Koolatron 12-Volt Cooler TechnicalTechnical Information on 12-Volt CoolersRefrigeration is the process of pumping heat energy out of an insulated chamber in order to reduce the temperature of the chamber below that of the surrounding air. Thermoelectric refrigeration uses a principle called the "PELTIER" effect to pump heat electronically. The Peltier effect is named after a Jean Peltier, a French scientist who discovered it in 1834. He noted that when an electrical current is applied across the junction of two dissimilar metals, heat is removed from one of the metals and transferred to the other. This is the basis of thermoelectric refrigeration. Thermoelectric modules are constructed from a series of tiny metal cubes of dissimilar exotic metals which are physically bonded together and connected electrically. When electrical current passes through the cube The Koolatron's internal aluminum cold plate fins absorb heat from the contents, (food and beverages), and the thermoelectric modules transfer it to heat dissipating fins under the control panel. Here, a small fan helps to disperse the heat into the air. The system is Totally Environmentally Friendly and contains no hazardous gases, nor pipes nor coils and no compressor. The only moving part is the small 12-volt fan. Thermoelectric modules are too expensive for normal domestic and commercial applications which run only on regular household current. They are ideally suited to recreational applications because they are lightweight, compact, insensitive to motion or tilting, have no moving parts, and can operate directly from 12-volt batteries. A 12-Volt Cooler is much better than a regular Cooler full of Ice. Food and beverages are kept cold and dry. No space is wasted for ice (unless of course you want ice, in which case we can help to preserve it 3 or 4 times longer than a plain cooler. Advantages of Thermoelectric Refrigeration:
