  • the liquid drain opening 146 may include a gutter or trough 148 within the cooling space into which the condensed water from the cooling fins is forced by gravity.
  • This liquid collecting trough 148 can then be connected, as shown, to a liquid line 150, with the aid of which the condensed water is fed to the liquid receiving device 142.
  • a liquid line 150 In order to evaporate the condensed water collected in the liquid receiving device 146 as quickly as possible, the heat generated on the hot side 139 of the thermoelectric cooling element Heat with the help of the third fan means 140, in particular in the form of a rotary fan, directed in the direction or along the liquid absorption device 142.
  • FIG. 4 shows a schematic plan view of an embodiment of the second cooling fin module 200 according to the invention, as in the cooling device according to Figures 2 and 3 can be used.
  • the cooling rib module 200 has cooling ribs 202 running obliquely with respect to the horizontal.
  • the cooling ribs 202 have an inclination angle of approximately 45 °.
  • the cooling rib module 200 has two sets of cooling ribs, which are arranged mirror-symmetrically to one another and thus essentially reproduce a roof shape.
  • the respective obliquely converging cooling fins are connected to each other at their respective meeting points. A passage of liquid into the separated by the cooling fin adjacent remplisstechniksablaufrinne 204 is therefore not possible.
  • the cooling fins, as well as the upper edge and the base surface 216 of the cooling fin module are preferably made of metal.
  • the condensate dripping down through the orifices 210 is collected in the liquid receiver 148 and discharged via conduit 150 from the cold room to a liquid receiver (not shown).
  • FIG. 5 shows a schematic plan view of an embodiment of the first cooling fin module 300 according to the invention.
  • the cooling ribs 302 extend substantially parallel to each other. Between the cooling fins 302 are the remplisstechniksablaufrinnen 304 before.
  • the liquid drainage channels 304 are not flat in cross-section, but designed trough-shaped. Both the drip end 306 and the opposite inlet end 308 of the liquid drains 304 are open. This serves the purpose of permitting circulating air introduced via an inlet opening into the cooling and first circulating air region to freely enter the liquid drain channels 304 via the inlet end 308 and to escape via the dripping end. As a result, the removal of condensed liquid is forced again.
  • a further promotion of the removal of condensed liquid is caused by the, in particular U-shaped or V-shaped, notches 310 which are present at the drip ends 306.
  • FIG. 6 a cross-sectional view of an embodiment of the first cooling fin module 300 according to the invention.
  • the cooling fin combs 314 are in this case oriented substantially horizontally.
  • a metallic product support plate can be placed.
  • the liquid discharge channels 304 have an inclined course 312 from the inlet end 308 in the direction of the drip end 306.
