Abstract
Abstract There is illustrated and described herein a heat exchanger including rows of tubes, a pair of headers secured to the ends of the tubes, a groove formed in each of the headers adjacent the peripheral wall thereof and intermediate adjacent rows of tubes, a recessed portion formed along the full length of the centerline of each groove, a pair of tanks having walls aligned with and mounted in the grooves of the respective headers, a ledge formed around the outside wall of each header, a chamfer formed along each of the inner and outer edges of the tank walls to form a blunt edge at the ends of the chamfers, and a gasket mounted in each groove and depressed along its centerline into said recessed portions by the blunt edge, the tanks being retained in position by bending spaced extensions of the peripheral wall of each header onto the ledge.
