Technical Field

[0001] This utility model relates to the field of UPS cabinet technology, and in particular to a novel cabinet for a dual-module UPS power supply. Background Technology

[0002] UPS cabinets are dedicated cabinet systems used in data centers and critical power environments to integrate uninterruptible power supplies (UPS) and related power distribution equipment. Their core function is to ensure the continuity and security of power supply. Currently, UPS cabinets only have a single power module. When a UPS power module experiences a thermal failure, the entire cabinet must be shut down for maintenance, compromising power continuity. Furthermore, the current UPS power modules are complex to disassemble and assemble, requiring highly skilled maintenance personnel, resulting in long overall maintenance times. Therefore, further improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a new type of cabinet with dual-module UPS power supply to address the above problems.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] like Figures 1-2As shown, a novel cabinet for a dual-module UPS power supply includes a cabinet 1, a first power module 2 and a second power module 3. A battery compartment 11 is provided at the bottom of the cabinet 1. Two parallel and spaced heat dissipation partitions 4 are provided inside the battery compartment 11. A flip-up cover 12 is provided on the back side of the cabinet 1. The cover 12 is used for the battery compartment 11. The first power module 2 and the second power module 3 are detachably mounted on the two heat dissipation partitions 4. Ventilation holes 13 are provided on both side walls of the battery compartment 11. A cooling fan 5 is provided inside the battery compartment 11 facing the ventilation holes 13. The two heat dissipation partitions 4 are hollow and are connected to the air outlets of the two cooling fans 5 one-to-one. Several heat dissipation fins 41 are provided inside the heat dissipation partitions 4 extending along the airflow direction. Specifically, the cabinet 1 is constructed using sheet metal and a metal frame to protect the built-in electronic equipment. A battery compartment 11 is located at the bottom of the cabinet 1 to house the first power module 2 and the second power module 3. The first power module 2 and the second power module 3 are independent power modules that supply power to the electrical equipment within the cabinet 1, without interfering with each other. If either the first power module 2 or the second power module 3 fails or its power consumption is too low after a power outage, and replacement is required, the backup first power module 2 or the second power module 3 can continue to provide power, supporting power replacement without shutting down the system and ensuring continuous power supply. Furthermore, the battery compartment 11 is sealed with a cover 12 for dust protection and contains a heat dissipation baffle 4. This baffle not only supports the first power module 2 or the second power module 3 but also serves as a heat dissipation channel for cooling the first power module 2 or the second power module 3. Specifically, this design employs air-cooled heat dissipation. Two cooling fans 5 are installed within the battery compartment 11. The air outlets of the cooling fans 5 are connected to the heat dissipation partition 4. When the cooling fans 5 are activated, they draw in outside air through adjacent vents 13 and blow it into the heat dissipation partition 4. Following the guide of the heat dissipation partition 4, the airflow exits through another vent 13. The low-temperature airflow, after passing through the heat dissipation partition 4, effectively removes heat transferred from the first power module 2 or the second power module 3 to the heat dissipation partition 4, preventing heat accumulation in the battery compartment 11. Overheating can lead to performance degradation of the first power module 2 or the second power module 3, reducing its lifespan. To improve heat dissipation efficiency, heat dissipation fins 41 are integrated within the heat dissipation partition 4, positioned along the airflow direction. The heat dissipation fins 41 divide the cross-section of the heat dissipation partition 4 into a racetrack shape and also enhance the structural strength of the heat dissipation partition 4 itself.

[0016] Specifically, the heat dissipation fins 41 are wavy, which increases the length of the heat dissipation fins 41 within the heat dissipation partition 4, thereby increasing the air-cooled heat dissipation area and improving heat dissipation efficiency.

[0017] Specifically, the applicant tilts the heat dissipation partition 4, with the outer vertical height of the partition 4 being greater than the inner vertical height. When installing the first power module 2 and the second power module 3, because the first power module 2 and the second power module 3 are relatively heavy, generally exceeding 4 kg, tilting the heat dissipation partition 4—specifically, tilting it inwards towards the battery compartment 11—lowers its height. This allows the first power module 2 and the second power module 3 to slide down the heat dissipation partition 4 to the bottom of the battery compartment 11 under their own weight, completing the electrical connection with the built-in circuit module of the battery compartment 11, making assembly easier.

[0018] like Figure 2 As shown, the first power module 2 and the second power module 3 are provided with handles 21 at their front ends, and plugs are provided at their rear ends, with sealing rings surrounding the plugs. The handles 21 are movably connected to the front ends of the first power module 2 and the second power module 3 via pins, allowing the handles 21 to be flipped to avoid obstructing the closing of the cover 12. A sealing ring is designed around the plug to protect the electrical connection between the plug and the battery compartment 11, achieving a dustproof and waterproof seal.

[0019] like Figure 2 As shown, the rear ends of the first power module 2 and the second power module 3 have notches, and spring guide posts 22 are provided at the notches. Specifically, in order to prevent the first power module 2 and the second power module 3 from sliding down the heat dissipation plate 4 too quickly and causing damage to the electrical connection between the rear plug and the battery compartment 11, the spring guide posts 22 are inserted into the corresponding grooves in the battery compartment 11 as a buffer to protect the plug and thus improve the service life of the plug.

[0020] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
