Definitions

  • the present invention relates to an atmospheric exchanger, and more particularly to an atmospheric exchanger intended to be used in particular with a heat pump device for space heating or air conditioning.
  • the document FR 2 566 107 describes an atmospheric exchanger according to the preamble of claim 1, with an inlet and a heat exchanger outlet respectively connected to a supply pipe and to a pipe for discharging a heat transfer fluid, comprising several identical unitary exchanger units which are each in the form of a panel having at least one internal serpentine tubular passage for the circulation of the coolant, said serpentine inner tubular passage having projecting end pieces sealingly connected by welding to the respective end tips of the serpentine internal tubular passages of the adjacent panels.
  • Atmospheric exchangers are intended to be placed outdoors.
  • the unitary heat exchanger modules are made of plastics material and are molded by extrusion blow molding. The different unitary heat exchangers are then assembled to each other in the workshop, by welding by means of a heating mirror device.
  • the exchanger of the document FR 2 566 107 is packaged and transported to its installation site.
  • Such an assembled exchanger is relatively fragile and bulky, which makes its transport delicate so as not to damage it. And any damage suffered by one of the exchanger unit modules renders the exchanger inoperable in its entirety.
  • the exchanger inevitably undergoes dimensional variations by expansion and shrinkage depending on the external temperature to which it is subjected. It can then occur mechanical stress concentrations at the level of the links between the different unitary modules exchangers, causing breaks and the appearance of leaks, and making unusable the exchanger in its entirety. In this respect, it has been found that the solder joint does not provide sufficient reliability to guarantee satisfactory operation in the long term.
  • the documents FR 1 190 414 and GB 1 305 464 describe a central heating radiator constituted by a stack of elements each comprising tubular structures of male and female connection.
  • the connection of two adjacent elements is done by interlocking and then respectively solder or solder tubular structures male and female connection.
  • the document GB 2,275,005 describes an end-to-end connection of two tubular structures by crimping.
  • the document FR 2 918 165 describes a connection of tubular structures of male and female connection by simple interlocking or snap-fastening.
  • a first problem proposed by the invention is to design an atmospheric exchanger for heat transfer liquid, able to withstand more effectively the thermal and mechanical stresses due to the variations of the external temperature and in particular to the successive expansion and withdrawal phenomena caused by these variations in temperature.
  • temperature inexpensive, having a large exchange surface, easy to manufacture and transport, and can be easily and quickly adapted to lower energy requirements of each site to equip.
  • the invention aims to design an atmospheric exchanger comprising a plurality of identical exchanger unit modules assembled and connected to each other in a simple, removable and interchangeable manner, limiting or eliminating any risk of heat transfer fluid leakage.
  • Such an atmospheric exchanger is easy to pack and transport to an installation site without risk of damage because it can be brought in spare parts packaged and protected individually.
  • connection and fixing means ensuring the connection and the fixing of the unitary modules exchangers to each other, to add or remove a number of unitary modules exchangers according to the needs of the site to be filled.
  • This exchanger makes it insensitive to the risk of rupture resulting from expansion and removal, thanks to the deformation capacity of the material.
  • the particular structure of the locking connection means guarantees a satisfactory seal, thanks to a sufficient resistance to internal overpressures.
  • the experiment has proved withstand at pressures of the order of 2500 hPa, much higher than the holding of a mirror weld (of the order of 500 hPa).
  • tubular male and female connection structures When connecting two exchanger unit modules, the tubular male and female connection structures can be connected to each other by interlocking and then locked by the reported locking pieces.
  • Such a connection method is simple, fast and easy to perform by a technician at the installation site itself.
  • connection means ensure the connection and attachment of the unitary modules exchangers to each other detachably.
  • the tubular connection structures can be in one piece with the corresponding module body.
  • a disadvantage may be that the module body is then of complex shape, more difficult to mold.
  • the tubular connection structures are each constituted by a male or female plastic connection element, with an external connection section having radial locking projections and forming the projecting portion of the tubular structure of connection, and with an internal fixing section with anchoring asperities and overmolded in the corresponding module body.
  • the overmoulding ensures a satisfactory mechanical strength, without risk of separation of the connecting element, and without the risk of occurrence of a leak.
  • the connecting elements constitute separate parts that can each be easily made by plastic molding, whereas the module body itself, of greater volume, can be produced by extrusion blow molding of plastic material, the connecting elements constituting inserts placed in the mold before extrusion of the plastic material to achieve the exchanger unit module body. After constitution, the assembly can withstand without degradation the necessary mechanical stresses, in particular the internal overpressures of the order of 3000 hPa.
  • the axial clamping ensures a good sealing of the connection after mounting, by compressing the annular sealing gasket, which makes it possible to hold the internal overpressures that can occur during use, without the appearance of leaks.
  • the exchanger unit modules must be held together, away from the ground or support plane.
  • the exchanger comprises support means comprising two support posts with feet and on which rests at least one spar on which are threaded and rest several connected exchange unit modules.
