Definitions

  • the present invention relates to a heat exchanger, for example a heat exchanger for a motor vehicle. More specifically, the invention relates to a heat exchanger for the exchange between a first fluid and a second fluid, wherein the first fluid is for example a gaseous fluid such as air and the second liquid fluid such as 'water.
  • the heat exchanger according to the present invention is particularly suitable for use in cooling the charge air.
  • boost air compressed air
  • Compressed air is obtained using a compressor driven by the exhaust gas. Therefore, the compression of the air has the effect of heating the air.
  • it is necessary to cool the compressed air before its introduction into the engine, to lower the temperature of the air before its introduction into a cylinder of the engine.
  • a heat exchanger comprising a heat exchange bundle consisting of an assembly of plates, positioned one on the other and forming in combination a conduit for guiding a fluid. such as a liquid, from an inlet to an outlet.
  • a fluid such as a liquid
  • the heat exchange bundle is positioned within a housing or housing.
  • This housing is provided with an inlet and an outlet for the second fluid to be cooled, such as air, and is adapted to guide air from an inlet to an outlet.
  • the housing has the function of a collector box enveloping said heat beam and allowing admission and regulation of the charge air.
  • a housing is for example molded in a material such as aluminum or plastic.
  • the walls of the housings are relatively thin and relatively flexible.
  • the volume of said housings can increase as a function of the increase in pressure and temperature inside the housings.
  • the housing of a heat exchanger is provided with an opening for introducing the heat exchange bundle inside the housing.
  • the heat exchange bundle is, in principle, connected to a closure element such as a hood.
  • the cover allows to connect the assembly of the corrugated plates and corrugated elements of the heat exchanger and to fix the assembly against said connection plate.
  • the hood is provided with conduits allowing the introduction and the emission of the liquid fluid, such as a liquid, inside the heat exchanger.
  • the cap attached to the exchange beam performs a function of closing the opening for the introduction of the heat exchanger.
  • the hood In its position of use, the hood, to which the heat exchange bundle is attached, is in principle positioned substantially horizontally, above said heat exchange bundle. In other words, the heat exchange bundle is suspended from the hood.
  • Heat exchangers known from the prior art have several disadvantages. At first, the connection between the housing and the hood is very fragile and must withstand the high pressure and high temperatures present inside the heat exchanger. In addition, the walls of the housing may, during normal use of the heat exchanger, deform under the pressure of the hot air present inside said heat exchanger. This deformation, constant during use of the heat exchanger, can cause premature wear of the material used in the manufacture of the housing. Thus, the reliability of the housing can be altered.
  • the heat exchange bundle Since the heat exchange bundle is suspended from the hood, the heat exchange bundle can exhibit pendular movements under the influence of the vibrations imposed by the operation of the engine of the vehicle with which the heat exchanger is used. The repetition of these pendular movements, especially in the presence of a resonance effect, can have a detrimental influence on the reliability of the heat exchanger.
  • the heat exchanger according to the present invention aims to overcome the disadvantages of heat exchangers, as disclosed in the state of the art, by proposing a new design for the attachment of a heat exchange beam to the heat exchanger. inside the housing of a heat exchanger.
  • the present invention relates to a heat exchanger comprising a housing adapted to envelop a heat exchange bundle, said housing being provided with an opening for receiving said heat exchange bundle within said housing and a heat exchange bundle, said heat exchange bundle including a first end adapted to close the opening of the housing when the heat exchange bundle is inserted inside said housing, characterized in that a second end of the heat exchange bundle opposite said first end is provided with at least one fastening means which is the shape of a peg, for fixing said second end of the heat exchange bundle to the wall of the housing.
  • the figure 1 shows a perspective view of an embodiment of a heat exchanger 1 according to the present invention. Part of the outside of the heat exchanger 1 has been removed to show the inside of said heat exchanger.
  • the heat exchanger as shown on the figure 1 is particularly suitable for use in the automotive industry to cool the charge air (RAS) of a heat engine.
  • the heat exchanger 1 makes it possible to cool the charge air by heat exchange with a first fluid, such as outside air, or a liquid such as, for example, the cooling water of an engine, thus forming an exchanger air / air or liquid / air type.
  • the heat exchanger 1 comprises an intake manifold 2, often designated by the skilled person under the name "intake manifold".
  • the intake manifold 2 is fixed to the cylinder head of the combustion chamber of the engine, that is to say at the inlet of the cylinder. Depending on the engine speed, the air can be cooled, totally, partially or the air can not be cooled.
  • the intake manifold 2 is connected to a housing or housing 3. This housing 3 forms an envelope for a heat exchange bundle 4 located inside said housing 3.
  • the heat exchange bundle 4 is positioned inside a housing 3.
  • This housing 3 is provided with an inlet and an outlet for a first gaseous fluid and is adapted to guide said first fluid from an inlet to an outlet.
  • the heat exchanger 1 comprises a heat exchange bundle 4 consisting of an assembly of plates, positioned one on the other and forming in combination a conduit for guiding a second liquid fluid, used to cool the first gaseous fluid, from an inlet to an outlet.
