Each of the header tanksincludes two header sections. Each header tankincludes a first memberto which the heat exchange tubesare connected, and a second memberwhich is joined to the first memberand covers the side of the first memberopposite the heat exchange tubes. Partition portionsfor dividing the interiors of the header sectioninto upper and lower spacesare provided on the second memberof the header tank. Through holesA,for establishing communication between the upper and lower spacesof the header sectionare formed in the partition portions. The second memberis formed by bending a metal plate. This evaporatorrequires a reduced number of components and facilitates production work.
