular shell, a magnet frame is adsorbed inside the limiting frame, a filter plate is fixedly installed inside the magnet frame, a grid plate is fixedly installed on one side of the limiting frame, and connecting bolts are inserted at the four corners of the grid plate.

[0009] Preferably, the springs are arranged in groups of three and installed at the front and rear ends of the upper and lower planar structures of the tubular outer shell. A strip-shaped groove is provided on one side of the connecting plate for bolts to connect with the frame. A vertical plate-shaped structure is provided on the left side of the mounting plate. The power socket is fitted into the plate-shaped structure on the left side of the mounting plate. The panel is fitted into the left end of the mounting plate.

[0010] Preferably, the fan is fixedly installed on the left and right ends of the front and rear facades inside the tubular housing, and the filter is fixed to one side of the fan by a limiting ring. The limiting ring has a cross-shaped structure at its center, and the limiting ring is movably connected to the housing by a threaded structure.

[0011] Preferably, the limiting frame and the grid plate are connected to the tubular outer shell by connecting bolts at the four corners of the grid plate, and the filter plate is adsorbed inside the limiting frame by a magnet frame. Beneficial effects

[0012] This invention provides a rack-mounted UPS power supply. Compared with the prior art, it has the following advantages: (1) The rack-mounted UPS power supply has fans that are not set on one side, but are distributed on the left and right ends of the front and rear facades inside the tubular shell, and the fans rotate in opposite directions. This multi-position, reverse alternating operation mode can form a uniform airflow circulation inside the tubular shell, avoiding the formation of "windless areas" in areas far from the fans due to single-sided air intake. Secondly, the left end of the tubular shell has a panel and mounting plate fitted together to seal the gap, and the right end has an intake and exhaust structure composed of a limit frame, filter plate and grid plate, forming a complete and stable airflow channel, ensuring that external cold air can continuously and evenly enter the interior, efficiently removing the heat generated by the power supply operation. At the same time, the alternating operation of the fans can continuously refresh the internal hot air, greatly improving the heat dissipation efficiency and solving the problem of overheating of core components due to insufficient heat dissipation.

[0013] (2) The fan of this rack-mounted UPS power supply does not rotate in one direction, but alternates between clockwise forward exhaust and reverse airflow: During forward exhaust, external air must pass through the filter plate and filter element before entering the tubular outer casing. Both can directly intercept dust in the air and prevent dust from contacting the heat dissipation structure; During reverse airflow, the internal air pressure rises and pushes the airflow from the inside to the outside through the filter plate and filter element. The impact force of the airflow will blow away the dust attached to the outside of the filter plate and filter element, achieving active dust removal. In addition, the filter plate is attracted to the limiting frame by a magnetic frame, and the limiting ring is connected to the tubular outer casing by a threaded structure. If deep cleaning is required later, the limiting ring and magnetic frame can be easily removed without complicated operation, further preventing dust from accumulating and blocking the heat dissipation channel for a long time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a rack-mounted UPS power supply includes a connecting plate 1, and a protective mechanism 2 is provided between the connecting plates 1 for providing protection for the power supply 214 and dissipating the heat generated during the operation of the power supply 214. The protective mechanism 2 includes: The support assembly 21 includes springs 211, a tubular housing 212 is fixedly installed between the springs 211, an installation plate 213 is fixedly installed inside the tubular housing 212, a power supply 214 is fixedly installed on the top of the installation plate 213, and a panel 215 is fixedly installed on the left end of the tubular housing 212. The springs 211 are in groups of three and are installed at the front and rear ends of the upper and lower planar structures of the tubular housing 212. A strip groove is provided on one side of the connecting plate 1 for bolts to connect with the frame. A vertical plate structure is provided on the left side of the installation plate 213. The socket of the power supply 214 is fitted into the plate structure on the left side of the installation plate 213. The panel 215 is fitted into the left end of the installation plate 213.

[0017] Specifically, the connecting plate 1 is symmetrically installed on the front and rear sides of the top and bottom surfaces of the tubular outer shell 212, and is connected to the canning outer shell 212 through the spring 211. The groove structure on the surface of the connecting plate 1 facilitates the connection of the protective mechanism 2 to the frame by bolts. The spring 211 is installed between the connecting plate 1 and the tubular outer shell 212 and can generate a certain deformation to reduce the impact of vibration of other equipment on the internal power supply 214 during operation. The tubular outer shell 212 can protect the internal power supply 214. The mounting plate 213 facilitates the fixed connection between the power supply 214 and the tubular outer shell 212. The panel 215 can seal the gap between the tubular outer shell 212 and the mounting plate 213.

