Definitions

  • the invention relates to heat exchangers of the tubular type, that is to say comprising a bundle formed of a multiplicity of tubes intended to be traversed by a fluid.
  • Heat exchangers of this type are used in particular in motor vehicles to provide either cooling of the engine, or heating of the passenger compartment, or even conditioning of the air in the passenger compartment.
  • the invention relates to a heat exchanger tube comprising an integrated disturbing device capable of generating turbulence when a fluid flows through this tube.
  • a known solution for this consists in introducing into the tube, after its manufacture, an additional part called a “disruptor” or “turbulator” and possibly then fixing this part inside the tube, for example by brazing.
  • This solution is not satisfactory because it requires a particular operation for mounting a disturbing device inside each tube.
  • EP-A-0 302 232 is a heat exchanger tube comprising a metal strip rolled and welded on itself which has a part extending inside the tube to form a device disruptor capable of generating turbulence on a fluid circulating in the tube.
  • the disturbing device is formed by a part of the strip itself, which avoids the need for an additional part as in the case of the solution mentioned above.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • a heat exchanger tube of the type defined above in which the strip has two marginal parts extending on either side of a central part, at least one of the marginal parts forming disturbing device and each of the marginal parts being folded, along a folding edge, towards the central part, and in which the two folding edges are brought towards each other by winding the central part and the parts edges of the strip and welded to each other.
  • a tube with an integrated disturbing device is thus obtained which can be produced with simple tools and which does not require complicated manufacturing operations as in the case of the prior art.
  • the tube is obtained by rolling and welding on itself a metal strip of particular structure comprising a disturbing device provided on at least one of the two marginal parts of the strip which extend on either side another of a central part which does not form a disturbance.
  • the two marginal parts of the strip each form a disturbing device.
  • the central part of the strip has a smooth wall and extends over a width greater than the upper perimeter of the rolled tube, while each of the lateral parts of the strip extends over a smaller width at the outer half-perimeter of the rolled tube.
  • the strip has, flat, a width substantially equal to twice the external perimeter of the tube in the rolled state.
  • the marginal parts of the strip are delimited externally by two end edges which extend parallel to each other and which constitute the edges of the strip flat, the two end edges being close to each other. 'from each other in the tube in the rolled state.
  • each of the two folding edges of the strip is formed by winding the strip on itself. This makes it possible to obtain more resistant folding edges and offering better welding possibilities.
  • the disturbing device formed in one or each of the marginal parts of the strip is obtained by deformation of the wall thereof.
  • Each of the marginal parts may include, for example, perforations, punctures or even spikes.
  • the strip intended to form the tube of the invention is plated with solder. Under these conditions, the two marginal parts are joined by brazing with the central part, thus forming an extremely rigid double-walled tube, capable of withstanding the pressure of the fluid passing through this tube.
  • FIG. 1 shows a strip 10, in its initial flat configuration, intended for the manufacture of a rolled tube for heat exchanger according to the invention.
  • the strip 10 extends over a width L delimited by two end edges 12 which extend parallel to each other.
  • the strip 10 is further delimited by two opposite faces 14 and 16 which extend over the entire width of the strip and which define the thickness of the latter.
  • the strip 10 is made of a metallic material of the type used for the manufacture of heat exchanger tubes, for example aluminum or an aluminum alloy.
  • the strip is advantageously coated with a solder plating (not shown in FIG. 1) on its two opposite faces 14 and 16.
  • the strip 10 has two marginal parts 18 each forming a disturbing device and extending on either side of a central part 20.
  • the width L of the strip 10 corresponds substantially to twice the external perimeter P of rolled tube to be manufactured.
  • Each of the marginal parts 18 extends over a width II less than the external half-perimeter P / 2 of the rolled tube to be manufactured.
  • the central portion 20 extends over a width 1 2 greater than the outer perimeter P of the tube. It thus follows that the width 1 2 of the central part is greater than the sum of the respective widths of the two marginal parts 18, that is to say greater than twice 1 1 .
  • the central part 20 of the strip has a smooth wall, that is to say that the faces 14 and 16 are smooth in the central region of the strip.
  • the wall of the strip is deformed in each of its marginal parts 18, in order to produce a disturbing device.
  • the disturbing device of each of the marginal parts 18 is formed of a multiplicity of holes 22 which pass through the thickness of the strip right through between its opposite faces 14 and 16.
  • the holes 22 are evenly spaced and are provided over the entire Width 1 1 of each of the marginal portions 18 and over the entire length (not shown) of the strip.
  • the holes 18 may have a circular configuration or any other configuration of suitable shape.
  • each of the marginal portions 18 is folded along a folding edge 26, towards the central part 20 and attached to the latter.
  • each of the marginal parts 18 is attached to one half of the central part 20, the end edges 12 of the strip coming close to one another.
  • the folded edges 26 are rolled edges, and not straight folded edges, to allow reinforcement and a better possibility of welding as will be seen below.
  • the rolled edges 26 thus each define an internal space 28 which extends above all the length of the folded strip.
  • the internal space 28 can be reduced during the folding operation.
  • edges 12 can come into abutment against one another, or even overlap.
  • the strip is rolled so as to bring the rolled edges 26 together until they come into contact with one another.
  • This rolling operation makes it possible to form a rolled tube of determined section, for example of general oval shape. The rolling is carried out so that the marginal parts 18 are inside the tube.
  • the rolled edges 26 When the rolled edges 26 are in contact with one another, they are joined together by a welding operation. In the case where the strip is coated with a solder plating, the rolled tube is placed in a suitable oven to cause the solder plating to melt. This not only gives the welding of the edges 26 to each other but also the welding of the marginal parts 18 attached to the central part 10.
  • each of the marginal parts 18 comprises punctures 30 obtained by stamping the wall of the strip, which makes it possible to form reliefs projecting relative to the face 14.
  • the strip is wound in the same way as in the case of FIG. 2 to form a rolled tube 32 also having an oval section.
  • each of the parts 18 comprises a multiplicity of pins 34 protruding from the face 14.
  • the pins 34 are obtained by deformation of the strip wall using a multiplicity of punches, in the form of knobs, applied against the face 16 of the strip.
  • a rolled tube 36 is formed of flattened cross section having substantially a rectangular shape.
  • the marginal parts 18 are inside the tube and each form a disturbing device thanks to the reliefs provided by the wall.
  • the invention is not limited to the embodiments described above by way of example and extends to other variants.
  • other types of disturbing devices as a function of the deformations imposed on the marginal parts of the strip, in particular deformations consisting of ridges deploying in a manner substantially parallel to the axis or according to one or more coaxial turns to said axis. .
  • the invention finds a particular application in the manufacture of heat exchangers for a motor vehicle.
