Method of making a heat exchanger

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...

Zusammenfassung: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.
