Solution Overview
Problem
The existing air conditioner systems for vehicles have complex pipe layouts due to separate air cooling and water cooling condensers, leading to increased production costs and reduced performance due to refrigerant pressure drop.
Innovation Solution
An integral condenser system where the water cooling and air cooling regions are formed on a single plate, allowing for one-time brazing coupling of existing air cooling and water cooling condensers, simplifying assembly and reducing package size by integrating refrigerant and coolant flow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air cooling and water cooling condensers are used, then heat exchange efficiency is improved, but device complexity and production cost increase due to complex pipe layouts and multiple components
Solution Approach 1:
The patent combines the air cooling condenser and water cooling condenser into a single integrated condenser unit. The condenser includes both air cooling channels and water cooling channels formed in the same heat exchange plate, allowing both cooling functions to be performed by one component instead of requiring separate condensers and complex pipe connections.
Solution Approach 2:
The integrated condenser serves multiple functions simultaneously - it can operate as an air cooling condenser, a water cooling condenser, or both together. The heat exchange plate is designed with multiple channels that can handle different refrigerant flows for different cooling modes, making the single component universal for various operating conditions.
2Reliability
If separate air cooling and water cooling condensers are used, then cooling performance is maintained, but manufacturing cost increases due to additional assembly steps and brazing operations
Solution Approach 1:
The patent integrates both cooling functions into a single manufactured component - the heat exchange plate. This eliminates the need to assemble and braze multiple separate condenser units together, reducing manufacturing complexity while maintaining the cooling performance of both systems.
3Reliability
If separate condensers are used with complex pipe connections, then heat exchange capacity is sufficient, but refrigerant pressure drop increases reducing system performance
Solution Approach 1:
By merging both cooling functions into one condenser unit with internally integrated channels, the patent eliminates long external pipe connections and multiple bends. The refrigerant flows through channels within the same plate structure, significantly reducing pressure drop while maintaining adequate heat exchange capacity through properly designed channel geometries.

Implementation Method 2
an air cooling region heat-exchanging the refrigerant with air to condense the refrigerant
Implementation Method 3
an actual cooling action is generated by an evaporator in which a liquid-phase heat exchange medium is vaporized by absorbing an amount of heat corresponding to heat of vaporization from the surrounding
Implementation Method 4
A gas-phase heat exchange medium introduced from the evaporator into a compressor is compressed at a high temperature and a high pressure in the compressor
