[Patent Abstract]

The present invention discloses a structure and manufacturing method of a single linear compressor driving U-shaped and coaxial pulse tube cold fingers. The structure comprises a main base, a secondary base, a dual-pass compressor base, an opposed linear compressor main components, a compressor left casing, compressor right casing, upper compressor connecting tubes, 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, and lower compressor 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 U-shaped and coaxial pulse tube cryocoolers, achieving a single linear compressor to simultaneously drive U-shaped 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.
