Definitions

  • the invention relates to new heat exchangers which can be used in particular for exchanges between two fluids, for example between a liquid and a gas and a method for their production.
  • Liquid-gas heat exchangers generally comprise a set of tubes which are substantially parallel to each other through which the liquid participating in the exchange flows, the gas participating in the exchange circulating between the tubes, generally in a direction perpendicular to the axis of the tubes.
  • each tube can be provided with a plurality of fins, which consist of plates of various shapes arranged around the tube throughout its length, generally in planes substantially perpendicular to the axis of the tube.
  • the fins have the drawback of providing the gas flow transverse to the axis of the tubes with a contact surface such that, even if it increases the efficiency of the heat exchange, it also causes significant pressure losses. for the gas flowing in contact with it.
  • exchangers comprising ds batteries of parallel tubes, arranged in several rows, in which each tube is connected to the two adjacent tubes of the same row by a fabric of heat conductive material, in thermal contact with each of the two tubes along a generator thereof.
  • the heat exchangers of the present invention can be defined in general in that they comprise a plurality of substantially parallel tubes which can be associated in at least one row, for the circulation of a first fluid participating in the exchange (more particularly a liquid), the second fluid (more particularly a gas) circulating outside the tubes in a direction generally perpendicular to the direction of said tubes and characterized in that each tube of one of said rows is connected to the two adjacent tubes of the same row (except for the extreme tubes of the rows, which have only one adjacent tube in the same row) by an expanded metal plate secured or made integral with each of the two tubes it connects, the along a generator thereof;
  • these heat exchangers being further characterized in that the plates connecting the tubes are formed in one piece from one end to the other of the same row of tubes, this piece consisting of a strip of expanded metal 1 ( Fig.
  • the thickness of the metal strips used can be for example about 0.2 to 5 millimeters and the mesh size of the expanded metal from about 0.2 mm to a few centimeters.
  • the non-perforated portions 3 are put in the form of substantially semi-cylindrical surfaces 4, as shown in FIGS. 2A and 2B, for example by stamping, these substantially semi-cylindrical surfaces each receiving a preformed cylindrical tube 5, made integral with the substantially semi-cylindrical surface in contact with which it is by various means allowing the best possible thermal conduction between the metal parts in contact, for example by welding, by brazing or by bonding .
  • the non-perforated portions 3 of the strip 1 are put in the form of half-tubes 6, for example by stamping, and the opposite said half-tubes 6 of the complementary half-tubes 7, made separately, which are made integral with the half-tubes 6 by any means allowing the sealing between the inside and the outside of the tubes thus formed, for example by welding, by brazing or by gluing the edges of the half-tubes facing each other, or even by clamping with interposition of seals all along said edges facing each other.
  • FIGS. 4A and 4B combines opposite, for each row of tubes, two strips of expanded metal 8 and 9 comprising, like the strips 1 of FIG. 1A, perforated parts (respectively 10 and 11) and non-perforated parts (respectively 12 and 13), each of these strips 8 and 9 being formed for example by stamping, so as to have a plurality of half-tubes (14 and 15 respectively) with substantially parallel axes, the strip portions between two adjacent half-tubes corresponding to the perforated parts 10 and 11 being shaped, for example during drawing, so that at the level of these perforated portions, the two strips of metal deployed opposite are not in contact with one another, but separated by a distance denoted d, when the two half tubes 14 and 15 facing each other are in contact with each other, by their edges.
  • the two associated bands opposite are reduced to one another by any means allowing the sealing between the inside and the outside of each tube formed by the association of two half-tubes facing each other, for example by welding, by brazing or by bonding of the homologous parts in contact, or even by tightening with interposition of seals along said homologous parts.
  • the heat exchange structures according to the invention comprise a plurality of rows of tubes as described above. These various rows can be parallel to one another as shown diagrammatically in FIGS. 6A, 6B and 6C, the rows being able moreover to be arranged with respect to each other so that the tubes are arranged in staggered rows (fig. 6A) or aligned d 'one row to another (fig. 6B and 6C).
  • the strips of expanded metal which are at the base of the rows of tubes of the devices of the invention can be made up of various metals having varied properties, for example thermal conductivity, mechanical resistance , or corrosion resistance.
  • the fluid circulating in the tubes can more particularly be a liquid to be heated or cooled, the fluid circulating outside the tubes can more particularly be air to be cooled or heated, respectively.
  • each of the two fluids will be adapted to the types of exchange considered.
  • the fluid circulating in the tubes must be brought there and be evacuated by a distribution system and by an appropriate collection system.
  • the entire exchange structure can be placed in a sealed enclosure 16 provided with a supply duct 17 and a discharge duct 18 for the fluid which must circulate outside the tubes, as shown in FIG. 7.
  • the supply and discharge means of the fluid flowing in the tubes consists of conduits 19 and 20 connected respectively to the two faces 21 and 22 of the enclosure 16, perpendicular to the direction of the tubes 23, said faces 21 and 22 being pierced with holes 24 for communication with the tubes 23 which, in this way, pass through said enclosure 16 right through.
