Definitions

  • the invention relates to an evaporator arrangement, in particular for compressor operated household refrigeration appliances, with at least two fluidically connected in series connected, having a different cooling capacity, circuit board-like evaporator sections, their refrigerant channel arrangement controlled by tax organs with from one Refrigerant compressor pumped refrigerant can be acted upon which is above the respective evaporator sections assigned injection points to the evaporator sections and via a common to the evaporator sections Suction line is discharged.
  • Evaporator arrangements with evaporator sections connected in series different cooling capacities are known for example from DE 32 24 452 A1.
  • Multi-temperature cooling devices are known, their thermal Cold compartments separated from one another using an evaporator arrangement with a corresponding number of evaporator sections different cooling capacity within your dedicated temperature range are maintained.
  • the evaporator sections are in such multi-temperature refrigeration devices by control elements designed as solenoid valves individually charged with refrigerant and for this purpose provided with an injection point, the evaporator sections lower cooling capacity, e.g. Fresh cooler and normal refrigerator compartment the evaporator section of higher cooling capacity, such as a freezer in series are upstream to the evaporator section higher To flow through refrigeration capacity constantly with refrigerant.
  • the invention has for its object an evaporator arrangement propose which with simple constructive Measures avoided the disadvantages of the prior art are.
  • the evaporator section of higher cooling capacity in the inflow side Area of its refrigerant channel arrangement at least has an approximately vertically arranged section, which with a for fluidic connection of the Connection point serving evaporator sections is equipped, which is arranged in a monotonously falling Section of the refrigerant channel arrangement of the Evaporator section higher cooling capacity is provided.
  • the solution according to the invention ensures that the evaporator section has higher cooling capacity even when operating the evaporator sections with lower cooling capacity charged with liquid refrigerant and thus is always chilled.
  • the evaporator arrangement is also related insensitive to a certain inclination of the refrigerator.
  • the invention provides that three evaporator sections are provided, one of which has a higher cooling capacity than the other two and each of the others Evaporator sections in refrigeration in series connection is connected downstream, both evaporator sections smaller Cooling capacity through a single connection point with the evaporator section with higher refrigeration capacity are connected.
  • connection of the is particularly simple and yet secure two evaporator sections with lower cooling capacity at the Evaporator section higher cooling capacity, if after a next advantageous embodiment of the subject of Invention is provided that the junction counter a refrigerant channel piece in the direction of flow of the refrigerant is upstream in which the refrigerant flow from each refrigerant channel arrangement of the evaporator sections lower cooling capacity merged and into the connection point is initiated.
  • the object of the invention is that the evaporator section higher cooling capacity than C-shaped, a floor, a ceiling and a rear wall section Freezer compartment evaporator is executed, in which the connection point within the rear wall section is arranged.
  • the invention provides that the evaporator section higher cooling capacity and the evaporator sections lower cooling capacity within a one-piece evaporator board are arranged and that each of the evaporator sections inside the one-piece evaporator board with an injection point provided on its heat exchange surface is provided.
  • the only figure shows a board-like evaporator in stretched representation with three within the board area arranged evaporator sections.
  • certain evaporator arrangement 10 is through Pressure welding of two one-piece, immediate stacked aluminum sheet boards produced and with evaporator sections with different cooling capacities fitted. Of these, the lowest is the cooling capacity having evaporator section as a refrigerator compartment evaporator 11 executed, which on its free longer Rectangular side is provided with a connection point 12 in which is an unillustrated one serving as an injection pipe Throttle tube can be inserted. At junction 12 is followed by a refrigerant channel arrangement 13, the outlet end is designed as a double channel and along one piece connected to the refrigerator compartment evaporator 11 Connecting web 14 runs.
  • the freezer compartment evaporator 15 points to the refrigerator compartment evaporator 11 Section side on a junction 16, which like that of the refrigerator compartment evaporator 11 for insertion for as Injection tube used, not shown Throttle tube is used, which means in the connection point a solder joint is set pressure-tight.
  • the junction 16 is one in turns over the heat exchange_ Area of the zero-degree compartment evaporator-running refrigerant channel arrangement 17 connected, the outlet end branches into a double channel 18, which runs along a integrally connected to the zero degree compartment evaporator 15 Connecting web 19 runs.
  • This evaporator section is designed as a freezer compartment evaporator 20 and in its ready-to-install shape [-shaped.
  • the Freezer compartment evaporator 20 has a bottom section 21, one Rear wall section 22 and a ceiling section 23, which serve as heat exchange surfaces, being in the ceiling section 23 an injection point 24 is provided, which generated by embossing a throttle tube, not shown is.
  • the injection point 24 is fluidly connected one over most of its length refrigerant channel laid in turns, which is located in one train continuously across the three areas of the freezer evaporator 20 extends and which its refrigerant channel arrangement 25 forms. This is in the range of yours Refrigerant inflow via the injection point 24, in the installed position the evaporator arrangement 10 arranged vertically Rear wall area 22 with an inflow opening Provide connection point 26.
  • the junction 26 is opposite to the direction of refrigerant flow generated by the compressor upstream of a refrigerant channel piece 27, which for fluidic connection of the refrigerant channel arrangements 13 or 17 of the refrigerator compartment evaporator 11 or Zero degree compartment evaporator 15 to the refrigerant channel arrangement 25 is used so that one of these refrigerant channel arrangements 13 or 17 in series connection in front of the refrigerant channel arrangement 25 lies.
  • the refrigerant channel arrangements 13 and 17 are each for the purpose of connecting them unique refrigerant channel, which in turn to the provided on the respective connecting web 14 or 19 Double duct connects to the refrigerant duct piece 27.
  • [-shaped freezer compartment evaporator 20 can be such as the refrigerator compartment evaporator 11 and Zero degree compartment evaporator 15, only as a flat board surface be trained.
