PROBLEM TO BE SOLVED: To provide a cooling device which can increase a cooling ability of a refrigeration cycle of an ejector cycle which is driven by exhaust heat of a prime mover such as an engine.SOLUTION: A cooling device 10 of the invention includes: a refrigeration cycle 11 which cools ventilation air or a cooling object fluid; and an ejector cycle 12. The refrigeration cycle 11 has: a compressor 20; a condenser 21; an expansion valve 22; and an evaporator 23. The ejector cycle 12 has: a boiler 31; a condenser 34; an expansion valve 35; an evaporator 33; an ejector 32 which suctions a second refrigerant from the evaporator 33 by a suction force generated by the second refrigerant being guided from the boiler 31; and a pump 30 which transports the second refrigerant to the boiler 31. Further, a first refrigerant discharged from the condenser 21 of the refrigeration cycle 11 is cooled by the evaporator 33 of the ejector cycle 12.SELECTED DRAWING: Figure 2

    【課題】エンジン等の原動機の排熱で駆動するエジェクタサイクルで冷凍サイクルの冷却能力を増大することが出来る冷却装置を提供する。【解決手段】本発明の冷却装置10は、送風する空気または冷却対象流体を冷却する冷凍サイクル11と、エジェクタサイクル12と、を具備する。冷凍サイクル11は、圧縮機20と、凝縮器21と、膨張弁22と、蒸発器23と、を有する。また、エジェクタサイクル12は、ボイラ31と、凝縮器34と、膨張弁35と、蒸発器33と、第2冷媒をボイラ31から導くことで発生する吸引力で蒸発器33から第2冷媒を吸引するエジェクタ32と、ボイラ31に第2冷媒を輸送するポンプ30と、を有している。更に、冷凍サイクル11の凝縮器21から吐出された第1冷媒を、エジェクタサイクル12の蒸発器33で冷却している。【選択図】図2
