Definitions

  • the invention relates to the field of heat exchangers according to the preamble of claim 1.
  • EP 1,870,658 discloses such an exchanger.
  • the invention relates more particularly to heat exchangers capable of being traversed by a refrigerant fluid having a relatively high operating pressure, as is the case of natural gases such as carbon dioxide designated by CO 2 , having a pressure of superior operation to the refrigerant gases used in state-of-the-art solutions.
  • Such heat exchangers find particular application in motor vehicles. They can in particular constitute a gas cooler in which the refrigerant fluid such as CO 2 is cooled by a second fluid, such as liquid. Conversely, the second fluid can be cooled by the first fluid, for example in gaseous form, the heat exchanger is then commonly designated by “Water chiller” in English.
  • Such heat exchangers can in particular be used in the thermal regulation of one or more batteries of an electric or hybrid vehicle.
  • the thermal regulation of the batteries is an important point because if the batteries are subjected to too cold temperatures, their autonomy can decrease strongly and if they are subjected to too high temperatures, there is a risk of thermal runaway which can go up to destruction of the battery, or even of the motor vehicle.
  • a heat transfer fluid in general cooling liquid comprising a mixture of glycol water, which circulates within a heat exchanger in contact with the battery or batteries.
  • the coolant can thus bring heat to the battery or batteries to heat them, this heat having been absorbed by the coolant for example during the heat exchange with the CO 2 circulating in the gas cooler.
  • the coolant can also, if necessary, absorb heat emitted by the battery or batteries in order to cool them and evacuate this heat at the level of one or more other heat exchangers.
  • Such heat exchangers can also be used like any other gas cooler in an air conditioning system.
  • Heat exchangers are known, for example, comprising a stack of plates allowing the circulation of the first fluid, such as the refrigerant or refrigerant gas, and of the second fluid such as the coolant.
  • the plate heat exchangers known from the prior art do not make it possible to withstand such high pressures.
  • heat exchangers are also known from the prior art comprising a stack of tubes connected together by at least one collector of the first fluid, in particular the coolant on each side of the tubes, and the second fluid, for example in liquid form, can circulate around the tubes in an envelope connected to a water box.
  • the heat exchangers can in particular be assembled by brazing.
  • a brazing material is generally provided on different elements of the heat exchanger.
  • the brazing material which melts can block the channels in which at least one fluid is intended to circulate, in particular the refrigerant.
  • the present invention aims to improve the solutions of the state of the art and to at least partially resolve the drawbacks exposed above by proposing a heat exchanger whose assembly by brazing is improved.
  • the spacers respectively have at least one tank capable of collecting the coating during the brazing of the heat exchanger, each tank being arranged on one end of a spacer and facing one end of a tube d heat exchange, so as to prevent the coating from clogging said at least one circulation channel of the heat exchange tube during brazing of the heat exchanger.
  • the coating present to ensure the junction between the elements of the heat exchanger during assembly does not run the risk of blocking, when it melts, the circulation channels of the first fluid.
  • the coating which migrates during brazing flows into the reservoirs opposite the ends of the heat exchange tubes instead of risking entering the circulation channels of the first fluid accessible at the ends of the heat exchange tubes.
  • the heat exchanger may further comprise one or more of the following characteristics taken alone or in combination.
  • the spacers respectively have at least one reservoir on each face opposite a heat exchange tube.
  • the heat exchanger thus comprises a stack of simple elements, namely frames and heat exchange tubes in which the first fluid circulates, such as the coolant, inserted in the first frames and between which the second fluid circulates. only coolant.
  • the superimposed frames allow the flow path of the first refrigerant to be created, when the frames are brazed together, and likewise, the superimposed frames create the coolant flow path, in particular on two opposite sides of the bundle d 'heat exchange.
  • the frames designate a part, or an assembly of parts, which can be rigid, delimiting a closed or not space. In this space can be positioned, in our example, heat exchange tubes.
  • the heat exchange bundle which comprises a plurality of heat exchange tubes, is distinct from the frames.
  • Such a heat exchanger has better mechanical strength compared to the solutions of the prior art and very good resistance to high pressures, in particular due to the circulation of CO 2 as refrigerant.
  • the reservoir is produced by reducing the material of an interlayer, or intermediate frame.
  • the reservoir is produced in the form of a groove extending substantially perpendicular to the direction of flow of the first fluid in the heat exchange tubes.
  • the reservoir extends opposite the entire end of a heat exchange tube, for example over the entire width of a heat exchange tube produced in the form of a flat tube.
  • the first receiving frames respectively have at least one recess at an interior corner receiving a corner of a heat exchange tube, for the flow of the coating during brazing of the heat exchanger, so as to prevent the coating from clogging the channels of the heat exchange tubes.
  • the width of the step is substantially equal to the width of the groove.
  • This arrangement corresponds to the arrangement of the elements in the mounted state in a motor vehicle in particular.
  • the invention relates to a heat exchanger 1 in particular for a motor vehicle, for a heat exchange between at least a first fluid and a second fluid.
  • the first fluid can enter the heat exchanger 1 in gaseous form and the second fluid in liquid form.
