Abstract

An evaporator with a cool storage function includes flat refrigerant flow tubes and flat cool storage material containers each brazed to one side surface of the corresponding refrigerant flow tube. A plurality of sets each composed of refrigerant flow tubes and a cool storage material container are disposed such that they are spaced from one another. A fin is disposed in an air-passing clearance between adjacent sets, and is joined to the corresponding refrigerant flow tubes and the corresponding cool storage material container. Front portions of the cool storage material containers and the fins project frontward from the refrigerant flow tubes, and an internal-volume-increasing portion, whose container height is greater than that of the container body portion, is provided at the frontward projecting portion of each cool storage material container. Fins are brazed to opposite side surfaces of the internal-volume-increasing portion of each cool storage material container.
