Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional data centre cabinets rely on air cooling, which is inadequate for high-density server setups, leading to inefficient heat dissipation and increased energy consumption due to their open structure and low ingress protection, resulting in local hotspots and reduced cooling efficiency.
Innovation Solution
A data centre cabinet equipped with a pressure spray system that uses a closed circuit of cooling liquid oil pumped through a distribution device to directly cool servers, with liquid distributors and an oil return system ensuring uniform flow and heat exchange, and a standardized module design for ease of installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air cooling methods are used in traditional cabinets, then the cooling system is simple to implement, but the cooling capacity is limited and cannot effectively cool high-density equipment
Solution Approach 1:
The patent transitions from air cooling to liquid cooling by introducing a closed-loop liquid cooling system with pumps, heat exchangers, and liquid distribution devices that directly contact server components, thereby significantly increasing cooling capacity while maintaining system implementability through modular design
2Productivity
If equipment density in the cabinet increases, then the data centre processing capacity increases, but the internal temperature rises sharply and cooling efficiency decreases
Solution Approach 1:
The liquid cooling system uses pumped liquid circulation with heat exchangers and distribution devices to maintain effective cooling even as equipment density increases, preventing temperature rise by actively managing heat removal through the closed-loop system
Solution Approach 2:
The system changes the cooling medium from air to liquid, fundamentally altering the heat transfer parameters and enabling effective cooling of high-density equipment by utilizing liquid's superior heat capacity and thermal conductivity
3Device complexity
If traditional open structure cabinets are used, then the cabinet structure is simple, but local turbulence and heat dissipation dead corners result in low heat dissipation efficiency and high energy consumption
Solution Approach 1:
The liquid cooling system replaces air-based convection with liquid-based heat transfer, eliminating turbulence and dead corner issues by directly contacting heat sources with cooling liquid through distribution devices, thereby improving heat dissipation efficiency and reducing energy consumption
Solution Approach 2:
The patent replaces the mechanical air circulation system with a liquid circulation system that uses pumps and controlled flow paths, substituting the reliance on natural convection and fan-driven air flow with a more controllable and efficient liquid-based heat removal mechanism

AI summary
A data center cabinet includes a cabinet body, an oil distribution device and a plurality of liquid distributors. The cabinet body includes a number of mounting racks. The cabinet body is sequentially mounted with a number of server housings from high to low. A server is placed in the server housing. A liquid distributor is provided above each of the server housings. The oil distribution device is connected to the liquid distributor via an oil intake device. Cooling liquid oil is pumped into the oil distribution device by a pump, the oil distribution device distributes oil flow to the liquid distributor under the pressure of the pump, and the liquid distributor sprays the cooling liquid oil to the server for cooling. The present invention also relates to a pressure spray system.
