Definitions

  • the invention relates to the field of heat exchangers, for example for an air conditioning circuit of a motor vehicle.
  • a heat exchanger comprising a body in which are formed a series of first fluid circulation channels and a series of second interchanged fluid circulation channels.
  • Such a heat exchanger is known for example from the document JP 2003-121086 which describes the use of an extruded profile as a body in which first and second fluid circulation channels are provided. It is necessary to connect the first and second fluid circulation channels to separate manifolds or manifolds. To do this, JP 2003-121086 provides that the section transversely traverses a first and a second collector, both cylindrical. A first cut of the profile wall at the first cylindrical collector contacts the inside of the cylindrical collector and the first fluid circulation channels. A second cut made at the second cylindrical collector communicates the interior of the second cylindrical collector and the second fluid circulation channels.
  • Such an exchanger is also known from the document JP 2004 150673 A .
  • the document JP 2003-279 27.6 discloses a heat exchanger whose body is in the form of a single piece in which are formed a series of channels of circulation of fluid aligned. At the ends of the one-piece piece are then produced series of cuts for making series of teeth which are traversed by the fluid circulation channels. For each end of the one-piece piece, the teeth of the series of teeth are alternately folded on one side and the other of a plane containing the bulk of the one-piece piece, defining a series of first teeth and a series of second teeth. The teeth are then received in separate cylindrical or collecting manifolds, which can be connected to the rest of the air conditioning circuit.
  • Such a heat exchanger is difficult to achieve, in particular because of the operation of cutting and bending teeth.
  • the object of the invention is in particular to overcome the aforementioned drawbacks by proposing a heat exchanger of the type mentioned above, in which the body comprises a first crenellated profile body element comprising at least a first groove and at least a first groove. rib, each first rib housing at least one of the first fluid flow channels, and a second crenellated body member having at least one second rib and at least one second groove, each second rib housing at least one second fluid flow channels, the first and second body members interlocking so that each first rib and each second rib are received respectively in a second groove and a first groove.
  • the profile of the first body member includes a plurality of first grooves alternating with a plurality of first ribs and the profile of the second body member includes a plurality of second ribs alternating with a plurality of second grooves.
  • each first rib houses one of the first fluid circulation channels
  • each second rib houses one of the second fluid circulation channels, so that the first and second channels are interposed. This configuration provides good heat exchange performance.
  • each first groove and each second rib are of conjugate shapes so that each first groove completely houses a second rib
  • each second groove and each first rib are of conjugate shapes so that each second groove completely houses a first rib.
  • this configuration improves the heat exchange between the fluid flowing through the channels housed in the first rib or ribs and the fluid flowing through the channels housed in the second rib or ribs.
  • This form cooperation also improves the pressure resistance of the assembled body members, since each rib of one body member contributes to supporting the force resulting from the deformation of the adjacent rib of the other body member. Similarly, the pressures exerted by the fluids traversing two adjacent ribs of different body elements, tend to compensate for themselves through this form cooperation.
  • the first body member comprises a first junction face and the second body member comprises a second junction face, each first and second rib respectively projecting from the first and second faces of the junction face. junction so that each first and second rib jointly defines the first and second junction faces respectively a first and a second groove.
  • This configuration is easy to implement because only the rib or ribs projecting from the joining faces are to be realized. In addition, this configuration makes it easier to nest body elements.
  • the second body member further comprises a third junction face of which projects at least one third rib defining at least one third groove, each third rib housing at least one of the third channels of fluid circulation.
  • the exchanger then further comprises a third crenellated profile body element comprising a fourth junction face from which at least one fourth rib and at least one fourth groove protrude, each fourth rib housing at least one of the fourth channels of fluid flow, the second and third body members interlocking so that each third rib and each fourth rib are received respectively in a fourth and a third groove.
  • a third crenellated profile body element comprising a fourth junction face from which at least one fourth rib and at least one fourth groove protrude, each fourth rib housing at least one of the fourth channels of fluid flow, the second and third body members interlocking so that each third rib and each fourth rib are received respectively in a fourth and a third groove.
  • each second rib is facing a third groove and in that each third rib is opposite a second groove, which reduces the material used in the construction of the heat exchanger and in particular the material present between the fluid circulation channels, which impairs the heat exchange.
  • At least one of the body members has a free face opposite a junction face, said free face having at least one additional groove facing a rib of the junction face.
  • This additional groove allows "removal" of the material and thus makes the manufacture of the heat exchanger less expensive raw material.
  • the heat exchanger is also lighter and this removal of material prevents unnecessary heat storage at the free face.
  • each rib of each junction face extends on either side of said junction face so as to form in each case a first and a second tooth.
  • the heat exchanger then comprises first and second fluid collectors attached to each body element, the first and second collectors being each provided with holes of a shape adapted to accommodate at least part of said teeth so that the circulation channels of the fluid flow each into a first and a second collector. This is a simple way of connecting the fluid circulation channels to the collectors, which are then connected to the rest of the air conditioning circuit, for example.
  • each first rib of said first body member has bent portions each connecting a tooth to a central portion of the first rib so that said first and second teeth are respectively disposed in planes inclined with respect to said first junction face, this allows to shift the collectors of the plane in which the body of the heat exchanger is located in order to gain space and not to interfere with the support of the second body member coming into interlocking with the first body member.
  • each second rib of said second body member has a bent portion connecting a first and second teeth to a central portion of said second rib so that each tooth is disposed in an inclined plane. relative to said second junction face.
  • each fourth rib of said third body member has a bent portion connecting a first and a second tooth to a central portion of said fourth rib so that each tooth is disposed in a plane inclined relative to said fourth junction face. In this case, there is enough space to accommodate adjunct collectors at the second body member.
  • first and second tooth of the second and third junction faces are respectively received in the same first collector on the one hand and in the same second collector on the other hand.
  • first fluid flow channels and the second fluid flow channels are formed in the first and second grooves respectively so that the first fluid flow channels and the second circulation channels of fluid are aligned. This makes it possible to reduce the gap between the fluid circulation channels in order to improve the heat exchange.
  • each body member is formed as a profiled and integral piece, obtained, for example, by extrusion, which constitutes a simple implementation of the invention.
  • the realization of the body members as one-piece pieces provides the best resistance to pressure possible. Extrusion makes it easy to make the fluid circulation channels.
  • each first rib and each second groove are of jointly selected dimensions in a tight fit.
  • the filler metal is capable of weakening the corrosion resistance of the body and reducing its mechanical resistance to the pressure exerted by the fluids.
  • the heating and cooling of the body elements induce a change in their metallographic structure; these modifications are likely to reduce the resistance to pressure of the exchanger body.
  • the ribs of at least one of the body members may have a trapezoidal or square section.
  • each first rib, each second groove, each first groove and the second ribs are of identical section so that the first and second body members are of identical shape.
  • the body elements are made as identical pieces which are then matched. This reduces costs and facilitates the manufacture of the heat exchanger.
  • the body elements of which each rib has bent portions are bent in the vicinity of their ends to form said bent portions, which allows to bend all the ribs in the same manufacturing process.
