  • Sealing method and apparatus for a heat exchanger
    Patent number: 6082446
    Abstract: A heat exchanger for a vehicle. The heat exchanger includes a tank which has a peripheral foot that is in contact with a seal within a channel of a header. The header is coupled to the tank by a plurality of bendable tabs on the header that are bent onto an upper surface of the peripheral foot. A compression stop located on the external surface of the tank prevents distortion and excessive compression of the seal during the bending operation.
