<p>A gas wave refrigerator comprises a machine body (1), bearings (50, 52), a rotating wheel distributor (2), a sealing structure (3) and a receiving tube (4). The machine body (1) is provided with a gas inlet (162) and a gas outlet (142), and the sealing structure (3) is mounted between the gas inlet (162) and the gas outlet (142) on the machine body. The receiving tube (4) is inserted into a receiving tube interface (144) provided on the machine body (1); The sealing structure (3) comprises a rotary ring (31) which can rotate together with the rotating wheel distributor (2), and a stationary ring (32) which can not rotate together with the rotating wheel distributor (2) but can slightly move axially relative to the rotating wheel distributor (2) and the rotary ring (31). The stationary ring (32) is arranged adjacent to the rotary ring (31); A shell (47) surrounds the external of the receiving tube (4) and forms a cooling chamber (472). The gas wave refrigerator improves the sealing effect and the refrigerating efficiency of the refrigerator, reduces manufacturing and assembling difficulty.</p> |
