[Patent Abstract]
The present invention discloses a compact structure and manufacturing method of a coaxial pulse tube cryocooler coupled with infrared devices. The structure comprises a main base, a compressor, connecting tubes, a phase shifter, a T-shaped heat dissipation support platform, a main heat exchanger, a secondary heat exchanger, a regenerator, a pulse tube, a cold-end heat exchanger, infrared devices, a cold shield, a Dewar, and a Dewar window. The coupling structure of this invention can fully utilize the structural advantages of coaxial pulse tube cryocoolers, achieving compactness and high reliability of the system. It has positive significance for the practical application of coaxial pulse tube cryocoolers in cooling infrared devices.
