Definitions

  • the invention relates to an electric air heater, in particular for space heating systems for heating sucked from the outside cool outside air, which is promoted as supply air in closed rooms, especially building and vehicle spaces, with a plurality of electrically heatable profile strips of an electrically conductive plastic film, the Have a trapezoidal profile and each rotated by 180 ° against each other to a block with air channels and electrical connections welded together or glued together by means of an electrically conductive adhesive.
  • the invention has for its object to develop an electric air heater of the generic type, which is characterized by a high heat output, a uniform heat distribution and low surface temperatures.
  • the construction of the electric heating register according to the invention which is based on a composite of a plurality of profile strips of an electrically conductive heating foil block with air channels, characterized by a large, uniform temperature heating surface for warming up an air flow at a lower compared with known electric heating registers power consumption and lower space requirement.
  • the electric air heater 1 is preferably used in space heating systems for heating sucked from the outside cool outside air, which is promoted as supply air into a building.
  • the heating register 1 consists of a plurality of electrically heatable profile strips 2 with a trapezoidal profile 3 of an electrically conductive heating foil 4 made of plastic, which are assembled into a block 5 with parallel aligned air channels 6 having a tube-forming cross-section.
  • a plastic film is used in which carbon fibers are embedded in an organic or inorganic matrix.
  • the trapezoidal profile strips 2 are each rotated by 180 ° from each other to the block 5 welded together or glued together by means of an electrically conductive adhesive.
  • the electric Heilmotherregister 1 is equipped with two strip-shaped terminal electrodes 7, 8 made of metal or an electrically conductive plastic material, which are welded to the flat ends 9 of the profile strip 2, verclincht or glued by means of an electrically conductive adhesive.
  • the control of the switching on and off of the electrical heating coil 1 used for example in a space heating system the air ducts 6 are flowed through by the sucked in from the outside air in the direction of arrow a, which is conveyed as supply air into a building, is carried out by a temperature sensor, the temperature the inflowing supply air measures behind the heating coil and, when it falls below or exceeds the predetermined setpoint values by means of a relay, activates the corresponding power switches for switching on or off the heating register.
  • the electric Heilmoreregister 1 of several blocks 5 consist of profile strip 2 with continuous air channels 6.
