Scroll Compressor Main Frame Segmentation for Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scroll compressors face challenges in increasing refrigerant discharge amount within a predetermined casing size due to limitations in orbiting radius and compression chamber height, which reduces durability and rigidity.
Innovation Solution
The design incorporates a main frame with a thinner side plate that supports the orbiting scroll, allowing for an increased orbiting radius and maintaining axial compression chamber height, along with a flange insertion groove system for secure fastening, enhancing refrigerant discharge without compromising rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the orbiting radius is increased to increase refrigerant discharge amount, then the discharge amount is improved, but the durability and rigidity of the compression chamber deteriorate due to reduced structural support
Solution Approach 1:
The housing is divided into multiple components: center housing, front housing, and rear housing, which are assembled together. This segmentation allows the orbiting radius to be increased while maintaining structural integrity through proper distribution of structural support functions across different housing components.
Solution Approach 2:
The invention increases the orbiting radius in the radial dimension while maintaining the axial height of the compression chamber. This dimensional change allows the orbiting scroll to have a larger orbiting radius without increasing the axial length, thereby increasing refrigerant discharge amount while maintaining structural rigidity through the housing assembly.
2Productivity
If the axial height of compression chamber is increased to increase refrigerant discharge amount, then the discharge amount is improved, but the structural rigidity and durability deteriorate
Solution Approach 1:
Instead of increasing the axial height of the compression chamber, the invention increases the orbiting radius in the radial dimension. This allows the discharge amount to be increased while maintaining the axial height and thus preserving the structural rigidity and durability of the compression chamber.
3Adaptability or versatility
If the housing is assembled from multiple parts to accommodate larger components, then the adaptability is improved, but the leakage risk increases
Solution Approach 1:
Sealing members are introduced as intermediary components between the center housing, front housing, and rear housing to prevent leakage at the joints. These sealing members ensure that the segmented housing structure maintains sealing reliability while providing the adaptability to accommodate larger orbiting scroll configurations.

AI summary
A scroll compressor includes a casing; an orbiting scroll; a fixed scroll; and a main frame which supports the orbiting scroll. The fixed scroll may include a fixed scroll end plate and a fixed scroll wrap which protrudes from the fixed scroll end plate. The main frame may include a main frame end plate which is provided on the opposite side of the fixed scroll end plate on the basis of the orbiting scroll, and a main frame side plate which protrudes from an outer circumferential portion of the main frame end plate toward the fixed scroll. The fixed scroll end plate, the main frame end plate, and the main frame side plate may form an orbiting space of the orbiting scroll.
