Solution Overview
Problem
Conventional cooling systems experience reduced cooling efficiency due to non-uniform coolant flow rates, leading to coolant accumulation at certain ports, which affects heat transfer efficiency.
Innovation Solution
The cooling assembly features a cold plate with a housing and partitioning that separates the coolant flow path into distinct chambers, utilizing strategically placed through holes to ensure even coolant distribution and flow across multiple heat generating components, thereby reducing stagnation and enhancing heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single plate chamber with horizontal flow path is used, then the structure is simple, but coolant flow rate becomes non-uniform causing accumulation at confluence port and reduced cooling efficiency
Solution Approach 1:
The single plate chamber is divided into multiple plate chambers (first, second, third plate chambers) with separate through holes in the partition wall. This segmentation allows independent coolant flow paths for different heat generating components, preventing flow accumulation and ensuring uniform cooling across all components while maintaining structural simplicity through modular design.
2Ease of manufacture
If coolant flow path is horizontal with respect to heat generating component, then manufacturing is easier, but coolant accumulates at confluence port and cooling efficiency is lowered
Solution Approach 1:
Different plate chambers are configured with through holes at different positions and orientations relative to their respective heat generating components. This local customization of flow path characteristics ensures that each component receives adequate coolant flow despite the overall horizontal flow direction, preventing accumulation issues while maintaining ease of manufacture.

AI summary
A cooling assembly includes a cold plate in contact with a heat generating component, a housing on one side of the cooling assembly in a first direction with respect to the cold plate, a first wall located between the housing and the cold plate, and a second wall separating a plate chamber defined by the housing and the first wall into a first plate chamber and a second plate chamber adjacent to each other in a second direction orthogonal to the first direction. The first wall includes a first through hole opposing the cold plate in the first plate chamber and a second through hole opposing the cold plate in the second plate chamber.
