Thermoelectric Power Generator

Nextreme Thermal Solutions (Durham, NC) offers the eTEG™ HV37 thermoelectric power generator, the next entry in the high-voltage (HV) series of clean energy generators based on thin-film thermoelectrics. The eTEG HV37 converts waste heat into electrical energy for a variety of self-powered applications.

The eTEG HV37 is capable of producing 1.0mW of output power and an open circuit voltage of 170mV at a 10K ΔT in a footprint of only 6mm². At 50K ∆T, the HV37 produces 24mW of power and an open circuit voltage of 850mV. The module is extremely thin: only 0.6mm high, and can be configured electrically in series to produce higher voltage and power outputs.

Nextreme’s eTEG devices generate electricity via the Seebeck Effect where a voltage is produced from the temperature differential produced by heat flow through the device. The new module is RoHS-compliant and manufactured using eutectic gold-tin (AuSn) solder, which enables assembly temperatures as high as 320°C.
