Definitions

  • the invention relates to a cooling device comprising a liquid circuit which is guided through pipes and which is led through at least one cooling arrangement for cooling the liquid.
  • the devices are often connected to a common liquid circuit in which a liquid cooled by a cooling arrangement circulates.
  • the cooling arrangement can be designed, for example, as a sprinkler cooler or else comprise a refrigerator.
  • Conventional cooling arrangements even if they are compact, take up a comparatively large area of the production hall in which the devices or machines are installed.
  • US-A-1 840 573 shows a sprinkler cooler for the milk industry, in which the tubes through which the cooling liquid of a refrigerating machine flows are arranged one above the other in a meandering shape.
  • the milk to be cooled is passed over the pipes from the outside via sprinkling nozzles of a container arranged above the pipes.
  • an air conditioning system for a building in which a plurality of air conditioning units connected to a cooling liquid circuit are connected to a refrigeration machine which is in thermal contact with the cooling liquid circuit of the units via at least one heat exchanger.
  • the coolant circuit of the units is guided by pipes that form meandering convection heat exchangers in the air conditioning units.
  • the object of the invention is to show a simple way of how the cooling capacity of a cooling device with a liquid circuit guided through pipes can be improved with a small footprint.
  • the invention is based on the idea of extending pipes necessary for the liquid circuit anyway by means of a meandering design and at the same time using them for cooling.
  • the devices to be cooled are preferably connected in the area of connecting pieces of pipe sections running parallel to one another.
  • the liquid circuit can be passed directly through the devices to be cooled, as is also the case, for example, if the liquid of the cooling circuit is a product of a device of the food or beverage industry, or the devices to be cooled are passed through a second liquid circuit and one Heat exchanger connected to the liquid circuit of the meandering tube.
  • the meandering tube in particular including the heat exchangers used as connecting pieces, is stiffened to form a transportable unit.
  • this enables prefabrication and, on the other hand, the use of this structural unit as part of a prefabricated wall part of a building wall.
  • FIG. 1 shows a schematic representation of a cooling device according to the invention.
  • the drawing shows a cooling device for cooling several devices 1, such as machine tools or the like, which are connected to a common cooling circuit 5 via heat exchangers 3.
  • the cooling circuit 5 comprises a pipe system 9, which is circulated via a storage container 7 for cooling liquid and in which, circulated by a circulating pump 11, a cooling liquid, for example water, circulates.
  • a refrigeration machine 15 for cooling the liquid circulated in the pipe system 9 is coupled to the pipe system 9 via at least one, but preferably several, heat exchangers 13.
  • Cooling power forms part of the pipe system 9 a convection cooler 17, in which mutually parallel, horizontally arranged pipe sections 19 are arranged vertically one above the other essentially with a common vertical plane and at their ends by vertical connecting pieces 21 and the heat exchangers 3 and 13 connected to the pipe system 9 are connected to a meandering tube.
  • the pipe sections 19, 21 and the heat exchangers 3, 13 are connected to one another by frame elements, but in particular wall plates 23, to form a unit which is transportable per se.
  • the structural unit can be used as a prefabricated wall part of a building and can be connected to the rest of the installation of the pipe system 9 via connections 25, 27.
  • the devices 1 to be cooled can also be connected directly to the coolant circuit 5.
  • the horizontal pipe sections 19 are longer than the vertical connecting pieces.
  • the longer pipe sections can also be arranged vertically.
