Abstract A tube and header construction which may be used in a cooling radiator for an internal combustion engine in which one end of each tube extends into the header through an opening in a wall member forming a liquid-confining part of the header and with spaced end portions of the tube end within the header being separate from the remainder of the tube and distorted to extend away from this remainder thereby to secure the tube end to the header wall member. In one embodiment of the invention these spaced end portions of the tube within the header are curved over until their extreme ends are in contact with the inner surfaces of the wall member. In another embodiment the tube end portions are used to secure a solid joining material such as a brazing material in position to be activated as by melting in a subsequent joining operation where it is in position to bond the tube to the header.
A tube and header construction, comprising: a wall member forming a liquid confining part of said header having an opening; a tube end extending into said header through said opening; and means forming spaced end portions of said tube end within the header extending away from the remainder of said tube end within said header and thereby securing said tube end to said header wall member.
