Abstract

The invention relates to a flexible supporting system for a suspension of a refrigerating machine, the problem that the axial vibration of the refrigerating machine is large when the existing linear refrigerating machine works, and the requirements of the infrared focal plane cooling, the lens cooling and germanium detector on the vibration index requirements cannot be met is solved. Based on therefrigerating machine, the refrigerating machine is suspended in a bracket, the bracket is a hollow frame; the tail part of the refrigerating machine is fixedly connected with a passive vibration absorber. Compared with a traditional refrigerating machine fixed clamping mode, the external vibration output of the refrigerating system is effectively reduced, the resonance problem generated by the refrigerating machine and the system is well solved, the system is suitable for the fields of aerospace infrared detectors, germanium detectors and cold electronics with refrigerating machines as cold sources.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a suspension flexible support system for refrigerators. Background technique [0002] Infrared detection systems based on infrared focal plane arrays are widely used in the aerospace field, such as spaceborne early warning systems, satellite remote sensing predictions, geological resource surveys, disaster assessments, atmospheric environment monitoring, ground reconnaissance, search and tracking, satellite navigation, missile guidance, Real-time precision strikes and monitoring of complex background, sea and sky changes, etc. However, the large volume and weight of the pulse tube refrigerator and low reliability are the biggest bottlenecks restricting its development; germanium detectors have extremely high requirements for micro-vibration (cold finger vibration), and the demand for cooling capacity is large, and the current pulse tube refrigerator is far from It cannot m...
