STIRLING COOLING ARRANGEMENT

摘要

The invention concerns a Stirling cooling arrangement (1) with a driving unit (2) that generates periodically changing gas pressures, and a displacer unit (4) that is connected to the driving unit (2) and comprises a displacer (11) that is movable in a displacer housing (6) along a displacer axis (29), said displacer (11) having differently large pressure application surfaces on its two end faces. It is endeavoured to achieve a good efficiency. For this purpose, the inside of the displacer (11) accommodates a sealing pipe (24) that extends from an end face and comprises at least one sealing element (25) that is connected to the displacer housing (6) and fills the cross-section of the sealing pipe (24).
