Thin-film miniature thermoelectric devices offer 55°C of cooling performance at 25°C ambient
The 55°C temperature milestone, known as the DeltaTmax, reflects the ability of the thermoelectric device to pump heat efficiently. This new level of performance translates to improved cooling efficiency, lower input power requirements, and greater opportunities for solving thermal issues in electronics, photonics and avionic applications. The Nextreme eTEC HV14 is one of the world’s smallest thermoelectric modules with a footprint of only 3mm². The thin-film module can pump up to a maximum power density (Qmax/area) of 120 W/cm² in comparison to less than 10 W/cm² for the bulk TEC. The response time of the eTEC HV14 is on the order of milliseconds compared to seconds for bulk devices. These devices are only 0.6mm high, making them the thinnest, highest heat pumping thermoelectric coolers on the market today. The miniature size and heat pumping capability make thin-film thermoelectric modules ideal for cooling laser diodes, photodiodes, LEDs, infrared (IR) sensors, pump lasers, crystal oscillators and optical transceivers.
