  • the invention relates to a heat exchanger, in particular a condenser for a household refrigerator.
  • Refrigeration circuits of domestic refrigeration appliances include condensers whose function is to deliver a heat taken up by an evaporator and compressor to the ambient air.
  • Condensers may e.g. be attached to the rear wall of the household refrigerator. If the condenser is not on the back wall, but e.g. attached in an available space of the compressor room, it is possible to increase the interior of the household refrigerator. The space is relatively cramped.
  • the object of the invention is to provide a relatively compact heat exchanger, in particular a condenser for a household refrigerator.
  • the object of the invention is achieved by a heat exchanger, comprising a three-dimensionally spirally curved heat exchanger tube and arranged in the space bounded by the heat exchanger tube, attached to the heat exchanger tube fan.
  • the heat exchanger according to the invention is in particular a condenser for a household refrigerator.
  • Another aspect of the invention relates to a domestic refrigeration appliance, comprising a cold room and a cold room cooling refrigeration cycle with the liquefier according to the invention.
  • the heat exchanger or condenser according to the invention accordingly has the heat exchanger tube, which has been wound, for example, over a defined winding core in order to obtain the three-dimensional spiral shape.
  • the curved or possibly wound heat exchanger tube defines a space in which the fan according to the invention is arranged, wherein the fan is fastened or fixed eg by means of webs on the heat exchanger tube.
  • both the suction side and the pressure side of the fan are used for cooling the condenser or heat exchanger according to the invention.
  • This inventive arrangement of the fan allows a relatively space-saving design of the condenser or heat exchanger according to the invention, which can also be produced relatively inexpensively.
  • the size of the condenser or heat exchanger according to the invention can be changed, for example, by the number of pipe turns of the heat exchanger tube and / or the pitch of the heat exchanger tube. Over the length of the elongated heat exchanger tube, which defines its surface, and the size of the fan, the condenser according to the invention can be adapted to the respective requirements of Käteijns invention.
  • the heat exchanger tube may be made of various materials.
  • It is preferably made of metal, e.g. made of aluminum, copper or steel.
  • Condenser has the bent heat exchanger tube superimposed particularly semicircular first curved portions and superimposed particular semicircular second curved portions which are connected to particular rectilinear sections of the heat exchanger tube.
  • the pipe turns can be realized.
  • the heat exchanger or condenser according to the invention may preferably have a fastening device, eg webs, by means of which the fan is fastened to the heat exchanger tube.
  • the attachment can be realized for example by means of snap hooks.
  • the fastening device may, for example, have a first partial fastening device and a second partial fastening device, between which the fan is arranged or fastened.
  • the fastening device is fastened to the first curved and / or to the second curved section of the heat exchanger tube. If the fastening device comprises the two sub-fastening devices, then one of the two sub-fastening devices can be fastened to the first curved section and the other sub-fastening device can be fastened to the second curved section.
  • the fastening device or the two partial fastening devices can each be semi-cylindrical. Then it is possible, as provided according to an embodiment of the heat exchanger or condenser according to the invention, to fasten the fastening device with its circular segment-shaped lateral surface on the first curved or on the second curved portion of the heat exchanger tube. Does the fastening device the two
  • Partial fastening devices which are optionally formed in each case semi-cylindrical, then one of the partial fastening devices with its circular segment-shaped lateral surface on the first curved portion and the other partial fastening device with its circular segment-shaped lateral surface may be attached to the second curved portion of the heat exchanger tube. Between the two
  • the fastening device may be made of a noise-reducing or a sound-absorbing material, such as rubber. As a result, for example, a noise generated by the fan during operation of the condenser or heat exchanger according to the invention can be reduced.
  • the fastening device or the partial fastening devices can have, in particular, in their interior a liquid or solid heat-storing medium in particular, as a result of which the thermal properties of the heat exchanger or condenser according to the invention can be improved in a relatively simple manner.
  • the condenser or heat exchanger according to the invention can be set up freely, for example.
  • this has a shuttering within which the bent heat exchanger tube is arranged in particular attached.
  • the shuttering for example, to further increase the effectiveness of an airflow generated by the fan have a structure for the air flow generated by the fan conductive structure.
