Definitions

  • the present invention relates to a device for cooling the contents of a vessel, in particular a container for carbonating water for a vending machine, by means of a refrigerant which is passed through pipes arranged in a wrap shape on the outer wall of the vessel.
  • the pipelines for the refrigerant on the outer wall of the storage container.
  • e.g. B. should in a known manner (DE-A-30 16 941) a pipe for the refrigerant surrounding the storage vessel on the outer wall helically.
  • the contact between the pipeline and the container should be good heat conductor for the desired good heat exchange.
  • the present invention has for its object to provide, based on these findings, a device for cooling the contents of a vessel, which can be implemented relatively easily in terms of production technology, is suitable for cooling luxury foods and works with the highest possible efficiency. With a view to the lowest possible production outlay and the usability for luxury goods, the solution should be followed that the pipes for the storage vessel are arranged outside their walls.
  • a device corresponding to these requirements is characterized according to the invention in that the pipelines for the refrigerant in the region of the start of the winding and in the region of the end of the winding are placed under prestress on the wall of the vessel by means of clamping elements which are fastened to the vessel.
  • the pipeline is designed with a flattened cross section and a thermal paste is introduced between the pipeline and the vessel wall.
  • the pipeline in the area of the start of winding and in the area of the end of the winding is attached to the vessel via clamping elements and thereby permanently applied to the outer wall of the vessel under tensile stress, a high heat or Realized cold conductivity, so that the cooling device works with a relatively high efficiency.
  • This efficiency is further improved by the design of the pipeline with a flattened cross section and by the use of thermal paste between the pipeline and the vessel wall.
  • jaws are attached to them, via which the pipeline ends are clamped by elastic deformation.
  • the container itself should be made of metal and, with regard to the use for a luxury food, made of stainless steel.
  • the pipeline for the refrigerant is made of a good heat-conductive material. These materials usually also have a high temperature-dependent expansion compared to steel or stainless steel, for example. This property is particularly advantageous with regard to the device according to the present invention.
  • the pipeline therefore places itself particularly intensively on the outer wall of the storage vessel. Since the pipe for the coolant is fastened to the storage vessel at its winding ends, the tensile stress that occurs does not lead to loosening of the pipeline tension around the storage vessel. Outside of the cooling phases, the tension decreases again. There is therefore no fear of permanent elastic elongation of the pipeline.
  • the device according to the invention is also relatively simple and inexpensive to manufacture, preferably by means of a manufacturing process which is characterized in that the pipeline is clamped on the vessel wall in the region of the start of the winding, that the pipeline is pulled under tension on the circumference of the vessel with deformation of a Round cross-section is wound into an oval cross-section and that the pipe is then clamped in the region of its winding end under tension again on the vessel.
  • the vessel After clamping the start of the winding on the wall of the vessel, the vessel is rotated, the pipeline using tensile stress on the circumference the vessel is wound up.
  • the tube with a widespread commercial round cross-section is deformed into the desired oval cross-section with good contact with the vessel wall. After the end of the winding, the end of this pipeline is again clamped to the vessel wall and the pipeline is cut off after a continued connection piece.
  • Figures 1 and 2 show a storage container 1, as it is used, for example, in an automatic drinks machine for the preparation and storage of carbonated water.
  • a storage container 1 In order to support the one to carbonizing by mixing fresh water and CO 2 gas and for providing a cool drink, it is necessary or at least desirable to cool the storage container 1 and with it the C0 2 water supply.
  • pipes 2 are arranged helically on the circumference of the storage container 1, which are part of a cooling system, not shown.
  • the coolant is supplied from this cooling system via the inflow line 3 designed as a throttle section.
  • the return flow takes place via the drain line 4.
  • the storage container 1 is made of metal. At least its inner wall must be corrosion-resistant. It is expedient that the storage container 1 is made entirely of stainless steel.
  • the pipes 2 must have good thermal conductivity and are made of an appropriate metallic material. The efficiency for the cold transfer from the pipeline 2 to the storage container 1 essentially depends on the heat transfer resistance between these two elements.
  • This heat transfer is favorably influenced by the fact that the pipelines lie as intimately as possible on the reservoir 1. This is achieved in that the pipeline 2 rests against the storage container 1 by a tensile force acting on it under material-related elastic deformation. This tensile force is exerted on this pipeline 2 in the manufacturing process of the helical winding of the pipeline 2 on the container 1 and is permanently ensured on the start region 5 and the end region 7 of the pipeline 2 via clamping elements 6, 8, which are fastened to the reservoir container 1. During the clamping process, the area of the pipeline 2 which is gripped by the clamping elements 6, 8 is also deformed, so that the connection is both non-positive and positive. In order to increase the contact area between the pipeline 2 and the storage container 1, an oval cross section is selected for the pipeline 2. The remaining gaps between the pipeline 2 and the reservoir 1 are filled with thermal paste 12 to further improve the flow of cold.
  • the arrangement shown schematically in FIG. 4 is used to wrap the storage container 1 with the pipeline 2.
  • the starting area of the pipeline 2 is fastened on the storage container 1 by the clamping element 6.
  • the reservoir 1 is set in rotation by a drive 9, so that the pipeline 2 is drawn off from a storage drum 10 and is thereby wound onto the reservoir 1.
  • the required tension is generated by a clamping device 11. Due to the tension exerted on the pipeline 2 and the winding process, the originally round cross section of the pipeline 2 is also deformed to the desired oval cross section. After the winding process has ended, the end region of the pipeline 2 is also fastened to the storage container 1 with the clamping element 8. The separation from the pipeline fed from the storage drum 10 then takes place.
