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 base area of the manufacturing hall in which the devices or machines are installed.
  • This object is achieved according to the invention in that at least a partial length of the tubes of the liquid circuit runs in a meandering manner to form the cooling arrangement in an essentially vertical plane.
  • the invention is based on the idea of extending the pipes required 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 the meandering part of the pipe, preferably 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 else 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 liquid circuit guided through the meandering tube can be led directly through a refrigerator; however, the refrigerator can also be connected via a heat exchanger and a third liquid circuit.
  • 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.
  • the meandering tube can be accommodated in an essentially disk-shaped, flat container through which a liquid cooling circuit in heat exchange contact with the tubes is guided.
  • This variant allows, in particular in applications in the food industry, a perfect separation of the liquid passed through the meandering tube, for example a drink, and the liquid supplying the cold from the cooling circuit passed through the container.
  • sprinkler coolers with a small footprint can be constructed in the above manner.
  • FIG. 1 shows a schematic illustration of a cooling device according to the invention
  • FIG. 2 shows a schematic illustration of a cooling device according to the invention constructed as a spray cooler
  • the cooling circuit 1 shows a cooling device for cooling a plurality of devices 1, such as, for example, 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.
  • a partial length of the pipe system 9 forms a convection cooler 17, in which 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 ones
  • Connecting pieces 21 and the heat exchangers 3 and 13 connected to the pipe system 9 are connected to form a meandering pipe.
  • the pipe sections 19, 21 and the heat exchangers 3, 13 are connected to one another by frame elements, in particular, however, wall plates 23, to form a transportable unit.
  • 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 cooling liquid circuit 5. If the cooling effect of the meandering tube is already sufficient, the refrigeration machine 15 can be omitted if necessary.
  • the sprinkler cooler 31 comprises a plate-shaped or disk-shaped housing 37, which is arranged essentially vertically with its disk plane and in which a meandering tube 39 is arranged.
  • the meandering tube 39 comprises vertically superposed, horizontally extending tube sections 41 which are connected to one another at their ends by vertical connecting pieces 43.
  • Above the meandering tube 39 is a with a sprinkler pipe 47 provided with a plurality of nozzles 45.
  • the sprinkler pipe 47 sprinkles the meandering pipe 39 with food-safe liquid, such as water, which is drawn off from the underside of the container 37 by a circulating pump 49 and is supplied to the sprinkler pipe 47 in the circuit.
  • a refrigeration machine not shown, is coupled to this circuit via a heat exchanger 51.
  • the separation of the coolant circuit of the refrigeration machine and the pipe system 33 prevents the refrigerant circuit of the refrigeration machine from getting into the food circuit in the event of a leak in the refrigerant circuit.
  • the sprinkler cooler 31 forms a unit which is transportable in itself and which requires only a comparatively small footprint for installation.
  • the horizontal pipe sections 19 and 41 are longer than the vertical connecting pieces.
  • the longer pipe sections can also be arranged vertically.

Abstract

Afin de renforcer l'effet de refroidissement d'une machine frigorifique (15), une partie du système de canalisations (9) qui relie les appareils à refroidir (1) se présente sous forme d'un tube sinueux (19, 21) dont les sections (19) sont superposées sur un plan commun et mutuellement reliées de manière à former un module transportable individuellement. Le tube sineux forme un refroidisseur par convection ayant une aire relativement réduite qui renforce l'effet de refroidissement de la machine frigorifique (15).
