Centralized Power Distribution for Data Center Rack Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data center rack cabinets, the bulky power supply units restrict device density, hinder heat dissipation, and require manual intervention for maintenance, leading to labor-intensive and time-consuming device resumption during breakdowns or shutdowns, limiting flexible utilization.
Innovation Solution
A device management system with a remotely-controllable switching circuit and detecting circuit allows individual and remote control of devices, enabling selective power distribution and real-time monitoring, reducing the need for manual intervention and enhancing maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supply units are installed in each device, then devices can be independently powered, but device volume becomes bulky and heat dissipation is insufficient
Solution Approach 1:
The power supply function is extracted from individual devices and centralized into a shared power supply unit within the rack cabinet. This allows devices to lose their internal power supply components, reducing device volume while maintaining independent power control through the centralized unit's switching circuits.
Solution Approach 2:
A single centralized power supply unit serves multiple devices simultaneously, providing universal power distribution. The unit can independently control power to each device through remotely-controllable switching circuits, achieving both centralization and individual control.
2Reliability
If power supply units are installed in each device, then devices can be independently powered, but heat dissipation efficacy is unsatisfied
Solution Approach 1:
Power supply units are extracted from individual devices and consolidated into a centralized unit with dedicated heat dissipation capabilities. This separates the heat generation function from device locations, allowing optimized thermal management in a centralized location rather than distributed throughout multiple devices.
3Reliability
If power distribution unit stops providing power to all devices when one device breaks down, then power safety is ensured, but device utilization flexibility is impaired
Solution Approach 1:
The power distribution system is segmented into individual controllable circuits for each device, with remotely-controllable switching circuits that can independently control power to each device. This allows the power system to maintain safety by isolating faulty devices while continuing to supply power to healthy devices, rather than shutting down the entire system.
4Ease of repair
If manual intervention is required to resume devices after breakdown, then device maintenance can be performed, but maintenance is time-consuming and labor-intensive
Solution Approach 1:
The system enables self-service through automated device management. When a device breaks down, the system automatically detects the fault, isolates the affected device by controlling switching circuits, and can automatically resume or replace devices without requiring manual intervention. This eliminates the need for workers to physically access and check each device sequentially.
Solution Approach 2:
The system incorporates feedback mechanisms that automatically detect device status and trigger appropriate responses. When a device fails, the system receives feedback about the failure and automatically executes remediation actions such as isolating the faulty device or activating backup devices, reducing the need for manual maintenance intervention.
5Difficulty of detecting and measuring
If workers must move through the data center to check all devices for breakdown, then faulty devices can be identified, but the process is labor-intensive and time-consuming
Solution Approach 1:
The system uses automated feedback mechanisms to detect device faults. Sensors and monitoring circuits continuously check device status and automatically report failures to the management system, eliminating the need for workers to physically inspect each device. The system identifies faulty devices through electrical status feedback rather than manual checking.
Solution Approach 2:
The manual mechanical inspection process is replaced with automated electrical and electronic detection systems. Instead of workers physically moving through the data center to check devices, the system uses remotely-controllable switching circuits and detection circuits to automatically identify faulty devices through electrical status monitoring.

The device management module (2) includes at least one remotely-controllable switching circuit (22) and a detecting circuit (21). When a device (90) is installed in the rack cabinet (9), the remotely-controllable switching circuit (22) connected with the device (90) is enabled by the detecting circuit (21). The remote management module (11) is in communication with the remotely-controllable switching circuit (22) and the detecting circuit (21) through the bus bar (12). The information of the device (90) is acquired by the remote management module (11) through the remotely-controllable switching circuit (22). A switch element (226) of the remotely-controllable switching circuit (22) which is connected to the device (90) is selectively turned on or turned off by the remote management module (11). When the switch element (226) is turned on, the DC power (Vdc) is transmitted to the device (90) through the switch element (226).
