Definitions

  • the invention relates to an air heater according to the preamble of claim 1.
  • Air heater with PTC heating elements for example inserted into the air conditioning box of a motor vehicle, and which are switched with a semiconductor switch, are known.
  • the standardized HL switches are in their own Installed housing, the switches in a large spatial Distance to the cooling medium can be arranged. Through the internal resistance the HL switch generates power loss in the form of warmth. It is common to include this power loss in that Conduct medium that is heated by the heating element shall be. Kick due to the large spatial distance numerous material transitions with long transport distances on, so that the overall heat transfer resistance is relative is great. For these reasons, powerful HL switches must be used be used.
  • the object of the invention is to circumvent the shown Disadvantages of providing air heaters which the heat transfer resistance between HL switch and Cooling medium improved, i.e. is humiliated with the aim to use less powerful HL switches.
  • FIGS. 1 to 5 explained in more detail.
  • FIG. 1 is a schematic longitudinal section through an assembly according to the invention with carrier material, HL chip and contact surfaces;
  • FIG. 2 is a top view of the assembly according to FIG Fig. 1;
  • Fig. 3 is a schematic longitudinal section through the Heating element with an integrated structural unit according to the invention.
  • FIG. 4 is a top view of the assembly according to FIG Fig. 2 with attached contacts;
  • Fig. 5 is a schematic longitudinal section through a Embodiment of an air heater according to the invention.
  • an HL switch chip 5 (only that Silicon platelets) used.
  • the chip 5 is on one good heat conductor 6 (preferably copper) applied. Of from there it is connected to the current output pad 2, the PTC elements (ceramics), which are the actual heating output provide, contacted; another connection is made on Control pad 7 and on the diagnostic pad 8, the connection preferably done in bond technique. All of these pads are good Heat conductor, preferably made of copper, to possibly over Dissipate the connecting cables well can.
  • the pads are placed on an electrically non-conductive Heat conductor 1, which is preferably made of ceramic, applied.
  • a contact material 3 is applied to the pads, which ensures that the thermal and electrical contact resistance to the contact strip 10, the battery exclusion leads, 11, which leads to the heating element, 13 (for control pad 7), 14. (For diagnostic pad 8) according to be minimized.
  • contact strips 10, 11, 13, which as Control strips and 14, which is designed as a diagnostic strip is made of a good heat conductor, preferably copper, are made, via the pads 2, 6, 7, 8 (see Fig. 2) placed.
  • FIG. 2 shown as a top view; here the training of the Current output pad 2 reproduced with contact material 3 resting on it; the chip 5 is on the output pad 2, the control pad 7 and the diagnostic pad 8, which in turn are each covered with contact material 3.
  • FIG. 5 schematically shows an embodiment of a Air heater according to the invention again, the inventive modular unit within the aluminum tube 9 arranged at its connection-side area and directly connected to the adjacent PTC heating elements 15 is; the heating output of the HL switch module and PTC elements 15 is dissipated to the environment via fins 16.
