Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing condenser designs for car air conditioners face challenges in maintaining stable condensation performance when reduced in size, particularly under varying external environmental conditions such as temperature and wind speed, due to insufficient condensation regions and increased heat exchange loads.
Innovation Solution
The proposed condenser incorporates a liquid receiving section with multiple spaces and throttles to separate refrigerant into gaseous and liquid phases, allowing for improved gas-liquid separation and pressure differences, which enhances the stability of condensation performance by preventing refrigerant accumulation and reducing the impact of environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the condenser size is reduced, then the layout restriction in the engine room is satisfied, but the condensation region becomes insufficient and condensation performance becomes unstable
Solution Approach 1:
The liquid receiving section is divided into multiple spaces (first space, second space, third space) with distinct functions. The first space receives refrigerant, the second space separates gas-liquid phases, and the third space directs liquid refrigerant to the super-cooling section. This segmentation allows efficient use of limited space while maintaining stable condensation performance through proper refrigerant flow management.
Solution Approach 2:
The liquid receiving section acts as an intermediary component between the condensation section and super-cooling section. It includes a throttle mechanism that creates pressure differences to prevent refrigerant accumulation in the condensation paths, thereby maintaining stable condensation performance even when the overall condenser size is reduced.
2Volume of moving object
If the condenser size is reduced, then the layout restriction is satisfied, but the heat exchange load increases
Solution Approach 1:
The invention changes the pressure parameters within the liquid receiving section by introducing a throttle mechanism. This creates pressure differences between the first space (higher pressure) and second space (lower pressure), enabling efficient refrigerant flow and heat exchange in a compact configuration, thereby managing increased heat exchange load in a reduced-size condenser.
3Volume of moving object
If the condenser size is reduced, then the layout restriction is satisfied, but refrigerant accumulation occurs in condensation paths
Solution Approach 1:
The liquid receiving section with its throttle mechanism serves as an intermediary that regulates refrigerant flow. By creating pressure differences, it prevents refrigerant accumulation in the condensation paths while maintaining proper refrigerant distribution in the reduced-size condenser configuration.
Solution Approach 2:
Different spaces within the liquid receiving section have different pressure qualities. The first space maintains higher pressure to receive refrigerant from the condensation section, while the second space has lower pressure to facilitate gas-liquid separation and prevent refrigerant accumulation in condensation paths.

AI summary
A condenser includes a condensation section, a super-cooling section, and a liquid receiving section. Refrigerant from heat exchange tubes of a first heat exchange path of the condensation section flows into those of a second heat exchange path through the liquid receiving section. The liquid receiving section includes a first space for receiving refrigerant from the heat exchange tubes of the first heat exchange path, a second space which is located above the first space and in which refrigerant from the first space is separated into gaseous and liquid phases, and a third space which is located below the first space, which receives refrigerant from the second space, and from which refrigerant flows to the heat exchange tubes of the second heat exchange path. A first partition member between the first space and the second space has a throttle for refrigerant flowing from the first space into the second space.
