Definitions

  • the invention relates to a cooling device, in particular for an electrical cabinet, having a refrigeration circuit that comprises an evaporator, a condenser, and a compressor, the condensed water that occurs being evaporated in a condensate evaporator having a condensed water receiving space.
  • Cooling devices of this kind are used, for example, for climate control of electrical cabinets in which a number of electronic components, which discharge considerable dissipated power in the form of heat, are accommodated.
  • the condensed water occurring at the evaporator drips off and is caught in a condensate collection container arranged therebeneath. It is known to convey the condensed water, using a pump device, out of the condensate collection container to an electrically heated condensate evaporator in which the condensate is evaporated and discharged as water vapor to the environment.
  • the condensate evaporator used for this is intended to be of the simplest possible construction.
  • the receiving space is arranged in thermal contact with the compressor; and in order to generate water vapor, the condensate is heated by the waste heat of the compressor.
  • the waste heat of the compressor is used to heat and to evaporate the condensed water present in the receiving space.
  • additional energy for example for an electrically operated heating system, is omitted.
  • the waste heat that is in any case produced by the compressor of the cooling unit is used for evaporation.
  • the condensate evaporator according to the present invention is thus, overall, economical in terms of manufacture and operation.
  • the receiving space can abut against the enveloping surface of the compressor and can at least partly fit around it. This on the one hand ensures that good thermal contact exists between the compressor and the receiving space. On the other hand, a particularly compact configuration is achieved.
  • the receiving space can be embodied as a collection trough.
  • the collection trough can comprise a substantially rectangular cross section open toward the top, and a thin inner wall abutting against the enveloping surface of the compressor, a bottom, and an outer wall.
  • a configuration of this kind can be manufactured very easily, for example, as an injection-molded plastic part. The thinner the configuration of the inner wall abutting against the enveloping surface of the compressor, the better the heat transfer from the compressor to the condensed water that is located in the receiving space and is to be evaporated.
  • a thermally conductive paste can be introduced between the inner wall of the receiving space and the enveloping surface of the compressor.
  • the condensate occurring at the evaporator of the cooling unit can be introduced via an inflow hose into the receiving space of the condensate evaporator.
  • the condensate collected at the evaporator in a suitable vessel can flow by gravity, i.e. without the use of an electrically operated pump, into the receiving space of the condensate evaporator.
  • the inflow hose can be held by a holding element in a manner oriented substantially perpendicular to the bottom of the receiving space.
  • the holding element can be, in particular, a cross-type fitting or a suitable rib arrangement shaped onto the bottom of the receiving space.
  • a through hole, onto which an overflow tube projecting into the receiving space is shaped can be embodied on the bottom of the receiving space.
  • the height of the overflow tube above the bottom of the receiving space is less than the height of the inner or outer wall of the receiving space.
  • a tubular fitting onto which a suitable runoff hose can be attached can be shaped onto the through hole, on the lower side of the bottom facing away from the receiving space.
  • the receiving space can comprise at least one region having an enlarged cross section, in which region the holding element of the inflow hose, and/or the overflow tube, are shaped on.
  • the receiving space can comprise at least one region having a constricted cross section.
  • the receiving space can at least partly fit around the enveloping surface of the compressor in approximately C-shaped fashion, the free ends of the receiving space being closed off by terminating walls.
  • the free ends of the receiving space can be secured with respect to the enveloping surface of the compressor by means of a clamping element.
  • the clamping element which in particular can be a spring clip, can engage onto extensions that are shaped onto the free ends of the receiving space.
  • the invention further describes a cooling device, in particular for an electrical cabinet, having a refrigeration circuit that comprises an evaporator, a condenser, and a compressor, the condensed water being introduced into the condensate evaporator according to the present invention that is arranged in thermal contact with the compressor.

  • Receiving space 12 furthermore comprises a region 34 having a constricted cross section. This constricted cross section serves for flexible bending of the C-shaped receiving space 12 for installation onto a compressor (not shown in FIG. 2 ).
  • the C-shaped receiving space 12 forms two free ends 36 a and 36 b .
  • Free end 36 a is closed off by a terminating wall 38 a
  • free end 36 b by a terminating wall 38 b.
  • a clamping element 40 Shaped onto free ends 36 a and 36 b of receiving space 12 , and prolonging terminating walls 38 a and 38 b , are respective extensions 42 a and 42 b onto which a clamping element 40 , embodied as a spring clip, engages.
  • the clip-shaped clamping element 40 is shaped from a resilient metal sheet and has two ends 44 a and 44 b that are bent into an S- or Z-shape. End 44 a of clamping element 40 engages behind extension 42 a at free end 36 a of receiving space 12 , whereas end 44 b of clamping element 40 engages behind extension 42 b at free end 36 b of receiving space 12 .

  • Receiving space 12 of the condensate evaporator is arranged in thermal contact with compressor 10 , receiving space 12 being abutted against enveloping surface 14 of the compressor.
  • Receiving space 12 embodied as a collection trough, abuts with its thin inner wall 16 directly against enveloping surface 14 of compressor 10 .
  • a thermally conductive paste (not shown) can additionally be introduced between enveloping surface 14 of compressor 10 and inner wall 16 of receiving space 12 .
  • Receiving space 12 fits around enveloping surface 14 of compressor 10 in approximately C-shaped fashion, free ends 36 a and 36 b of receiving space 12 being secured by means of clamping element 40 with respect to enveloping surface 14 of the compressor.
