Definitions

  • the invention relates to a container for cooling a cooling good using a coolant, in the interior of which the coolant stored in a coolant part is separated from a coolant part by a wall.
  • the cooling effect arises from the fact that, for example, the dry ice, which is predominantly used as a coolant, is evaporated while supplying heat from the environment or from the refrigerated goods container and the resulting cold gas is conducted into the interior of the refrigerated goods container.
  • the dry ice supply is sufficient, the losses through the walls of the refrigerated goods container can be at least partially compensated for.
  • At least one heat pipe is arranged in the refrigerated goods part of the container, from which the cold part projects into the coolant part and the warm part into the refrigerated goods part.
  • FIG. 1 schematically shows a refrigerated goods container K, which consists of a refrigerated goods part 1 with a refrigerated goods 2 stored therein and a coolant part 3 with a stored coolant 4, e.g. Dry ice, composed. Both the refrigerated goods part 1 and the coolant part 3 have insulation 5, 6.
  • a refrigerated goods container K which consists of a refrigerated goods part 1 with a refrigerated goods 2 stored therein and a coolant part 3 with a stored coolant 4, e.g. Dry ice, composed.
  • a stored coolant 4 e.g. Dry ice
  • the invention is based on the consideration that an improvement in the temperature conditions in the known refrigerated goods containers that work with a coolant supply can only be achieved if the heat flow between the refrigerated goods part 1 and the coolant part 3 is increased significantly, so that the heat losses that occur can be covered. This is achieved if at least one heat pipe 7 is used, in which the warm part projects into the refrigerated goods part 1 and the cold part into the coolant part 3. If there is a distance between the refrigerated goods part 1 and the coolant part 3, the cooling tube 7 is protected in this part by insulation 8. In practical use of the heat pipe 7 there is usually no distance between the two parts 1, 3.
  • Fig. 1 the heat flow is shown by arrows 9.
  • the heat pipe 7 is a device that causes a substantial increase in the heat flow 9. This results in a much more even temperature distribution, which means that the temperature required for meals and drinks in accordance with the existing regulations can be reliably maintained.
  • the heat pipe is an evacuated metal pipe that is closed on both sides, e.g. made of copper, the saturated vapor of a suitable cooling medium, e.g. contains high-purity water.
  • the condensed liquid is returned by capillary action on the inner wall of the pipe or by gravity. If the warm part of the heat pipe 7 heats up, liquid locally evaporates, which leads to an increase in pressure with a displacement of the steam to the other cold end of the heat pipe 7. The steam relaxes and condenses, releasing its latent heat. The liquid flows to the warm part by capillary action, whereupon the cycle repeats.
  • the colored refrigerated goods container shown in FIG. 2 has a refrigerated goods part 1 with insulation 5, a coolant part 3 with insulation 6, an intermediate wall 10 provided with insulation, and casters 11.
  • the refrigerated goods section 1 lies between two metal walls 12, e.g. made of aluminum, the actual storage space for the refrigerated goods, which is stored in portions 13, see FIG.
  • the number of heat pipes 7 depends on the temperature to be reached in the actual cooling room.
  • the heat pipe 7 In order to enable the required high heat flow, the heat pipe 7 must be in the cold part as well be provided with means to improve heat conduction in the warm part. In the container according to FIG. 2, this is achieved in that in the warm part, see FIG. 5, the heat pipe 7 is attached directly to the metal wall 12 and there is good contact. In this case, the metal wall 12 is a heat-conducting sheet, by means of which the heat transfer to the heat pipe 7 is improved.
  • the cold part of the heat pipe 7 is provided with ribs 16 which are arranged in a horizontal position around a coolant supply 17 lying in a shell.
  • FIG. 3 shows a further arrangement of the ribs 16 for the cold part of the heat pipe 7.
  • the coolant supply 17 lies on a base 18 which is in contact with the ribs 16 on its underside.
  • FIG. 4 shows that the bottom 18, on which the coolant 17 lies, is itself used as a heat conducting plate. There is thus the same arrangement as that provided in FIG. 5 for the warm part of the heat pipe 7. If the base 18 is designed as a sliding shelf, good contact with the cold part of the heat pipe or the heat pipes 7 must be ensured.
  • the floor 18 as well as the metal walls 12 expediently consist of a good heat-conducting material, e.g. Aluminum.
  • the refrigerated goods container described is characterized by great simplicity.
  • the use of heat pipes 7 makes it possible to achieve a better and more uniform temperature distribution in the refrigerated goods part 1 and thus completely cover the heat losses through the container walls.
  • the desired compensation can be achieved by locally increasing or reducing heat-conducting surfaces.
  • the heat can also be dissipated from those points which are further away from the coolant part 3.
  • the heat pipe 7 itself has a larger cooling surface, its cross section can deviate from the circular cross section and e.g. Rectangular cross-section.
  • the material of the tube can also be plastic.
  • the pipe must always be completely tight. The return of the liquid by capillary action is particularly necessary when the cold part of the heat pipe is below the warm part of the same; the inner wall of the heat pipe is then covered with a layer of capillary material, which ensures the transport of the liquid into the warm part of the heat pipe.
