Title:
STIRLING REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2021/033890
Kind Code:
A1
Abstract:
A Stirling refrigerator according to an embodiment of the present invention can ensure a lower bending stiffness by comprising a displacer rod and a sealing guide partially surrounding the displacer rod. Further, the Stirling refrigerator can minimize friction by ensuring a hollow portion in a compression piston and appropriately selecting the length of the sealing guide which comes in direct contact with a through-hole. The Stirling refrigerator may further comprise a compensation part configured to compensate for misalignment between the displacer piston, the compression piston, the displacer rod, and the cylinder or bending of the displacer rod. The compensation part may comprise a ball joint, a link, a wire, a resin, a spring, etc. The ensured low bending stiffness and the minimized friction can reduce the precision and manufacturing time required for axial alignment in the manufacturing process. In addition, the refrigeration efficiency of the Stirling refrigerator can also be increased.
