Definitions

  • the present invention relates to improvements made to temperature exchangers, that is to say devices capable of supplying or absorbing heat. It is more particularly, although not exclusively, relating to a refrigerator implementing such a temperature exchanger.
  • a pipe for circulating hot or cold fluid or other thermal source is generally used with which an exchange wall is associated in thermal contact.
  • This wall must have the largest possible developed area so as to improve the performance of the assembly.
  • Such walls are commercially available, for example, in the form of extruded aluminum profiles. It is easily understood that the assembly of such walls with a pipe is not easy, since it is necessary to provide shells or the like to make an intimate connection between the wall and this pipe. If the latter does not have a very regular shape, there is also significant heat loss.
  • the improvements which are the subject of the present invention aim to allow the production of a simpler and less expensive wall than those currently available.
  • the wall comprises at least one plate provided with slots regularly spaced from each other, and fins interposed between said slots and raised from the general plane of the plate, as well as a sheet arranged in the same way as this plate, the latter and said sheet being assembled one inside the other in such a way that the fins of the sheet are engaged in the slots of the plate, between the fins of the latter, and that the solid parts of the sheet close up the slots in the plate.
  • the wall can be advantageously produced exchange by means of thin sheets of light alloy, for example aluminum. It is therefore possible to obtain the two elements of the wall in a single cutting-forming operation, the fins being constituted by the material cut to obtain the slots. Such an achievement is inexpensive.
  • the establishment of the exchange wall is facilitated by the flexibility of the light material. This flexibility also makes it possible to obtain excellent thermal contact between the fluid circulation pipe and the heat exchange wall.
  • An exchanger according to the invention can advantageously constitute the evaporator of a refrigerator, and more particularly the refrigerated compartment disposed inside said refrigerator.
  • FIG. 1 There is shown in fig. 1 the main elements of a heat exchange wall according to the invention which have been assigned the general reference 1 and which is intended to be associated with a pipe 2 in which circulates a fluid brought to a determined temperature so that the assembly could constitute a temperature exchanger.
  • the heat exchange wall 1 comprises a tunnel 3 formed by two vertical plates 4 joined by a web 5 located at their upper edges.
  • Each plate 4 is cut so as to present vertical openings or slots 4a which each allow a fin 4b to be raised perpendicular to the general plane of the plate, the width of each fin being the same as that of the corresponding slot. Note that each slot 4a has an oblique lower edge.
  • each plate 4 is folded down to form a rim 4c intended to come to cooperate with the underside of each of the branches of the pipe 2 which affects the shape of a loop.
  • the tunnel 3 is advantageously made from a single blank of a thin sheet of light alloy.
  • Each plate 4 cooperates with a sheet 6 of thin sheet of light alloy cut in the same way as the corresponding plate, in other words each of the sheets is provided with vertical openings or slots 6a allowing the constitution of fins 6b coming from the one of the vertical edges of the slot and oriented perpendicular to the general plane of the sheet.
  • the distance separating two neighboring slots 6a is equal to the width of the slots.
  • the fins 6b of the sheet 6 can be engaged in the slots 4a of the plate 4 so that they come to be arranged parallel to the fins 4b. Care is taken to move the sheet 6 longitudinally relative to the corresponding plate 4 (Fig. 3) so that the strips 6c which separate the slots 6a are placed in front of the slots 4a in order to close them. Symmetrically, the strips 4c which separate the slots 4a block the slots 6a. A continuous composite partition is thus obtained from which a series of fins .4b, 6b extend laterally.
  • each sheet 6 is provided with a fallen edge 6d which comes to bear against the above the corresponding branch of the pipe 2. Due to the oblique shape of the lower edge of the fins 4b, the part of the slot which served for its constitution has a notch not covered by the sheet 6.
  • the two branches of the loop 2a are connected by a floor 8 produced by means of two symmetrical elements 8 ', 8 "made from a thin sheet of aluminum.
  • Each element 8', 8" has a fallen edge 8 ' a, 8 “a and a rounded gutter 8'b, 8” b.
  • the latter surrounds the corresponding branch of the loop 2a while the fallen edges 8'a, 8 "a which are oriented vertically, are in abutment against one another.
  • a shoemaker 13 closes the lower part of the tunnel 3 and the front of the assembly shown in FIG. 4.
  • the front of this shoemaker has a door 13a giving access either to a refrigerated compartment constituted by a heat exchange wall such as that shown in fig. 2, or to chamber 12 by means of an opening 13b.
  • the lower part 13c of the shoemaker 13 constitutes a gutter intended to collect the defrosting water.
  • the two loops of the pipe 2 are not flat since they are part of the same pipe whose entry into the refrigerator and the outlet towards the general circuit are close to each other. Thanks to the flexibility of the lower edges 4c and ' 6d of the plate and of the sheet corresponding to each loop branch, the whole of the wall 1 can maintain a horizontal orientation.
  • the tray forming the lower part of the compartment 12 is executed in two pieces, said tray does not have to exactly affect the shape of the loop 2a of the pipe 2, these are its two parts 8 ′, 8 "which are offset relative to each other.
