Definitions

  • the radiant fin heat exchangers that are being manufactured are formed using welded fins, forks and elbows.
  • a set of fins arranged parallel one behind the other is used, each of which has a series of orifices in the direction along the longitudinal axis of the fin so as to define thus, in the direction perpendicular to the fins, alignments between the orifices of the different fins.
  • the corresponding straight sections of the tube through which the refrigerant must circulate are passed through these orifices.
  • the invention proposes a new heat exchanger which has the particularity of being constituted by bundles of elementary or unitary fins. That is, each fin has only one through hole for the coolant tube.
  • a second particularity of this heat exchanger lies in the fact that the tube inside which the refrigerant will circulate is a unique whole and that it is not formed of segments joined by elbows.
  • This new heat exchanger takes place by first forming bundles of individual fins.
  • the subject of the invention is a heat exchanger as well as the process for manufacturing this exchanger.
  • the heat exchangers are constituted, as shown diagrammatically in FIG. 1, by means of a series of radiant fins a , each of which has a series of orifices arranged along its longitudinal axis of so that, by arranging a series of fins juxtaposed between them according to parallel planes, the orifices of the different fins a are aligned, thus making it possible to thread sections of rectilinear tubes t whose ends are connected by welded elbows c for define in this way the corresponding circuit in which the refrigerant will be circulated.
  • each radiant fin designated by the reference 2 in FIG. 2 is of elementary or unitary nature, with a single orifice 2.1 provided with a self-separating collar 2.2 which delimits the spacing between the different fins 2, when they are placed one behind the other in packages 3, see FIG. 2.
  • the materials which can be used for the production of the elementary fins 2 can be all those which are interesting by their properties, from the thermodynamic, mechanical and economic point of view, such as aluminum, iron, copper, plastics, etc.
  • each elementary fin 2 will be that required by the construction of the final exchanger, the fin may be round, square, rectangular, polygonal in general, including with mixed contour and the dimensions will be variable, depending on the characteristics of the exchanger.
  • the different packets 3 of elementary fins 2 are arranged aligned with one another, in the desired number in each case and, through the orifice 2.1, a single tube 1 previously straightened is inserted.
  • This tube 1 constitutes the conduit for the refrigerant and can be made of material such as copper, aluminum, iron, plastics, etc., and its cross section can have a round, elliptical, polygonal configuration, etc.
  • the packages 3 are thus fixed on the tube 1 and at a mutual spacing such that there remains in the tube 1 free zones which are those which correspond to the zones to be bent.
  • the tube 1 is bent, which can be done both without filling and with filling which avoids undesirable deformations.
  • FIG 3 there is shown a curvature of the tube 1 which defines a flat coil, so that on the element thus configured, there are side flanges 4 provided with an orifice 4.1 for the ends of the tube 1 and grooves 4.2 for the bent areas of the tube 1.
  • the side flanges 4 can be made of plastic, aluminum, iron, etc. and, when they have been put in place, the heat exchanger is defined as shown in FIG. 1.
  • a battery is obtained having a parallel geometry , and we have omitted to represent the corresponding couplings of the inlet and outlet manifolds, with biconical fittings, since these are conventional elements.
  • FIG. 7 another possible variant of an angled or helical coil is presented, which is produced with six packages 3 of fins 2, so that two sets of three packages 3 are obtained which meet then to define an elementary battery with parallel geometry.
  • the different basic batteries can be assembled together using the corresponding fittings.
  • the configuration of the elementary batteries can vary without being sorted out for that of the principle of the invention, which basically lies in the realization of the exchanger starting from elementary fins 2 having a single orifice 2.1 and arranged in packages 3 through which is threaded a single tube 1 which is then bent of the desired way to form the heat exchanger.
