Abstract

Stirling cooling arrangement with a driving unit (2) having a housing (47-49) and at least one piston (5, 6) that is driven by a linear motor (8, 9) along a piston axis (7) in a cylinder (29), and a displacer unit (3) that is connected to the driving unit (2) via a gas-carrying connection (24) and comprises at least one displacer (14) that is movable in a displacer housing (15) along a displacer axis (16), the linear motor (8, 9) comprising an armature (10, 11) that is connected to the piston (5, 6) and arranged between an inner stator (31 ) and an outer stator (32), and a coil arrangement (35, 35'). It is endeavoured to achieve a good efficiency. For this purpose, in the radial direction the coil arrangement (35, 35') is arranged inside the armature (10, 11).
