Abstract

The invention relates to a Stirling cooling arrangement (1) with a driving unit (2) generating periodically changing gas pressures, and a displacer unit (4) connected to the driving unit (2) and having a displacer that is movable along a displacer axis (26) in a displacer housing (16) and being guided in a cylinder (21). It is endeavoured to provide such a cooling arrangement with a simple design. For this purpose, the cylinder (21) is held unilaterally in the displacer housing (16).
