PROBLEM TO BE SOLVED: To provide an accumulator integrated with an internal heat exchanger, and a refrigeration cycle using the same, capable of improving heat exchanging efficiency between a low-temperature refrigerant and a heat exchange pipe.SOLUTION: As a heat exchange pipe 60 is formed between an outer member 20 and an inner member 30 in a state of being spirally extended in a circumferential direction of the outer member 20 and the inner member 30, and a refrigerant circulation passage 51 in which a low-temperature refrigerant is circulated, is formed between spiral parts 63 of the heat exchange pipe 60, the heat exchange pipe 60 can be formed with a sufficient length, the low-temperature refrigerant can be circulated in the spiral refrigerant circulation passage 51 along the heat exchange pipe 60, and a circulation length of a low-temperature refrigerant in the internal heat exchange chamber 50 can be elongated. Here, as the low-temperature refrigerant in the refrigerant circulation passage 51 and a high-temperature refrigerant in the heat exchange pipe 60 are circulated in directions opposed to each other, flows of the low-temperature refrigerant and the high-temperature refrigerant in the internal heat exchange chamber 50 become countercurrent flows.SELECTED DRAWING: Figure 6
【課題】低温冷媒と熱交換パイプとの熱交換効率を向上させることのできる内部熱交換器一体型アキュムレータ及びこれを用いた冷凍サイクルを提供する。【解決手段】熱交換パイプ60を外側部材20と内側部材30との間に外側部材20及び内側部材30の周方向に螺旋状に延びるように形成するとともに、熱交換パイプ60の螺旋状部分63の間に低温冷媒を流通する冷媒流通路51を形成したので、熱交換パイプ60を十分な長さに形成することができるとともに、低温冷媒を熱交換パイプ60に沿った螺旋状の冷媒流通路51を流通させることができ、内部熱交換室50内における低温冷媒の流通距離を長くすることができる。この場合、冷媒流通路51内の低温冷媒と熱交換パイプ60内の高温冷媒とを互いに反対方向に流通させるようにしたので、内部熱交換室50内における低温冷媒と高温冷媒の流れが対向流となる。【選択図】図6
