The refrigerating chamber is a container with a top cover, with aluminum lining and external thermal insulation. The thermoelectric cooler is installed at the front of the container. The top of the container is covered with a tray and a lid. A connector on the front of the refrigerator compartment connects it to the console wiring harness.
The operation of the thermoelectric cooler is controlled by an on/off switch on the upper front panel of the container. The on/off switch is supplied with DC battery voltage through the CJB. When the cooler is turned on, the LED in the switch lights up.
The thermoelectric cooler is a solid state heat pump based on the Peltier effect. The Peltier effect lies in the fact that by passing direct current through junctions of dissimilar conductors, one of the junctions becomes cold, and the second one heats up. The potential difference at the junctions creates an electric field, when the circuit is closed, electric charges move against the electric field at one junction, which absorbs heat and - in the direction of the field at the other junction, which releases heat. In thermoelectric coolers, there are a large number of such junctions, which are connected in series and enclosed between ceramic plates, which are connected to a heat sink and are blown by a fan. The cold side of the thermoelectric cooler is in contact with the inner aluminum cladding, and the heat sink and fan are installed on the outside of the thermal insulation.
