Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat generating body box housing refrigeration devices face inefficiencies in refrigerant circulation and heat exchange due to the diagonal placement of refrigerant pipes, which increases circulation resistance and degrades refrigerant circulation and heat exchange efficiency.
Innovation Solution
The proposed solution involves a configuration with multiple refrigerant cycles, where first and second condensers and evaporators are vertically disposed with specific pipe connections to compensate for the degradation in refrigerant circulation and heat exchange efficiency, including the use of inclined and parallel arrangements of condensers and evaporators, and strategically placed pipe connections to enhance heat transfer.

Engineering Contradiction Analysis
1Volume of moving object
If refrigerant pipes are diagonally placed to connect evaporator and condenser, then the refrigeration device can be compact, but circulation resistance increases and refrigerant circulation efficiency degrades
Solution Approach 1:
The refrigerant circulation system is divided into multiple independent cycles (first refrigerant cycle and second refrigerant cycle), each with separate liquid pipes and steam pipes. This segmentation allows each cycle to have optimized pipe layouts that minimize circulation resistance while maintaining compact overall dimensions.
Solution Approach 2:
Different pipe connection configurations are applied to different cycles based on their specific requirements. The first cycle uses one diagonal pipe arrangement while the second cycle uses another, optimizing local refrigerant flow characteristics for each cycle while maintaining compact installation space.
2Volume of moving object
If refrigerant pipes are diagonally placed to reduce installation space, then compactness is achieved, but heat exchange efficiency degrades
Solution Approach 1:
The heat exchange system is segmented into multiple refrigerant cycles, allowing optimization of heat exchange performance in each cycle while maintaining compact overall dimensions. Each cycle can be independently configured for optimal heat transfer.
Solution Approach 2:
The invention changes the operational parameters of the refrigerant cycles, specifically the circulation rates and flow distributions in different cycles, to optimize heat exchange efficiency while maintaining compact pipe layouts.
