Liquid Immersion Tank Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for electronic devices struggle to accurately adjust the amount of refrigerant based on the heat generated by components, leading to inefficient cooling and refrigerant wastage, as they often scatter refrigerant in areas where it is not needed and fail to tailor the cooling to specific heat-generating components.
Innovation Solution
A liquid immersion tank system with a gutter and flow rate adjuster that directs refrigerant flow based on the heat generation of components, using a down-flow block with adjustable inclined surfaces to focus refrigerant flow on heat-generating components, and a flow rate adjusting gate to control refrigerant outflow, ensuring efficient cooling and minimizing refrigerant usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If refrigerant is sprayed or sprinkled using existing cooling systems, then cooling coverage is achieved, but refrigerant scatters in areas where it is not needed and cooling efficiency decreases
Solution Approach 1:
The patent implements local quality by providing different flow path configurations for different regions. The gutter structure directs refrigerant flow specifically toward heat-generating components based on their thermal characteristics, ensuring refrigerant is delivered precisely where needed rather than being uniformly scattered throughout the housing.
Solution Approach 2:
The flow path is segmented into multiple controlled channels through the gutter structure, allowing independent control of refrigerant distribution to different heat-generating components. This segmentation enables precise targeting of refrigerant flow to specific thermal zones within the housing.
2Adaptability or versatility
If existing cooling systems are used without flow control, then system simplicity is maintained, but the ability to adjust refrigerant flow based on heat generation is lost
Solution Approach 1:
The gutter structure is designed to automatically direct refrigerant flow based on gravity and pressure gradients, eliminating the need for complex active flow control mechanisms. The system self-regulates refrigerant distribution to heat-generating components through its geometric design, maintaining simplicity while achieving adaptability.
