Definitions

  • the present invention relates to a tube / plate liquefier for a cooling circuit of a refrigerator and / or freezer, with a preferably meandering curved tube in which the cooling circuit medium is liquefied, and a support panel made of sheet metal, to which the tube is attached.
  • Such a tube / plate liquefier for refrigerators and / or freezers is for example from the DE 20 2004 017 652 U1 known.
  • Such meshwandvertheer consist of a steel sheet on which the meandering curved steel pipe is placed and fixed, wherein regularly both the steel sheet and the steel pipe are painted. Since in such condensers, the heat dissipation is limited, the meandering curved tube must have a correspondingly large length and the heat dissipation serving to the environment support panel made of sheet metal a correspondingly large area so that the vaporized refrigerant in the evaporator of the refrigeration circuit sufficiently cooled when flowing through the pipe and so that it is liquefied again.
  • DE 20 2004 017 652 U1 proposes to improve the heat dissipation, the meandering reciprocating condenser tube with a certain bending radius provided and thus give the straight lines a predetermined distance, as this is to achieve a more uniform heat radiation over the surface of the carrier panel. Nevertheless, the heat dissipation remains limited and thus the necessary Auspaneel Structure and tube length considerable.
  • the present invention is based on the object to provide an improved condenser of the type mentioned, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner.
  • a further improved heat dissipation and / or a smaller size of the condenser should be achieved.
  • the present invention is based on the consideration that the heat dissipation of the evaporator can be effectively improved on the one hand by increasing the thermal conductivity of the carrier panel and on the other hand by increasing the heat transfer from the condenser to the plate of the carrier panel, both of which are particularly by a special Material pairing between the material of the carrier panel and the material of the tube can be achieved.
  • the support panel consists of an aluminum sheet, while the pipe is a steel pipe or an aluminum pipe.
  • the pipe is a steel pipe or an aluminum pipe.
  • the aluminum sheet has a significantly better thermal conductivity compared to the previously customary steel sheets.
  • the tube can be positively and / or non-positively connected to the carrier panel.
  • the carrier panel may according to an advantageous embodiment of the invention have curved tube receiving channels, in which the tube is inserted, so that the aluminum sheet encloses the tube surface.
  • the tube receiving channels surround the tube in cross section by more than 180 °, so that the heat transfer surface and thus the heat dissipation is particularly large. In addition, this ensures a firm connection between sheet and tube.
  • a press or clamping fit is provided between the tube receiving channels and the tube.
  • the tube can basically be added differently in the tube receiving channels.
  • the tube may be rolled into the aluminum sheet in the region of the tube receiving channels.
  • the support panel can in principle be made of a single sheet metal sheet, but it is alternatively also possible to assemble the support panel from several pieces of sheet metal.
  • the support panel may consist in particular of a plurality of overlapping metal strips, if the tube is not rolled into the aluminum sheet, but is taken up between overlapping metal strips of the carrier panel. As a result, a complete enclosure of the tube of the material of the carrier panel can be achieved.
  • a steel tube is used as condenser tube, this can basically be a bare steel tube without surface coating or treatment. Alternatively, a particularly favorable combination of materials results even when galvanized Steel tube is used. The same applies to tin-plated steel pipe. This also makes it possible to achieve a particularly favorable heat transfer.
  • the aluminum sheet support panel and / or the condenser tube may be left unpainted according to an embodiment of the invention.
  • a painting can be provided as an alternative.
  • the condenser 1 shown in FIG. 1 comprises a substantially plate-shaped carrier panel 2 and a condenser tube 3 connected thereto, which is guided back and forth in meandering fashion and has an inlet 4 and an outlet 5.
  • the refrigerant releases the heat absorbed via the condenser tube 3 to the carrier panel 2 and via this to the environment, so that the evaporator medium or the refrigerant is cooled and re-liquefied until it flows through the outlet 5 in the subsequent functional unit of the refrigeration cycle is initiated again.
  • the carrier panel 2 is made of a sheet of aluminum or an aluminum alloy.
  • the tube 3 may also consist of aluminum or an aluminum alloy according to an embodiment of the invention.
  • a condenser tube 3 a steel tube may be used, which may be galvanized according to an embodiment of the invention or tinned according to an alternative embodiment of the invention.
  • the condenser tube 3 is not simply placed on the carrier panel 2 of the condenser. Rather, the carrier panel 2 has substantially rectilinearly extending tube receiving channels 6, in which the condenser tube 3 is inserted and in which the condenser tube 3 is wrapped by the sheet metal of the carrier panel 2, so that on the one hand, a large contact area between the carrier panel 2 and condenser tube 3 results on the other hand, the condenser tube 3 is held positively and / or non-positively in the tube receiving channels 6.
  • the tube 3 is rolled into the sheet metal of the carrier panel 2.
  • the sheet metal of the carrier panel 2 is folded or curved in the shape of a channel, so that the sheet of the carrier panel 2 surrounds the tube 3 in a range of approximately 270 °.
  • the carrier panel 2 is made essentially of a one-piece aluminum sheet.
  • the carrier panel 2 is produced from a plurality of overlapping metal strips, wherein a tube receiving channel 6 is formed between each two overlapping metal strips 7 and 8 and the corresponding condenser tube piece is completely enclosed by the plate of the carrier panel 2 (see FIG. ,
