Thermoelectric energy harvesters

1 May 2013 Power Electronics / Power Management

Nextreme Thermal Solutions announced a new series of thin-film thermoelectric power generators that offer a robust mechanical design and ease of integration with common sources of thermal energy.

The eTEG PG8000 series harvests waste heat from thermal sources, converting it into electricity for a variety of self-powered applications in the wireless sensor, automotive, aerospace, industrial and medical device markets.

The product family includes five new modules that can produce between 2,7 mW and 21,6 mW of output power and open circuit voltages of 0,17 V to 1,35 V at a temperature differential (T) of only 10 K. At 50 K T, they can produce 65 mW to 520 mW of power and open circuit voltages of 0,85 V to 6,8 V. The modules can be configured electrically in series to produce higher output voltage.

The devices can provide electricity to a load directly when a constant heat source is available or can be used in combination with batteries when the heat source is variable. The eTEG PG8000 series operates with moderate heat flux density that matches the heat flux found in common sources of thermal energy such as piping and industrial manufacturing processes. Heat fluxes in this range simplify integration with heatsinks that are necessary to maintain constant heat flow.

The new series features a high mechanical strength seal ring made from Cirlex polyimide film that provides mechanical isolation across the thermoelectric device, virtually eliminating vertical force and sheer issues. The seal ring also serves as a barrier to moisture and other contaminants that could affect the performance of the module.
