Definitions

  • the present invention relates to a PTC resistor.
  • PTC resistors used in various domestic applications are known, including room heating, water evaporation by refrigerator defrosting, etc.
  • resistors are based on PTC (positive temperature coefficient) technology; they not only emit heat but when a predetermined temperature has been reached they maintain it without requiring the use of an auxiliary thermostat and without the danger of overheating.
  • the resistor consists substantially of a steel tube filled with MgO and in which two mutually facing semicylindrical aluminium dissipators are inserted, between which a PTC insert is inserted and retained by two silicone rings.
  • the two dissipators are connected to the ends of two conductor cables covered by an insulating sheath which emerges from the tube via a discoidal portion of sealing material.
  • a PTC resistor comprising two metal dissipators between which a PTC insert is interposed and which are provided with conductor cables, characterised in that the dissipators and the insert interposed between them are housed in the interior of a heat conducting resin body.
  • the PTC resistor of the invention comprises substantially a PTC insert 2 interposed between two semicylindrical aluminium metal dissipators 4 to which the ends of two conductor cables 6 are connected.
  • the dissipators and the insert 2 are inserted into the interior of a substantially cylindrical body 8 obtained by injecting a heat conducting resin, for example an epoxy resin, into a mould in which the dissipators 4 with the insert 2 interposed have been previously placed.
  • a heat conducting resin for example an epoxy resin
  • the body 8 is inserted at one end into a connection sleeve.
  • the resin not only externally encloses the plates 4 but also lies within the space bounded by those surfaces of the mutually facing dissipators which are not occupied by the PTC insert, to provide considerable insulation even where the conductor cables 6 pass.
