Zusammenfassung: | To provide a pulse tube refrigeration machine having a rectifier in which rectification effect and/or heat exchange efficiency are improved.SOLUTION: A pulse tube refrigeration machine 10 comprises a pulse tube having an internal space, and an integrated rectifier 32 arranged at a low-temperature end and/or high-temperature end of the pulse tube. The integrated rectifier 32 comprises: a rectifying layer 32a arranged to face the internal space so as to rectify refrigerant gas flow from the internal space or into the internal space; and a heat exchange layer 32b integrally formed with the rectifying layer 32a outside the rectifying layer 32a with respect to the internal space so as to exchange heat with the refrigerant gas flow due to contact with the refrigerant gas flow. The rectifying layer 32a comprises a plurality of protrusions protruding from the heat exchange layer 32b toward the internal space.SELECTED DRAWING: Figure 1
【課題】整流効果及び/または熱交換効率に関して改良された整流器を有するパルス管冷凍機を提供する。【解決手段】パルス管冷凍機10は、管内空間を有するパルス管と、パルス管の低温端及び/または高温端に配置された一体型整流器32と、を備える。一体型整流器32は、管内空間から又は管内空間への冷媒ガス流れを整流するように管内空間に面して配置された整流層32aと、冷媒ガス流れとの接触により冷媒ガス流れと熱交換するように管内空間に対して整流層32aの外側に整流層32aと一体形成された熱交換層32bとを備える。整流層32aは、熱交換層32bから管内空間に向けて突出する複数の突起を備える。【選択図】図1 |
