Definitions

  • the invention relates to a method for operating a Peltier element.
  • a Peltier element is an electrothermal transducer which generates a temperature difference based on the Peltier effect at current flow.
  • a common abbreviation for Peltier elements and Peltier coolers is TEC (English: thermoelectric cooler).
  • the inverse of the Peltier effect is the Seebeck effect.
  • Peltier elements have various advantages, such as no mechanical moving parts or gases or liquids, no refrigerant and by reversing the direction of both cooling and heating is possible.
  • a disadvantage, however, is the low efficiency.
  • the invention is based, to increase the efficiency of a Peltier element the task.
  • the object When operating a Peltier element as an electrothermal converter, the object is achieved according to the invention by a method in which the Peltier element is acted upon by pulsed electrical energy.
  • the Peltier element is preferably supplied with a rectangular direct current.
  • the object When operating a Peltier element as a thermoelectric generator, the object is achieved according to the invention by a method in which the electrical energy is extracted in pulsed form.
  • Fig. 1 shows schematically a Peltier element and an electrical energy source for operating the Peltier element as an electrothermal transducer
  • Fig. 2 shows a current diagram
  • Fig. 3 shows schematically a Peltier element and an electronic circuit for operating the Peltier element as a thermoelectric generator.
  • Fig. 1 shows schematically a Peltier element 1 and an electrical energy source 2, the are connected to each other in a circuit 3. The direction of the current flowing in the circuit is indicated by arrows.
  • the invention proposes to use and operate the Peltier element 1 as an electrothermal transducer, i. as a cooling element and / or heating element to make the supply of electrical energy pulsed, instead of supplying a direct current as usual.
  • the energy source 2 is therefore set up to apply a pulsed direct current to the Peltier element 1.
  • the pulsed direct current is preferably rectangular with steep edges as possible.
  • FIG. 2 shows such a pulsed rectangular DC current I (t) as a function of time t.
  • the optimal duty cycle i. the ratio ⁇ / T of pulse duration ⁇ to period T is dependent on the materials used for the Peltier element 1.
  • the invention can be, as shown in Fig. 3, vice versa also apply when the Peltier element 1 is used as a thermoelectric generator to from the prevailing between the two sides of the Peltier element 1 temperature difference according to the Seebeck effect an electric current to create.
  • the electrical energy is extracted in pulsed form, for example by means of a corresponding electronic circuit 4. Again, the energy is preferably removed by means of rectangular pulses.
