PROBLEM TO BE SOLVED: To provide a cooling device in which cooling medium can be stably circulated in a high temperature side heat carrying cycle in a Sterling freezer even when a cooling device is inclined. SOLUTION: The Sterling freezer is provided with a low temperature heat carrying cycle to take out cold heat generated at a low temperature part, and the high temperature side heat carrying cycle to emit hot heat generated at a high temperature part outward. The high temperature side heat carrying cycle is provided with a high temperature side evaporator installed on the high temperature part, and a high temperature side condenser disposed at a higher position than the high temperature side evaporator. The high temperature side evaporator and the high temperature side condenser are connected to each other by steam side cooling medium piping 7 and condensation side cooling medium piping to form a cooling medium circulation circuit. The condensation side cooling medium piping is provided with a lateral tube disposed at a higher position than the high temperature side evaporator for the high temperature side condenser to be connected, and a pair of vertical tubes connecting the high temperature side evaporator and the lateral tube to each other in vertical directions. Upper ends of the vertical tubes are respectively connected to one end part and the other end part of the lateral tube. COPYRIGHT: (C)2005,JPO&NCIPI
