[Patent Abstract]

The present invention discloses a structure and manufacturing method of a single linear compressor driving linear and coaxial pulse tube cold fingers. The structure comprises a main base, a secondary base, a dual-pass compressor base, opposed linear compressor main components, a compressor left casing, a compressor right casing, an upper pulse tube hot-end heat exchanger, an upper main heat exchanger, an upper secondary heat exchanger, an upper regenerator, an upper pulse tube, an upper cold-end heat exchanger, an upper vacuum shell, upper pulse tube connecting tubes, an upper inertance tube, an upper gas reservoir, an upper protective shell, an upper lifting support, and compressor lower connecting tubes, a lower main heat exchanger, a lower secondary heat exchanger, a lower regenerator, a lower pulse tube, a lower cold-end heat exchanger, a lower vacuum shell, lower pulse tube connecting tubes, a lower inertance tube, a lower gas reservoir, and a lower protective shell. The present invention fully utilizes the structural characteristics of linear and coaxial pulse tube cryocoolers, achieving a single linear compressor to simultaneously drive linear and coaxial pulse tube cold fingers. The present invention has great significance for the practical application of pulse tube cryocoolers in space and other special fields.
