(54) Heat exchanger constructed by plural heat conductive plates


(57) A pair of heat conductive plates (12) forming an evaporator core portion (11) has a plurality of projection ribs (14). The projection ribs (14) protrude toward outsides of the pair of heat conductive plates (12) for forming refrigerant passages thereinside. Air flows outside the heat conductive plate perpendicularly to a flow direction of the refrigerant, and is prevented from flowing straightly by the projection ribs (14)to make a turbulent flow.
