Existing data center power supply and thermal management systems face challenges in integrating high-power fuel cells and absorption refrigeration modules within standard dimensions, leading to unstable cooling and inefficient energy utilization, particularly in large-scale data centers.
Innovation Solution
A distributed fuel cell power supply cabinet is designed with a modified 42U cabinet integrating a fuel cell system, including a fuel cell stack, plate heat exchanger, and control modules, coupled with a thermal management system for server, fuel cell, and computer room cooling, utilizing a unified coolant circulation for stable cooling and hybrid electricity supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If absorption refrigeration equipment is directly integrated into the cabinet with fuel cells, then independent electricity consumption and cooling of a single cabinet can be achieved, but the specific physical arrangement of modular equipment in the cabinet and corresponding module dimensions are not described in detail, making it hard to integrate high-power server group, high-power fuel cell, and high-power absorption refrigeration module under conventional cabinet dimension
Solution Approach 1:
The cabinet is divided into distinct modular sections: the upper portion houses the server group and liquid-air heat exchanger, while the lower portion contains the fuel cell and absorption refrigeration equipment. This segmentation allows each component to be independently designed and positioned within standard cabinet dimensions, resolving the spatial arrangement complexity while maintaining independent operation capability.
Solution Approach 2:
The patent utilizes vertical space distribution within the cabinet, placing heavier equipment (fuel cell) at the bottom and lighter equipment (server group) at the top. This three-dimensional spatial arrangement optimizes weight distribution, heat management, and maintenance accessibility, enabling integration of high-power components without exceeding conventional cabinet dimensions.
2Adaptability or versatility
If absorption refrigeration equipment is integrated into the cabinet, then the system can achieve self-contained operation, but the cooling capacity required for cooling the server depends entirely on the heat generated by the fuel cells, and the response time of the heat source is long, which may result in shortage of server cooling capacity supply
Solution Approach 1:
The absorption refrigeration equipment is pre-positioned and thermally coupled to both the fuel cell heat source and the server cooling system. The thermal management system is designed with pre-established heat transfer pathways, allowing the refrigeration equipment to immediately utilize fuel cell heat for server cooling when the fuel cell operates, reducing response time while maintaining self-contained operation.
Solution Approach 2:
The liquid-air heat exchanger serves as an intermediary thermal management component that facilitates heat transfer from the fuel cell to the absorption refrigeration equipment, and subsequently to the server group. This intermediary mechanism stabilizes the thermal coupling between components, ensuring reliable cooling capacity supply even during transient operational states.
3Power
If the cabinet is customized for integrating fuel cells and refrigeration equipment, then high-power components can be integrated, but it is not conducive to promotional use due to deviation from standard 42U cabinet dimensions
Solution Approach 1:
The cabinet design maintains the standard 42U form factor while incorporating multiple functional zones that can accommodate different configurations of fuel cells, servers, and refrigeration equipment. This universal design allows the same cabinet template to be deployed across various applications and scales, facilitating promotional use and standardized manufacturing while still supporting high-power component integration through optimized internal layout.
