Definitions

  • the invention relates to a refrigerator with an evaporator plate according to the preamble of claim 1, known from DE-A-19506904 ,
  • evaporator plate which is designed either as a so-called cold wall evaporator or as an indoor evaporator.
  • a coolant channel meandering from the height of the evaporator plate, starting from a refrigerant injection point arranged in the installed position of the evaporator plate at its upper end, and to supply the end of the refrigerant channel to a refrigerant suction point on the evaporator plate
  • Type of refrigerant channel guide entails that the lower end remote from the injection point in the mounting position of the evaporator plate with respect to the time from which set the refrigerant compressor in operation and thus the refrigerant channel is supplied on the evaporator circuit with liquid refrigerant, is significantly delayed cooling.
  • the invention has the object to improve an evaporator plate according to the preamble of claim 1 with simple constructive measures such that the disadvantages of the prior art are avoided.
  • the path of the refrigerant channel from the injection point to one of the surface end sections is particularly short, because the injection point situated upstream of the coolant channel is arranged within one of the two opposite surface end sections traversed by the coolant channel. Due to the minimized refrigerant channel guide from the injection point to one of theinstitunendabitese both provided with the injection point mecanicnendabêt as the oppositeêtnendabterrorism is very quickly with liquid refrigerant acted upon and thus cooled extremely quickly.
  • the injection point with the adjoining refrigerant channel can be arranged within the mounting end of the evaporator plate higher lying ceremonynendabiteses.
  • a cooling compartment of a refrigerator is cooled down particularly rapidly to the intended temperature when the evaporator plate has a rectangular blank and the narrower sides of the circuit board are essentially horizontal in the installed position of the evaporator plate, wherein the injection point is arranged within one of the surface end sections formed by the narrower sides of the sinker.
  • the evaporator plate can be produced if, according to a preferred embodiment of the subject matter of the invention, the evaporator plate is produced by the roll-bonding method or by the Z-bonding method.
  • an evaporator plate 10 produced according to the rollbond method which has a front view rectangular blank, the narrower sides of the rectangle associated circuit board sections serve asurbannendabête 11 and 12, which in dependence the height of the evaporator plate have a variable height h and which are referred to as so-called input or output of the evaporator plate.
  • the opposing surface end portions 11 and 12 which receive a middle board section 13 between them, in the installed position of the evaporator plate 10 in a not shown refrigerator higher lying felicitnendabêt 11 provided with an injection point 14 for refrigerant.
  • a refrigerant channel 15 is fluidly connected, which passes through the overheadassinendabites 11 in the present case in the manner of a loop and which is transferred at the end of the loop of this mecanicnendabrough 11 in the installation position of the evaporator plate 10 lying below the bottom end portion 12.
  • the refrigerant passage 12 extends in a meandering manner over the height of the central sinker section 13, before it is connected on the output side to a suction point 16 provided on the surface section 11.
  • Fig. 2 shows how Fig. 1 in a simplified schematic representation of a second embodiment of a rectangular blank having evaporator plate 20, whose the narrower sides of their rectangle facing edges serve as professionnendabterrorisme 21 and 22, which have a different height h depending on the height of the evaporator plate ,
  • a middle board portion 23 is provided, which is significantly enlarged in terms of its area with respect to the surface of theinstitunendabête 21 and 22.
  • the sinker section 23 has an approximately centrally located to its height refrigerant injection point 24, to which a refrigerant passage 25 is fluidly connected.
  • the refrigerant channel 25 extends into a refrigerant suction point 26 arranged within the sinker section 23.
  • the minimally imminent direct transfer from the refrigerant injection point 24 located in the middle sinker section 23 into the adjacent end section 21 becomes the first and short interval thereafter with the facing end section 22 liquid refrigerant is applied and thus cooled, while the central board portion 23 is acted upon only after the proceedingsnendabête 21 and 22 with liquid refrigerant.
  • the central board section 23 experiences a kind of precooling effect, which is brought about by the heat conduction of the aluminum evaporator plate 20 produced, for example, by the rollbond method.
  • FIG. 3 shows a coordinate system for illustrating evaporator surface temperatures in evaporator plates according to the prior art.
  • the surface temperature in ° C of the evaporator plate is plotted on the ordinate and the time t in minutes on the abscissa.
  • the curve of the surface temperature measured at the evaporator entrance differs significantly from the curve determined for the surface temperature at the evaporator exit (corresponding to the bottom end section), the surface temperature at the evaporator exit being close to zero has the magnitude of the temperature at the evaporator inlet at the end of the compressor run time.
  • the graph of FIG. 4 shows in curves the course of the surface temperature at the output or input of an evaporator plate according to the invention.
  • the surface temperature of the evaporator plate is also plotted over the compressor running time.
  • the curve determined for the surface temperatures at the evaporator inlet or at the evaporator outlet follows as far as possible the curve, which was determined on the input side of the evaporator plate.
  • the leadership of the refrigerant channel 15 and 25 is the corresponding refrigeration demand at the solicitnendabêten 11 and 12 or 21 and25 adaptable.
