Definitions

  • the present invention generally relates to a heat exchanger, in particular for use as a charge air cooler or exhaust gas cooler in an internal combustion engine.
  • Such heat exchangers for use as charge air or exhaust gas coolers conventionally have two tanks, which are spaced apart and are fluidically connected by means of a plurality of pipes (e.g. flat pipes) forming a pipe block.
  • the charge air to be cooled then flows from one tank, through the pipes, to the other tank.
  • the pipe block is surrounded by a separate piece of sheet metal, which is closed circumferentially around the pipe block and forms a cover (or casing) so that a chamber is formed between the two tanks, through which chamber the pipes run.
  • This casing is provided with an inflow and outflow for a coolant.
  • the pipes are held in place at both ends by means of a header plate (or pipe plate) with through-openings for the pipes.
  • the tanks then form a type of hood, which is closed on its broad side by the header plate.
  • the pipes are inserted in the header plates and the cover is next arranged around the pipes.
  • the tanks are then mounted on the pipe block.
  • Such heat exchanger is e.g. known from US 2008/0289833 or FR2251794 .
  • the header plates conventionally have two functions: they maintain the pipes; and they serve for the fastening of the tanks and cover.
  • the pipes, cover and header plates are typically made from aluminium. This thus allows for soldering or brazing parts together.
  • the header plates may have peripheral edges projecting in such a way as to run in or over the tank, respectively the cover; and the soldering may be carried out along such projecting edges.
  • joints based on fitting and brazing are not easy to achieve. If the tank is not made from aluminium but plastic, the header plate can be provided with clinching tabs to be clamped on the tank.
  • WO2010/003807 discloses a heat exchanger having a cover with integrated fastening means for the tanks.
  • the object of the present invention is to provide a heat exchanger that can be assembled in a simple and reliable way.
  • a heat exchanger in accordance with the present invention comprises a pipe block with a plurality of pipes, the pipes opening at both ends in a respective tank for a first fluid.
  • the pipes are maintained at both ends by a respective header plate having a number of through-openings therein for the pipes.
  • a cover extends between the tanks and laterally essentially surrounds the pipe block.
  • Fastening means are provided about at least one pipe block end, preferably at both ends, that are adapted to maintain the respective tank in place on said pipe block.
  • the fastening means take the form of mechanical locking means that are integrated in the cover.
  • the present heat exchanger has mechanical locking means for the tanks that are incorporated in the cover.
  • the external elements constituted by the tanks and cover that provides a simple and reliable mounting.
  • the mechanical locking means are preferably integrally formed in one piece with the cover. However, one could assemble the mechanical locking means to the cover before assembling the heat exchanger, but the mechanical locking means for the tanks are not provided by the header plate.
  • the mechanical locking means comprise by a bent edge region of said cover that is adapted to receive therein a foot region of the respective tank.
  • the bent edge region comprises clinching tabs that are clamped onto the foot region of the respective tank.
  • the cover is namely outwardly bent to form a circumferential border surrounded by a projecting edge terminating with the tabs. This allows using conventionally designed plastic tanks that have in their foot region a peripheral shoulder on which the tabs can be clamped.
  • the header plate is seated on the circumferential border of the locking means.
  • the latter comprises locking tabs outwardly protruding from the rim of the header plate and engaging into holes in the cover at the level of the mechanical locking means, e.g. in the projecting edge.
  • the mechanical locking means are incorporated in the cover so as to be able to directly fasten the cover, not through the header plates.
  • Various embodiments of such mechanical locking means may be devised by those skilled in the art.
  • the foot region of the tanks may be provided with interlocking means cooperating with the mechanical locking means of the cover.
  • the tank/cover joint may be designed so that the tank fits around the cover with its locking means, although for sealing purposes it is preferable that the cover locking means surround the tank's connecting region.
  • the cover may be comprised of two parts, or more parts, in order to facilitate the assembly.
  • the cover is preferably provided with at least one inlet orifice and one outlet orifice for the second fluid that flows around the pipes.
  • the fluid to be cooled is the first fluid circulating through the tanks and pipes, while a liquid coolant is the second fluid circulated in the chamber defined by the cover.
  • Fig.1 shows a heat exchanger 10 in accordance with an embodiment of the present invention. It comprises a pair of tanks 12, 12' that are mounted at opposite ends of a pipe block 14.
  • the pipe block 14 comprises a plurality of flat pipes 16.
  • the flat pipes 16 are maintained in a parallelly spaced relationship by means of header plates 18 arranged about both ends of the pipes 16.
  • the header plates 18 have a shape matching the cross-sectional shape of the pipe block 16 (here rectangular) and are provided with a set of elongate through-openings 20 that receive the pipe ends, the number of through-openings 20 corresponding to the number of pipes 16 to be maintained.
  • Reference sign 24 indicates the rim of the header plate 18 while webs separating two through openings are indicated 26.
