Definitions

  • the present invention refers to a condenser of the tube-plate type to be used in the refrigeration system of appliances, such as refrigerators and freezers presenting an internally refrigerated cabinet with external walls that are at least partially defined in a metallic plate.
  • the tube 10 that defines the metallic condensation coil is simply seated against the inner face of a respective external wall 20 of the cabinet G of the refrigeration appliance, said tube 10 being retained against the external wall 20 by a tape 30 , made of aluminum or any other thermally conductive material, which is medianly applied to the tube 10 and has end portions that are glued or otherwise affixed to said external wall 20 .
  • the tube 10 and the tape 30 are afterwards covered by the thermal insulation of the cabinet G, which insulation is generally defined by a filler 50 of polyurethane contained between the external wall 20 and an internal wall 40 of the cabinet G.
  • the present invention proposes a condenser comprising at least one condensation coil formed by a plurality of tube extensions for conducting the refrigerant gas, which are seated and retained in respective grooves formed by bending the metallic plate of a respective external wall of the cabinet.
  • Each groove is configured and dimensioned to tightly “embrace” preferably more than half the perimeter of the outer face of the respective tube extension, so as to maximize the contact area between the tube extensions and the metallic plate that defines the respective external wall of the cabinet.
  • FIG. 1 is a cross-sectional view of a tube extension of a condensation coil affixed against the inner face of an external wall of a cabinet according to the prior art construction;
  • FIG. 2 is a similar view to that of FIG. 1 , but illustrating only an enlarged small portion of a corner of the cabinet;
  • FIG. 3 is a similar view to that of the previous figure, but illustrating a preferred form of carrying out the present invention.
  • FIG. 4 is a somewhat schematic perspective view of a condenser of the tube-plate type comprising a condensation coil, which is mounted, according to the present invention, to a rear external wall of an internally refrigerated cabinet; and an additional condensation coil that is conventionally adapted to the inner face of the top external wall of the cabinet.
  • the present condenser of the tube-plate type is applied to the refrigeration system of different refrigeration appliances, such as refrigerators and freezers presenting a cabinet G to be internally refrigerated and which has external walls 20 , generally in a metallic plate, and internal walls 40 usually defined in a single piece of plastic material and denominated inner box. Between the internal walls 40 and the external walls 20 a filler 50 of polyurethane foam is inserted to provide the required thermal insulation to the cabinet G.
  • the invention proposes a construction, according to which the condenser comprises at least one condensation coil S, which is formed by a plurality of tube extensions 10 , for conducting the refrigerant gas, which are arranged in series relative to each other and to the refrigeration system to which the condenser is applied, each tube extension 10 being seated and retained inside a respective groove 21 , formed by bending the metallic plate of a respective external wall 20 of the cabinet G.
  • the groves 21 are generally rectilinear and mutually coplanar. However, it should be understood that other arrangements could be provided in which the grooves 21 are not rectilinear and coplanar.
  • the grooves 21 are opened to the outside of the respective external wall 20 of the cabinet G.
  • the external wall 20 used can be the one that defines the rear closing part of the cabinet G, considering that this external wall 20 is generally made of a steel plate as a separate piece from the single metal sheet that defines the lateral and upper external walls of a parallelepipedic cabinet G. It should be understood that the grooves 21 can open to the interior of the respective external wall 20 , which would present ribs on the outer face thereof, resulting from the bottom of the grooves 21 projecting outwardly from the plane of said external wall 20 .
  • each tube extension 10 presents a cross section that is configured and dimensioned to tightly “embrace” the tube extension 10 , by preferably contacting more than half the external perimeter of the latter.
  • the tube extensions 10 of the condensation coil S are lodged inside the respective grooves 21 of an external wall 20 , whose metallic plate is previously stamped. Subsequently, the metallic plate is submitted to a localized pressing, in order to partially close the grooves 21 around the tube extensions 10 , embracing the latter and assuring a larger contact area and the retention of the tube extensions 10 inside the grooves 21 , since the opening 21 a of the latter now presents a width that is smaller than the largest transversal dimension of the tube extension 10 , taken according to a direction parallel to the respective external wall 20 .
  • the tube extensions 10 can be seated inside the grooves 21 and affixed therein by an additional common fixation element, which is coupled to the external wall and acts against the exposed surface portion of the tube extensions 10 .
  • the tube extensions 10 generally present a circular cross section, making the grooves 21 present the same cross section shape, in order to operate as a cradle, in which the respective tube extensions 10 will be tightly seated.
  • the grooves 21 present a depth that is substantially equal to the largest transversal dimension of the tube extension 10 , taken at a direction that is orthogonal to the respective external wall 20 .
  • the external surface of the tube extension 10 is generally arranged in a tangential way in relation to the plane of the external wall 20 , allowing the formation of a condenser that is entirely contained in the external contour of the cabinet and with the constructive and assembly advantages mentioned above.
  • the provision of one or more additional condensation coils S 1 , S 2 may be required, arranged in series with the condensation coil S and associated with the top and bottom external walls 20 of the cabinet G.
  • the tube extensions 10 can be seated and affixed against the flat inner face of the external walls 20 that define the top and bottom of the cabinet G, according to the prior art construction, as illustrated in FIG. 4 , in which the additional coil S 2 seated against the inner face of the bottom external wall 20 is represented in dashed lines.
