Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regenerator is added to heat the refrigerant before the evaporator, then the refrigerant condensation problem is solved, but the system volume increases
Solution Approach 1:
The patent merges the regenerator function with the pump body by integrating a heat exchange chamber inside the pump housing. The pump casing serves dual purposes: as the pump structure and as the heating chamber for the refrigerant. This integration eliminates the need for a separate regenerator component, thereby preventing refrigerant condensation while maintaining compact system volume.
Solution Approach 2:
The pump casing is designed to perform multiple functions simultaneously: it houses the pump mechanism for circulating refrigerant and serves as a heating chamber (regenerator) that preheats the liquid refrigerant before it enters the evaporator. This multi-functionality resolves the contradiction by eliminating the need for a separate regenerator component.
2Object-affected harmful factors
If the liquid refrigerant temperature is too low, then condensation into water droplets occurs during transmission, but heating the refrigerant requires additional components
Solution Approach 1:
The patent combines the heating function with the pump structure by creating an integrated heat exchange chamber within the pump housing. Liquid refrigerant flows through this chamber where it is heated by the pump body before being pumped to the evaporator, preventing condensation without requiring separate heating components.
Solution Approach 2:
The pump body serves its own cooling needs while simultaneously providing heating service to the refrigerant. The heat generated by the pump motor and mechanical operation is utilized to preheat the liquid refrigerant in the integrated heat exchange chamber, creating a self-sufficient system that prevents condensation without external heating components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated system reduces volume, prevents condensation, and enhances cooling efficiency, reducing energy consumption, noise, and vibration while ensuring safe operation in narrow spaces.
Implementation Method 1
The liquid refrigerant flows into the preheating room through the pump outlet and touches the pump to exchange heat
Implementation Method 2
the refrigerant will not condense on the outer wall of the transmission pipe because the refrigerant has been heated by the circulating pump before entering the evaporation cooling plate to evaporate and absorb heat
Implementation Method 3
a condenser, a liquid storage tank, and a circularly preheating chamber, which are sequentially connected in a closed-loop
