Definitions

  • the invention relates to a heating device with a PTC (ceramic PTC) heating element, as specified in the preamble of claim 1.
  • PTC semiconductor PTC
  • DE-OS 27 43 880 namely the main patent for the present invention, describes a heating device with an optimized heating element made of thermistor material.
  • the PTC thermistor heating element has a thickness of only 0.5 to 2 mm with a specific electrical resistance of the PTC thermistor material kept in a relatively narrow range, which must also have a Curie temperature which is at least 50 ° higher than the switch-off temperature provided for the heating device. This switch-off temperature is z.3. for boiling water 100 ° C (373 K).
  • Another important feature of a heating device according to the above-mentioned DE-CS is that on both sides of the disc of the PTC heating element, heat dissipation is as large as possible is present. The same amount of heat dissipation on both sides takes precedence over extremely good heat dissipation on only one side.
  • the present invention is based on the consideration of providing the manufacturer of devices with electrical heating devices with such a PTC heating device, which is comparatively similar to one Wire heater with the electrically insulating body around it.
  • the connecting lugs led outwards are at a distance from one another which corresponds to the VDE regulations, because in the case of the disk-shaped PTC thermistor heating elements, the two electrodes located on the top of the PTC thermistor disk are only a maximum of 2 mm apart.
  • the electrical connecting lugs of the sandwich are at a sufficiently large distance from one another without losing the advantage of the small volume of the PTC thermistor heating element for comparatively high heating power.
  • FIG. 1 shows a perspective view of a ready-to-install sandwich according to the invention to be used as an electrical heating device.
  • FIG. 2 shows a sectional view II-II of a sandwich according to FIG.
  • Fig. 1 shows the degree of perfection that enables the sandwich with PTC heating element to be easily installed.
  • the upper plate made of sintered aluminum oxide, which is visible in the perspective view, is designated by 2. Such a sintered body has high mechanical strength.
  • the frame made of plastic material is designated by 12, with which a tight, in particular liquid-tight, connection is made between the upper and the lower aluminum oxide plate (not visible in FIG. 1).
  • connection lugs for the supply of the operating voltage, e.g. 220 volt mains voltage.
  • the required minimum distance from one another can be maintained without difficulty after a sandwich as shown in FIG. 500 watt heating power (for a switch-off temperature of e.g. 100 ° C) has dimensions in the order of 35 by 35 mm.
  • FIG. 2 Details of the structure of a sandwich according to FIG. 1 can be seen from the sectional view in FIG. 2, in which the PTC heating element according to the DE-OS mentioned at the beginning is designated by 1.
  • the upper and lower aluminum oxide plates are designated by 2.
  • a lead-tin solder with a preferably relatively high lead content such as e.g. a solder with 95.5% Pb, 2.5% Ag, 2% Sn. in question.
  • This has not only a relatively high ductility, but also a melting point that is sufficiently above the temperature to which the PTC heating element can heat up to a maximum (beyond its Curie temperature).
  • the edges of the two aluminum oxide plates 2 are connected to one another. It is also advantageous to produce the frame 12 by an injection molding process, specifically directly on the sandwich, wherein the space between the heating element 1 and the frame 12 visible in FIG. 2 can also be practically completely filled. However, it is advisable for the heating element 1 to have a space, even if it is only extremely small Leaving directional thermal expansion, the plastic is not sufficiently elastic anyway.
  • the already mentioned layers 4 made of a ductile solder not only serve as elastic cushion in principle known per se for another type of installation, namely with the application of pressure, but the solder layers 4 also have the important function of mechanical cohesion here.
  • the heating element 1 has on its plate sides 11 an all-over, solderable metallization made of e.g. Burn-in silver on and also the respective opposite surfaces of the aluminum oxide plates 2 are metallized at least up to the size of the surface of the heating element.
  • a metallization layer for the alumina plates can e.g. also made of stoving silver or also e.g. consist of copper, aluminum, zinc applied by plasma or flame spraying.
  • FIG. 2 is a section according to II-II of FIG. 1, so that only the connecting lug 22 can be seen in the illustration in FIG. This is guided through the frame 12 and electrically connected on the inside of the sandwich to the metallization of the one aluminum oxide plate 2.
  • this terminal lug 22 is soldered on.
  • the metallization of the aluminum oxide plate only extends beyond the edge of the heating element at the relevant point.
  • the connecting lug 21 which is not visible in FIG. 2, is arranged and with that in FIG. 2 and with the metallization of the lower aluminum oxide in FIG. 2 plate 2 electrically connected.
  • a thickness of between 0.5 and 2 mm is recommended for the aluminum oxide flat 2. Such a small thickness results in little thermal resistance with good thermal conductivity of the Al 2 O 3 .
  • This metallization 11 is preferably produced from stoving silver in the form of a double layer.
  • a first layer of baked-on silver In-Ga-Ag alloy No. E 4106, Demetron
  • silver stoving tincture No. E 4100, Demetron
  • This double layer of stoving silver is ideal for the further soldering process.
