Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cooling devices using phase change cycles, the accumulation of refrigerant liquid in tanks can lead to overflow into vapor pipes, hindering vapor flow and reducing heat transport efficiency, necessitating increased tank capacity to prevent overflow.
Innovation Solution
A gas-liquid separation device with a tank that stores refrigerant liquid on its lower surface and a floating regulating valve that closes the space between the tank and vapor pipe, preventing refrigerant liquid from flowing back into the vapor pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tank capacity is increased to prevent refrigerant liquid overflow, then reliability is improved, but device complexity and space requirements worsen
Solution Approach 1:
A regulating valve is introduced as an intermediary component between the tank and vapor pipe. The valve includes a float that rises with liquid level and a valve body that seals the vapor pipe opening, preventing refrigerant liquid from overflowing into the vapor pipe while maintaining a compact tank design.
Solution Approach 2:
The regulating valve changes its position parameter based on liquid level height. As the refrigerant liquid level rises, the float rises accordingly, moving the valve body to seal the vapor pipe opening, thus dynamically adapting to liquid level changes without requiring increased tank capacity.
2Volume of stationary object
If tank capacity is reduced, then device complexity and space requirements are improved, but reliability deteriorates due to potential liquid overflow
Solution Approach 1:
The regulating valve acts as a protective intermediary that enables the use of a smaller tank by actively preventing liquid overflow. The float-valve mechanism monitors liquid level and seals the vapor pipe connection when the liquid reaches a critical level, ensuring reliability despite reduced tank capacity.
3Stability of the object's composition
If refrigerant liquid accumulates in the tank, then gas-liquid separation is improved, but heat transport efficiency worsens due to potential overflow into vapor pipe
Solution Approach 1:
The regulating valve serves as a protective barrier that allows effective gas-liquid separation in the tank while preventing the harmful overflow of liquid into the vapor pipe. This maintains both good separation and high heat transport efficiency by blocking the overflow path at the vapor pipe opening.
