Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fan or ventilation openings are used for heat dissipation, then the heat dissipation function is provided, but the heat dissipation efficiency is poor and the fan surface accumulates dust
Solution Approach 1:
The patent extracts the fan component from the heat dissipation system and replaces it with a natural convection structure. The heat dissipation function is achieved through ventilation openings and convection channels that allow air to flow naturally from the interior to the exterior of the refrigerator van, eliminating the need for mechanical fans and their associated maintenance issues.
Solution Approach 2:
The heat dissipation system is designed to operate autonomously using natural convection currents. The convection channels and ventilation openings create a self-sustaining air flow that draws hot air from the interior components to the exterior without requiring external power or mechanical assistance, making the system self-service and maintenance-free.
2Reliability
If an additional cooling system with heat exchanger, pump device, and fan is added, then high heat exchange efficiency is achieved, but the system becomes expensive and occupies large installation space
Solution Approach 1:
The patent merges the heat dissipation function directly into the existing refrigerator van structure by integrating convection channels into the walls and utilizing the existing ventilation system. This eliminates the need for separate heat exchangers, pump devices, and fans, thereby reducing installation space while maintaining effective heat exchange through the combined structure.
Solution Approach 2:
The ventilation openings and convection channels serve multiple functions: they provide heat dissipation for internal components, enable natural air circulation within the van, and eliminate the need for separate cooling systems. This multi-functionality reduces the overall space requirement while achieving the desired heat exchange efficiency.
3Reliability
If an additional cooling system with pump device and heat exchanger is added, then high heat exchange efficiency is achieved, but the structure becomes complex and expensive
Solution Approach 1:
The patent removes complex components such as pump devices, heat exchangers, and fans from the cooling system. Instead, it utilizes the existing refrigerator van structure with integrated convection channels and ventilation openings to achieve heat dissipation through natural convection, thereby simplifying the system structure while maintaining effectiveness.
Solution Approach 2:
The cooling system operates autonomously using natural convection currents generated by temperature differences. The convection channels and ventilation openings create self-sustaining air flow that eliminates the need for mechanical pumps or fans, making the system self-service and significantly reducing structural complexity and cost.

Implementation Method 1
the heat exchange container receives liquid refrigerant from the reservoir through the flow pipe, the liquid refrigerant in the heat exchange container generates vapor after heat exchange with the heat absorbed from the high-temperature components
Implementation Method 2
the heat exchange container is located below the reservoir... the vapor enters the reservoir through the flow pipe, thus forming a circulation loop
