Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-phase fluid heat transfer techniques require a large heat exchange area and a long heat transfer path, leading to poor heat exchange efficiency, especially in high heat flux applications.
Innovation Solution
A two-phase fluid heat transfer structure with a heat exchanger disposed on the condensation section of the evaporator tube body, allowing for a minimized heat exchange area and shortened heat transfer path, enhancing heat exchange efficiency by quickly transferring heat from the evaporator to the heat sink through a heat exchanger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional vapor tube and liquid tube are used for heat transfer, then the system structure is simple, but the heat transfer path is long so that the working medium can hardly quickly flow back, leading to poor heat exchange efficiency
Solution Approach 1:
The patent transforms the traditional linear heat transfer path into a three-dimensional integrated structure. The heat sink is positioned directly on the condensation section of the evaporator tube body, creating a vertical/stacked arrangement that dramatically shortens the heat transfer path while utilizing spatial dimensionality to optimize heat exchange efficiency
2Temperature
If a fan is used to cool the heat sink, then the heat dissipation function is achieved, but a larger heat exchange area is required which occupies more internal space of the system
Solution Approach 1:
The patent merges the heat sink with the condensation section of the evaporator tube body, creating an integrated heat exchange structure. This combination eliminates the need for separate cooling components like fans, reduces the overall heat exchange area required, and improves space utilization within the system
