Abstract
A tank to header attachment construction for heat exchangers include T-shaped tabs on the header which extend through slots in a flange on a tank. The top bar of each tab has it ends bent out of alignment with the slot to secure the tank to the header.
Claims6
A heat exchanger having a plurality of tubes, each of the tubes having an open end, the heat exchanger comprising:
- a tank having a flange that extends around an periphery of an open end of the tank, the flange having a plurality of spaced openings;
- and
- a header supporting the open ends of the tubes and including
- a plurality of tabs extending from an outer periphery of the header, the tabs passing through the openings and bent to a position overlying the flange to prevent removal of the tank from the header.

A heat exchanger having a plurality of tubes, each of the tubes having an open end, the heat exchanger comprising:
- a tank having a flange extending from an outer periphery of the tank, the flange having a plurality of spaced openings;
- a header receiving the open ends of the tubes, the header having a slot, the header further including
- a plurality of T-shaped tabs extending from an outer periphery of the header and passing through the openings in the tank, each of the T-shaped tabs has an upright part extending from the outer periphery of the header and a top bar connected with the upright part, with the T-shaped tab passing through the openings, the top bars are bent to a position overlying the flange of the tank to prevent removal of the tank from the header;
- and
- a deformable tab extending from the outer periphery of the header;
- a side piece including
- a T-shaped tab extending from the side piece, the T-shaped tab having an aperture, the T-shaped tab having an upright part extending from the side piece and a top bar connected with the upright part, with the T-shaped tab of the side piece located in the slot and passing through the corresponding opening in the tank, the deformable tab of the header is deformed into the aperture to lock the side piece to the header and the top bar is bent to a position overlying the flange of the tank to prevent removal of the tank.
