AI Technical Summary

Technical Problem

The fluid exchange system of the existing room temperature magnetic refrigerator is composed of five solenoid valves, which leads to high noise, high heat generation, large volume and low reliability, which limits its integrated, miniaturized, lightweight and silent design.

Method used

Design a converter valve for room temperature magnetic refrigeration machine. By integrating multiple solenoid valve functions into a rotating valve, the valve core rotates under the drive gear to realize the opening and closing functions of multiple solenoid valves, using ceramic material and ring shape The valve core recess structure ensures sealing of the fluid passages and efficient conversion.

Benefits of technology

It achieves a simple structure, small size, high degree of integration, no noise during the conversion process, and basically no heat generated during operation, which improves the temperature span and practicality of the magnetic refrigerator.
