Abstract
A heat exchanger includes at least one elongate header of metal, a plurality of refrigerant flow tubes each having one open end exposed to the interior of the header and a plurality of heat radiation fins extending along the tubes. A connector of metal is brazed to the header to provide a fluid communication between the interior of the header and an external pipe member through an opening formed in a wall of the header. The connector comprises a mating surface which mates the wall of the header; a connecting surface positioned at an opposite side of the mating surface; a pair of side surfaces each being positioned between the mating and connecting surfaces; a through bore which extends between the mating and connecting surfaces; and a groove formed in each of the side surfaces along an axis of the elongate header. The groove is positioned close to the mating surface to leave or define therebetween a thin mounting portion of the connector. The thin mounting portion is so sized as to achieve a desired argon arc spot welding between the connector and the wall of the header.
