The system introduced here is Air to Cold plate type thermoelectric cooling/heating unit with 400 watts cooling power where we use heat sink with fans for heat dissipating of thermoelectric modules to cool or heat up the cold plate. The unit is designed for cooling or heating cold plate purpose. It can cool down the clod plate to -20 ?C and also can be used to heat up to 120 ?C when the input polarity is revised at the 20 ?C ambience. Built up with our high performance TEHC series thermoelectric cooling modules, the unit demonstrates superior performance.
The 400 W thermoelectric cooling/heating unit runs on 24 VDC with 22 A current drawn. When the red wire is connected to positive and black to negative it is in cooling mode, and if the polarity is reversed, then in heating mode.
