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.
The company was founded in 1947 in Katy and is known for its blue and white coolers. [citation needed] Igloo's product line includes a wide range of coolers and ice chests for various uses, from small personal coolers to large commercial coolers, as well as beverage dispensers, marine coolers, and accessories.
II-VI Marlow designs and manufactures semiconductor-based thermoelectric coolers and subsystems, [10] which provide cooling, heating, temperature stabilization, power generation, and energy harvesting functions. [1] Its products are used for infrared sensors, fibre-optic guidance systems, thermal reference sources, refrigerators, and chillers ...

Thermoelectric generators function like heat engines, but are less bulky and have no moving parts. However, TEGs are typically more expensive and less efficient. [ 2 ] When the same principle is used in reverse to create a heat gradient from an electric current, it is called a thermoelectric (or Peltier) cooler .
The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...
