The working principle of the TEC cooler:

  • Thermoelectric modules are solid-state heat pumps that operate on the Peltier effect.
  • A thermoelectric module consists of an arrangement of p- and n- type semiconductor elements that are heavily doped with electrical carriers.
  • The elements are arranged into an array that is electrically connected in series but thermally connected in parallel.
  • This array is affixed to two ceramic substrates, on side cold for heat absorption and the other side hot, for heat dissipation.
  • When a DC power source is supplied, the heat is absorbed on the cold side of the n- and p-type elements and the heat is released on the hot side of the thermoelectric element.
  • The heat pumping capacity of a module is proportional to the current and is dependent on the element geometry, number of couples and material properties.

Features:

  • A TEC cooler consists of a double heat sink with a hot and cold side, p- and n- elements, two (2) fans and temperature sensors all controlled via a Peltier controller.
  • The internal and external interface of the TEC unit is rated at IP56, which is sufficient to protect the unit from moistures, dust and rain.
  • Build to withstand sever weather conditions (-40 degrees to +60 degrees).
  • Precise temperature control via PWM controller +/- 0.5 degrees Celsius.
  • Thermoelectric (Peltier effect) cooling method, no compressor, no refrigerant.
  • Extremely reliable with an approximate life span of 8 to 10 years.
  • Very low maintenance.
