PROBLEM TO BE SOLVED: To suppress temperature distribution of distributed air passing through a refrigerant evaporator when a flow rate of a refrigerant flowing in a refrigeration cycle is low.SOLUTION: A refrigerant evaporator 1 is configured by connecting a first refrigerant collecting portion 23a formed inside of a second leeward-side tank portion 23 and a second refrigerant distributing portion 13b formed inside of a second windward-side tank portion 13, and connecting a second refrigerant collecting portion 23b formed inside of the second leeward-side tank portion 23 and a first refrigerant distributing portion 13a formed inside of the second windward-side tank portion 13 to replace the refrigerant flowing direction in the core width direction of heat exchange core portions 11 and 21. A damming plate 24 for damming the flow of a liquid-phase refrigerant flowing therein from a refrigerant inlet portion 22a, is disposed in the first leeward-side tank portion 22. The damming plate 24 is disposed at a position to be superposed to a boundary 110 between a first windward-side heat exchange core portion 11a and a second windward-side heat exchange core portion 11b, when observed from the flowing direction of the distributed air. |
