ADVANCED BRAZE JOINT FOR TUBE-TO-TUBE CONNECTION

摘要

Systems for tube-to-tube connections (301) are described herein. A device (300) having an aperture (307) for receiving a tube (340) may comprise: an inlet portion (316) comprising a first diameter (326), the inlet portion (316) located at an inlet (306) of the aperture (307); a braze filler collector portion (314) located axially adjacent to the inlet portion (316) comprising a second diameter (324), the second diameter (324) being greater than the first diameter (326); a necked portion (312) located axially adjacent to the braze filler collector portion (314) comprising a third diameter (322), the third diameter (322) being less than the first diameter (326) and the second diameter (324); a flow surface (310) comprising a fourth diameter (320), the fourth diameter (320) being less than the third diameter (322), the flow surface (310) defining a void; and a collection pocket (318) located axially adjacent to the necked portion (312), the collection pocket (318) configured to collect a braze filler material (348) from the necked portion (312) to prevent the braze filler material (348) from contacting the flow surface (310).
