Claim Text:
1. An evaporator with a cool storage function, the evaporator comprising: a plurality of flat refrigerant flow tubes having a longitudinal direction and a width direction which is perpendicular to the longitudinal direction, the plurality of flat refrigerant flow tubes is configured such that air is to pass in a direction parallel to the width direction, the plurality of flat refrigerant flow tubes being disposed in parallel and spaced apart from one another in a thickness direction of the plurality of refrigerant flow tubes to form spaces among the plurality of flat refrigerant flow tubes, the thickness direction being perpendicular to the longitudinal direction and the width direction; outer fins disposed in a first part of the spaces and joined to the plurality of refrigerant flow tubes; and at least one cool storage material container containing a cool storage material and disposed in a second part of the spaces other than the first part, the at least one cool storage material container comprising: a container main body having a first wall and a second wall opposite to the first wall which are substantially parallel to a plane including the longitudinal direction and the width direction, the first wall and the second wall being connected to adjacent refrigerant flow tubes among the plurality of refrigerant flow tubes, respectively; condensed water drain passages provided on outer surfaces of the first wall and the second wall; and a plurality of convex portions provided on the first wall and the second wall to protrude outwardly from the first wall and the second wall, two adjacent convex portions among the plurality of convex portions forming each of the condensed water drain passages therebetween, the condensed water drain passage extending in an extending direction from a first end of the condensed water drain passage to a second end of the condensed water drain passage obliquely with respect to the longitudinal direction, at least one of the two adjacent convex portions having a length in the extending direction greater than a width of the container main body in the width direction, wherein the condensed water drain passages and the convex portions of the first wall are shifted in the width direction from the condensed water drain passages and the convex portions of the second side wall such that the condensed water drain passages and the convex portions of the first wall of the container main body do not entirely overlap with the condensed water drain passages and the convex portions of the second wall when viewed in a direction parallel to the thickness direction.
