Thermoelectric Condenser

The XZ-LNQ-03 semiconductor single-channel condenser operates on the principle of semiconductor refrigeration, utilizing the thermoelectric effect of semiconductors to generate cooling. Two different metals are connected by a conductor. When a direct current is applied, one junction decreases in temperature while the other junction increases. Reversing the power supply reverses the temperature change at the junctions. When power is applied, electron-hole pairs are generated near the upper junction, reducing its internal energy and temperature, absorbing heat from the surroundings — this is called the cold side. At the other junction, electron-hole pairs recombine, increasing internal energy and temperature, releasing heat to the environment — this is called the hot side. The temperature difference and cooling capacity produced by a single pair of semiconductor thermoelectric elements are very small. Practical semiconductor refrigerators consist of many thermoelectric elements combined in parallel and series, also known as a thermoelectric stack. A single-stage thermoelectric stack can achieve a temperature difference of approximately 60°C, meaning the cold side temperature can reach -10 to -20°C.
