Definitions

  • the invention relates to a temperature exchanger device comprising a means for circulating a fluid and at least one heat exchange wall in thermal contact with said means. It is more particularly, although not exclusively, relating to a refrigerator implementing such a heat exchanger.
  • the heat exchange wall of this device is not continuous, due to the interstices formed on each side of a solid part in a corresponding slot; this is unfavorable if good thermal efficiency is sought, particularly a "freezer" for a refrigerator compared to the rest of the refrigerator.
  • the implementation of such an exchanger requires the production and use of two completely separate tools for cutting and forming the fins of the two plates respectively. This obviously increases the cost price of the exchanger made from the two plates in question.
  • the invention therefore proposes to obtain a temperature exchanger device, particularly suitable for the production of a "freezer” for a refrigerator, reconciling good thermal efficiency and great simplicity of implementation.
  • the cutting and forming of the fins can be obtained for each plate with the same tool which reduces the investment in manufacturing means.
  • the cutting and forming considered can be obtained in a single press stroke which reduces the manufacturing time while the assembly of the two plates, being carried out by simple juxtaposition, contributes to the reduction of the setting time. artwork.
  • each plate being directly applied against the means for circulating the fluid, there is an excellent transmission of calories between said means and the device.
  • 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 device comprises a tunnel 3 formed of two vertical plates 4 joined by a web 5 located at their upper edges.
  • Each plate 4 is cut so as to have 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.
  • each slot 4a has an inferior edge oblique laughter.
  • the lower part of each plate 4 is folded down to form an edge 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 another plate 6 of thin sheet of light alloy cut in the same way as the corresponding plate, in other words each of the plates 6 is provided with vertical openings or slots 6a allowing the constitution of fins 6b from one of the vertical edges of the slot and oriented perpendicular to the general plane of the plate considered.
  • the distance separating two neighboring slots 6a is equal to the width of the slots.
  • the fins 6b of the plate 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 plate 6 longitudinally relative to the corresponding plate 4 (fig. 3) so that the strips 6c which separate the slots 6a come to be placed in front of the slots 4a in order to close them. Symmetrically, the strips 4d 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 plate 6 is provided with a fallen edge 6d which comes to bear against the top of 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 plate 6.
  • the two branches of the loop 2a are connected by a floor 8 produced by the hub 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.
  • the space between the tunnel 3 and the box 9 is filled with an insulating material 10 such as expanded polystyrene, while a plate 11 of the same material located between the two loops of the pipe 2 isolates a chamber 12, constituted by the floor 8 and the box 9.
  • the chamber 12 is thus cooler than the enclosure cooled by the first loop of the pipe 2 and the tunnel 3 since the loop 2a thereof is located most upstream. It is in this room that frozen food is generally placed.
  • a housing 13 closes the lower part of the tunnel 3 and the front of the assembly shown in fig. 4.
  • the front of this box 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 housing 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 plates 4 and 6 corresponding to each loop branch, the whole of the wall 1 can maintain a horizontal orientation.
  • the plate forming the lower part of the chamber 12 is made in two parts, said plate 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 from each other.
