PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving heat exchange performance by controlling flow of a heat medium.SOLUTION: A plate type heat exchanger configured by stacking a plurality of flow channel formation members and disposing inner fins respectively between the flow channel formation members, has a structure provided with both end portions between the flow channel formation members on a vertical cross-section to an inflow direction of a heat medium, and a wall surface for forcibly shutting off the flow of the heat medium to a clearance of both end portions of the inner fin or for increasing flow channel resistance. As the flow of the heat medium flowing in the clearance of both end portions can be suppressed, heat exchange performance can be improved. |
