Compressor Vibration Attenuating Structure for Discharge Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors face challenges in reducing vibration and noise, particularly at the refrigerant discharge side, as vibrations are transmitted to a larger mass frame, making it difficult to efficiently dissipate the total amount of vibration or noise generated during the refrigerant discharge process.
Innovation Solution
A vibration attenuating member is introduced, comprising a support structure with a spring wire and an isolating member like rubber or plastic, which connects the driving assembly to the shell, featuring a coil and attenuating portions to absorb and dissipate vibrations, thereby reducing noise and vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If vibration is transmitted to a larger mass frame, then vibration dissipation is improved, but total vibration and noise reduction is insufficient
Solution Approach 1:
The patent introduces a vibration attenuating member as an intermediary component between the driving assembly and the shell. This member includes a support portion that contacts the driving assembly and an attenuating portion that extends to the shell, acting as a mediator to reduce vibration transmission while preventing direct contact and temporary bias.
Solution Approach 2:
The patent extracts the vibration attenuation function from the frame structure and implements it through a separate, dedicated vibration attenuating member. This allows the frame to maintain its structural integrity while the specialized attenuating member handles vibration reduction through its elastic deformation capability.
2Object-generated harmful factors
If a vibration attenuating member is introduced, then vibration and noise reduction is improved, but device complexity increases
Solution Approach 1:
The vibration attenuating member is segmented into two functional portions: a support portion that contacts the driving assembly and an attenuating portion that extends to the shell. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural simplicity.
Solution Approach 2:
The patent utilizes parameter changes in the attenuating portion, specifically its elastic properties and geometric configuration, to achieve vibration attenuation. By adjusting the length, cross-section, and material properties of the attenuating portion, effective vibration reduction is achieved without complex mechanisms.
