Definitions

  • the invention relates to a radiator for a heating system of a motor vehicle with a rib / tube block, which can be traversed by air to be heated, and which has at least one row of thermally conductive disposed between the ribs tubes.
  • Such a radiator is well known for motor vehicles.
  • the radiator has an assembled from round or flat tubes and corrugated fins or corrugated fins ribs / tube block, on both front sides of each a water box is connected.
  • coolant liquid is passed, which is heated by the cooling of the motor vehicle engine.
  • the corrugated fins or corrugated fins surrounding the tubes are traversed by air transversely to the tubes, the air being warmed up due to the heat-conducting properties of the corrugated fins or corrugated fins.
  • the generated engine heat is not sufficient to sufficiently heat the air flowing through the rib / tube block for heating the passenger compartment.
  • an effective heating power is achieved only after the engine has been warmed up, since the coolant fluid is only warmed up accordingly at this time.
  • the object of the invention is to provide a radiator of the type mentioned, which is electrically heated with simple structural measures and without requiring additional space.
  • the arrangement of the PTC heating elements in the ducts results in a compact structure with defined dimensions, which do not go beyond the dimensions of the tubes of the finned tube block.
  • the outer dimensions of the rib / tube block and thus the radiator do not change. Due to the heat-conductive connection of the cladding tubes with the ribs, i. the corrugated fins or corrugated fins of the radiator, the air flowing through the radiator is heated even when the tubes of the fin / tube block are either not flowed through by liquid or cold liquid.
  • the ducts with the PTC heating elements are arranged either in conjunction with pipes through which cooling liquid flows in the heating element, so that the PTC heating elements constitute an additional heating for the heating element.
  • the heating power of the PTC heating elements and the dimensioning of the associated cladding tubes enclosing ribs on the heat absorption capacity of the ribs flowing air are tuned. By this vote should be prevented that the PTC heating elements also heat adjacent, flowed through by cooling liquid pipes.
  • the PTC heating elements are intended solely for heating the air.
  • every second tube in the rib / tube block is replaced by a PTC heating tube having a cladding tube with PTC heating elements.

  • the PTC elements are preassembled into a plug-in component in the form of the frame and can be inserted in this compact design in a simple manner from an open end side into the corresponding cladding tube.
  • the PTC elements are arranged waterproof in the cladding tube. Corrosion, which could affect the functionality of the PTC elements, thereby avoided.

These ducts are integrated in the rib / tube block and are already involved in the production of the rib / tube block - initially hollow - with. Subsequently, the PTC heating elements are inserted by means of the compact and adapted to the inner dimensions of the ducts frame. According to the embodiment Fig. 1 each cladding is part of the rib / tube block and is soldered together with the flat tubes (6) and the corrugated fins (7).
