10). A Structure and Manufacturing Method of a Single Linear Compressor Driving Two Coaxial Pulse Tube Cold Fingers

[Patent Abstract]

This present invention discloses a structure and manufacturing method of a single linear compressor driving two 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 left compressor casing, a right compressor 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. This invention fully utilizes the structural characteristics of coaxial pulse tube cryocoolers, inertance tube phase shifters, and linear compressors to achieve the simultaneous driving of two coaxial pulse tube cold fingers by a single linear compressor. The present invention has great significance for the practical application of pulse tube cryocoolers in space and other special fields.
