Definitions

  • the temperature distribution between the two heating sources B1 and B2 is based solely on the thermal conductivity of the selected material. It also prevents the desired temperature distribution if control points C3, C4 are also relocated to the block area between the heating sources B1, B2. Even if additional heating sources B3, B4 are installed in the block area, as est. B. from the patent DE-C-537125, but without sensor-controlled control, is known per se, the result is unsatisfactory.
  • the invention proposes a heating plate as specified in claim 1 and shown in FIG. 2.
  • the heating surface is divided into the smallest possible segments S 1 , S 2 , ..., S " .
  • Each individual segment (FIG. 3) has a heating source H and a heat sensor W as a sensor, which are arranged in a mass M.
  • the shape of a segment can be chosen in such a way that it meets the geometrical requirements for any heating surface, Fig. Shows an exemplary arrangement of these segments to an example rectangular heating surface.
  • each segment can assume a defined target temperature that is independent of other segments. Since the flow of heat from a warmer to a colder segment has to be prevented, a thermally conductive material L is installed between the segments, as shown in FIG. 6, so that the inevitably penetrated heat is dissipated to the surroundings.
  • the heating plate consists of a sufficiently large number of segments of the type described. Temperature curves can be realized on this heating plate in accordance with any curve shape. Because of its division (quantization) into separate segments, the heating plate according to the invention can be referred to as a «digital heating plate.
  • the invention differs from this by the additionally introduced heat-conducting material L for dissipating the inevitably penetrated heat to the surroundings.
  • All segments can be controlled centrally. This is possible because each segment forms a completely self-contained unit. A temperature fault can be corrected immediately because the heating power of each segment represents a multiple of the nominal power.
  • connection between the heating element and the segment, or mass M is designed to be as lossless as possible. The same applies to the connection to the sensor.
  • the target-actual deviation of each segment (+/- 0.3 degrees Celsius) applies to the «digital» heating plate for the entire area; the temperature reproducibility is accordingly high.
  • each individual segment can be regulated very quickly - due to its correspondingly much lower heat capacity. Derived from this, water cooling is completely eliminated.

2. Plaque chauffante, selon la revendication 1, caractérisée par le fait que les segments (S1 à Sn) forment une surface plane.
3. Plaque chauffante, selon les revendications 1 ou 2, caractérisée par le fait qu'un matériau (G) se trouve sur la surface formée par les segments (S1 à Sn) afin de :
a) réduire sensiblement des écarts temporels de la température réelle de chaque segment (fig.4) et
b) d'exercer un effet intégrant sur plusieurs segments (fig. 5).
4. Plaque chauffante, selon la revendication 1 ou bien la revendication 2, avec référence à la revendication 1, caractérisée par le fait que les segments (S1 à Sn) forment des surfaces courbes, par exemple des coupes.
