PROBLEM TO BE SOLVED: To obtain a small heat exchanger which achieves excellent reliability by providing a heat insulation part that inhibits freezing of a fluid.SOLUTION: A heat exchanger includes: a first refrigerant passage 1 where a first fluid flows along a first axis X direction; a second refrigerant passage 2 where a second fluid, which conducts heat exchange with the first fluid, flows along the first refrigeration passage 1; a first inlet header 3 and a first outlet header 4 which are connected with both ends of the first refrigerant passage 1; a second inlet header 5 and a second outlet header 6 which are connected with both ends of the second refrigerant passage 2; and a heat insulation part 21 which inhibits heat exchange between the first fluid and the second fluid and is located between the first refrigerant passage 1 and the second refrigerant passage 2 at end parts of the first refrigerant passage 1 and the second refrigerant passage 2. 【課題】流体の凍結を抑制する断熱部を設けることによって、信頼性が優れる小型の熱交換器を得ることを目的にしている。【解決手段】第１流体が第１軸Ｘ方向に沿って流れる第１冷媒流路１と、前記第１流体と熱交換を行う第２流体が、前記第１冷媒流路１に沿って流れる第２冷媒流路２と、前記第１冷媒流路１の両端に接続された第１入口ヘッダー３および第１出口ヘッダー４と、前記第２冷媒流路２の両端に接続された第２入口ヘッダー５および第２出口ヘッダー６と、前記第１冷媒流路１と前記第２冷媒流路２との端部において、それらの流路の間に、前記第１流体と前記第２流体との熱交換を抑制する断熱部２１と、を有する熱交換器。【選択図】図１
