ARRANGEMENT IN CONNECTION WITH COOLING ELEMENT INCLUDING CONDENSATE GUTTERS
Refrigerator device provided for connection to a cooling unit, and for being mounted with an open, exposed lower side, particularly for being used at a cooling device for releasing cooled air to an underlying entity of cooled goods. A number of generally parallel cooling lamellas (15) being arranged in an assembly to restrict slots for passing air to be cooled. The cooling tubes being arranged in groups 18. Under each such group a longitudinal collecting chute (19) is provided to collect condensed water from the cooling tubes and release it at one end (13). At the end of the collecting chutes (19) being supplied with condensed water, a crossing chute (16) is arranged, providing a collected release of condensed water (at 17).

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.
BACKGROUNDRefrigerator 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.
A satisfactory solution of this problem has not been available.
OBJECTThe 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 INVENTIONThe 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.
In claims 2-6 particularly advantageous features of the invention are stated. Further details of the invention will appear from the following specification.
The invention will be further described with reference to the drawings, wherein
In
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.

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:
-
- An upper lug 25 and a lower lug 26 facing the lower side of the sheet,
- A lug 27 facing the bottom of the V-chute 23, and
- A lug 28 pressing against the upper side of the sheet at the upper edge.
Thus the water condensed on the cooling tubes will drip on the collecting chute 19 and be collected there together with water condensed on the upper side of the collecting chutes. Water condensed on the lower side of the collecting chutes 19 will trickle to the lower edge of the chute 23 and drip to a V-chute 29 arranged under the collecting chute 19, parallel thereto. The V-chute 29 is passed through V-slots 30 in the end elements 12 and 13, with corresponding lugs 31, 32, 33 as the upper collecting chute.
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.
This will avoid drops from the refrigerator device according to the invention. This is particularly advantageous at cooling elements being open on the lower side, without the possibility to deposit condensed water.
