Description

Technical Field

[0001] This utility model relates to data center control cabinets, and in particular to a precision power supply control cabinet for data centers. Background Technology

[0002] Patent document CN 216872515 U discloses a dual-loop rack structure for the data center industry, which Figure 1 It was revealed that the heat dissipation vents 32 are located on the left and right sides of cabinet 1, meaning that the internal heat dissipation airflow of cabinet 1 is horizontal. And as... Figure 2 As shown, a series of electrical components, such as the incoming circuit breaker 52, the outgoing circuit breaker 53, the incoming busbar 58, and the outgoing busbar 59, all face forward. Some of these components generate heat during operation, but because the front (front-to-back direction), which has a larger heat-generating area, is offset by 90 degrees from the airflow direction (left-right direction) of the heat dissipation duct, the contact heat exchange area is small, resulting in poor heat dissipation. Utility Model Content

[0003] The inventor is researching, without disclosing the details, a precision control cabinet for intelligent power supply in data centers with improved heat dissipation. The solution involves redesigning the electrical components in existing technology so that their front faces the heat dissipation ducts, thereby improving heat dissipation. However, this results in the electrical components being offset by 90 degrees from the cabinet door, making maintenance personnel unable to face the front of the components after opening the cabinet door, thus hindering maintenance.

[0004] This utility model aims to provide a precision control cabinet for intelligent power supply in data centers, which can improve heat dissipation and facilitate maintenance by maintenance personnel.

[0005] The data center intelligent power supply precision column head control cabinet has two fully enclosed side doors on the left and right sides to serve as the left and right side walls of the control cabinet, and mesh front doors and mesh rear doors on the front and rear sides to serve as the front and rear side walls, thus forming a front-to-back heat dissipation air duct; the control cabinet contains electrical component modules, with the front of the electrical component modules facing forward and aligned with the mesh front door.

[0006] Furthermore, the control cabinet is a vertically mounted, flat rectangular cabinet with a mesh front door and mesh rear door that are narrower than the fully enclosed side door.

[0007] Furthermore, the control cabinet includes a frame, with the mesh front door and mesh rear door hinged to the front and rear sides of the frame, respectively; the left and right sides of the frame are equipped with latching seats, and the two fully enclosed side doors are equipped with latching components, which are then latched into the corresponding latching seats by their respective latching components.

[0008] Furthermore, the upper part of the front of the frame electrical component module is equipped with an operating status indicator light, which is aligned with the upper mesh of the mesh front door so that maintenance personnel can observe through the upper mesh; the mesh front door has a non-mesh section below the upper mesh, and a touch screen is installed on the non-mesh section.

[0009] Furthermore, the electrical component module includes molded case circuit breakers, miniature circuit breakers, current transformers, and copper busbars.

[0010] Furthermore, the control cabinet contains two aviation connectors, one for connecting to municipal power and the other for connecting to a UPS power supply.

[0011] Furthermore, the top wall of the control cabinet has a cable inlet, which is a rectangle extending horizontally from left to right.

[0012] The beneficial effects are as follows: external air flows backward through the mesh front door to the front of the electrical component module, carrying heat from the front of the module out through the mesh rear door. Because the external airflow faces the front of the electrical component module, the contact area is large, resulting in good heat dissipation. Maintenance personnel can easily access the electrical component module by opening the mesh front door, making maintenance convenient. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1 and Figure 3As shown, the data center intelligent power supply precision rack control cabinet of this utility model includes a frame, which is an upright, flat cuboid. The frame has latching seats on both the left and right sides, and two fully enclosed side doors 2 are equipped with latching components, which are used to attach to the corresponding latching seats. A mesh front door 1 is hinged to the front of the frame, and a mesh rear door 3 is hinged to the rear, serving as the front and rear side walls of the control cabinet, thus forming a front-to-back heat dissipation airflow. Figure 2 As shown, the front of the electrical component module 4 is aligned with the mesh front door 1 (hidden in the figure). Figure 3 As shown, the upper part of the front of the electrical component module 4 is equipped with a running status indicator light 41. The running status indicator light 41 is aligned with the upper mesh 12 of the mesh front door 1, allowing maintenance personnel to observe the running status indicator light 41 through the upper mesh 12. Below the upper mesh 12, the mesh front door 1 has a meshless section 10, on which a touch screen 11 is mounted. The meshless section 10 and the running status indicator light 41 are offset in height to prevent obstruction. The control cabinet contains two aviation connectors 5, one for connecting to municipal power and the other for connecting to a UPS power supply, one for use and one for backup. A cable inlet 6 is provided on the top wall of the control cabinet; the cable inlet 6 is a horizontal rectangle. Cables from other equipment cabinets in the computer room enter the control cabinet through the cable inlet 6 and connect to the electrical component module 4. The electrical component module 4 draws power from the aviation connector 5.

[0019] Electrical component module 4 includes a molded case circuit breaker 42, a miniature circuit breaker 43, a current transformer 44, and a copper busbar 45. This is prior art, as described in patent document CN 207603034 U, and will not be elaborated further.

[0020] The front and rear mesh doors (1 and 3) are made of cold-rolled steel with densely packed perforations stamped on the surface, achieving a 70% opening rate. The hexagonal mesh shape provides excellent ventilation and heat dissipation, while also offering some shielding against electromagnetic interference and allowing for observation of equipment operation. This design is suitable for cabinets with high heat generation. Dustproof cotton can be added to the mesh doors to prevent dust accumulation. The front and rear mesh doors (1 and 3) are narrower than fully enclosed side doors, creating a narrow, elongated airflow channel inside the cabinet, thus increasing airflow and improving heat dissipation. The top panel is made of high-quality cold-rolled steel, possessing good strength, toughness, and corrosion resistance, and can withstand certain external impacts. The top panel features front and rear openings with pre-drilled cable entry holes for easy cable routing. To prevent dust and foreign object intrusion and maintain the overall aesthetics of the cabinet, the cable entry holes are covered with dedicated cable entry covers. These covers can be easily removed during equipment installation or cable laying, facilitating convenient operation. Depending on actual usage needs and heat dissipation planning, users can choose whether to pre-install fan mounting holes in the top panel. Users can decide whether to create fan mounting holes in the top panel based on the heat generation and heat dissipation requirements of the equipment inside the rack, in order to build an efficient ventilation and heat dissipation system and achieve precise temperature control inside the rack. If waterproofing is required, no holes other than the mounting holes will be made in the top panel.

[0021] The products are based on the ISO9001:2008 quality control system, MTL-STD-454N US military sheet metal standard, GB / T15396-1994 general technical standards for electronic equipment, and ANST / EIA-310 cabinet definition size standard.

[0022] The precision power distribution cabinet (PDC) is the core power management hub for data centers and high-end communication equipment rooms.
