Definitions

  • the invention relates to a refrigerator device as stated in the introductory part of claim 1 , provided for being suspended with an open, exposed lower side.
  • Refrigerator devices provided for being mounted, e.g. by being suspended, with open and exposed lower side, belong to prior art. Such refrigerator devices are provided for special cooling cabinets or for being mounted freely over a merchandise. In such refrigerator devices water condensed on the cooling lamellas is liable to drip and deposit water on the merchandise and equipment which should be kept dry or which is requiring supply of water as a mist.
  • the main object of the invention is to provide a refrigerator device staying dry in the meaning of not depositing moisture uncontrolled as drops to the underlying area.
  • a drop catcher is desirable, wherein increased efficiency does not increase the deposit of drops, particularly in connection with refrigerator devices being suspended over a merchandise to be cooled.
  • the Invention is stated in claim 1. These features allow a substantial increase in the thermal transfer and reduction of the temperature of the air flowing from such a refrigerator device.
  • Figure 1 shows a plane view from above, of an embodiment of the invention, with a refrigerator device with lamellas on cooling pipes,
  • Figure 2 shows an end view of the refrigerator device of Figure 1
  • Figure 3 shows a side view of a lamella for the refrigerator device of Figure 1
  • Figure 4 shows an enlarged part of Figure 3.
  • FIG. 1 a refrigerator device 11 which is assembled between two end elements 12, 13 is shown. Between the end elements 12, 13, a series of cooling tubes 14 are connected for the conduct of a cooling medium.
  • the cooling tubes 14 are carrying a series of cooling fins or lamellas 15.
  • the cooling lamellas 15 are extending over the total height of the cooling element 11 and are connected to the cooling tubes 14. The distance between the cooling lamellas may be 9 millimetre.
  • the refrigerator device 11 of the example is shown with vertical extension of the slits, with gravitational air transfer.
  • the cooling element according to the invention can also be used at cooling devices provided with a fan. This will allow a freer positioning.
  • the refrigerator device 11 according to the invention can be utilized for various cooling purposes, technical as well as for residential use. E.g. it is suitable for cooling elements to be arranged freely over the goods to be cooled.
  • FIG 2 the arrangement of an inclined collection chute 16 for condensed water, under the refrigerator device 11 , at one end thereof, under the end of the end element 13, is shown.
  • the collection chute 16 ends in a chamber 17 with a pump with level control, for emptying of condensed water.
  • FIG 3 a side view of a cooling lamella 15 is shown, with an enlarged part shown in Figure 4.
  • the cooling tubes 14 are arranged in vertical rows 18, with four cooling tubes 14 in each row. Adjoining such a row 18 a collecting chute 19 is arranged.
  • the collecting chute 19 has a plane, longitudinal main part 20 being inclined with the lower part under the cooling tubes 14, an upper narrow perpendicular flange 21 , pointing downward, and a lower flange 22, also being perpendicular to the main part, providing a V-chute 23 to remove condensed water.
  • the collecting chutes 19 are passes through S-slots 24 in the lamellas 15 and in the end elements 12, 13, which are adapted to the section of the collecting chutes.
  • Each slot 24 is wider than the thickness of the sheet and is provided with knots facing the sheets to make contact:
  • This arrangement will bring condensed water from the refrigerator device 11 to be collected in the chutes 23 and 29, and from there to be collected at an end of the refrigerator device 11.
