Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vapor-liquid phase fluid heat transfer techniques require a large heat exchange area and long heat transfer paths, leading to poor heat exchange efficiency due to the use of fans and conventional tube designs, which occupy internal space and hinder quick flow of the working medium.
Innovation Solution
A vapor-liquid phase fluid heat transfer module with a minimized heat exchange area and shortened heat transfer path, featuring an evaporator with a chamber, an evaporator tube body, a heat exchanger with a condensation section, and a heat sink tube body, where the heat exchanger is disposed on the condensation section of the evaporator tube body or stacked, allowing for quick heat transfer to the heat sink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fan and conventional tube body are used for heat dissipation, then the heat sink can be cooled, but the heat exchange area becomes larger and the heat transfer path becomes longer, occupying more internal space and reducing heat exchange efficiency
Solution Approach 1:
The patent applies phase change technology by using a working medium that evaporates in the evaporator section and condenses in the condensation section. This phase transition mechanism enables highly efficient heat transfer without requiring fans or large heat exchange areas, directly resolving the contradiction between heat exchange efficiency and space occupation
Solution Approach 2:
The heat transfer system is segmented into distinct functional sections: evaporator section, condensation section, and adiabatic section. This segmentation allows each component to perform its specific function efficiently, with the phase change occurring in controlled locations, thereby reducing the overall space required while maintaining high heat exchange efficiency
2Productivity
If a conventional tube body with long heat transfer path is used, then the evaporator and heat sink can be connected, but the working medium cannot flow back quickly, leading to poor heat exchange efficiency
Solution Approach 1:
The patent introduces dynamic flow control mechanisms including capillary structures and throttling devices that adapt the flow characteristics of the working medium. This enables quick flow back of the condensed liquid to the evaporator without requiring long heat transfer paths, resolving the contradiction between heat exchange efficiency and path length
Solution Approach 2:
The system is designed with preliminary action by positioning the condensation section immediately adjacent to the evaporator section, and pre-configuring the flow return path through capillary wicking structures. This allows the working medium to quickly return to the evaporator without traversing a long path, maintaining high heat exchange efficiency
