Receiver Dryer Taper Joint for Lighter Condenser Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional receiver dryers for air conditioners have a complex construction with multiple parts, leading to increased size and weight, which complicates installation and reduces efficiency.
Innovation Solution
A simplified joint construction for the receiver dryer that eliminates the need for a closing member and connector bolts, using a taper-shaped joint with a hole for refrigerant passage, and a ring-shaped protruding portion or threads for secure fixation to the condenser, allowing for a thinner joint design similar to the body thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing member and connector bolts are used to join the receiver dryer to the condenser, then the connection is secure and reliable, but the number of parts increases, weight increases, and the installation construction becomes complex
Solution Approach 1:
The receiver dryer body and condenser are merged into a single integrated unit, eliminating the need for separate closing members and connector bolts. The joint portion is formed directly as part of the receiver dryer body through forging or extrusion, creating a unified structure that reduces part count while maintaining connection reliability.
Solution Approach 2:
The joint portion serves multiple functions simultaneously: it provides structural connection between the receiver dryer and condenser, acts as a mounting surface, and integrates the refrigerant passage. This multi-functionality eliminates the need for separate fastening components while maintaining secure connection.
2Reliability
If a closing member and connector bolts are used to join the receiver dryer to the condenser, then the connection is secure and reliable, but the weight of the receiver dryer increases
Solution Approach 1:
The receiver dryer body and condenser are merged into a single integrated unit, eliminating the need for separate closing members and connector bolts. The joint portion is formed directly as part of the receiver dryer body through forging or extrusion, creating a unified structure that reduces part count while maintaining connection reliability.
Solution Approach 2:
The unnecessary closing members and connector bolts are extracted/removed from the design. Only the essential joint portion remains, which is formed as an integral part of the receiver dryer body, thereby reducing overall weight while maintaining connection reliability.
3Strength
If a thick joint portion is used to threadedly connect the receiver dryer to the condenser, then the connection strength is sufficient, but the overall size of the receiver dryer increases
Solution Approach 1:
The receiver dryer body and condenser are merged into a single integrated unit, eliminating the need for separate closing members and connector bolts. The joint portion is formed directly as part of the receiver dryer body through forging or extrusion, creating a unified structure that reduces part count while maintaining connection reliability.
Solution Approach 2:
The joint portion thickness is optimized through parameter changes in the design. By adjusting the thickness parameter within acceptable ranges and using appropriate joining methods (such as integral forming or thin-welded structures), the connection strength is maintained while minimizing the volume occupied by the joint portion.

AI summary
A receiver dryer (10) for storing and drying a refrigerant for an air conditioner is integrally fixed to a condenser (1) to form an assembly. A condenser (1) has refrigerant flow passages (2, 3), and also has an opening portion (4) for assembling a receiver dryer(10). In a body (100) of the receiver dryer, a desiccant (120) and members such as a filter (130) are inserted. The refrigerant flows into the receiver dryer (10) from the flow passage (2) through a hole (112), and flows out to the outflow passage (3) side through a strainer (150). A ring-shaped protruding portion is formed on the body (100) by bulging, and the body (100) is fixed to the condenser (1) by a C ring.
