Scroll Compressor Funnel Assembly for Stable Suction Conduit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors in climate-control systems face challenges in efficiently and reliably circulating working fluids, such as refrigerant or carbon dioxide, between indoor and outdoor heat exchangers, affecting the system's cooling and heating performance.
Innovation Solution
A compressor design incorporating an orbiting scroll and a non-orbiting scroll with a suction conduit, where the suction conduit is securely mounted between the upper and lower scroll pieces using a mounting flange and locating pins or lips, ensuring stable fluid communication and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction conduit is mounted to the non-orbiting scroll using conventional methods, then the compressor can circulate working fluid, but the suction conduit may become disengaged during operation, reducing reliability
Solution Approach 1:
The mounting flange is nested between the upper and lower scroll pieces, with locating pins inserted through aligned openings in both scroll pieces and the flange. This nested configuration secures the suction conduit to the non-orbiting scroll, preventing disengagement during compressor operation while maintaining structural integrity.
Solution Approach 2:
The locating pins act as intermediary elements that bridge the mounting flange and the scroll pieces. These pins physically connect the three components (upper scroll piece, lower scroll piece, and mounting flange), ensuring stable engagement of the suction conduit without requiring complex fastening mechanisms.
2Reliability
If the suction conduit is securely mounted between scroll pieces, then engagement stability improves, but assembly complexity increases
Solution Approach 1:
The non-orbiting scroll is divided into separate upper and lower scroll pieces that can be assembled around the suction conduit. The mounting flange with its openings is positioned between these segments, allowing the locating pins to pass through all components and secure the assembly. This segmentation enables a reliable connection while maintaining manufacturability through modular assembly.
3Device complexity
If conventional mounting methods are used, then device complexity is low, but the suction conduit may disengage affecting fluid circulation
Solution Approach 1:
The compression mechanism utilizes spiral wraps with curved geometries that mesh together between the orbiting and non-orbiting scrolls. This curved design creates progressive compression chambers that efficiently circulate working fluid. The mounting structure integrates with this curved architecture, with the suction conduit positioned to align with the spiral geometry for optimal fluid flow.

AI summary
A compressor (10) may include an orbiting scroll (70), a non-orbiting scroll (72), and suction conduit (30). The non-orbiting scroll (72) is meshingly engaged with the orbiting scroll (70) and includes a lower scroll piece (86) and an upper scroll piece (94) that is mounted to the lower scroll piece. The suction conduit (30) is mounted to the non-orbiting scroll (72). The suction conduit includes an inlet (138), an outlet (138), and a mounting flange (132). The outlet is disposed adjacent to and in fluid communication with a suction inlet (89) of the non-orbiting scroll (72). At least a portion of the mounting flange (132) is captured between the upper (94) and lower (86) scroll pieces.
