    • In a refrigerant cycle device having an ejector, a branch portion for branching a flow of refrigerant flowing out of the ejector into at least a first refrigerant stream and a second refrigerant stream is located. A first evaporator for evaporating the refrigerant of the first refrigerant stream is located to allow the refrigerant to flow to a suction side of the compressor, and a second evaporator for evaporating the refrigerant of the second refrigerant stream is located to allow the refrigerant to flow to an upstream side of a refrigerant suction port of the ejector. In addition, the branch portion is located to maintain a dynamic pressure of the refrigerant flowing out of the ejector, and the second evaporator is connected to the branch portion in a range where the dynamic pressure can be applied to an inside of the second evaporator.

    • An ejector refrigerant cycle device includes a radiator for radiating heat of high-temperature and high-pressure refrigerant discharged from a compressor, a branch portion for branching a flow of refrigerant on a downstream side of the radiator into a first stream and a second stream, an ejector that includes a nozzle portion for decompressing and expending refrigerant of the first stream from the branch portion, a decompression portion for decompressing and expanding refrigerant of the second stream from the branch portion, and an evaporator for evaporating refrigerant on a downstream side of the decompression portion. The evaporator has a refrigerant outlet coupled to the refrigerant suction port of the ejector. Furthermore, a refrigerant radiating portion is provided for radiating heat of refrigerant while the decompression portion decompresses and expands refrigerant. For example, the refrigerant radiating portion is provided in an inner heat exchanger.
    • 喷射器制冷剂循环装置包括用于散发从压缩机排出的高温高压制冷剂的散热器的散热器,将散热器的下游侧的制冷剂流分支为第一流和第二流的分支部, 喷射器,其包括用于从分支部分减压和消耗第一流的制冷剂的喷嘴部分,用于从分支部分减压和膨胀第二流的制冷剂的减压部分和用于在第二流的下游侧蒸发制冷剂的蒸发器 减压部分。 蒸发器具有联接到喷射器的制冷剂吸入口的制冷剂出口。 而且,在减压部减压膨胀制冷剂的同时,设置制冷剂的散热部,用于散热制冷剂的热量。 例如,制冷剂散热部设置在内部热交换器中。
