Integrated Liquid Cooling Distributor With Return-Line Precooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerant-type cooling distribution units (CDU) face the challenge of temperature rise due to heat exchange with external electronic components, necessitating re-cooling of refrigerant before it returns, which affects the CDU's ability to maintain low temperatures.
Innovation Solution
A precooling device integrated with a cooling distribution unit and server liquid cooling system, utilizing a liquid cooling row, adapter assembly, and cooling distribution unit to precool refrigerant before it returns to the CDU, via a condensation area and adapter assembly, ensuring refrigerant remains at low temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling distribution unit delivers refrigerant for heat exchange with external electronic components, then cooling performance is achieved, but the refrigerant temperature rises and requires re-cooling
Solution Approach 1:
The liquid cooling row is positioned to receive refrigerant from the CDU outlet and precool the returning refrigerant before it re-enters the CDU through the inlet. This preliminary cooling action occurs in the condensation area where the liquid cooling row facilitates heat exchange with the returning refrigerant, reducing its temperature before re-entry into the CDU.
2Temperature
If the refrigerant is cooled by the CDU to maintain low temperatures, then temperature control is achieved, but the system complexity increases
Solution Approach 1:
The liquid cooling row is integrated with the CDU structure, where the condensation area of the liquid cooling row serves as the precooling chamber. The adapter assembly connects the flow distribution side and flow joining side of the liquid cooling row to the CDU outlet and inlet respectively, merging the precooling function into the existing CDU architecture rather than adding a separate cooling system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The precooling device effectively maintains refrigerant at low temperatures by precooling it before it re-enters the CDU, thereby preventing temperature rise and ensuring efficient cooling performance.
Implementation Method 1
the refrigerant delivered by the CDU undergoes heat exchange with other external electronic components
Implementation Method 2
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.