  • the plate assembly is completed by means of corrugated spacer elements.
  • a first fluid such as air passes outside the heat exchange bundle 4 and a second fluid, such as, for example, water cooling circuit circulates inside heat exchange bundle 4 and thus allows the air to be cooled.
  • the heat exchange bundle 4 is formed of an assembly of stamped plates, also called “half-blades". However, the invention also applies to other types of beams, including beams having tubes and fins.
  • the heat exchange bundle 4, as shown on the figure 2 is formed of a stack of stamped plates arranged in pairs, made identically. Only the two end plates forming the upper end and the lower end of the heat exchange bundle 4, as shown in FIG. figure 1 , are of different shape compared to the stamped plates stacked.
  • Each stamped plate has a rectangular shape and has a substantially planar bottom wall bounded by a rectangular-shaped peripheral rim, which is raised relative to the bottom wall to form a shallow bowl.
  • Each pair of stamped plates delimits a chamber. The use of a plate of this type is known to those skilled in the art.
  • the stamped plates form the heat exchange bundle 4, arranged in pairs.
  • the respective boss of a pressed plate belonging to a pair is in communication with the respective boss of an adjacent stamped plate belonging to a portion of the neighboring stamped plates.
  • the heat exchange bundle 4 comprises corrugated spacer elements 5, as shown in FIG. figure 2 , disposed between pairs of adjacent stamped plates.
  • the various stamped plates and corrugated intermediate elements 5 are, according to a known technique, assembled through a brazing process. After assembly, the heat exchange bundle 4 defines first channels for the gas to be cooled, in which the corrugated spacer elements 5 are present, and second channels for the circulation of the cooling liquid obtained using plates.
  • the set of constituents of the heat exchange bundle 4, the stamped plates, the corrugated spacer elements 5, the inlet manifolds and turbulators for entering and leaving the cooling liquid are advantageously made of an aluminum alloy , assembled together and brazed in a single operation in a brazing furnace.
  • the upper part of the heat exchange bundle 4 is fixed on a closure element 6 such as a plate or a cover 6.
  • the cover 6 performs several functions. One of the functions is to allow the hood inlet and outlet of the coolant by means of pipes disposed on the cover 6. Moreover, the cover 6 forms the closing element of the housing 3.
  • the heat exchange bundle 4 is wrapped, on the one hand by walls formed by the housing 3, and on the other hand by the cover 6.
  • the heat exchanger 1 is provided with fastening elements 21, 22 and 23 which are attached to the lower end of the heat exchange bundle 4.
  • the fastening elements 21, 22 and 23 are adapted to cross the wall of the housing 3 and be fixed to said wall of the housing 3, by means of any suitable means.
  • the figure 2 shows in detail a first embodiment of the fastener 21.
  • figure 2 shows that the walls 31 of the housing 3 comprise a break allowing the fixing element 21 to pass through.
  • the fastening element 21 is fastened to the lower end of a heat exchange bundle by means of a soldering process . This means that during the assembly of the heat exchange bundle 4, a single operation, carried out in a brazing furnace, makes it possible to assemble a heat exchange bundle 4 and to fix the fastening elements 21, 22 and 23 at the lower end of the heat exchange bundle.
  • the fixing element 21 may, for example, be fixed on the walls 31 of the housing 3 by means of a nut (not shown).
  • the figure 3 shows a second embodiment of the fixing of a fastening element 41.
  • the fastening element 41 is attached to the lower end of the heat exchange bundle 4 through an elastic assembly means or according to the English name "snap-fit".
  • the figure 4 schematically shows a third embodiment of the fixing of a fastening element 51 on the lower end of a heat exchange bundle 4.
  • the fastening element 51 is made of plastic material which can be deform under the influence of a heat source.
  • a quantity of heat, combined with a quantity of pressure can be used to deform the fixing element 51 and thus fix the lower part of the heat exchanger beam 4 on the wall 31 of the housing 3.
  • the first "female" element can be fixed or assembled, for example by means of a brazing process, on the lower end of the heat exchanger bundle 4. After assembly, this fastening element 61 can be fixed on the wall 31 of the housing 3 by means of a screw 62 forming the "male" element of the fastener 25.
  • the heat exchanger 1 When using the heat exchanger 1 according to the present invention, it is important that the envelope located around the heat exchange bundle 4 is sealed. Thus, the fasteners of the lower part of the heat exchange bundle 4, on the wall 31 of the housing 3, must be made carefully. In order to seal the passage of the fastening elements 21, 22, 23, 41, 51 and 61, it is necessary to provide sealing elements, such as sealing rings.
  • fastening elements 21, 22, 23, 61 can be attached to the lower end of the heat exchange bundle 4 by means of a soldering process . Any other method of attaching fasteners may be envisioned, for example, through the use of a suitable adhesive means.
  • the figure 5 shows the attachment of the heat exchange bundle to the walls of the heat exchanger housing by using a fastener made of plastic, after the application of a certain amount of heat to modify the shape of said element of fixation.
  • the figure 6 represents the attachment of the heat exchange bundle to the walls of the heat exchanger housing using a fastener having "male” and “female” fasteners.
