A mounting assembly for a refrigeration system
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/dismantling processes, especially in tight spaces, with elevated costs and insulation challenges.
Innovation Solution
A mounting assembly featuring elongated members and support brackets that transfer vibrations from the compressor to the evaporator, eliminating direct welding and simplifying the assembly process, while reducing noise and cost through the use of fasteners and modular design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If brackets are directly welded to the evaporator shell to mount the compressor, then the compressor can be securely mounted, but vibration transmission between the evaporator and compressor increases substantially
Solution Approach 1:
The patent introduces an intermediary mounting bracket assembly that mediates between the evaporator and compressor. The bracket is welded to the evaporator shell while the compressor is mounted to the bracket, creating a decoupling effect that reduces direct vibration transmission. The bracket acts as a vibration isolator by providing a separate mounting interface that doesn't directly couple the two vibrating components.
Solution Approach 2:
The mounting structure is segmented into separate components: the evaporator shell, the mounting bracket, and the compressor. Instead of directly coupling the compressor to the evaporator, the bracket is separated as an independent mounting element. This segmentation allows each component to be optimized independently and reduces the direct transmission path for vibrations.
2Strength
If brackets are welded directly to the evaporator shell, then secure mounting is achieved, but the assembling and dismantling processes become complex and cumbersome
Solution Approach 1:
The mounting system is divided into modular segments: the bracket that attaches to the evaporator and the compressor that attaches to the bracket. This segmentation allows the bracket to be pre-installed on the evaporator, and the compressor to be separately mounted, facilitating easier assembly and disassembly compared to direct welding of the compressor to the evaporator shell.
Solution Approach 2:
The mounting arrangement provides dynamic flexibility by allowing the compressor to be mounted to and dismounted from the bracket. This enables maintenance and replacement operations without requiring complex cutting or heating processes, as the compressor can be detached from the bracket and reattached as needed.
3Strength
If multiple brackets are positioned at different locations on the evaporator shell to mount the compressor, then secure mounting is achieved, but the complexity of insulating the evaporator shell increases
Solution Approach 1:
The mounting brackets are merged or consolidated into a single integrated mounting structure that attaches to the evaporator shell at one location. This consolidated bracket assembly provides multiple mounting points for the compressor while maintaining a unified attachment interface to the evaporator, thereby reducing the number of separate penetration points required in the insulation and simplifying the insulation process.
4Strength
If the welding process is used to mount brackets on the evaporator, then secure attachment is achieved, but the overall cost of the evaporator and refrigeration system increases
Solution Approach 1:
The mounting bracket serves as an intermediary component that reduces the need for expensive welding operations. Instead of welding the compressor directly to the evaporator shell, the bracket is welded to the evaporator while the compressor is mechanically attached to the bracket. This reduces welding requirements and associated costs while maintaining secure attachment.