[0018] A heat dissipation assembly 22, disposed inside the support assembly 21, is used to dissipate heat generated during the operation of the power supply 214. The heat dissipation assembly 22 includes a fan 221 fixedly installed inside a tubular housing 212. A filter 222 is fitted onto one side of the tubular housing 212. Limiting rings 223 are movably installed on both the front and rear sides of the tubular housing 212. A metal mesh 224 is fixedly installed inside the limiting rings 223. A limiting frame 225 is fixedly installed at the right end of the tubular housing 212. A magnet holder 226 is attracted inside the limiting frame 225. A filter plate 227 is fixedly installed inside the magnet holder 226. One side of the limiting frame 225... A grid plate 228 is fixedly installed, and connecting bolts 229 are inserted at the four corners of the grid plate 228. The fan 221 is fixedly installed at the left and right ends of the front and rear sides of the tubular shell 212. The filter 222 is fixed to one side of the fan 221 by a limiting ring 223. The limiting ring 223 has a cross-shaped structure in the center and is movably connected to the shell by a threaded structure. The limiting frame 225 and the grid plate 228 are connected to the tubular shell 212 by the connecting bolts 229 at the four corners of the grid plate 228. The filter plate 227 is attracted to the inside of the limiting frame 225 by a magnet frame 226.

[0019] Specifically, the fans 221 on the front and rear sides of the tubular housing 212 rotate in opposite directions, and the operation of the fans 221 alternates between clockwise and counterclockwise. When the fans 221 start and rotate clockwise, they can expel the air inside the tubular housing 212. By reducing the air pressure inside the tubular housing 212, external air is allowed to enter the tubular housing 212 through the grid plate 228 and filter plate 227. The filter plate 227 and grid plate 228 can intercept dust or large debris in the air. When the fans 221 rotate counterclockwise, they will expel the air from the tubular housing 212. Air enters the tubular housing 212, causing the internal air pressure to rise. The internal air can then be discharged through the filter plate 227 and the grid plate 228. As the airflow passes from the inside to the outside through the filter plate 227 and the filter element 222, the dust adhering to the outside of the filter plate 227 and the filter element 222 will be separated from the filter element 222 and the filter plate 227 under the influence of the airflow, thereby improving the service life of the filter element 222 and the filter plate 227. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0020] During operation, the connecting plate 1 is connected to the frame via bolts through a strip-shaped groove on one side, and the protective mechanism 2 is installed above the connecting plate 1. In the support assembly 21, three spring plates 211 are fixed to the front and rear ends of the upper and lower planar structures of the tubular outer shell 212, and the lower part of the spring plates 211 is connected to the connecting plate 1. The mounting plate 213 is fixed inside the tubular outer shell 212, and the power supply 214 is fixed above the mounting plate 213. The socket of the power supply 214 is fitted into the vertical plate-like structure on the left side of the mounting plate 213, and the panel 215 is fitted into the left end of the mounting plate 213 to seal the gap. During heat dissipation, the fans 221 on the left and right ends of the front and rear vertical surfaces inside the tubular outer shell 212 operate alternately clockwise. When the fans 221 rotate clockwise, the air inside the tubular outer shell 212 is discharged, and the external air passes through the grid on the right end of the tubular outer shell 212. Plate 228 (fixed to the tubular outer shell 212 by connecting bolts 229 at the four corners) and filter plate 227 (adsorbed into the limiting frame 225 by magnet frame 226, the limiting frame 225 being fixed to the right end of the tubular outer shell 212) enter the interior. At the same time, filter sheet 222 on one side of the tubular outer shell 212 is fixed to the side of fan 221 by limiting ring 223 (threadedly connected to the tubular outer shell 212, with internal fixed metal mesh 224) to assist in filtering air. When fan 221 rotates counterclockwise, external air enters the tubular outer shell 212, causing the internal air pressure to rise. The internal air is discharged through filter plate 227 and grid plate 228. When the airflow passes through filter sheet 222 and filter plate 227, it will drive the dust attached to the outside of both to be separated. At the same time, spring sheet 211 can reduce the impact of vibration of other equipment in the frame on power supply 214 through deformation.
