Definitions
- the present invention relates to a suction throttle pipe assembly for a refrigerator and an evaporator, in which such a structure is used, or a household refrigerator with a suction throttle pipe assembly or with an evaporator.
- a conventional plate-type evaporator comprises a base plate on which a refrigerant pipe passes, and a throttle pipe via which the refrigerant pipe is fed with compressed refrigerant, and a suction pipe for sucking in the refrigerant
- Evaporators expanded and heated refrigerant. By placing the suction tube and the throttle tube in close thermal contact with each other, the compressed can
- Refrigerant are pre-cooled in the throttle tube, so that when it expands from the throttle tube into the refrigerant tube of the evaporator plate in, reaches a low temperature.
- the object of the present invention is therefore to specify a suction throttle pipe construction in which contact corrosion of the pipes is reliably prevented, without the efficiency of the heat exchange between the pipes being appreciably impaired as a result.
- At least one of the tubes is provided with an electrically insulating plastic coating in a suction throttle pipe assembly with a suction pipe and a throttle tube, which are in contact with each other and made of two different metals.
- a plastic coating is easy to remove, so that it can be mounted as a continuous layer on a pipe from which subsequently throttle pipes can be cut in the required length.
- the plastic coating is a lacquer layer, in particular a lacquer layer, as conventionally used in the production of electrically insulated enameled wires.
- the plastic coating in particular such a coating layer, preferably contains a polymer material selected from polyesters, polyurethanes, polyamides, polyimides, their mixtures and copolymers.
- the thickness of the plastic coating is low, preferably at most about 50 microns, so that the heat transfer between the two tubes is not significantly affected by the presence of the plastic layer.
- the plastic coating on the throttle tube in particular only on this, attached.
- a smaller amount of coating material is needed for the coating of the throttle tube than for the coating of the substantially further suction tube;
- known techniques for painting wire can be transferred to the painting of the thin, flexible throttle tube without significant adjustments.
- suction tube and throttle tube are preferably held together by an adhesive tape.
- an adhesive tape In order to ensure a long-term stability of the bond, it is preferable to use a metal adhesive tape, in particular an aluminum adhesive tape.
- the plastic coating of the throttle tube is preferably mechanically removed at a connection thereof to the evaporator plate.
- the use of heat or solvents would be considered in principle for the removal of such coatings, but it is difficult to ensure that no solvent residues or possibly chemically aggressive combustion residues of the plastic coating on or in the throttle tube remain, the later of the trigger of corrosion or Leaking or could clog the throttle pipe.
- the suction throttle pipe assembly according to the invention or a vaporizer using this finds use in household refrigerators, because in a simple and reliable manner the problem of contact corrosion in a large number of devices is eliminated cost-effectively.
- FIG. 1 shows a cross section of a suction throttle pipe construction according to the invention.
- Fig. 2 in an exploded view of the connection region between the suction throttle pipe assembly and an evaporator plate.
- Fig. 1 shows in cross section a throttle pipe or capillary 1 made of copper for the supply of an evaporator with compressed refrigerant and the throttle tube 1 is covered over its entire circumference by an electrically insulating paint layer 2.
- Suitable for the production of the lacquer layer 2 is any lacquer which can also be used for the production of electrically insulated enameled wires, in particular based on polyester, polyurethane, polyamide, polyimide, mixtures or copolymers thereof.
- the lacquer layer 2 with a thickness of typically about 50 micrometers maximum is flexible, so that the throttle tube 1 can be bent as needed without the lacquer layer 2 bounces off.
- a suction tube 3 made of aluminum, whose diameter is greater by a multiple than that of the throttle tube 1.
- An aluminum adhesive tape 4 adheres along its longitudinal edges on the suction tube 3, while a central portion of the adhesive tape 4 wraps around the throttle tube 1 and keeps it pressed against the suction tube 3. This ensures intimate thermal contact between the pipes 1, 3.
- the suction tube 3 is uncoated.
- Condensation which can be reflected outside the suction tube 3 under certain operating conditions, is kept away from the throttle tube 1 by the lacquer layer 2, so that the formation of a galvanic cell between the aluminum of the suction tube 3 and the copper of the throttle tube 1 is excluded.
- Fig. 2 shows - partially cut - a fragment of a heat exchanger with a base plate 5 and inlet and outlet sections 6, 7 of a soldered on the base plate 5 refrigerant raw rs 8.
- the refrigerant tube 8 is shown in a parallel to the base plate 5 section. Its inlet section 6 can be tapered in order to receive a form-fitting part of an end section 9 of the throttle tube which has been freed from the lacquer layer 2;
- the cross-section of the refrigerant tube 8 on the entire base plate 5 is constant, and a tight connection of the throttle tube 1 is made by an adapter body 10 which is provided to be inserted tightly into the inlet portion 6 and in turn the end portion 9 in one to accommodate the inner bore 11 tight.
- the throttle tube 1 is cut from a continuously painted, long tube in the required length. It must therefore be eliminated before mounting the throttle tube 1, the paint layer 2 in the end portion 9. This is done by mechanical means, for example by grinding or twisting. A stripping of the paint layer when pushing through the end portion 9 by a tightly tolerated opening comes into consideration.
- This opening may in particular be the bore 1 1 of the adapter body 10; a sealing soldering of the end portion 9 on the adapter body can then take place at the inlet portion 6 facing side of the adapter body 10, around a protruding tip of the end portion 9 around. Subsequently, the adapter body 10 is in turn inserted into the inlet section 6 and soldered thereto.
