What exactly is thermoelectric cooling?
According to me, Thermoelectric coolers or cooling is a peltier module that can generate both heating or cooling thermal power when supplying an electric DC current at different directions. It can generate both heating or cooling thermal power when passing an electric DC current at different directions.
Many smaller wine coolers employ thermoelectric cooling instead of utilizing a traditional compressor and refrigerant. A thermoelectric wine cooler will contain what is referred to as a cooling node which is simply a ceramic tile that has electrical current passed through it. As the electrical current is passed through the cooling node the outside of the tile will heat up and the other side (the side facing into the cooler) will cool down. Typically, a thermoelectric wine cooler will contain small fans inside the unit which help to evenly distribute the cool temperatures being created by the node throughout the interior of the unit. Due to the lack of a compressor, thermoelectric coolers will produce fewer vibrations which in turn will equal fewer disturbances of the sediments within the wine bottles. Please keep in mind that thermoelectric wine coolers are not completely silent as the internal fans needed to distribute the cold air within the cooler will produce some noise. Overall, t
