Definitions

  • the invention relates to an evaporator arrangement for cooling one in one Refrigerator, such as a refrigerator, a fridge-freezer or the like, arranged cold rooms, with at least two in series arranged evaporators located in a single-circuit cooling system, from which one has a refrigerant injection point than the other evaporator, wherein the evaporators with one another through at least one refrigerant channel are connected.
  • a Refrigerator such as a refrigerator, a fridge-freezer or the like
  • evaporators located in a single-circuit cooling system, from which one has a refrigerant injection point than the other evaporator, wherein the evaporators with one another through at least one refrigerant channel are connected.
  • Cooling devices with at least two heat-insulating arranged separately from each other Cooling compartments, such as a normal refrigerator compartment and one arranged below Freezer or a freezer and one arranged below Normal cooling compartment
  • an evaporator which is usually through the circuit board sections an evaporator board formed and in series in a row Single-circuit cooling system are arranged.
  • the evaporator is connected in series Usually determined so that the evaporator has lower cooling capacity than the evaporator higher cooling capacity is connected downstream and for reasons of minimization of refrigerant flow paths between the two circuit board sections in vertical Refrigerant flows from bottom to top.
  • Such a flow of the downstream evaporator section entails that within the cooling compartment forms a temperature stratification, whereby the temperature in the The area of the ceiling of the refrigerator compartment is significantly warmer than that in the area of the refrigerator compartment floor temperature to be measured, so that there is a relatively high Temperature difference between the area close to the ceiling and the area near the floor
  • the energy consumption the device due to the permanent operation of the fan which is necessary for the function, undesirably increased.
  • the invention is based, an evaporator arrangement according to the task Preamble of claim 1 with simple constructive measures with regard to at least approximately uniform temperature distribution within the through to upgrade the downstream evaporator-cooled cooling compartment.
  • the evaporators have a different cooling capacity and that the refrigerant channel from the one provided with the injection point, a higher one Evaporator with cooling capacity on the top section in the installed position of the second evaporator, which has a lower cooling capacity and from this end section over the remaining section of the evaporator lower cooling capacity.
  • a particularly simple assembly of the evaporator arrangement in the refrigerator and at the same time a particularly secure position of the duct to avoid temperature stratification within the cooling surface to be cooled by the evaporator arrangement arises if according to a preferred embodiment of the object of the invention it is provided that the evaporator arrangement as an evaporator board with at least two circuit board sections with different cooling capacities.
  • the refrigerant channel has a higher cooling capacity from the circuit board section from the end of its placement on this board section at least in the vicinity of the end section facing away from it in the installed position of the evaporator arrangement
  • Lower section of the lower cooling capacity transferred is from where it is at least approximately meandering over the remaining area of the circuit board section of lower cooling capacity.
  • Such an evaporator arrangement represents a refrigeration appliance with an overhead one Normal cooling compartment and a fresh cooling compartment arranged underneath one at least approximately Even temperature distribution in the first refrigeration compartment is safe, because the With a higher specific weight, cold air acted on natural convection in the Normal refrigerator compartment.
  • the refrigerant channel on the circuit board section of lower cooling capacity its end section facing the circuit board section with higher cooling capacity has collectors designed in its course.
  • the refrigerant channel on the circuit board section has a lower cooling capacity whose end section facing away from the board section of higher cooling capacity in Near a suction point arranged there has a collector.
  • the refrigerant channel has a higher cooling capacity from the circuit board section from the end of its placement on this board section at least in the near area of the end section facing this circuit board section in the installed position the evaporator arrangement of lower-lying section of the board with lower cooling capacity is transferred from where it is at least approximately meandering over the remaining one Surface of the circuit board section of lower cooling capacity is performed.
  • the single figure shows a simplified schematic representation of an evaporator board with two connected, a normal freezer and a freezer assignable evaporator section.
  • FIG. 1 In the figure shown is a roll-bond process, for example for use in a refrigerator with a normal refrigerator compartment and a Fresh cooler suitable evaporator board 10 shown, which a first, for example has circuit board section 11 intended for cooling a fresh cooling compartment, the board surface 12 of a meandering from bottom to top Refrigerant channel 13 is covered, which starts from a throttle point 14 brought up to the circuit board section 11 on a connecting web 15 on the inflow side and on this to the lower one, in the installed position, from the connecting bridge 15 runs away from the end of the board surface 12.
  • the refrigerant channel 13 meanders upwards to the connecting web 15 facing end portion of the board surface 12 from where it then via the connecting web 15 to a second one, for example for cooling one Normal cooling compartment serving board section 16 is supplied. After entering to the circuit board section 16, this is directly in via its circuit board surface 17 transferred to the upper end section A facing away from the board section 11. Of this in the installed position of the evaporator board 10 in a cooling device, not shown Overlying end section A, the refrigerant channel 13 meanders over the remaining residual area B to the end of the board section 11 facing Circuit board section 16.
  • a collector 18 is connected in the refrigerant channel 13, from the drain-side end of the refrigerant channel 13 back into the upper end section A of the board section 11 transferred and from there to one on the both Board sections 11 and 16 interconnecting connecting web 15 lying Suction point 19 is brought up.
  • the invention differs from the exemplary embodiment described above also to form one with a fridge and freezer combination, for example a wire tube evaporator for the freezer compartment and a circuit board evaporator for the Cooling compartment can be used.
  • a wire tube evaporator for the freezer compartment and a circuit board evaporator for the Cooling compartment can be used.
  • the board-like evaporator assigned to the refrigerator compartment again at its end section facing the ceiling of the refrigerator compartment preferably cooled to at least a temperature stratification within the refrigerator compartment to oppose as far as possible and because of the specifically heavier To support cold air occurring natural convection.
