  • 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 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.
