Definitions

  • the invention relates to a condenser, particularly for an air conditioning system of a motor vehicle. It also relates to a device for supporting one or more equipment elements of a front face of a motor vehicle and a heat exchanger equipped with such a condenser.
  • the refrigerant is then passed to a pressure reducer or a calibrated orifice before entering an evaporator where heat exchange between the cooled refrigerant and the pulsed air occurs towards the passenger compartment of the vehicle.
  • the refrigerant, heated at the outlet of the evaporator, is finally returned to the compressor to perform a new thermal cycle.
  • the heat transfer fluid for heat exchange with the refrigerant in the condenser may be outside air.
  • the condenser is placed on the front of the vehicle so as to be traversed by a flow of ambient air produced by the movement of the vehicle or by a fan. This is called an air condenser.
  • the coolant is water with an antifreeze, glycol for example, circulating in a low temperature circuit using an electric pump between the condenser and an external water / air heat exchanger. This is called a water condenser.
  • the invention proposes to overcome these drawbacks and relates to a condenser, in particular for an air-conditioning system of a motor vehicle, comprising a housing and a heat-exchange beam, the condenser being configured to allow a heat exchange between a fluid refrigerant traveling through the beam and a coolant passing through the housing.
  • said housing is made of plastic.
  • the housing for example by molding, by integrating therein several functions such as flanges or others. There is in this way a condenser using a heat transfer fluid that can be liquid having a simplified structure.
  • the invention also relates to a device for supporting one or more elements of equipment of a front face of a motor vehicle, said support device comprising a nozzle capable of accommodating said element or elements and a condenser according to one of any of the preceding claims, the housing of said condenser being attached to said nozzle. According to this embodiment, the condenser is thus integrated into the nozzle.
  • the invention also relates to a heat exchanger comprising a heat exchange fluid exchange bundle with an air flow, an inlet manifold arranged to distribute the coolant in said coolant exchange bundle, an outlet manifold arranged to collect the heat transfer fluid from said heat transfer fluid exchange bundle, said inlet manifold and said outlet manifold each comprising a housing closed by a collector plate, connected to the bundle, said heat exchanger further comprising a condenser as described above, the condenser housing consisting of the housing of the inlet and / or outlet manifold.
  • the condenser is thus integrated in the heat exchanger, the collector advantageously filling the function of condenser housing to guide the heat transfer fluid.
  • the air conditioning and exchange circuits are advantageously merged within the same unit which limits the bulk while maintaining optimum performance.
  • the water condenser is mounted in the front face of the vehicle, in the manner of an air condenser, without however increase the size of the front face.
  • Another advantage of this solution is that it makes it possible to keep air conditioning circuit topologies relatively similar to those with air-cooled condensers of the state of the art. This avoids having to design an entirely new architecture for the use of a water condenser.
  • the collector comprising a U-section housing
  • the refrigerant exchange bundle is mounted integral with a first branch of the U.

  • the heat transfer fluid can circulate in the beam and around the beam so as to promote heat transfer by thermal conduction.
  • the refrigerant exchange bundle includes an inlet manifold and a coolant outlet manifold extending externally to said housing.
  • the refrigerant fluid is advantageously introduced and discharged via the housing which allows to form an air conditioning circuit by connecting to said inlet and outlet piping of refrigerant which are accessible.
  • At least one of said pipes comprises a threaded portion. More preferably, a fixing nut secures said tubing to said housing.
  • the threaded portion can advantageously fulfill a sealing function of sealing the coolant exchange bundle to the housing and allow connection to the air conditioning circuit.
  • the collector comprises a heat transfer fluid duct opening into said volume.
  • the coolant can be introduced / removed from the collector before / after exchange with the refrigerant beam.
  • the condenser is defined by the outlet manifold.
  • the cooling fluid can be cooled with a coolant cooled by the exchanger. This advantageously improves the exchange performance of the refrigerant beam.
  • the heat exchange fluid exchange bundle extends orthogonally to the refrigerant exchange bundle.
  • the exchange performance of the coolant beam is advantageously optimized because of the cross traffic of the two fluids.
  • the heat exchange fluid exchange bundle comprising a plurality of heat transfer fluid circulation tubes
  • the refrigerant exchange bundle extends opposite the mouth of the tubes of the heat transfer fluid exchange bundle.
  • the circulation velocity of the heat transfer fluid is then high when it circulates in the refrigerant beam, which improves the heat transfer by thermal conduction.

  • the collectors 111 a, 111 b for the heat transfer fluid are located at the level of said collecting elements 117.
  • the heat transfer fluid can thus be distributed between the tubes 115 and then travel the beam between said collectors 111a, 111b by being channeled between said tubes 115. It is thus avoided that a portion of the heat transfer fluid passes directly from the inlet 113a at the outlet 113b of the exchanger without exchanging with the refrigerant.
  • said first zone 107 is provided at the level of the tubes 115 and said second zone 109 is provided at the level of the collector elements 117.
  • Said housing 103 has, for example, inlet pipes 119a and / or outlet 119b for the heat transfer fluid, made of material. They open into the collectors 111a, 111b.
  • Said housing 103 may also have reinforcing ribs 121, made of material.
  • Said ribs 121 have, for example, a cross configuration.
  • the housing 103 has a substantially parallelepipedal shape and the ribs 121 are parallel to the edges of the housing.
  • Said housing 103 may also have fixing flanges 123 of the condenser to a support, said flanges being made of material.
  • Said fastening flanges 123 are located, for example, at one or more reinforcing ribs 121, in particular, between two said ribs 121.
  • the housing 103 is closed, for example, by a cover 125, in particular made of metal, which can be crimped on this one.
  • the cover defines, for example, an end plate of the beam 105.
  • the beam 105 is integral with the cover 125.
  • the heat exchange bundle 105 has, in particular, inlet-outlet pipes 127a, 127b opening through the cover 125.
  • these pipes 127a, 127b communicate with a bottle 129 which can be carried by the cover 125.
  • a bottle 129 which can be carried by the cover 125.
  • This is a bottle used, in a manner known to those skilled in the art, to define a reserve volume of refrigerant. It may also be used to filter it and / or ensure that it is placed in contact with a desiccant placed inside it.
  • Said bottle can be further configured to allow phase separation, to eliminate any parts still vapor phase of the refrigerant at the outlet of the condenser before it continues its journey.
  • the refrigerant thus enters the condenser, through the inlet manifold 127a, passes through the collector elements 117 located at a first end of the tubes 115, enters the tubes 115 that it travels, opens into the collector elements 117 located at the other end of the tubes 115 and then exit the condenser through the outlet pipe 127b.
  • the condenser is fixed, for example, to a nozzle of a support device of one or more equipment elements of a front face of a motor vehicle, said nozzle being provided capable of accommodating said one or more equipment elements.
  • a nozzle incorporating a stator of a ventilation device.
  • Said nozzle is also made of plastic, the fixing of the condenser is simplified.
