    摘要： A stacking-type header according to the present invention includes a first plate having a first through-hole; a second plate having a plurality of second through-holes; a third plate in which a flow path that communicates between the first through-hole and the second through-holes is formed, the third plate being disposed between the first plate and the second plate; a first pipe including a first end portion that is inserted into the first through-hole; a plurality of second pipes each including a second end portion that is inserted into a corresponding one of the second through-holes; and brazing portions provided between the first plate and the third plate, between the second plate and the third plate, between the first through-hole and the first pipe, and between the second through-holes and the second pipes. The first pipe includes a first expanded portion in the first end portion, the first expanded portion having an outer peripheral surface that is pressed against an inner peripheral surface of the first through-hole. Each of the second pipes includes a second expanded portion in the second end portion, the second expanded portion having an outer peripheral surface that is pressed against an inner peripheral surface of a corresponding one of the second through-holes.

    摘要： A method of brazing two metal components (8, 9) comprises the following operating steps : prearranging a first metal component (8) provided with a connection end (8') and a second metal component (9) provided with a connection portion (9'), with at least the first component (8) of tubular shape, arranging the first component (8) of tubular shape with its connection end (8') facing the connection portion (9') of the second component (9), defining with the latter a junction slit (21), prearranging a bead (11) of filler material on the mouth of the junction slit (21), irradiating at least one fraction of the connection end (8') of the first component (8) and/or at least one fraction of the connection portion (9') of the second component (9) with at least one laser beam (12), defining thereon an impact area (13) that is outside with respect to the bead (11), in a manner such that the laser beam (12) does not directly hit the bead (11) itself, transmitting, via conduction, thermal energy from the impact area (13) to the bead (11), and melting the filler material, in which the thermal energy, transmitted via conduction to the bead (11), at least partially melts the filler material which consequently penetrates via capillarity into the junction slit (21).
