Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the entire data center room temperature is lowered to cool high-heat-producing servers, then the cooling effect on servers is improved, but energy consumption increases and resources are wasted
Solution Approach 1:
The invention segments the cooling system into two distinct parts: a water-cooling subsystem for high-heat-producing hosts and an air-cooling subsystem for other devices. The water-cooling system includes cooling plates installed directly on high-heat-producing servers, while the air-cooling system uses traditional air conditioners for general room cooling. This segmentation allows each subsystem to operate independently and efficiently, cooling only what is necessary without wasting energy on unnecessary cooling of already-cooled areas.
Solution Approach 2:
The invention applies local quality by providing enhanced cooling (water cooling) specifically to high-heat-producing hosts that require it, while other devices continue to use standard air cooling. The cooling plates are selectively installed on servers with higher heat generation, creating localized high-performance cooling zones without compromising the entire room's thermal management efficiency.
2Temperature
If traditional water cooling systems are used for large data centers, then cooling capacity is sufficient, but water energy utilization rate is low and heat recovery is difficult
Solution Approach 1:
The invention converts the waste heat generated by high-heat-producing servers into a useful resource. The water-cooling system captures heat from servers through cooling plates, and this heat is then transferred to a heat exchange system that can recover and reuse the thermal energy. Instead of discarding this heat as waste, it is converted into a beneficial resource that can be used for other purposes, thereby reducing overall energy consumption and improving environmental sustainability.

AI summary
The present disclosure discloses a water-cooling system for a data center room including a data center room, and a host positioned inside the data center room. A cooling plate is installed on a lateral side of the host, a cooling chamber is provided inside the cooling plate, a refrigerating plate is arranged inside the cooling chamber, an injector head is installed on an inner wall of the cooling chamber, and an absorption pipe is arranged at a bottom of the cooling chamber. A lateral side of the cooling plate is communicated with a gas-liquid separator, where a liquid outlet of the gas-liquid separator is connected to a liquid transmission pipe. In the water-cooling system for the data center room, the host having higher heat production is water cooled by means of the cooling plate, to meet demands for cooling down the host having higher heat production.
