[0002] The traditional rotary Stirling refrigerator mainly realizes the reciprocating linear motion of the compression piston and the push piston through the drive of the rotary motor and the transmission of the crank-link mechanism. The vertical distribution in space will cause the refrigerator to waste space in the system application, which is not conducive to the micro-integration of the system

The invention provides a stirling cryocooler. The stirling cryocooler comprises a base and a cold finger. A cold storage device is arranged in the cold finger. A closed cavityis defined by the base and the cold finger. A cam rotating part and a rotating motor are arranged in the base, and the rotating motor drives the cam rotating part to rotate. The outer wall of the cam rotating part comprises awavy matching surface which is arranged in the rotating direction of the cam rotating part. Multiple compression assemblies which synchronously work are arranged in the base and arranged around the matching surface. Each compression assembly comprises an air cylinder, a piston and a piston push rod. The piston push rods cooperate with the matching surface so that the pistons can doreciprocating movement in the air cylinders. The air cylinders communicate with the cold finger. According to the stirling cryocooler, the new transmission mode that the rotating movement of the rotating motor M isconverted into the reciprocating linear movement of the pistons is adopted, no crank and connecting rod mechanism needs to be arranged, the volume of a cooling agent is greatly reduced, and the miniaturization and the integration of the cooling agent are achieved. In addition, the compression assemblies are uniformly and oppositely distributed, and therefore the low vibration requirement of the cooling agent is met.
Description
technical field [0001] The invention relates to the field of refrigeration and cryogenic engineering, in particular to a Stirling refrigerator. Background technique [0002] The traditional rotary Stirling refrigerator mainly realizes the reciprocating linear motion of the compression piston and the push piston through the drive of the rotary motor and the transmission of the crank-link mechanism. If they are vertically distributed in space, the refrigerators will waste space in the system application, which is not conducive to the micro-integration of the system. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a Stirling refrigerator to realize low vibration, miniaturization and integration of the refrigerator. [0004] The present invention is achieved like this: [0005] The invention provides a Stirling refrigerator, which comprises a base and a cold finger. A cold accumulator is arranged ...
