High-voltage DC Cabinet Enclosure for Data Center

High-voltage DC Cabinet Enclosure for Data Center

The high-voltage DC cabinet housing for data centers is a high-end precision sheet metal cabinet structural component specially developed for large data centers, computer room power supply systems, and new energy DC transmission and distribution equipment. As the load-bearing and protective main body of the high-voltage DC power distribution system, it is mainly used to integrate high-voltage DC switches, rectifier modules, power distribution units, and monitoring and protection components. Realizing the sealed protection, insulation isolation, heat dissipation ventilation and safety protection of high-voltage direct current power supply equipment is the core basic sheet metal equipment for the stable operation of the power supply and distribution system in data centers.

The casing is made of high-quality cold-rolled steel plates, galvanized steel plates or aluminum alloy plates through precise sheet metal processing. It is formed by laser cutting, CNC bending, precise welding and reinforced riveting. The overall structure has high strength, good load-bearing capacity and is not easy to deform. It can meet the harsh usage conditions of long-term full-load operation of data center equipment and dense placement of equipment in the computer room. The surface is treated with electrostatic powder coating, anti-corrosion acid washing and phosphating processes. The paint film has strong adhesion, is scratch-resistant and wear-resistant, dust-proof and rust-proof, and has excellent anti-aging, anti-static and weather resistance properties, making it suitable for the constant temperature and humidity, long-term continuous operation environment of the computer room.

The cabinet adopts a standardized modular structure design, with a regular overall layout. Inside, standard installation beams, cable trays, and equipment installation positions are reserved, facilitating the regular assembly of DC modules, circuit breakers, monitoring instruments, and wiring harness systems. The body is equipped with professional heat dissipation air ducts, ventilation louvers and dust-proof net structures, which can quickly dissipate the working heat of high-voltage DC equipment, prevent high-temperature heat accumulation and overload faults of the equipment, and ensure the long-term stable operation of the power distribution system. At the same time, it is equipped with high-strength insulation protection structures and safety isolation baffles, effectively eliminating the risks of high-voltage leakage, arc damage and short circuits, and comprehensively enhancing the safety level of high-voltage DC equipment operation.

The product supports IP high-level protection design. The cabinet body is precisely fitted and has good sealing performance, which can effectively prevent dust, moisture and debris from entering the interior of the cabinet, and prevent components from accumulating dust and getting damp, thus avoiding malfunctions. The cabinet door is equipped with a dedicated connecting rod lock multi-point locking structure, which is tightly closed, shock-resistant and anti-loosening. It eliminates problems such as door loosening, abnormal noise and dust leakage from gaps caused by the vibration of equipment operation in the computer room. It also has the functions of anti-theft, anti-mis-opening and safety protection. The overall disassembly and assembly are convenient and the maintenance is simple, which is suitable for the construction of standardized data center computer rooms and the later operation and maintenance inspection requirements.

It is widely applied in large-scale Internet data centers, operator computer rooms, cloud computing centers, energy storage DC power distribution systems, and industrial high-voltage DC power supply scenarios. It supports non-standard dimensions, internal structures, opening layouts, and customized heat dissipation solutions. It can be customized according to the customer's electrical schematic diagram, equipment parameters, and computer room layout, and is suitable for use with various high-voltage DC complete sets of power distribution equipment.

Model: OEM/ODM

Base materials: Hot-dip galvanized steel sheet, cold-rolled steel sheet (SPCC), aluminum-zinc coated sheet

Processing technology

1. Cutting and blanking: The CNC shearing machine cuts the standard size of the sheet.

2. CNC punching/laser cutting: Processing elliptical holes for display screens, cable holes, screw installation holes, heat dissipation holes, mesh holes, and multiple punching of door panels.

3. Riveting process: Riveting of nuts and studs

4. Sheet metal bending: Bend the side walls of the box, door frames, and rounded corner contours in one piece.

5. Welding processing: Spot welding/seamless full welding of the corners and edges of the box to ensure airtightness and waterproofing.

6. Grinding and leveling: Weld seams are ground and polished to remove burrs, sharp corners and edges, and the door panels are leveled by roller pressing.

Packaging

1. Inner wall buffer protection: The entire inner wall of the cabinet is fully covered and wrapped with pearl cotton. The corners of the cabinet, heat dissipation holes, door frame seams and other easily bumped areas are thickened with pearl cotton for buffering to prevent the paint surface from being scratched and the cabinet from deforming due to transportation jolts and compression.

2. Built-in moisture-proof and rust-proof: Desiccants are placed inside the cabinet to absorb the condensed water vapor caused by the temperature difference in the Marine container, preventing the steel plates from getting damp and rusting.

3. Overall sealed and water-proof: The entire cabinet is fully wrapped with PE moisture-proof and waterproof film on the outside, preventing seawater, fog and moisture from entering.

4. Carton + corner protection reinforcement: The outer layer is covered with thickened seven-layer export corrugated cartons, and solid wood corner protectors are installed at the four corners of the box for hard protection to avoid collision and compression during loading and unloading.

5. Bulk shipment: ISPM15 solid wood pallets are fully assembled. The cabinet bodies are neatly stacked on the heat-treated ISPM15 solid wood pallets. The entire pallet is tightly fixed with stretch film, meeting the wooden quarantine standards of customs in various countries around the world. It is convenient for forklift loading and unloading and container stacking for ocean transportation.

6. Extra-large multi-compartment cabinet: Packed in IPPC plywood wooden box. This three-compartment large-sized cabinet is preferred to be packed in a fumigation-free IPPC plywood sealed wooden box. The box body has stronger rigidity, better sealing performance, higher shock and moisture resistance for long-distance sea transportation, and is convenient for customs clearance without quarantine obstacles.

Logistics: Sea freight, air freight, international express delivery (DHL, FedEx, UPS, TNT), railway transportation (mainly China-Europe Railway Express), road and land transportation (short-distance foreign trade with neighboring countries)
