  2. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    v. t. e. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...

  3. Thermoelectric cooling - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_cooling

    Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

  4. Jean Charles Athanase Peltier - Wikipedia

    en.wikipedia.org/wiki/Jean_Charles_Athanase_Peltier

    The Peltier effect is the presence of heating or cooling at an electrified junction of two different conductors (1834). [7] His great experimental discovery was the heating or cooling of the junctions in a heterogeneous circuit of metals according to the direction in which an electric current is made to pass round the circuit.

  5. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have ...

  6. Cloud chamber - Wikipedia

    en.wikipedia.org/wiki/Cloud_chamber

    Scientists. v. t. e. Radium 226 source in a cloud chamber. A cloud chamber, also known as a Wilson chamber, is a particle detector used for visualizing the passage of ionizing radiation. A cloud chamber consists of a sealed environment containing a supersaturated vapor of water or alcohol. An energetic charged particle (for example, an alpha or ...

  7. Joule heating - Wikipedia

    en.wikipedia.org/wiki/Joule_heating

    Joule heating (also known as resistive, resistance, or Ohmic heating) is the process by which the passage of an electric current through a conductor produces heat.. Joule's first law (also just Joule's law), also known in countries of the former USSR as the Joule–Lenz law, [1] states that the power of heating generated by an electrical conductor equals the product of its resistance and the ...

  8. Thermoelectric battery - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_battery

    Thermoelectric battery. A thermoelectric battery stores energy when charged by converting heat into chemical energy and produces electricity when discharged. Such systems potentially offer an alternative means of disposing of waste heat from plants that burn fossil fuels and/or nuclear energy. [1]

  9. Thermoelectric acclimatization - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_acclimatization

    Thermoelectric acclimatization depends on the possibility of a Peltier cell of absorbing heat on one side and rejecting heat on the other side. [1] Consequently, it is possible to use them for heating [2] on one side and cooling on the other [3] and as a temperature control system. [4] Figure 1.
