PROBLEM TO BE SOLVED: To improve the heat exchange performance of a stacked heat exchanger implementing heat exchange between the refrigerant of a refrigeration cycle and a heat medium.SOLUTION: A plurality of refrigerant channels 121 include an upstream refrigerant channel 121A, and a downstream refrigerant channel 121B in which refrigerant lower in dryness than refrigerant flowing in the upstream refrigerant channel 121A flows, a first wall portion 41 in contact with the refrigerant is provided within the upstream refrigerant channel 121A, a second wall portion 42 in contact with the refrigerant is provided within the downstream refrigerant channel 121B, and a second inclination angle is set smaller than a first inclination angle if it is assumed that an angle from 0° to 90°formed between a refrigerant flow direction and a longitudinal direction of the first wall portion 41 is the first inclination angle in a cross-section of the upstream refrigerant channel 121A in a view from a stacking direction of plate members 11, and that an angle from 0° to 90° formed between the refrigerant flow direction and a longitudinal direction of the second wall portion 42 is the second inclination angle in a cross-section of the downstream refrigerant channel 121B in a view from the stacking direction of the plate members 11.

    【課題】冷凍サイクルの冷媒と熱媒体とを熱交換する積層型熱交換器において、熱交換性能を向上させる。【解決手段】複数の冷媒流路121は、上流側冷媒流路121A、および、上流側冷媒流路121Aを流れる冷媒よりも乾き度の低い冷媒が流れる下流側冷媒流路121Bを有しており、上流側冷媒流路121A内には、冷媒と接触する第1壁部41が設けられており、下流側冷媒流路121B内には、冷媒と接触する第2壁部42が設けられており、板状部材11の積層方向から見た上流側冷媒流路121Aの断面において、冷媒の流れ方向と第1壁部41の長手方向とが成す、0?以上、90?以下の角度を、第1傾斜角度とし、板状部材11の積層方向から見た下流側冷媒流路121Bの断面において、冷媒の流れ方向と第2壁部42の長手方向とが成す、0?以上、90?以下の角度を、第2傾斜角度としたとき、第2傾斜角度を第1傾斜角度よりも小さくする。【選択図】図1
