Definitions

  • the present invention relates to an electric heating device for air heating, which is particularly suitable for use as electrical auxiliary heating in motor vehicles and which has a holding device which holds a layer structure with a plurality of heat-generating elements and arranged between these heat-emitting elements.
  • the individual layers of this layer structure can be glued together and / or pressed against each other under bias of a spring when the layer structure is received in a holding device forming the closed frame.
  • Individual electrical heat-generating elements are kept isolated from each other in the holding device and usually at one end of the layer structure, e.g. provided in the longitudinal direction of the layer structure with electrical contact elements, via which certain electrical heat-generating elements can be electrically connected to the electrical system of the vehicle.
  • Resistance heating elements preferably PTC heating elements are generally used to form the heat-generating elements, in which due to their control characteristic overheating of the heat-generating elements is reliably avoided.
  • Each of the heat-generating elements usually consists of a plurality of PTC heating elements arranged one behind the other in the longitudinal direction of the layer structure. These lie flat against an electrically conductive and usually good heat conductive surface, through which the heat-generating elements are energized and which is dissipated by the heat generated by means of line.
  • This flat surface is regularly formed by the heat-emitting elements, which have on their outside a voltage applied to the heat-generating elements band, which is connected as a separate component or integrally with substantially transverse to the layer structure extending heating fins or lamellae. If the flat surface is formed by flat metal strips, these are usually assigned to the heat-generating elements.
  • a generic electric heating device is known for example from EP 1 157 867, in which a control device for controlling the heat-generating elements is disposed within the frame and formed by power transistors having on their side facing the layer structure cooling fins, which within the frame for dispensing heat generated by the transistors to the electrical heater transverse to the frame plane flowing air exposed.
  • the cooling fins are for this purpose in windows which are recessed on the frame.
  • EP 1 492 384 which can also be regarded as generic and in which the control device is received in the frame and also formed by power transistors. Accordingly, there is also the need to give off heat generated by the transistors to the air flowing through the electric heater.
  • This known electric heater bridge a plurality of longitudinal members of the holding device, the distance between transverse beams, which serve the electrical connection and the attachment of the electric heater to a vehicle.
  • the longitudinal beams a plurality of successively arranged PTC heating elements are provided, which are connected on both sides flat to electrical guide elements of different polarity. These guide elements are formed in the longitudinal direction of the spars. As heat-emitting elements slats are pushed onto the longitudinal beams, which form a layer structure in the manner of a lamella stack for themselves.
  • the slats extend between the heat-generating elements, but also extend beyond the outer spars on the outside, so that the frame formed by the longitudinal and transverse struts has no smooth outer side, but rather has the free ends of the heat-emitting slats on its longitudinal sides. Accordingly, the frame known from EP-1 390 219 can be installed with its transverse spars relatively close to a ventilation duct of a vehicle.
  • the long sides of the electric heater must meanwhile be formed by the walls of the vehicle-side ventilation duct, which is not disadvantageous in principle.
  • the arrangement and the permanent contacting of the PTC heating elements in the bars has proved to be a problem in this prior art heating device.
  • the electrical heating devices known from the prior art have the disadvantage, on the one hand, that at least the cooling elements of the power transistors must be arranged within the frame and flowed through by the air flowing through, which precludes a compact construction of the electric heating device.
  • the power transistors are also expensive electronic components, which are sometimes prone to failure, and the arrangement and sealing of the cooling elements makes design effort required, which brings an increase in manufacturing costs.
  • not all of the air-flowed inner area of the frame is formed by the heat-generating and -offending layer structure, whereby the heat output per air-flow area unit is reduced.
  • the present invention is based on the problem of providing an electrical heating device which avoids the above disadvantages and which can be manufactured in a cost-effective manner and moreover enables effective utilization of the interior of the frame which is flown by the air.
  • the present invention provides an electric heating device having the features of claim 1.
  • the electric heater according to the invention differs from the generic state of the art in that the control device comprises a relay.
  • the heating device according to the invention uses cost-effective relay for controlling the heat-generating elements. These relays are held by the holding device, but are preferably not even partially exposed within the air flow, so that the entire area of the holding device through which the air flows can be used optimally for the arrangement of the layer structure and for targeted heating of the air flowing through.
  • the relay or the relays may be arranged in the holding device forming supporting parts or surrounded by these, for example, be accommodated in the housing forming the frame. It has proved to be advantageous to arrange the at least one relay on a printed circuit board, which receives in the longitudinal direction of the layer structure on this extended electrical contact elements.
  • These electrical contact elements are formed in a simple manner by extending individual metal strips, which are arranged as separate parts between the heat-generating elements and the heat-emitting ribs, beyond the layer structure addition.
  • the electrical contact elements are preferably guided to the outside of the frame and arranged there in the circuit board, which also carries the at least one relay.
  • the essential control elements of the electric heater are outside the frame and are accessible for repair work from the outside.
  • the assembly and replacement of a possibly defective relay is simplified in that the at least one relay on the side facing away from the layer structure of the circuit board is arranged according to a preferred embodiment of the present invention.
