Abstract
A method of making a heat exchanger that includes sealing tubes to header slots and brazing the tubes to the header slots. The method further includes coupling a cover to the header to cover a liquid-side surface of the header and to cover ends of the tubes, and applying flux to an air-side surface of the header and to the tubes. Coupling the cover to the header is performed after sealing the tubes to the header slots and coupling the cover to the header is performed before applying flux to the air-side surface of the header and to the tubes. Applying flux is performed before brazing each of the tubes to the header slots and sealing each of the tubes to the header slot includes sealing a perimeter of each of the tubes to the header slot.
Claims20
A method of making a heat exchanger, the method comprising:
- arranging a plurality of tubes in a formation;
- coupling the plurality of tubes to a header, including sealing each of the tubes of the plurality of tubes to a header slot of a plurality of header slots in the header and brazing each of the tubes of the plurality of tubes to said header slot of the plurality of header slots;
- coupling a cover to the header to cover a liquid-side surface of the header and to cover ends of the tubes;
- and
- applying flux to an air-side surface of the header and to the plurality of tubes,
- wherein coupling the cover to the header is performed after sealing each of the tubes of the plurality of tubes to said header slot of the plurality of header slots,
- wherein coupling the cover to the header is performed before applying flux to the air-side surface of the header and to the plurality of tubes,
- wherein applying flux is performed before brazing each of the tubes of the plurality of tubes to said header slot of the plurality of header slots, and
- wherein sealing each of the tubes of the plurality of tubes to said header slot includes sealing a perimeter of each of the tubes to said header slot.
