Definitions
- the present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, with a heat exchanger which comprises a pipeline through which a heat transfer medium flows.
- a heat exchanger which comprises a pipeline through which a heat transfer medium flows.
- Such heat exchangers are used in refrigerators as condenser, for discharging heat of the compressed refrigerant to the environment, or as an evaporator, for absorbing heat from a cooling space of the refrigerator by the expanded refrigerant used.
- condensers a so-called wire tube structure is widely used in which a refrigerant pipe is bent in one plane into meanders or loops, and the wire looped on the loops stabilizes the shape of the loops and enlarges the heat exchange surface.
- Object of the present invention is to provide a refrigeration device whose heat exchanger combines high efficiency with low production costs.
- an open-pore metal foam is formed on the pipe in a refrigeration device with a heat exchanger which comprises a pipe through which a heat transfer medium flows.
- the metal foam forms a plate-shaped body through which the pipeline is meandering out.
- the pipeline between two embedded in the body sections comprises a non-embedded portion to which fastening means can be attached if necessary, without affecting the structure of the metal foam.
- the tubing includes a plurality of straight, embedded sections, each connected by non-embedded arcuate sections.
- the heat exchanger described above is used in the refrigerator as a condenser.
- a metal foam is particularly an aluminum alloy into consideration.
- the pipeline is suitably made of a metal with a higher melting point than that of the aluminum alloy. Since the metal of the pipeline should advantageously also be good heat-conducting, in particular copper comes into consideration.
- the heat exchanger can be obtained in particular by molding the pipeline with the metal foam.
- Fig. 2 is a rear view of a refrigerator with a heat exchanger used as a condenser according to the invention.
- the heat exchanger shown in a perspective view in FIG. 1 comprises a flat cuboid block 1 made of metal foam, in particular an aluminum alloy, through which a plurality of pipe sections 2 extend in parallel.
- the mutually unconnected illustrated pipe sections 2 may be integrally connected with each other in series outside of the block 1; It is also conceivable that all are connected in parallel with an input and an output distributor.
- the open-pored metal foam of the block 1 has a very large specific surface area and can form an intimate connection with the metal of the pipe sections 2. Since it opposes air only a small flow resistance, a highly efficient heat exchange between the pipe sections 2 and the block 1 and flushing air is possible.
- FIG. 2 shows a plan view of the rear side of a refrigeration appliance, which as condenser carries a heat exchanger of the type described with reference to FIG.
- the flat plate-shaped block 1 of metal foam of this condenser has slightly lower Kantenlägen than the rear wall of the refrigerator, to which the condenser is suspended.
- a heat exchanger tube 3 extends in one piece continuously from a compressor 4 in meanders through the metal foam block 1 and via a throttle point to a (not shown) evaporator inside the refrigerator.
- the tube 3 extends predominantly in the form of rectilinear, mutually parallel pipe sections 5:
- the pipe sections 5 are shown in the schematic plan view of Figure 2 as solid lines to illustrate the course of the pipeline. in practice, the pipe sections 5 are embedded in the block 1 over their entire circumference and can not be seen from the outside.
- Two adjacent pipe sections 5 are each by a protruding from the block 1 pipe bend. 6 connected with each other.
- Pipe sections 8 and the bow 10 formed loop is essentially the
- the flow direction of the refrigerant through the condenser could also be opposite to that of the arrangement shown in FIG. 2, by a pipe piece 14 emerging at the bottom right corner of the block 1 with the pressure outlet of the compressor 4 and the pipe piece 12 via a restrictor connected to the evaporator inside the refrigerator.
