Definitions

  • the present invention relates to a tube for an exchanger heat and a method of manufacturing such a tube, and more particularly a tube said to be bent of a type suitable for when brazing in the oven.
  • U.S. Patent No. 1,937,343 discloses a motor vehicle radiator which has bent type tubes.
  • the tubes of this prior art document have a seal in an end part of the section of the tube, this joint being formed by folding, each on itself, the two parts of edge of the very thin metal from which the tube is made, then securing folded parts, flat, against surfaces inside the tube wall.
  • the transverse curvature of the joint gives a good blocking and aids in welding the joint.
  • An object of the present invention is therefore to provide improved structure and manufacturing process improved.
  • said method further comprises the production of flow penetration between said region end of said inner wall and said wall exterior and between said end of said exterior wall and said transition region.
  • said method further comprises a operation consisting in brazing together said walls indoor and outdoor.
  • Said brazing operation advantageously comprises the NOCOLOK soldering (registered trademark).
  • a tube for a heat exchanger having a cross section with two side walls opposite and two opposite ends, said ends opposite including curved parts, the outer surface said ends being substantially symmetrical in mirror, one of said ends having a double wall comprising an inner wall and an outer wall, a said side walls extending to form the wall outer and the other of said side walls extending to form the inner wall, on which each of said outer and inner walls at a respective end, the inner wall being, in a region covered by the end of the outer wall, offset inward to receive said end of the outer wall, and the end of the inner wall deviating from the wall outside.
  • said tube also comprises seals brazed extending between parts of said inner walls and outdoor.
  • said opposite ends comprise each a substantially flat part which makes the section of said oblong tube.
  • a radiator tube 1 is formed at from a single thin sheet of metal so as to have two long, generally flat side parts opposite 2, 3 and two opposite end portions 4, 5.
  • a first end portion 5 of the cross section of the tube is formed by folding set of extensions long side walls so that one of the walls long side panels, wall 2 extends to form a wall interior 7 in the end region 5 and the opposite wall 3 extends to form an outer wall 8 in the region end 5.
  • the inner wall 7 curves around practically from the whole end region 5 before fold in on itself, again on practically the whole end region 5.
  • the outer wall 8, likewise, extends practically around the entire end region 5 before fall back on itself to place itself between the two sections of the inner wall 7, so that there are four metal thicknesses in the end region 5.
  • a radiator tube 10 is shaped generally oblong and has two opposite long walls substantially planes 11, 12 and two end portions 13, 14, these the latter in this case comprising flat parts 15, 16 which are connected by curves with opposite long walls 11, 12.
  • the long walls 11 and 12 form the walls side of the tube also called "sides”.
  • An end region 13 of the tube has a double wall, this comprising an outer wall 16 which is a extension of a first 11 of the long walls and a inner wall 17 which is an extension of the second long, opposite wall 12.
  • the outer wall 16 is generally symmetrical mirroring the wall of the opposite end part 14.
  • the second long wall 12 is connected by a transition region 30 to the inner wall 17, which closely follows the contour inside the outer wall 16.
  • the wall interior 17 continues to an extreme region 31, where it curves inward away from the wall exterior 11, 16.
  • the part 31 deviates from the initial part of the first long wall 11.
  • the transition region 30 abruptly deviates from the line of the second long wall 12 to receive the part end of the outer wall 16 in order to comply with the general envelope of the tube.
  • the outer surface 32 of the transition region 30 is slightly away from the surface interior 33 of the exterior wall 16 in the region immediately adjacent to the end of the outer wall 16 to provide space for the flow passage between the walls.
  • the end region 31 of the interior wall has a outer surface 35 which is spaced from the inner surface of the second long wall 11, again in order to provide a path for flow penetration to ensure the soldering.
  • Figure 4 shows a second embodiment of the invention which has no planar part in the end regions, and we see here that the end 131 of the interior wall 17 deviates from the outer wall 16 in a region where the latter still curves around towards the first long wall 11.
  • the tube can be formed on a bending machine, with the end region 31, 131 formed at the first posts on the edge of the starting reel.
  • the tube thus formed is particularly suitable for NOCOLOK brazing technique for alloy radiators. Other techniques are however possible.
