Definitions

  • an evaporator for a two-temperature single-circuit refrigerator which has a freezer compartment and a section associated with its normal refrigerator compartment.
  • the freezer evaporator upstream of the defrostable normal refrigerator compartment evaporator in the refrigerant circuit is formed from an upright wall provided with refrigerant channels and two legs bent in the same direction, which serve as a ceiling and a floor and are also equipped with refrigerant channels.
  • the liquid refrigerant is significantly more difficult to enter the bypass if, according to an advantageous embodiment of the subject of the invention, that the transverse channel of the supply channel branches in the ceiling with the bypass in such a way that the refrigerant is able to enter the bypass after a sharp deflection.
  • a two-temperature single-circuit refrigerator 10 is shown, which, as usual, is equipped with an overhead freezer compartment 11 and a normal refrigerator compartment 13 which is arranged underneath and is separated from this by a heat-insulating intermediate wall 12.
  • the side walls of the normal cooling compartment 13 are provided with grooves 14 formed in the inner container of the refrigerator 10 for inserting shelves (not shown).
  • the refrigerator 10 which is equipped with a refrigerant compressor (not shown), is equipped with an evaporator 15 having two sections A and B and forming a system of coherent refrigerant channels, which evaporator 15 is formed by two plates connected by roller welding and receiving the refrigerant channels between them.
  • the sections A and B of the evaporator 15 are connected to one another by a web-like connecting bridge 19 (see in particular FIGS. 2 and 3).
  • the evaporator 15 shown in the development in FIG. 2 from a roll-welded plate is formed by bending along the bending zones located between the individual sections and delimited by dash-dotted lines to form a U-shaped profile, particularly shown in FIG. 1 in its use, the latter both ends are open.
  • the legs of the U-shaped profile bent in the same direction from the upright wall 17 have a slightly larger angle than 90 ° with respect to the upright wall 17 after the bending process.
  • the main channel 24 of the feed channel 23 continues seamlessly in a channel piece 27. After a relatively short path, this branches symmetrically into two channels 28, which run parallel to one another and run in a meandering manner in the bottom 18, each having the same channel cross section of the channel piece 17, the predominant length of which is arranged parallel to the free end of the bottom. Downstream after the branching, the channels 28 are briefly combined in a common channel bed 29, but then separated again. For this purpose, the channel bed 29 divides both upstream and downstream symmetrically with a channel cross section corresponding to the channels 28.
  • the channels 28 are at their output end connected in the bottom 18 by a substantially circular connection piece 30, which is arranged outside the bending zone, to a discharge channel 31 rising vertically in the upright wall 17 of the first evaporator section.
  • the outlet-side end of the feed channel 23 is connected to the outlet-side end of the discharge channel 31 in the ceiling 16, which is arranged directly next to it, by a bypass 35 which has an increased flow resistance and bridges the channel arrangement in the bottom 18, the bypass 35 at the junction of the transverse channels in the Auxiliary channels are connected to this.
  • the increased flow resistance of the bypass 35 is achieved in addition to a corresponding length arranged in turns and additionally by a reduced channel cross section compared to the channels of the feed channel 23 and the discharge channel 31, the ratio of the channel cross sections between the bypass 35 and the main or secondary channels of the Feed channel 23 or the discharge channel 31 is approximately 1: 5.
  • the duct-shaped duct section 36 belongs to a duct arrangement which is laid in turns in the ceiling 16 and has the same duct cross section as the enlarged main duct 32.
  • the outlet of the channel arrangement is connected to a channel line 38, which is directed downward on the connecting bridge 19 and is designed as a double channel across the bending zones, with the input of the section, which is not explained in more detail and forms the space evaporator and is designated by B (see also FIG 3).
  • the design of the feed channel 23 ensures that the liquid refrigerant flows mainly in its main channel 24 and, in relation thereto, a small proportion in its secondary channel 25.
  • the bypass 35 connected to the secondary duct 25, which is also equipped with an increased flow resistance in comparison to the duct cross sections of the feed duct 23, is only acted on with small amounts of liquid refrigerant, so that there is no loss of performance in the freezer compartment evaporator during the running time of the refrigerant compressor .
