Definitions
- the invention relates to an evaporator for a compressor cooling device, which is made from a two-layer evaporator board, between which meandering refrigerant channels and an inlet and an outlet area for supplying and discharging the refrigerant are formed, with an intake pipe connected to the outlet area, which can be connected to a suction side of the compressor, and with a capillary tube for supplying liquid refrigerant into the inlet area, which passes through the suction tube outside the evaporator and can be connected to a condenser.
- Evaporators designed in this way are known, for example, from DE-B-1 242 646 and are used in many domestic refrigerators.
- the invention is now concerned with the refrigerant circuit, in particular with the refrigerant inlet into the evaporator, which takes place in the known cooling devices via a long throttle capillary tube corresponding to the required throttling effect, which according to the state of the art represents the refrigerant supply line.
- This throttle capillary tube is routed regularly into the inlet area of the refrigerant channel through a corresponding inlet thrust and, in the case of the so-called single-tube connection, also lies in the outlet area of the refrigerant channel with a section of its length.
- the refrigerant channel itself runs in a meandering manner in one of two aluminum sheets welded together, for example according to the so-called roll bonding process Manufactured, originally flat, then formed into the refrigerator compartment evaporator board and closes on the outlet side with an aluminum pipe socket, the so-called suction pipe, which is inserted pressure-tight into the channel end.
- the throttle capillary tube is so long today in the majority of the refrigerator types manufactured that it can only be accommodated to a small extent in the inlet area of the refrigerant channel of the evaporator and is largely outside the evaporator, often with a partial length of several meters. This part length is regularly wound up in a ring bundle to form a so-called capillary curl.
- a first production simplification could already be achieved by using throttle capillary tubes for evaporators of different types, all of which have an outer diameter of, for example, 1.9 mm, with inner diameters of, for example, 0.55 to 1.05 mm, which allow a type-dependent adaptation.
- at least connections of the throttle capillary tube or openings for this can be designed uniformly.
- the dragging of the capillary curl in the final stages of production continues to be a hindrance, just as the capillary curl unfavorably determines the packing density of the evaporators during transport to the cooling device manufacturers.
- the object of the invention is to simplify the variety in the manufacture of the evaporators caused by the numerous types of cooling devices and to take into account the consequences of using new refrigerants of lower viscosity.
- the generic evaporator is now characterized by the arrangement of a guide tube, the inner diameter of which is somewhat larger than the outer diameter of the capillary tube and the outer diameter of which is substantially smaller than the inner diameter of the suction tube, and the outer end of which opens into the inlet area, the inlet and outlet area being defined by the the outer tube wall of the guide tube and a constriction between the two evaporator boards are separated from one another, and the capillary tube is arranged in a first length section L1 of the guide tube, and ends therein, while the guide tube has a subsequent second length section L2 with a cross section which is wider than the capillary flow cross section, which is connected to the inlet area.
- a gap the size of a soldering fit is regularly set, the filling of which connects the tubes during soldering.
- the invention enables extensive standardization of the evaporator production and basically allows the separate production of the still throttle-capillary tube-free evaporator and the associated capillary tubes up to a final assembly in which the capillary tube is installed in the guide tube, that is, inserted as far as possible into or through this and finally being soldered to this
- the length, type and installation of the guide tubes in the evaporator boards can be reduced to a small number of construction variants, thus simplifying the production process.
- One embodiment of the invention provides that the guide tube has a constriction as a stop for the evaporator-side end of the throttle capillary tube.
- a curved intermediate pipe is arranged between the suction pipe and a suction line to the compressor, which is penetrated by the capillary pipe and the guide pipe, that the constriction seen in the inflow direction behind the opening of the intermediate pipe and thus within the through the intermediate pipe, the suction pipe and the inlet area of the Refrigerant channel formed area is. It is also expedient to expand the end of the guide tube in a funnel shape in order to make it easier to insert the throttle capillary tube into the guide tube and to solder both parts.
- the invention makes it possible to adapt easily to different design requirements of the cooling device manufacturers.
- An arrow 5 indicates the inflow direction
- another arrow 6 indicates the outflow direction.
- FIG. 1 shows a flat evaporator, the refrigerant channel 2 of which is partially indicated by a broken line.
- the suction tube 10 is held in the evaporator board via a soldered connection 16.
- a solder joint 17 holds the throttle capillary tube 7 in the guide tube 8.
- the constriction 19 in the inlet area 3 forms the inner fixation of the refrigerant supply line.
- the external fixation takes place in an opening 20 in the tube wall of the intermediate tube 11, into which the guide tube 8 is soldered.
- a suction tube 10 serves for the refrigerant outlet.
- the guide tube 8 is expanded at its outer end to form a funnel 21 and has a constriction 22 as a stop for the throttle capillary tube 7.
- a spike 23 is provided, into which the suction tube 10 is inserted with a solder fit. This enables a particularly reliable Cu / Al solder connection to be made.