  • a first fluid may thus flow from one tank 12, 12' to the other through the flat pipes 16.
  • the tanks 12, 12' here have a conventional hood-shape.
  • the pipe block 14 is laterally surrounded by a cover 22, which in this embodiment is subdivided into two cover halves 22' and 22".
  • the cover 22 further extends essentially over the whole height (in axial direction of the pipes) of the pipe block 14.
  • the cover 22 Upon assembly, the cover 22 thus defines a chamber for a second fluid, through which the flat pipes 16 run, that is closed in the axial direction of the pipes 16 by the rim 24 and webs 26 of the header plates 18.
  • the dimensions and shape of the cover are thus designed so as to provide such closed chamber for the flat pipes 16.
  • Reference sign 30 indicates a connector 30 is fitted in an orifice in cover half 22' for introducing the second fluid into the chamber around the pipes 16.
  • the other cover half 22" has a similar orifice though which another connector 30' is fitted for the exit of the second fluid.
  • cover halves 22 and 22' are provided with lateral cutouts 23 that allow compressing the pipes 16 during assembly.
  • the gas to be cooled is the first fluid that flows from the tank 12 with two inlet orifices 13 to the second tank 12' with one outlet orifice 13', through the flat pipes 16.
  • a liquid coolant is thus used as second fluid and circulated inside the chamber (defined by the cover 22) around the flat pipes 16.
  • the cover 22 comprises at both ends integrated mechanical locking means that are adapted to maintain the respective tanks 12, 12' in place on the pipe block 14.
  • mechanical locking means are advantageously integrally made in one piece with the cover 22 and designed to cooperate directly with the tanks 12, 12' to fix them firmly on the pipe block 14.
  • the mechanical locking means is formed at the upper end of the cover 22 by a bent end region that is adapted to receive therein a foot region 32 of the tank 12, 12'.
  • the bent end region actually comprises a multiplicity of peripherally distributed clinching tabs 34 that are folded to rest on the foot region 32 of the tank 12.
  • the bent end region preferably takes the following shape.
  • the cover 22 describes, first, an outward bend to form a circumferential border 36 and describes a second bend to form a projecting edge 38 extending in direction of the tank 12 and terminating with the clinching tabs 34.
  • the first circumferential border 36 forms a lateral surface 37, transversal to the axial direction of the pipes and cover (preferably substantially perpendicular thereto), while the projecting edge 38 preferably projects parallel to the axial direction of the pipes 16.
  • the rim 24 of each header plate 18 rests on the lateral surface 37 of the locking means.
  • the rim 24 comprises a peripheral shoulder 40 that supports an annular gasket 42.
  • the foot region 32 of each cooling tank compresses the annular gasket 42 onto the shoulder 40 of the rim 24.
  • the header plate 18 preferably comprises a number of locking tabs 46 laterally protruding from the rim 24 and engaging into corresponding slots 48 provided in the cover 22, e.g. holes arranged in the raised edge portion 38.
  • the tabs 46 may be bent upon insertion in the respective slots 48. This provides a mechanical locking of the header plates 18 in the cover 22, which cannot move in transversal nor axial directions.
  • the tabs 46 are preferably "expanded", which means that they are subjected to plastic deformation to increase their width; this can be done by flattening or stamping the tabs 46, as it is known to those skilled in the art.
  • the tabs 46 will further be bound to the cover 22 during the brazing process.
  • the pipes 16, header plates 18 and cover 22 are made from aluminium or aluminium alloy while the tanks are made from plastic.
  • the tanks may alternatively be made from aluminium or aluminum alloy.
  • the metal parts may advantageously be provided, as it is known in the art, with a brazing cladding, i.e. a thin layer of a metal having a lower melting point than the parts themselves.
  • the foot region 32 of the tank 12, 12' has a conventional S-shape, forming a peripheral shoulder 33 on which the tabs 34 can be easily clamped.
  • the locking means integrated in the cover 22 allow an easy fastening of conventionally-designed plastic or aluminium tanks.
  • the tank connection region may be provided with locking means cooperating with the locking means of the cover 22.
  • the tanks could be provided with tabs or other projections that would lock into holes or recesses in the cover. In designing such interlocking means, it is of advantage to provide for a blocking of the header plates by axial compression, as in the shown embodiment.
  • a turbulator plate 31, as shown in Fig.7 may e.g. be placed between every adjacent pair of flat pipes 16.
  • such plates 31 may take the form of an aluminium sheet with staggered corrugations stamped into each side to enhance the heat exchange efficiency.
  • Other kinds of measures to control the flow of coolant in the chamber may be implemented.
  • Turbulator devices may also be inserted in the flat pipes.
  • the pipe block may consist of two or more rows of superposed flat pipes.
  • the header plates would be adapted to have corresponding rows of through-orifices.
