Definitions

  • the invention relates to a heat exchange module of the type described in the document FR 2 809 486 , corresponding to the preamble of claim 1, this module consists of a main heat exchanger and at least one secondary heat exchanger mounted parallel to the main heat exchanger so as to form a single unit whose exchangers are crossed by a single air flow.
  • the invention relates to a heat exchange module consisting of a main heat exchanger and at least one secondary heat exchanger, the main heat exchanger and the secondary heat exchanger comprising a body provided with tubes. circulating fluid and at least one manifold provided with a perforated manifold of receiving holes of the tubes of the body of the exchanger, the module comprising cooling fins common to the main exchanger and at least one secondary exchanger, these fins being mounted on the tubes of the main heat exchanger and projecting from the latter substantially perpendicularly to its plane, the parts of the fins projecting from the main heat exchanger having receiving cutouts of the secondary heat exchanger.
  • a heat exchange module of the type described above may consist of a cooling radiator of the vehicle engine and one or more secondary exchangers, usually a condenser forming part of the air conditioning circuit of the passenger compartment of the vehicle. automobile or oil radiator.
  • the tubes of the secondary heat exchanger (or secondary heat exchangers) are forced into the cut-outs of the common fins. These tend to deviate. Therefore it is necessary to maintain them by means of a comb-shaped tool inserted between the tubes of the main exchanger. This operation leads to leaving a clearance of several millimeters between the collector of the main exchanger and the first fin. This results in several disadvantages.
  • a part of the tubes is devoid of fins, which decreases the heat exchange capacity and therefore the efficiency of the exchanger.
  • the game left between the face outer of the manifold and the first fin can be source of corrosion of the tubes.
  • the tubes must be flared by means of a flaring punch to prevent tearing of the manifolds under the effect of the pressure of the cooling circuit fluid and the mechanical stresses to which the boxes collectors are subject.
  • the invention specifically relates to a heat exchange module that overcomes these disadvantages.
  • the manifolds or boxes of the main heat exchanger comprise at least one projection extending towards the said secondary heat exchanger or to cooperate with the collector or boxes of or said secondary exchangers and with said fins so as to structure said module, a seal being disposed outside the collector of the manifold.
  • the seal is supported on the first fin of the main exchanger, so that it effectively protects the tubes of the latter against the risk of corrosion in this generally critical area on the mechanically assembled exchangers, using a gasket. elastomer.
  • a gasket elastomer.
  • the seal mounted outside the manifold does not have this disadvantage.
  • said projection consists of a comb having cutouts for receiving the tubes of the secondary heat exchanger (or secondary heat exchangers, where appropriate), this comb being able to keep tightly the parts of the fins projecting from the body of the main exchanger.
  • the header will have only one comb. If the heat exchange module has only one secondary heat exchanger, the header will have only one comb. If the heat exchange module comprises a secondary heat exchanger on either side of the main exchanger, the header of the main exchanger may include a comb on each of its faces.
  • the comb may advantageously be provided along the entire length of the header of the main exchanger. However, this characteristic is not imperative. The comb could only be provided for part of the length of the header of the main exchanger.
  • the comb is preferably made in one piece with the manifold of the main exchanger, in particular by molding a plastic material.
  • the comb could, alternatively, be made separately from the header and be secured to the latter by any appropriate means.
  • the exchangers of the heat exchange module may have only one manifold, for example if it is equipped with U tubes.
  • the tubes are straight and each exchanger has a collector box at each end of the tubes.
  • each header of the main heat exchanger has a fin holding comb.
  • the comb is supported on the manifolds of the secondary exchanger (or secondary exchangers, if there are several).
  • the manifolds of the secondary exchangers constitute stops that stop the movement of the comb and therefore retain the manifold of the main exchanger.
  • the comb thus makes it possible to ensure the retention of the header box of the main exchanger via the boxes of the secondary exchanger (or secondary exchangers, if necessary).
  • the collector comprises a shoulder that provides space for the seal.
  • the collector is made of plastic.
  • the manifold has a tubular shape of closed section made in one piece.
  • the collector box is closed to both ends with plugs. These plugs can be, in particular, welded by friction or by any other appropriate technique.
  • the manifold comprises a lateral opening closed by a lid.
  • the lid can be welded to the header by any appropriate technique, including friction.
  • This design allows the release of flattened pipes at the base with a connection radius favorable to the flow of the fluid of the exchanger and in addition a reduced header height.
  • the manifold preferably has shapes adapted to receive and fix the nozzle of a motor-fan unit.
  • the heat exchange module of the prior art is composed of a radiator 1 for cooling a motor vehicle engine and a condenser 2 for air conditioning, these two exchangers being generally flat.
  • the radiator 1 and the condenser 2 respectively constitute a main heat exchanger and a secondary heat exchanger.
  • the radiator 1 consists in a known manner of a body 3 made from a bundle of vertical fluid circulation tubes and mounted between two manifolds 4 and 5.
  • the manifolds are arranged along two parallel sides of the body and provided with inlet tubing 6 and outlet (not shown) of the cooling fluid.
  • the condenser 2 also consists of a body 7 made from a bundle of vertical fluid circulation tubes 23 mounted between two manifolds 8 and 9.
  • the manifolds 8 and 9 are arranged along two parallel sides of the 7. They are provided with two inlet and outlet pipes 10 of the refrigerant.
