Solution Overview
Problem
Conventional refrigerant-type cooling distribution units (CDU) face inefficiencies due to temperature rise of refrigerant after heat exchange with electronic components, necessitating re-cooling within the CDU to maintain low temperatures.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling distribution unit re-cools the returned refrigerant to maintain low temperatures, then the refrigerant temperature is maintained, but the energy consumption and operational complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-cooling the refrigerant in the liquid cooling row before it returns to the cooling distribution unit. The refrigerant flows through the liquid cooling row where it undergoes heat exchange with the condensation area, adapter assembly, and flow distribution row, cooling itself in advance before re-entering the CDU. This eliminates the need for the CDU to perform additional re-cooling operations, thereby maintaining refrigerant temperature while reducing energy consumption and operational complexity.
2Loss of energy
If the refrigerant undergoes heat exchange with electronic components, then heat dissipation is achieved, but the refrigerant temperature rises requiring re-cooling
Solution Approach 1:
The patent converts the harmful effect of temperature rise into a beneficial pre-cooling opportunity. After the refrigerant absorbs heat from electronic components and its temperature rises, it is directed through the liquid cooling row where it pre-cools itself before returning to the CDU. The temperature rise that would normally require energy-intensive re-cooling is instead utilized as a driving force for the pre-cooling process in the liquid cooling row, transforming a problem into a solution.
3Temperature
If a separate pre-cooling system is added to cool the refrigerant before it returns to the CDU, then temperature maintenance improves, but the device complexity increases
Solution Approach 1:
The patent merges the pre-cooling function with the existing cooling distribution unit by integrating the liquid cooling row into the CDU's flow path. The liquid cooling row, adapter assembly, and flow distribution row are incorporated as integral components of the CDU, allowing the refrigerant to pre-cool itself within the existing system architecture. This integration achieves improved temperature maintenance without adding separate, independent pre-cooling equipment, thereby avoiding excessive device complexity.

Function Achieved in This Case
The precooling device effectively maintains refrigerant temperature, preventing temperature rise-induced inefficiencies by precooling the refrigerant before it re-enters the CDU, thereby enhancing the CDU's cooling efficiency and maintaining optimal operating conditions.
Implementation Method 1
The refrigerant being performed the heat exchange returns through the flow joining row of the adapter assembly to the condensation area of the liquid cooling row for precooling

AI summary
A precooling device integrated with a cooling distribution unit and a server liquid cooling system are provided. The precooling device includes a liquid cooling row, an adapter assembly, and a cooling distribution unit. The adapter assembly includes a flow joining row and a flow distribution row. The cooling distribution unit supplies a refrigerant from an interior thereof, and includes an outlet and an inlet communicating with the interior. The outlet communicates with the flow distribution row of the adapter assembly to deliver the refrigerant for heat exchange. The refrigerant being performed the heat exchange returns to the liquid cooling row through the flow joining row of the adapter assembly for precooling, and then returns from the liquid cooling row to the cooling distribution unit through the inlet. The refrigerant is precooled before returning to the cooling distribution unit.
