Integrated Access Door Layout for Data Center Power and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power distribution and monitoring systems in modular data centers occupy excessive space and require multiple cabinets, leading to reduced IT load capacity and increased cable connections, while separate control systems for monitoring, lighting, and access control are cumbersome and inefficient.
Innovation Solution
An integrated access door that combines power distribution, monitoring, lighting control, access control, and fire control systems, utilizing a multi-compartment design with heat dissipation and quick connection ports to reduce space occupancy and simplify cable management, and incorporates a door system for channel isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If UPS and power distribution cabinet are used separately, then power distribution function is achieved, but two positions for server cabinet are occupied, resulting in significant reduction in installed capacity of IT loads
Solution Approach 1:
The patent combines the UPS (uninterruptible power supply) and power distribution cabinet into a single integrated unit. This merging eliminates the need for two separate cabinet positions, thereby increasing the installed capacity for IT loads while maintaining complete power distribution functionality including power supply, distribution, and monitoring capabilities.
Solution Approach 2:
The integrated access door serves multiple functions simultaneously: it provides power distribution through integrated UPS and power distribution cabinets, monitoring through integrated monitoring cabinets, access control, and channel isolation. This multi-functionality reduces the total number of cabinet positions required in the data center.
2Area of stationary object
If integrated UPS power distribution cabinet is used, then occupation of one position for cabinet is reduced, but it is limited to N+1 system and cannot meet requirements of 2N power supply and distribution system
Solution Approach 1:
The integrated access door is divided into multiple independent functional modules including separate UPS units, power distribution cabinets, and monitoring cabinets. Each module can be independently configured to meet different power supply requirements (N+1, 2N, or other configurations), providing adaptability while maintaining space efficiency.
3Area of stationary object
If intelligent bus system is used to supply power to IT loads, then occupation of cabinet position is reduced, but additional power distribution boxes are still needed for cooling system, lighting system and other systems
Solution Approach 1:
The integrated access door provides universal power distribution capabilities through its integrated power distribution cabinet that can supply power to all systems (IT loads, cooling systems, lighting systems, etc.) through a unified interface, eliminating the need for multiple separate power distribution boxes and reducing overall device complexity.
4Adaptability or versatility
If different controllers or control boxes are configured for monitoring, lighting and access control functions, then these functions are realized, but devices mounted in cabinet occupy U-bit space of IT load and devices mounted on top are not convenient for construction and operation
Solution Approach 1:
The patent integrates monitoring controllers, lighting controllers, and access control controllers into the integrated access door structure. These control devices are mounted within the door body rather than in separate locations, making them convenient for construction (pre-fabricated) and operation (centralized access) while not occupying U-bit space from IT loads.
5Area of stationary object
If control devices are mounted in server cabinet, then U-bit space of IT load is occupied, but if mounted on top of cabinet, then construction and operation are not convenient and devices cannot be fixed easily
Solution Approach 1:
Instead of mounting control devices in the horizontal plane (occupying U-bit space) or on the top surface of cabinets, the patent utilizes the vertical door structure as a third dimension for mounting. The integrated access door provides dedicated mounting spaces within its structure, optimizing the spatial arrangement and making devices easily accessible for construction and operation without affecting IT load space.
6Device complexity
If specific wiring route is designed for control devices, then cable layout is planned, but it is required to be laid on site and construction quality is difficult to control
Solution Approach 1:
The integrated access door comes with pre-designed and pre-configured wiring routes and cable channels built into its structure during manufacturing. This preliminary action allows cables to be routed through dedicated pathways within the door, eliminating the need for complex on-site cable layout planning and ensuring consistent construction quality without requiring extensive on-site work.
