  • Header tubes for heat exchangers and the methods used for their manufacture
    Patent number: 5881456
    Abstract: A header tube for heat exchangers with a tube segment having slots which are perpendicular to the tube axis and spaced in the longitudinal direction and separated by webs, into which hollow flat pipes can be inserted and joined to the contact surface of the respective slot. The webs each have a pair of stampings to strengthen the material on each side of each web and the webs are shaped largely flat such that the cross-section of the tube segment has a largely D-shaped profile. A method of manufacturing the header tubes is also presented.
