Targeted Refrigerant Cooling Loop for Low-Refrigerant Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems require immersing the entire electronic device in refrigerant, leading to excessive refrigerant usage, which is costly.
Innovation Solution
A cooling device with a storage tank, refrigerant supply unit, and refrigerant cooling unit that pumps and recovers refrigerant, allowing for targeted refrigerant supply and heat exchange to reduce refrigerant usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the entire electronic device is immersed in refrigerant for cooling, then cooling effectiveness is improved, but refrigerant consumption increases
Solution Approach 1:
The cooling system is segmented into two independent loops: a primary loop with minimal refrigerant in a storage tank, and a secondary loop that delivers refrigerant to heat-generating components. This segmentation allows effective cooling without requiring large quantities of refrigerant throughout the entire device.
Solution Approach 2:
Refrigerant is selectively supplied to locations with high heat generation (such as CPU, GPU, or other heat-generating components) rather than immersing the entire device. This localised approach maintains cooling effectiveness while minimizing refrigerant consumption.
2Productivity
If a refrigerant circulation system is implemented, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The system employs passive mechanisms such as gravity-driven refrigerant return and natural convection to circulate refrigerant between the storage tank and heat-generating components, reducing the need for complex active pumping and control systems while maintaining cooling efficiency.
