Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional ice water circulating cooling device is used, then cooling circulation is achieved, but considerable power is consumed to cool the cooling water
Solution Approach 1:
The patent converts the waste heat from server components into a useful resource by using it to pre-cool the cooling water through heat exchange, transforming what would be wasted thermal energy into a beneficial cooling effect that reduces the load on the chiller system
Solution Approach 2:
The patent introduces a heat exchange device as an intermediary between the server components and the cooling water circulation system. This intermediary enables indirect cooling where the cooling water is pre-cooled by exchanging heat with the server's internal cooling structures, reducing the energy required by the main cooling system
2Temperature
If direct pipeline cooling is used, then cooling is achieved, but operation temperature cannot be precisely controlled
Solution Approach 1:
The patent implements temperature sensing and control mechanisms that continuously monitor the cooling water temperature and adjust the cooling system operation accordingly. This feedback loop enables precise control of the operation temperature by dynamically adjusting cooling parameters based on actual temperature conditions
Solution Approach 2:
The patent transitions from a static cooling system to a dynamic one where cooling parameters such as water flow rate and temperature can be adjusted in real-time. This dynamic control allows the system to adapt to varying thermal loads and maintain precise temperature control throughout operation
3Area of stationary object
If servers are closely arranged to save space, then space efficiency is improved, but heat dissipation becomes insufficient
Solution Approach 1:
The patent employs a liquid-based cooling system (water circulation) that can be efficiently routed through densely packed server configurations. The hydraulic cooling infrastructure enables effective heat removal even when servers are closely arranged, as the liquid cooling paths can be optimized to reach heat-generating components regardless of spatial constraints

AI summary
A cooling system for a server includes at least one radiator and at least one cooling plate that are installed in a server cabinet, a cooling assembly, a storage tank, and a heat exchanger. The cooling assembly is connected to the radiator, and is carried with a first cooling fluid therein. The storage tank is connected to the cooling plate, and is carried with a second cooling fluid therein. The first cooling fluid enters the heat exchanger through the radiator, and the second cooling fluid enters the heat exchanger through the cooling plate. The first cooling fluid and the second cooling fluid perform heat exchange in the heat exchanger, so as to reduce the temperature of the second cooling fluid, thus reducing the required energy enabling the second cooling fluid to return to a set temperature.
