Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices face challenges in efficiently transporting liquid-phase refrigerant from transport pipes to evaporators due to blockage issues when the transport pipe and evaporator structures are directly joined, hindering effective heat dissipation and refrigerant circulation.
Innovation Solution
The cooling device incorporates gap generators, such as inclined portions on the transport pipes, to create gaps between the transport pipes and the evaporator, allowing for the free movement of liquid-phase refrigerant and enhancing capillary action, while also using a vessel structure with support columns and fins for efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transport pipe and evaporator are directly joined, then the structure is simple, but the liquid-phase refrigerant cannot move freely from the transport pipe to the evaporator
Solution Approach 1:
The invention divides the connection between transport pipe and evaporator into separate components by introducing a gap generator, allowing the refrigerant to transition through a defined gap rather than requiring direct contact between components
Solution Approach 2:
The gap generator acts as an intermediary element between the transport pipe and evaporator, facilitating refrigerant flow from the transport pipe into the evaporator through a controlled gap space
2Temperature
If columnar members are densely arranged to increase heat dissipation surface area, then heat dissipation properties improve, but the structure becomes more complex
Solution Approach 1:
The invention combines the heat dissipation function with the structural support function by integrating columnar members that serve both as structural elements and as heat dissipation surfaces, reducing overall structural complexity
