Definitions

  • the invention relates to heat exchangers, in particular for motor vehicles.
  • It relates more particularly to a heat exchanger comprising a multiplicity of stacked plates provided each of a raised peripheral edge, and in which said peripheral edges are tightly assembled to delimit between the plates the first flow channels for a first fluid which alternate with second channels flow for a second fluid.
  • a heat exchanger of this type also called a “heat exchanger with plates “, or” blade exchanger ", is known in particular according to the publication DE-A-195 11 991.
  • Such a heat exchanger heat is used for example as a cooler automotive oil, for cooling engine oil or cooling the oil of the automatic gearbox, by exchange thermal with coolant, usually the one used to cool the vehicle engine.
  • the plates are usually made by stamping a metal sheet, and are stacked so that their peripheral edges respective fit into each other and be then brazed together to seal, which used to define fluid circulation channels.
  • the heat exchanger thus results from a stack of plates and does not require a housing.
  • An inlet manifold and a manifold are then provided. outlet for a first fluid which communicate with a first series of channels, as well as an inlet pipe and an outlet for a second fluid which communicate with a second set of channels, so that the channels of the first series alternate with the channels of the second series.
  • the plates have openings located to the right of the aforementioned tubing and alternatively sealed, or by stampings, either by added rings, to ensure or prohibit the passage of one or the other fluid.
  • the plates have a generally planar bottom and is provided in each flow channel, a disturbing element for favor a turbulent flow of the fluid and therefore the exchange thermal.
  • the object of the invention is in particular to overcome the drawbacks cited above.
  • the invention also aims to provide such a heat exchanger plate heat suitable for good heat exchange between the two fluids, without increasing the loss of load of the circuit of the first fluid and of the circuit of the second fluid.
  • the invention provides for this purpose a heat exchanger of type defined in the introduction, in which the peripheral edge statement of each of the plates is substantially planar and shaped with the direction of assembly or stacking an acute angle a with a chosen value greater than or equal to 10 °.
  • the value of the acute angle ⁇ is less than or equal to 45 °.
  • the first channels and the second channels are free of disturbing elements.
  • the plates are formed by stamping a metal sheet, preferably based on aluminum.
  • the raised edges of the plates are advantageously assembled between them by soldering.
  • the exchanger heat is realized in the form of a cooler motor vehicle oil, in which one of the fluids is engine oil or transmission oil automatic vehicle speeds while the other fluid is a coolant.
  • the heat exchanger shown in Figure 1 includes a multiplicity of plates 10, also called “half-blades”, stacked in a direction of assembly or stacking D, according to an assembly technique called "scales".
  • the plates 10 are here similar to each other and have each a bottom 12 surrounded by a peripheral edge 14 which is generally flat and raised upwards.
  • the bottom 12 a here the general shape of a rectangle with rounded angles, but could have another form for example that of a square with rounded corners.
  • the bottom 12 is here shown plan, but could alternatively present embossed or projecting reliefs, for example ribs or ripples.
  • the plates 10 are formed by stamping a sheet metallic, preferably based on aluminum, which is advantageously coated with solder plating on at least one of its faces.
  • the plates 10 are stacked in the direction D and thus come into mutual contact at their periphery by their respective raised edges 14, which are brazed together to ensure a tight mechanical connection ( Figures 1 and 2).
  • the heat exchanger further includes (Figure 1) a inlet manifold 16 and outlet manifold 18 for a first fluid F1, as well as an inlet pipe 20 and a outlet pipe 22 for a second fluid F2.
  • the plates 10 thus delimit between them channels 24 for the first fluid F1 which alternate with channels 26 for the second fluid F2 ( Figure 2).
  • each of the plates 10 form with the direction of assembly or stacking D at an angle acute ⁇ with a chosen value greater than or equal to 10 ° (figure 2). Furthermore, this chosen value is preferably lower. or equal to 45 °.
  • Tubes 16, 18, 20 and 22 extend inside of the stack and means are provided for making communicate the pipes 16 and 18 with the first channels 24, on the one hand, and the pipes 20 and 22 with the second channels 26, on the other hand. These means of communication, in themselves known, are not described. Details on this can be found in particular in publication DE-A-195 11 991 cited above.
  • channels 24 and 26 are generally devoid of disturbing elements suitable for modifying the flow regime of fluids in the heat exchanger, as can be seen in the figure 2.
  • disturbing elements 28 are provided only in the channels 26 traversed by the fluid F2, while the channels 24 traversed by the fluid F1 lack them.
  • the disturbing elements 28 can be formed for example by reliefs from plates 10.
  • the heat exchanger advantageously constitutes a cooler oil. It can be used to cool the oil of the engine or the oil of the automatic gearbox of a motor vehicle. In this case, one of the fluids is made up of this oil, while the other fluid is consisting of a cooling fluid. This last one is advantageously the liquid which is usually used for motor vehicle engine cooling.
  • the heat exchanger When the heat exchanger is used to cool engine oil, it is then fixed either directly on the engine block, either on a connected filtration unit directly to the engine.
  • the exchanger can then be connected to the coolant circuit through conduits.
  • the heat exchanger can be connected directly to the oil pan of the gearbox speeds.
