Disclosed in the present invention is a Stirling refrigerator, comprising a housing, a piston, an ejector, an outer fixing assembly, and an inner fixing assembly. The piston and the ejector are both mounted in the housing; the ejector is located on one side of the piston; a shaft hole is formed in the middle of the piston; a connecting rod is connected to the end of the ejector close to the piston; the connecting rod passes through the shaft hole to expose outside the piston; the outer fixing assembly comprises an electromagnet core and an excitation coil wound around the electromagnet core; a piston spring is connected to the end of the piston distant from the ejector; the piston spring is fixedly connected to the housing; an ejector spring is connected to the end of the connecting rod exposed outside the piston; the ejector spring is fixedly connected to the housing; the ejector spring is located in the piston spring and coaxial with the piston spring; and the electromagnet core is coaxially sleeved outside the housing. The Stirling refrigerator is simple in structure, convenient to manufacture, low in cost, good in heat dissipation effect, and long in service life, and has relatively good coaxiality of a piston plate spring and an ejector plate spring and relatively high product percent of pass.
