Definitions

  • the invention relates to the field of heat exchangers between two fluids, in particular for cooling an air flow by heat exchange with a refrigerant.
  • the invention relates in particular to an exchanger according to the preamble of claim 1.
  • Such an exchanger is known from the document JP 09113171 .
  • Such heat exchangers are used in the field of air conditioning, for example motor vehicles and are in particular evaporators for a vehicle air conditioning loop. They make it possible to exchange heat between a first fluid, in particular air and a second fluid, for example a refrigerant fluid. They comprise a bundle of tubes, intended for the circulation of the second fluid, arranged in parallel on one or more rows, spacers of entry and / or exit of the second fluid into the tubes and spaces between the tubes for the circulation of the second fluid.
  • Such tubes have, for example at their ends, a fluid distribution zone, also called collecting space, for collecting and distributing the coolant.
  • Each plate is thus provided with a stamp defining the fluid distribution zone in the exchanger and making it possible to establish a connection between two adjacent plates of two successive tubes.
  • These connections ensure the stability of the structure, to ensure the seal between an internal volume of the heat exchanger and the surrounding environment, that is to say between the internal volume of the tubes and the air. They also allow the coolant to circulate in the exchanger from one tube to another.
  • the tubes Between their ends, the tubes have a central part, called tube body, guiding the refrigerant fluid from one end to the other.
  • Said tubes being in contact with each other only at their ends, there are spaces between the bodies of two adjacent tubes. These spaces are used to circulate the first fluid through the heat exchanger to exchange heat with the second fluid flowing inside the tubes.
  • the exchanger also comprises an inlet pipe carrying the cooling fluid to the tubes, connected to the tubes via an inlet spacer and an outlet pipe discharging the refrigerant from the tubes and connected thereto by the intermediate of an exit spacer.
  • the document FR2929388A1 proposes a thickness of the plates forming the tubes less than 0.3 mm.
  • a problem is created when said tubing or pipes are subjected to mechanical stresses related, for example, to the operation of the vehicle. These constraints are then reflected on the plates of the exchanger via the spacers.
  • the plates being of thickness less than 0.3 mm, they deform under the effect of the stress, which can cause a rupture between two adjacent plates, thus creating a leak allowing the coolant to escape.
  • the aim of the invention is to remedy the aforementioned problem by proposing to improve the resistance to stresses at the level of the connections between two adjacent plates while retaining the use of plates less than 0.3 mm thick.

  • the multiplicity of plates comprises a fluid circulation portion interposed between two plate ends, the male stamping of the first and second plates being made at at least one end of said plates.
  • the first and second plates defining a duct or the assembly formed of a plate of a duct and a side plate each comprise at one end both a stamped male and a stamped female. In this way, the reinforced connection between the plate and the insert is doubled and its strength is thus improved.
  • each end of the plates comprises both a stamped male and a stamped female.
  • the first twenty-five per cent of said width from one side of the exchanger are configured so that the male stamp of each plate enters the female stamp of each insert, in order to ensure interlocking between the plates.

  • the insert 5 may also be provided with a female stamp 9 and a male stamp 4 in the case where the first 3 and the second 4 plates also have a male stamp 8 and a corresponding female stamp 9 .
  • the insert 5 is made of a material of a plate and can be of a first plate 3, a second plate 4, a first plate of side 15 and / or a second side plate 16. It is in this case made of the same material as the plate from which it is derived, that is to say that it is made unitarily with the plate, forming with she a block of unique material.
  • Such a configuration of the insert 5 is reflected on the plate on which it is located by, in particular, the presence of a shoulder at which the insert 5 starts, that is to say close to the end of the plate on which the insert 5 is located.
  • the insert 5 is made of material of a plate, it has the same shape as that of the insert 5 attached to the plate as described above.
  • two adjacent tubes 2 whatever their position in the exchanger 1, comprise a first plate 3 of one of the tubes 2 which is assembled with a second plate 4 of a other tubes via an insert 5. Therefore, one of the first and second plates 3, 4 comprises a 5 connecting insert so that the stamped male or female 8 or 9 of a tube is configured to penetrate or cover respectively the stamped female or male 9 or 8 of a tube 2 which is directly adjacent thereto.
  • each of the links between the tubes 2 comprises an insert 5.
  • some of the connections between the plates comprise an insert 5, for example certain connections situated at the level of the first twenty-five percent of the width of the exchanger 1, starting from the first side of the exchanger 1 , or only between the first and second side plates 15, 16 and their plates 3, 4 directly adjacent.

  • the figure 3 further illustrates an aspect of the invention wherein the female stamping 9 of the insert 5 has a tubular sector 21 whose central axis is directed in the direction ox. It ends with an edge 22 extending in the extension of the tubular sector 21 and which covers the male embossed 8 of the first plate 3 of the first tube 2a. It is understood here that the edge 22 overlaps at least in part the male stamp 8.
  • This edge 22 and this tubular sector forms a unitary unit. In practice, it is a tube of internal diameter or equal to the outer diameter of the male embossed 8.
  • This male stamp 8 of the first plate 3 or the second plate 4 also has a tubular sector 31 configured so that it can penetrate into the tubular sector 21 of the insert 5 but ending with a bottom 33 which extends in a plane perpendicular to a central axis of the tubular sector 21, that is to say in the direction ox.
  • the bottom 33 is, for example, provided with an opening 10 through which the fluid passes. It is through these tubular sections 21 and 31 that the fluid will flow between two adjacent tubes 2 inside the exchanger 1.
  • each tube 2 is formed by a first half-tube 2 'and a second half-tube 2 ", separated from one of the other by the waterproof section.
  • Each plate must be provided with two stampings delimiting the distribution zone 6, 7 of fluid in the exchanger 1.
  • the first plate 3 and the second plate 4 have both a male stamp 8 and a female stamp 9, at least at one end of the plates, and in particular to both.
  • the fluid can circulate between the half-tubes 2 'of two adjacent tubes 2 and / or between the half-tubes 2 "of two adjacent tubes 2.
  • the figure 5 illustrates a first plate 3 and a second plate 4 belonging to two adjacent tubes 2 or a first plate 3 and a first side plate 15, shown here side by side.
  • the first plate 3 located to the left of the figure 5 is stacked on the second plate 4 or on the first side plate 15 to the right of the figure by rotating 180 degrees about the axis A.
  • a stamped male 8 and a female stamped 9 of the insert 5 located at the end of a second plate 4 or a first plate 15 a stamped female 9 and a stamped male are matched 8 located at the corresponding end of the first plate 3 adjacent. This strengthens the connection between the two plates against the various constraints that can be exerted in the plane oyz.
  • each plate is identical, that is to say embossed by the same press footprint.
  • the logistics are thus reduced because one uses a single type of plate that is returned to achieve the first and second plate according to the invention.
  • Each face of the exchanger is also reinforced, which makes it possible to provide a reinforcement according to the invention in a simple manner simultaneously to the two pipes, that is to say inlet and outlet pipes.
  • the heat exchangers according to the invention find a particular application in the heating, ventilation and / or air-conditioning installations of motor vehicles. It can also be cooling radiators of the engine, interior heating radiators, condensers, gas coolers or air conditioning system evaporators, charge air coolers and oil exchangers.
