Zusammenfassung:	To provide a cooling device using an air refrigerant cycle that can maintain a stable cooling efficiency for a long term without being influenced by frost adhering to an inside of piping.SOLUTION: A cooling device 1 uses an air refrigerant cycle in which a compressor C for compressing air collected from a chamber to be cooled 2, heat exchangers 3, 4 for cooling the air compressed by the compressor C, and an expander E for expanding the air cooled by the heat exchangers 3, 4 are connected by pipes 7a-7 m. The cooling device is provided with jet flow generating parts 23, 24, 7d, 5 for jetting compressed air toward the inside of a piping member 22 which is located downstream of the expander E.SELECTED DRAWING: Figure 2 【課題】配管内部に付着する霜の影響を受けることなく、長期に亘り安定した冷却効率を維持することのできる空気冷媒サイクルを用いた冷却装置を提供する。【解決手段】被冷却室２から回収した空気を圧縮する圧縮機Ｃと、圧縮機Ｃにより圧縮された空気を冷却する熱交換器３，４と、熱交換器３，４により冷却された空気を膨張させる膨張機Ｅとが配管７ａ〜７ｍにより接続された空気冷媒サイクルを用いた冷却装置１であって、膨張機Ｅの下流側の配管部材２２の内部に向け圧縮空気を噴出させる噴流発生部２３，２４，７ｄ，５が設けられている。【選択図】図２
