Refrigeration Compressor Mounting Assembly for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration systems experience increased vibrations and noise due to directly welded brackets on the evaporator, leading to reduced service life and complex assembly processes, along with increased costs and insulation complexity.
Innovation Solution
A mounting assembly using elongated members and support brackets that are fastened to the tube sheets of the evaporator and condenser, allowing for the compressor to be mounted without direct welding, thereby reducing vibration transmission and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If brackets are directly welded to the evaporator shell to mount the compressor, then the mounting structure is simple and strong, but vibrations are directly transmitted between the evaporator and compressor, increasing noise and reducing service life
Solution Approach 1:
The patent introduces an intermediate mounting structure consisting of brackets attached to tube sheets rather than directly welding to the evaporator shell. This intermediary structure decouples the direct vibration path between compressor and evaporator, reducing harmful vibration transmission while maintaining mounting strength.
Solution Approach 2:
The mounting structure is segmented into separate components: brackets attached to tube sheets, and compressors mounted on these brackets. This segmentation separates the vibration sources and prevents direct transmission, while each component maintains its structural integrity.
2Strength
If brackets are welded to the evaporator shell, then the mounting is secure, but the assembling and dismantling processes become complex and time-consuming
Solution Approach 1:
The mounting structure transitions from a static welded connection to a dynamic, reconfigurable system using brackets and fasteners. This allows the mounting configuration to be easily adjusted, assembled, or disassembled without permanent modifications, reducing assembly time while maintaining security during operation.
3Ease of operation
If multiple brackets are positioned at different locations on the evaporator shell, then the compressor can be properly mounted, but the insulation of the evaporator shell becomes more complex
Solution Approach 1:
The tube sheets serve as intermediary mounting surfaces, positioned at the ends of the evaporator rather than requiring multiple brackets on the shell. This concentrates mounting points at specific locations, simplifying the insulation process on the evaporator shell while maintaining compressor mounting capability.
4Strength
If the welding process is used to mount brackets on the evaporator, then the mounting is permanent and strong, but the overall cost of the evaporator and refrigeration system increases
Solution Approach 1:
The patent replaces expensive welded brackets with more economical bracket components that can be attached using less costly fastening methods. While the brackets serve their purpose during system operation, they can be removed or replaced without the high costs associated with welding processes, reducing overall manufacturing costs.
