Spiral Bubble Concentrator for Liquid Cooling Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-cooling systems in computers face inefficiencies due to the presence of bubbles in pipelines, which slow down heat dissipation and can lead to cavitation, reducing the service life of components and hindering effective heat exchange.
Innovation Solution
An apparatus with a bubble elimination structure and a spiral structure is integrated into the liquid delivery pipeline, where the spiral structure concentrates bubbles in the center of the liquid flow, allowing bubble breaking elements to efficiently reduce their size and number, thereby improving heat exchange efficiency and extending component lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic discharge valves are installed at the top of the pipeline to discharge bubbles, then the system structure is simple, but the bubbles cannot be effectively and timely reduced as they are dispersed into the cooling liquid
Solution Approach 1:
The patent employs a spiral structure that generates rotational flow in the liquid, creating a vortex that concentrates bubbles toward the center of the pipeline. This curved flow path enables more effective bubble collection and discharge compared to straight pipeline configurations
Solution Approach 2:
The invention introduces a radial dimension to bubble discharge by using the spiral structure to move bubbles from the pipeline walls toward the center axis, creating a three-dimensional bubble concentration effect that enhances discharge effectiveness
2Reliability
If cooling liquid is circulated for a long time to discharge bubbles from complex pipelines, then bubbles can be removed, but it consumes a lot of time and reduces system productivity
Solution Approach 1:
The spiral structure is installed in advance within the pipeline to continuously generate rotational flow that prevents bubble accumulation and facilitates their movement toward discharge points, enabling faster bubble removal without extended circulation time
3Device complexity
If bubbles remain in the pipeline, then the system structure remains simple, but thermal resistance increases and heat exchange efficiency decreases
Solution Approach 1:
The spiral structure creates rotational flow that prevents bubble accumulation in critical heat exchange areas, maintaining thermal efficiency without requiring complex pipeline redesign or additional active bubble removal systems
