  • Patent number: 9827638
    Abstract: Each heat exchange tube of a condenser is formed of a first brazing sheet having a core material and a first brazing material covering the core material. The tank body of each header tank is formed of a second brazing sheet having a core material and a third brazing material covering the core material and being lower in flowability than the first brazing material. In a region of a surface of each protrusion portion facing the corresponding heat exchange tube, the region having a predetermined width as measured from the projecting end, the core materials of the two brazing sheets are brazed together by means of the first brazing material. In the region other than the brazed portion, the core materials of the two brazing sheets are brazed together by means of a fillet formed of a mixture of the first and third brazing materials.

  • Publication number: 20060151155
    Abstract: A heat exchanger (1) which comprises a plurality of flat hollow bodies (2) arranged in parallel, and an aluminum fin (3) disposed between each pair of adjacent flat hollow bodies (2) and brazed thereto. The flat hollow body (2) is made from two plates (6) of an aluminum clad material comprising an aluminum core and a cladding of Al—Si brazing material covering at least one outer surface of the core, by brazing peripheral edges of the two plates to each other. The core of the clad material is made of an alloy containing 0.4 to 1.5 mass % of Cu and the balance Al and inevitable impurities. A line graph representing variations in potential relative to the depth of a surface layer portion of an outer surface of the flat hollow body (2) from the outermost surface thereof to a depth of 100 ?m has a potential gradient of at least 0.25 mV at points on the line of the graph. The heat exchanger can be fabricated easily at a low cost and has satisfactory resistance to pitting corrosion.

  • Patent number: 6608279
    Abstract: A piercing nozzle (2) having a nozzle hole (2a) larger than the diameter of a converged laser beam (10) and smaller than the diameter of a hole (1a) of a cutting nozzle (1) is in use. Further, an underlay (3) having a hole (3a) at a position corresponding to the nozzle hole (2a) is placed under the piercing nozzle (2) through a clearance (5). Piercing is carried out by irradiating the laser beam (10) to a machining target (6) through nozzle holes (1a, 2a) and (3a) on condition that a laser oscillator is set to output high power. The diameter of a hole machined by the piercing is small, and less scattered dross is produced. The scattered dross is cooled down within the clearance (5) and is then dropped down to the underlay (3), so that the adhesion of the scattered dross to the machining target does not occur. Since a small hole is machined with the high power, the machining time for piercing is remarkably shortened.

  • Patent number: 6453990
    Abstract: A layered heat exchanger for use in evaporators or the like has a pipe mount plate which is given improved amenability to brazing at the portion thereof between a fluid introduction pipe socket and a fluid discharge pipe socket provided on the plate. This feature reliably precludes the development of a shortcut channel between the fluid introduction channel and the fluid discharge channel due to a faulty brazed joint.
