AI Technical Summary
Existing air-wave refrigerators suffer from poor sealing, leading to high-pressure gas leakage, reduced cooling efficiency, and potential operational malfunctions such as vibration and whistling.
The contact-sealed inverted wave refrigerator utilizes a contact-sealing assembly of a stationary sealing ring and a dynamic sealing ring. The dynamic sealing ring and the stationary sealing ring are kept in close contact by spring preload, achieving dynamic sealing and preventing gas leakage. The inverted structure design also optimizes gas flow.
It effectively prevents gas leaks, ensures the stability and safety of equipment operation, improves refrigeration efficiency, reduces maintenance frequency, adapts to installation in confined spaces, and enhances environmental adaptability.
