Receiver-Integrated Condenser Filter Structure for Lower Weight Brazing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing receiver designs for refrigerant separation are heavy and costly due to the large internal thread component, which increases the heat mass and compromises the brazing properties between components, leading to reduced efficiency and increased production costs.
Innovation Solution
A receiver design with a cylindrical main tank, a smaller internal thread component, a cap with a male thread, and a filter portion that includes a net to collect foreign matter, reducing the axial dimension and weight of the internal thread component, and simplifying the assembly process by separating the internal thread component from the tank, thus reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the internal thread component is made with a large axial dimension to hold the cap and filter, then the structural stability is improved, but the weight and production cost increase
Solution Approach 1:
The internal thread component is divided into multiple sections: a thin-walled body portion that provides structural support, and a separate holding portion that secures the cap and filter. This segmentation allows the main body to have minimal wall thickness while maintaining overall structural stability through the distributed design of the holding features.
Solution Approach 2:
Instead of increasing the axial dimension of the internal thread component to hold the cap and filter, the patent utilizes radial extensions and protrusions from the component body. The holding portion extends radially outward to engage with the cap and filter assembly, transforming the problem from an axial dimension issue to a radial dimension solution, thereby reducing axial length and overall weight.
2Strength
If the internal thread component is made with large thickness to provide structural support, then the strength is improved, but the heat mass increases and brazing property deteriorates
Solution Approach 1:
The internal thread component separates structural support functions from joining functions. The thin-walled body provides sufficient structural strength for its purpose, while dedicated holding portions with appropriate thickness and geometry provide the strength needed for cap and filter retention. This segmentation allows optimized thickness at each location rather than uniform thick walls throughout, reducing overall heat mass and improving brazing properties.
Solution Approach 2:
The internal thread component features non-uniform wall thickness distribution: thinner walls in the main body where structural support requirements are lower, and localized thicker sections at the holding portion where strength is needed for securing the cap and filter. This local quality approach maintains necessary strength while minimizing overall heat mass and improving brazing characteristics.

AI summary
A receiver includes a cylindrical main tank; a cylindrical internal thread component having an internal thread; a cap having a male thread threaded with the internal thread; a sealing attached to the cap; and a filter portion arranged in the cap. The internal thread component is coaxially arranged to an inner circumference face of the tank. The filter portion includes an internal passage extending inside of the cap, and a net that collects a foreign matter contained in refrigerant flowing through the internal passage.
