Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid-cooling blocks are heavy, prone to shaking during liquid delivery, and occupy large space, making them laborious to install and difficult to arrange multiple units effectively in computer products.
Innovation Solution
A liquid-cooling block design featuring a reservoir with a flow-dividing channel and a thermally conductive sheet with fins, where the pump is positioned externally, allowing for flexible arrangement and reduced size, enabling multiple blocks to be connected freely for enhanced heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump is installed inside the liquid-cooling block casing, then the liquid-cooling block can deliver liquid, but the weight of the liquid-cooling block becomes relatively large and it is prone to shaking
Solution Approach 1:
The pump is extracted from the liquid-cooling block casing and installed externally. The casing is modified to have a pump installation cavity that can accommodate the pump externally, thereby reducing the weight of the liquid-cooling block itself while maintaining the liquid delivery function through the pump's external placement.
2Ease of manufacture
If the liquid-cooling block is designed with standard size and structure, then it can be manufactured easily, but it occupies large space and is not conducive to internal space design of computer products
Solution Approach 1:
The liquid-cooling block is segmented into modular components including the casing, thermally conductive sheet, and flow channels. The pump is separated as an external component. This segmentation allows for compact integration within computer products while maintaining ease of manufacturing for each individual component.
3Device complexity
If one liquid-cooling radiator is set corresponding to one liquid-cooling block, then the system is simple to design, but it is difficult to meet the arrangement requirements of multiple liquid-cooling radiators for one liquid-cooling block
Solution Approach 1:
The liquid-cooling block is designed with universal mounting interfaces and standardized connection ports that can accommodate multiple liquid-cooling radiators. The casing structure includes multiple radiator installation positions, allowing a single liquid-cooling block to support various radiator configurations while maintaining simple system design.
