Definitions
- the present invention relates to an evaporation arrangement, which is used in a refrigeration device, in particular a household refrigeration device, to remove condensation water accumulating on one or more evaporators.
- Such an evaporation arrangement conventionally comprises an evaporation tray, which collects the condensation water and is arranged in close thermal contact with a heat source in order to heat the condensation water in the evaporation tray to such an extent that it evaporates at least as quickly as condensation water flows in from the evaporator or evaporators.
- a heat source that can be used to heat the condensed water is a heating tube immersed in the evaporation pan.
- the heating tube is conventionally made of copper, since copper conducts heat well and is sufficiently corrosion-resistant even when wet.
- the object of the present invention is therefore to provide an evaporation arrangement which achieves a high evaporation rate with low manufacturing costs.
- the object is achieved in that, in the case of an evaporation arrangement for a refrigeration device, in particular a household refrigeration device, with an evaporation tray and a heating tube running in the evaporation tray, the heating tube is a steel tube provided with a corrosion protection coating.
- the coating guarantees sufficient resistance of the steel pipe even in the event of long-term contact with the condensed water.
- the anti-corrosion coating can comprise an inner metal layer and an outer plastic layer, so that the inner metal layer still offers protection even if the relatively soft plastic layer has been damaged.
- metals are considered as the metal coating which are less noble than the steel of the steel tube in the order of the electrochemical series of voltages; such as in particular zinc, nickel or aluminum in pure or alloyed form.
- metallic coatings which predominantly contain zinc or aluminum, such as an essentially pure zinc coating, a zinc-aluminum coating, an aluminum-zinc coating, a zinc-magnesium coating or an aluminum-silicon coating, can be obtained by immersing the steel pipe , in particular a steel tube bent before being dipped into an intended shape, are applied to a melt.
- a galvanic application is also possible, in particular for a zinc coating, a zinc-nickel coating, a nickel coating or a copper-nickel coating.
- the plastic layer of the anti-corrosion coating preferably contains a thermoplastic, in particular a PA, PVC, PVDF, PTFE, ECTFE, PPS or polyolefin.
- the plastic layer can be produced by (co-) extrusion, by a fluidized bed sintering process or an injection process, it being possible to promote a uniform distribution of the applied plastic particles by opposing electrostatic charging of the steel tube and the plastic particles.
- a primer layer / primer can be provided as an adhesion promoter between the steel tube or its metal coating on the one hand and the plastic coating on the other.
- the heating tube preferably has at least two bends extending over the upper edge of an outer wall of the evaporation tray.
- a plurality of claws into which the heating tube is latched can be formed on a bottom of the evaporation tray.
- Fig. 1 shows a section of the machine room of an inventive
- FIG. 2 shows an evaporation arrangement of the refrigeration device from FIG. 1 in perspective
- Fig. 3 shows a cross section through a heating tube of the evaporation arrangement.
- Fig. 1 shows a section of the machine room 18 of a household refrigerator, seen from the open back.
- the machine room 18 is located on the rear of a body 19, in which one or more storage compartments accessible from the front are accommodated above the machine room.
- the machine room 18 contains a compressor 1, which is connected in a known manner to a condenser (not shown), possibly a frame heater, at least one throttle point and at least one evaporator arranged above the machine room to form a refrigerant circuit in order to cool at least one storage compartment of the refrigeration device.
- the compressor 1 comprises a compressor capsule 20, a pump and a motor driving the pump, which are hidden in the compressor capsule 20, and suction and suction leads out of the compressor capsule 20 Pressure connections 2, 3.
- the suction and pressure connections 2, 3 shown in FIG. 1 without connection are each connected to a refrigerant pipe in the fully assembled refrigeration device, via which refrigerant vapor is sucked in by the evaporator or compressed refrigerant is supplied to the condenser of the refrigeration device.
- An evaporation tray 4 is mounted on the capsule of the compressor 1 to form an evaporation arrangement.
- the evaporation tray 4 is arranged to collect condensate flowing from the evaporator through a passage in the housing. In the case considered here, it is fitted tightly on the capsule of the compressor 1 in order to collect waste heat from the compressor 1; However, it is also conceivable to mount it directly on the floor of the machine room, below the compressor 1.
- a dome 5 which is complementary to the shape of the compressor 1 and is tightly fitting on an upper part of the capsule 20 is formed on the bottom of the evaporation tray.
- a ditch 6 extends around the dome 5.
- the ditch 6 is adjoined to the outside by regions 7 in which the ground is approximately flat and is higher than at the bottom of the ditch 6 approximately vertical outer wall 8.
- a refrigerant line connects the compressor 1 to the condenser and, if present, to the frame heater and guides compressed, warm refrigerant during operation.
- This refrigerant line comprises a section which dips into the evaporation tray 2 and acts as a heating tube 9 which emits heat to the water of the evaporation tray 2.
- the heating pipe 9 can be arranged between an outlet of the compressor 1 and the condenser or between the condenser and the throttle point; if present, the frame heater can also be arranged in front of or behind the condenser and in front of or behind the heating tube 9, depending on the heating power required to prevent condensation on a front frame of the housing.
- a main part of the heating tube 9 runs in the interior of the evaporation tray 2 in a horizontal plane.
- this main part comprises a plurality of straight pipe sections 10, each of which extends in the longitudinal direction of the evaporation tray 2 extend and are interconnected by 180 ° bends 11.
- holding claws 12 are arranged, in the upwardly open notches of a keyhole-like cross section, the heating tube 9, in particular its straight tube sections 10, are engaged.
- the ends of the heating tube 9 are formed by two upright arches 13 which extend over the outer wall 8 of the evaporation tray 2.
- FIG. 3 shows a cross section through the heating tube 9.
- An innermost layer of the heating tube is formed by a thin-walled steel tube 14.
- the steel tube 14 can be single or double-walled.
- a metallic coating 15, in particular an essentially pure zinc coating, a zinc-aluminum coating, an aluminum-zinc coating, a zinc-magnesium coating or an aluminum-silicon coating is formed on the steel tube 14 as a first corrosion protection layer.
- Such a coating can be produced in a manner known per se by pulling the steel tube 14 through a melt of the coating. Galvanic generation is also possible, but is primarily considered for coatings with a significant proportion of nickel, since these are less suitable for dipping due to their high melting point.
- a primer layer 16 is applied here to the metallic coating 15, e.g. also by dipping or spraying.
- the primer layer 16 can be provided to improve the adhesion between the metallic coating 15 and a plastic coating 17 if necessary.
- the plastic coating 17 consists of a thermoplastic such as polyamide (PA), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), ethylene chlorotrifluoroethylene (ECTFE), polyphenylene sulfide (PPS) and their copolymers or polyolefin (LDPE, LLDPE) , HDPE, PP) and mixtures thereof.
- a thermoplastic such as polyamide (PA), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), ethylene chlorotrifluoroethylene (ECTFE), polyphenylene sulfide (PPS) and their copolymers or polyolefin (LDPE, LLDPE) , HDPE, PP) and mixtures thereof.
- the plastic coating 17 can be formed by extrusion, in particular by passing the steel tube 14 provided with the coating 15 through an extrusion nozzle and coating it in the process; Also suitable are vortex sintering processes in which the tube is heated to the softening temperature of the thermoplastic is passed through a fluidized bed made of plastic powder, or powder coating processes in which electrostatically charged plastic powder particles are attracted to the tube by applying an opposite charge and fused to a gap-free layer on the surface thereof. The heated tube is only used to allow the powder to adhere. This is followed by a baking or baking step. This is necessary to start the crosslinking of the plastic (approx. 120-220 ° C).
