Cooling Member With Absorbing Member For Refrigerant Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling members with sheet members and refrigerant face reduced cooling efficiency due to refrigerant remaining in expanded sections after evaporation, as the refrigerant in a liquid state does not effectively participate in heat transfer.
Innovation Solution
Incorporating a condensation section within the enclosing member with an absorbing member attached to its lower inner surface, ensuring that gaseous refrigerant is condensed and absorbed, preventing liquid refrigerant from remaining in expanded sections and enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the refrigerant is evaporated to improve cooling performance, then the pressure within the enclosing member increases and the sheet members are expanded, but the refrigerant that is in a liquid state may remain in the expanded sheet members and cooling properties are lowered
Solution Approach 1:
The enclosing member is divided into a condensation section and an expansion section. The condensation section is where the refrigerant condenses from gas to liquid, while the expansion section is where the sheet members expand when the refrigerant evaporates. This segmentation allows liquid refrigerant to be directed away from the expansion section, preventing it from remaining in areas where it cannot contribute to cooling performance.
Solution Approach 2:
The patent introduces a vertical dimension to the refrigerant flow path by positioning the condensation section at a higher location than the expansion section. When the refrigerant condenses, gravity causes the liquid to flow downward to a collection area, separating it from the expanded sheet members in the expansion section. This dimensional arrangement ensures that liquid refrigerant does not remain in the expansion section where it would be ineffective for cooling.
2Reliability
If a pipe is used to enclose the heat transfer fluid in a liquid tight manner, then the heat transfer fluid can be contained, but the pipe must be strong to withstand pressure increase when the fluid evaporates, increasing manufacturing cost
Solution Approach 1:
The patent replaces the rigid, strong pipe with flexible sheet members that are connected to form the enclosing member. These sheet members can expand when the refrigerant evaporates and pressure increases, eliminating the need for expensive, high-strength piping. The flexible nature of the sheet members allows them to accommodate pressure changes without requiring complex reinforcement or thick walls.
Solution Approach 2:
The enclosing member is segmented into different functional sections: a condensation section for refrigerant condensation, an expansion section that accommodates sheet member expansion, and a collection area for liquid refrigerant. This segmentation allows each section to be optimized for its specific function while using cost-effective sheet material rather than expensive strong piping throughout the entire structure.
