Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cooling systems in computer equipment face challenges with cooling liquid leakage due to poor connections, which can damage other electronic components.
Innovation Solution
A cold plate module is designed with a cold plate, a structural piece, a frame, and an absorbing element. The absorbing element is located between the entrance and exit of the inlet and outlet ports, respectively, to absorb any leaked cooling liquid, while the frame forms a complete enclosure to prevent further leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling liquid is used as a circulated medium to enhance heat dissipation, then the heat dissipation effect is improved, but the risk of cooling liquid leakage increases which may damage electronic components
Solution Approach 1:
The patent introduces an absorbing element (sponge) within the cold plate structure that acts as a buffer to absorb leaked cooling liquid before it can reach and damage electronic components. This beforehand cushioning measure is integrated into the cold plate design, allowing the system to maintain effective heat dissipation while having built-in protection against leakage damage.
2Object-affected harmful factors
If the absorbing element is added to prevent cooling liquid leakage damage, then the protection of electronic components is improved, but the device complexity increases
Solution Approach 1:
The absorbing element is integrated within the cold plate structure itself, merging the heat dissipation function and the leakage protection function into a single unified component. The sponge is positioned within the liquid storage space of the cold plate, eliminating the need for separate protection mechanisms and reducing overall system complexity.
Solution Approach 2:
The cold plate structure is designed to serve multiple functions: it provides heat dissipation through the circulating cooling liquid, stores excess cooling liquid in its liquid storage space, and uses the integrated absorbing element to prevent leakage damage. This multi-functionality reduces the need for additional separate components.
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 solution effectively prevents cooling liquid from leaking onto other electronic components, reducing the risk of damage and providing additional protection even when the absorbing element becomes saturated.
Implementation Method 1
The absorbing element is at least partially located between the fourth surface and both of the entrance and the exit... effectively prevents cooling liquid from leaking onto other electronic components
