Definitions

  • the invention relates to a cooling device with a heat-insulating housing, within which has at least three cooling compartments having a different temperature are arranged, each of which is equipped with a corresponding cooling capacity Evaporators are cooled, which are connected in series by one Refrigerant compressors are supplied with refrigerant, which is on the evaporator The highest cooling capacity provided injection point is supplied to the evaporators.
  • the invention has for its object in a refrigerator in accordance with the generic term of claim 1 with simple structural measures, the disadvantages of Avoid prior art.
  • the evaporator Are part of a one-piece evaporator board, which has a connecting web which has the evaporator of the highest cooling capacity with the evaporator medium Cold power connects fluidically and which is thermally insulated on the evaporator lowest cooling capacity is passed.
  • the vaporiser system is not only inexpensive to manufacture, but also easy to assemble attachable to the refrigerated goods container of a refrigerator. Furthermore, the one-piece evaporator board not only the storage, but also the feed to the assembly lines in the cooling unit production. Due to the heat insulating Insulation of the connecting web provided for refrigerant guidance opposite The refrigeration compartment at the highest temperature is an undesirable pre-evaporation of the refrigerant avoided before it is fed to the evaporator of medium cooling capacity, so that the refrigeration efficiency of the refrigeration system of the cooling device is significantly improved is.
  • the connecting web by cropping from the level of the evaporator the lowest cooling capacity and the highest temperature compared to the refrigerator compartment is heat insulated.
  • cranking the connecting web is special in terms of production technology easy to implement way both compared to the evaporator least Refrigeration capacity as well as the highest temperature compared to the refrigerator compartment decoupled. Furthermore, the evaporator board portion of the evaporator is the smallest Cooling capacity through this measure only with regard to its heat exchange surface marginally reduced.
  • a particularly cost-effective as well as comprehensive and comprehensive Decoupling the connecting web from the evaporator with the lowest cooling capacity and from the refrigerator compartment highest temperature is reached if after a next preferred Embodiment of the object of the invention is provided that the cranked Connection bridge embedded in the thermal insulation material of the housing is.
  • connecting piece integrally connected to the evaporator board, if after a Another preferred embodiment of the subject matter of the invention is provided is that the connecting web is at least essentially by a lateral Edge section of the evaporator board section forming the evaporator with the lowest cooling capacity is formed and separated from it by a kerf.
  • the connecting web on connecting sections of the evaporator highest and medium cooling capacity is coupled.
  • the connecting web is particularly simple Can be cranked out from the level of the evaporator with the lowest cooling capacity.
  • a refrigerant channel on the connecting web is particularly inexpensive to apply, if according to a last preferred embodiment of the subject of Invention is provided that the connecting web at least one in the roll bond process produced refrigerant channel.
  • FIG. 1 is a multi-temperature cooling device in a simplified schematic representation 10 shown with a heat-insulating housing 11, which has an outer panel 12, a thermal insulation layer 13 and produced by foaming an inner lining produced by chipless shaping of a plastic board 14 includes and which for receiving three heat insulating and separated refrigeration compartments arranged one above the other. Of these, the is higher than Freezer compartment 15, the middle one as normal refrigerator compartment 16 and the lower one as Fresh cooling compartment 17, which, like the other two cooling compartments 15 and 16 is lined by the inner lining 14.
  • Each of the cooling compartments 15, 16 and 17 is to maintain the intended refrigerator compartment temperature one to one one-piece evaporator board 20 associated evaporator, the to Cooling of the fresh cooler 17 serving evaporators than in the interior of the fresh cooler 17 arranged rear wall evaporator 21 is formed, while both the freezer compartment 15, which is essentially U-shaped and also evaporates the evaporator 23 used to cool the normal cooling compartment 16 as a so-called Cold wall vaporizer designed and heat insulation side on the inner lining 14 are set.
