摘要： In a Stirling refrigerator, a regenerator has a low-temperature end and a high-temperature end. A plurality of protrusions, which thermally contact with the low-temperature end of the regenerator, are formed on a low-temperature heat exchanger. The low-temperature heat exchanger has a recess between the protrusions, and the recess forms a flowing groove through which a working gas flows. The regenerator may contain a mesh regenerator material.

摘要： In a Stirling cryocooler, a displacer includes an internal space which is filled with gas. The displacer is reciprocatably accommodated in the expander main body. The displacer accommodates in the internal space one or more convection control plates, for controlling gas convection to a minimum. The one or more convection control plates are disposed along a line intersecting the displacer's longitudinal axis. At least one of the convection control plates divides the internal space into first and second sub-chambers, and includes an opening through which the sub-chambers communicate. The at least one of the convection control plates includes a convection control wall provided in the opening.
