Definitions

  • the invention relates to an evaporator arrangement, in particular for compressor-operated household refrigeration appliances with at least two fluidically connected, series-like, circuit board-like evaporator sections with a different refrigeration capacity, the refrigerant channel arrangement of which, controlled by control elements, can be acted upon with refrigerant conveyed by a refrigerant compressor, which is supplied to the evaporator sections via injection points is discharged via a suction line common to the evaporator sections.
  • Multi-temperature cooling devices are known, the thermally separated cooling compartments of which are kept within their intended temperature range by means of an evaporator arrangement with a corresponding number of evaporator sections with different cooling capacities.
  • the evaporator sections can be acted upon individually with refrigerant by control elements designed as solenoid valves and for this purpose provided with an injection point, the evaporator sections of lower cooling capacity, such as, for example, the fresh cooling compartment and normal cooling compartment, being connected upstream of the evaporating section of higher cooling capacity, such as, for example, a freezer compartment, in order to continuously flow with refrigerant through the evaporator section of higher cooling capacity.
  • the invention is based on the object of proposing an evaporator arrangement in which the disadvantages of the prior art are avoided with simple structural measures.
  • the evaporator section of higher cooling capacity in the inflow-side region of its refrigerant channel arrangement has a connection point serving for the fluidic connection of the evaporator sections, which is provided in a monotonically falling section of the refrigerant channel arrangement.
  • the solution according to the invention ensures, on the one hand, that the evaporator section of higher refrigeration capacity is acted upon by liquid refrigerant even when the evaporator sections of lower refrigeration capacity are in operation and is therefore always cooled as well.
  • the evaporator arrangement is also insensitive to a certain inclination of the refrigeration device.
  • evaporator sections are provided, one of which has a higher cooling capacity than the other two and each of the other evaporator sections is connected in series in terms of refrigeration technology, both evaporator sections having lower cooling capacity being connected by a single connection point the evaporator section of higher refrigeration capacity are fluidly connected.
  • connection of the two evaporator sections of lower cooling capacity to the is particularly simple and yet secure Evaporator section of higher refrigeration capacity if, according to a next advantageous embodiment of the object of the invention, it is provided that the connection point, upstream of the flow direction of the refrigerant, is preceded by a piece of refrigerant channel in which the refrigerant flow from each refrigerant channel arrangement of the evaporator sections of lower refrigeration capacity is brought together and introduced into the connection point.
  • the evaporator section of higher refrigeration capacity is designed as a C-shaped freezer compartment evaporator having a bottom, a top and a rear wall section, in which the connection point is arranged within the rear wall section.
  • the evaporator section of higher cooling capacity and the evaporator sections of lower cooling capacity are arranged within a one-piece evaporator board and that each of the evaporator sections within the one-piece evaporator board is provided with an injection point provided on its heat exchange surface.
  • the single figure shows a printed circuit board-like evaporator with three evaporator sections arranged within the surface of the printed circuit board.
  • An evaporator arrangement 10 intended for use in a three-temperature refrigeration device is produced by pressure welding two two-piece aluminum sheet plates which are formed in one piece and are arranged directly one above the other and is equipped with evaporator sections of different cooling capacity.
  • the evaporator section with the lowest cooling capacity is designed as a cooling compartment evaporator 11, which is provided on its free, longer rectangular side with a connection point 12, into which a throttle pipe (not shown) serving as an injection pipe can be inserted.
  • a refrigerant channel arrangement 13 Connected to the connection point 12 is a refrigerant channel arrangement 13, the outlet-side end of which is designed as a double channel and runs along a connecting web 14 which is integrally connected to the refrigerator compartment evaporator 11.
  • a vaporizer section designed as a zero-degree vaporizer 15 via holding webs, not shown.
  • the zero degree compartment evaporator 15 faces the refrigerator compartment evaporator 11 Section side on a connection point 16, which, like that of the refrigerator compartment evaporator 11, is used for insertion for a throttle tube, not shown, which is used as an injection pipe and which is fixed pressure-tight in the connection point by means of a soldered connection.
  • connection point 16 Connected to the connection point 16 is a refrigerant channel arrangement 17 which runs in turns over the heat exchange surface of the zero-degree compartment evaporator, the outlet-side end of which branches into a double channel 18 which is connected along a connecting web which is integrally connected to the zero-degree compartment evaporator 15 19 runs.
  • this is connected in one piece to an evaporator section which is arranged adjacent to the evaporator section and serves as a zero-degree compartment evaporator 15 and which has the highest cooling capacity.
  • This vaporizer section is designed as a freezer compartment vaporizer 20 and is [-shaped in its ready-to-install shape.
  • the freezer compartment evaporator 20 has a bottom section 21, a rear wall section 22 and a ceiling section 23, which serve as heat exchange surfaces, an injection point 24 being provided in the ceiling section 23, which is produced by embossing a throttle tube (not shown). From a fluidic point of view, the injection point 24 is followed by a refrigerant channel which is laid in turns over the major part of its length, which extends in one go continuously across the three regions of the freezer compartment evaporator 20 and which forms its refrigerant channel arrangement 25. In the area of its refrigerant inflow via the injection point 24, in the rear wall area 22 arranged vertically in the installed position of the evaporator arrangement 10, this is provided with a connection point 26 designed as an inflow opening.
  • connection point 26 is opposite to the refrigerant flow direction generated by the compressor
  • a refrigerant channel piece 27 is connected upstream, which is used for the fluidic connection of the refrigerant channel arrangements 13 or 17 of the refrigerated compartment evaporator 11 or the zero-degree compartment evaporator 15 to the refrigerant channel arrangement 25, so that one of these refrigerant channel arrangements 13 or 17 is connected in series in front of the refrigerant channel arrangement 25 lies.
  • the refrigerant channel arrangements 13 and 17 are each led to the refrigerant channel piece 27 via a single-way refrigerant channel, which in turn connects to the double channel provided on the respective connecting web 14 or 19.
  • the refrigerant channel adjoining the double channel in the connection area of the connecting web 14 first passes through the bottom area 21, then the rear wall area 22 and then the ceiling area 23, from where it then merges again into the rear wall area 22 for connection to the refrigerant channel piece .
  • the refrigerant channel connecting to the double channel arranged there in the connection area of the connecting web 19 passes through the rear wall area 22, then through the ceiling area 23, from where it then merges into the rear wall area 22 and opens into the refrigerant channel piece 27.
  • the refrigerant channel arrangements 13 and 17 are connected to the refrigerant channel arrangement 25 at its vertically arranged section in the rear wall area 22, it is prevented that liquid refrigerant can flow into an evaporator which is currently coupled out of the refrigerant circulation. In this way it is ensured that in this evaporator, which is inactive for defrosting purposes, for example, no disturbances caused by inflowing liquid refrigerant occur in the form of a constantly increasing formation of ice at the entry point to this evaporator.
  • freezer compartment evaporator 20 such as the refrigerator compartment evaporator 11 and the zero-degree compartment evaporator 15 can only be designed as a flat board surface.
