Definitions

• the present invention relates to a refrigerator and/or freezer with an interior to be cooled for accommodating the goods to be refrigerated and/or frozen and with a magnetic cooler.
• the magnetic cooler can be composed of a magnetocaloric material which is heated upon magnetization and is cooled upon demagnetization.
• the heat transfer medium flows through the magnetized and hence heated part of the magnetic cooler, it is heated.
• the heat transfer medium then traverses a warm heat exchanger, which for instance is located on the outside of the appliance and which is cooled by a suitable cooling medium.
• the heat transfer medium traversing the demagnetized and hence cooled region of the magnetic cooler is cooled.
• the heat transfer medium cooled in this way then reaches the so-called cold heat exchanger, which is arranged such that it cools the interior of the appliance.
• particles of a magnetocaloric material are incorporated in the heat transfer medium and the heat transfer medium then is heated due to the fact that the magnetocaloric material is magnetized and thus heated. Cooling is achieved in that the magnetocaloric material is demagnetized, which results in a reduction in temperature of the magnetocaloric material and also of the heat transfer medium.
• the invention comprises any kind of configuration and operating principle of a magnetic cooler.
• the commonly used appliances which employ a refrigerant compressor positioned outside the appliance, furthermore are known from the prior art.
• the same is arranged in the lower region on the back of the appliance.
• the magnetic cooler is at least partly arranged in the interior of the appliance.
• the invention furthermore relates to a refrigerator and/or freezer with an interior to be cooled for accommodating the goods to be refrigerated and/or frozen, with a magnetic cooler and with a thermal insulation, which is arranged between the interior of the appliance and the surroundings of the appliance, wherein the magnetic cooler is at least partly arranged in the thermal insulation.
• the magnetic cooler thus is partly or completely arranged in the interior of the refrigerator and/or freezer, which provides the essential advantage that the cold conduits of the magnetic cooler need not be insulated. Due to the arrangement of the magnetic cooler in the interior, the cold conduits, i.e. the conduits carrying the cooled heat transfer medium, are located in the interior of the appliance, whereby a thermal insulation thereof can be omitted, and whereby an undesired input of heat into the heat transfer medium can be prevented.
• the appliance includes an interior to be cooled for accommodating the goods to be refrigerated and/or frozen, a magnetic cooler and a thermal insulation, which serves to reduce the input of heat into the interior of the appliance.
• the magnetic cooler is at least partly arranged in the thermal insulation.
• conduits carrying the cold heat transfer medium are at least partly arranged inside the interior of the appliance.
• conduits carrying the cold heat transfer medium are at least partly arranged in the thermal insulation of the appliance.
• conduits carrying the cold heat transfer medium are at least partly arranged inside the thermal insulation of the appliance and partly in the interior of the appliance, where they are connected with a cold heat exchanger.
• the arrangement of the cold heat exchanger largely can be as desired.
• the cold heat exchanger can for instance be arranged in the interior or also on the outside of the inner container or in the foam fill.
• conduits carrying the warm heat transfer medium are at least partly arranged outside the thermal insulation of the appliance, i.e. preferably on the outside of the appliance.
• conduits carrying the warm heat transfer medium are at least partly arranged in the thermal insulation of the appliance.
• the magnetic cooler is located in the thermal insulation of the appliance and from there the conduits carrying the cold heat transfer medium possibly lead through the thermal insulation into the interior of the appliance and the conduits carrying the warm heat transfer medium possibly lead through the thermal insulation to the outside of the appliance and there preferably are connected with the warm heat exchanger, by means of which heat is dissipated from the heat transfer medium.
• the magnetic cooler is arranged in the interior of the refrigerator and/or freezer. It is provided that the conduits leading to/from the magnetic cooler are not insulated.
• the length of the conduits to the cold heat exchanger is minimal, as the cold is produced at the point where it is needed.
• the magnetic cooler is positioned such that the same is located in the thermal insulation of the appliance. It is provided that the cold side of the magnetic cooler is located in the interior and the warm side of the magnetic cooler is located outside the appliance. There is no necessity to insulate the conduits of the warm and cold sides.
• the configuration of the refrigerator and/or freezer in accordance with the invention thus is comparatively simple, as it preferably is provided that a thermal insulation of the cold conduits, i.e. of the conduits of the magnetic cooler carrying the cold heat transfer medium, can be omitted.
• a thermal insulation of the cold conduits i.e. of the conduits of the magnetic cooler carrying the cold heat transfer medium.