  • the heat exchange module comprises fins 11 common to the cooling radiator 1 and the condenser 2. These fins 11 are shown in more detail on the figure 2 . They are mounted so Conventional on the tubes 22 of the body 3 of the heat exchanger 1. They have extensions 12 projecting, perpendicular to the plane of the exchangers, the side of the secondary heat exchanger 2. The extensions 12 comprise cutouts 13 open in direction of the exchanger 2. These cuts have a shape corresponding to the cross section of the tubes 23 of the condenser 2, which are here flat tubes, and not even that these tubes, so as to receive them. The tubes 23 of the secondary heat exchanger 2 are forced into the cutouts 13 of the fins. This ensures frictional locking between the walls of the tubes 23 and the edges of the cuts 13.
  • the assembly of the exchanger 1 with its fins 11 with the exchanger 2 without fins is carried out as follows.
  • the exchanger 2 is simply pressed against the exchanger 1 by forcing the tubes 23 of the exchanger 2 into the cutouts 13 of the extensions 12 of the fins, which ensures the blocking of the exchanger.
  • the manifold 5 of the main radiator 1 consists of a collector or collector plate (not visible on the figure 1 ) made of metal and having holes for receiving the tubes 22 of the exchanger 1.
  • the manifold 5 further comprises a cover 14, generally made of plastic.
  • the assembly of the cover 14 on the manifold is generally done by means of folded crimping tabs on a peripheral rim of the cover 9.
  • the peripheral rim which surrounds the manifold 9 and which is intended to receive the tabs which allow the crimping of the lid 9 on the manifold increases the size of the cooling radiator 1 and therefore the overall size of the module by imposing the presence of a space between the main heat exchanger and the secondary heat exchanger.
  • a rubber or elastomer seal is disposed inside the manifold 5.
  • This seal comprises tubular parts which engage in the receiving holes of the tubes 22 of the main exchanger 1.
  • the fins 11 must be maintained during the introduction of the tubes 23 of the condenser 2 by a suitable tool inserted between the last fin of the beam and the outer face of the collector. This operation leads to a gap of several millimeters between the collector and the first fin. This results in a reduction of the exchange surface between the air flow through the exchanger and the fins.
  • tubes 22 of the main heat exchanger remain exposed because the tubular portion of the seal can not extend over the entire length for reasons of demolding.
  • the manifold 5 of the main exchanger 1 comprises a comb 28 which, in the embodiment shown, extends over the entire length of the manifold 5.
  • the comb 28 could extend only over a only part of the length of the collecting box.
  • the comb 28 is made in one piece with the manifold 5, preferably by molding a plastic material.
  • the comb could be made separately and secured to the collector box.
  • the comb 28 consists of teeth 29 arranged in pairs and which delimit between them a cutout 30 (see FIG. figure 5 ) whose function is to maintain the first fins during the assembly of the tubes 23.
  • the cutouts 30 are intended to receive the tubes 23 of the secondary heat exchanger 2 when the main exchanger and the exchanger secondary are assembled (see figure 6 ).
  • the comb 28 has a face 31 directed towards the fins 11 and on which they come to bear.
  • the comb 28 fulfills the function which, in the prior art, is held by a special auxiliary tool temporarily introduced during assembly of the tubes 23 of the condenser 2 between the fins 11 and the manifold 5, and more particularly between the fins 11 and the outer face of the collector. Since the use of this tool is no longer necessary, it is no longer necessary to leave a clearance of several millimeters between the first fin and the manifold so that the tubes 22 may have fins along their entire length. .
  • the seal 33 may be disposed outside the manifold 5, on the face of the manifold 35 directed towards the fin bundle 11. This arrangement is advantageous because the seal 33 protects the portion of the tube located between the first fin and the outer face of the manifold 35 against corrosion.
  • a shoulder 37 constitutes a stop for the set of fins 11 so as to avoid compression of the seal 33.
  • the comb 28 has a face 39 directed towards the manifold 8 of the exchanger 2 which bears on this manifold 8.
  • the teeth 29 of the comb 28 thus take up the tearing forces of the manifold 5 under the effect the pressure of the cooling coolant circulating in the tubes 22.
  • the tubes of the main exchanger 1, such as 22, comprise a mechanically flared portion by the introduction of a flare punch. This flaring is intended to prevent tearing collector boxes. Given that these efforts are taken up by the manifolds 8 and 9 of the secondary heat exchanger 2, the flaring of the tubes 22 is no longer justified. Therefore, these tubes can be straight and have a constant section over their entire length. However, they may include a retreint or chamfer 41 at their end to promote their introduction into the joint 33 ( figure 6 ). The fact that the tubes are not flared allows greater freedom in the choice of alloy in which these tubes are made.
  • the manifold 5 is constituted by a tubular form of closed section. It is made in one piece.
  • the collector and the cover which, according to the prior art, are made of two pieces of different materials (steel collector and plastic cover), are, in this embodiment, made in a single molded part made of plastic
  • the header is closed at both ends by plugs 43 ( Figures 3 and 4 ). These caps can be friction welded to the manifold.
  • the manifold is made of plastic material, it can easily include fixing lugs such as 45 which allow to fix it on the chassis of the vehicle. It may also include forms 47 adapted to receive and fix the nozzle of a motor-fan unit (not shown).
  • the manifold 5 also made of molded plastic, consists of a box 51 comprising the inlet and outlet pipes 6 of the fluid.
  • the box 51 also comprises the holes for receiving the tubes 22 of the main exchanger 1.
  • the comb 28 is also formed on the box 31.
  • the latter is closed laterally by a cover 53, which may optionally be plane.
  • the cover 53 is fixed on the box 51 by any appropriate means, in particular by friction welding.
  • the comb 28 could also be provided on the cover 53.
  • This design allows the demolding of flattened pipes at the base with a connection radius favorable to the flow of the liquid and moreover a reduced header height.
