FOR COOLING AND TEMPERATURE CONTROL

eTEC™ HV56

  • Designed to address electronics cooling applications with larger heat pumping requirements.
  • At 85°C, pumps a maximum of 6 watts of heat with a maximum voltage of 10.89V and a ΔT of up to 60°C in a footprint of only 11 mm².
  • At 25°C, pumps a maximum of 4.8 watts with a maximum voltage of 8.8V and a ΔT of up to 50°C.
  • Ideal for optoelectronics applications with high heat-flux requirements, particularly semiconductor optical amplifiers (SOA), laser diodes and LEDs
  • At 85°C, pumps a maximum of 4.5 watts of heat with a maximum voltage of 7.7V and a ΔT of up to 60°C in a footprint of only 6 mm².
  • At 25°C, pumps a maximum of 3.7 watts with a maximum voltage of 5.98V and a ΔT of up to 50°C

OptoCooler™ HV14

  • First in a new class of RoHS-compliant high voltage / low current thermoelectric coolers optimized for standard circuitry and power requirements.
  • Operates at a maximum voltage of 2.9V and can pump a maximum of 1.7 watts of heat at 85°C in a footprint of only 2.8 mm²
  • Miniature heat pumps for rapid cooling and heating
  • Cool hot spots for improved performance and increased reliability for high-performance CMOS ICs, RF components, HB-LEDs, laser diodes and other optoelectronic chips
  • Performs precision thermal management of temperature sensitive devices, such as photonic ICs, DNA analysis chips, and IC test systems
  • Available with or without wires attached

FOR POWER GENERATION

  • Provides a constant voltage output of 3.3, 4.1 or 5.0 Vdc to electrical loads of 15kΩ or higher.
  • Produces up to 1mW of electrical power.
  • Operates at temperature differentials as low as 15-20K relative to ambient. Larger temperature differences can generate significantly more power.
  • Features on-board energy storage.
  • Eliminates power source fluctuations caused by variable heat sources.
  • Produces regulated 3.3VdC with a peak power of up to 200 mW. Larger temperature differences can generate significantly more power.
  • Operates at temperature differentials as low as 10 degrees K in a footprint of only 11mm².
  • At 10K ΔT, produces 1.5mW of output power and an open circuit voltage of 0.25V.
  • At 50K ∆T, produces 36.5mW of power and an open circuit voltage of 1.25V.
  • Can be configured electrically in series to produce higher voltage and power outputs.
  • Ideal for energy harvesting for self-powered distributed sensors and sensor networks.
  • At 10K ΔT, produces 1.0mW of output power and an open circuit voltage of 170mV.
  • At 50K ∆T, produces 24mW of power and an open circuit voltage of 850mV.
  • Can be configured electrically in series to produce higher voltage and power outputs.
  • Demonstrated output power levels of >16mW at ΔT of 70°C and >45mW at ΔT of 120°C
  • Measures just 1.8mm x 1.5mm.
  • Has corresponding output power densities of ~ 0.6 and 1.6W/cm².
  • Can be arranged in custom arrays to match power generation requirements
  • An easy-to-use, self-contained evaluation kit for conducting desktop demonstrations of the eTEG device.
  • Kit consists of a HV56 eTEG power generator, a thick film heater, heat sink / fan assembly and two type K thermocouples

Nextreme’s product portfolio includes modules that range in resistance from 50mΩ to 3Ω with corresponding Imax currents of 0.8A through 4A. The optimal drive current for these modules in an application is likely to be in the 0.2A to 1.5A range. Several off-the-shelf Thermoelectric Cooler Controllers or Temperature Controllers are available to drive and control Nextreme modules.

Integrated temperature sensing of the cold-side of thin-film thermoelectric coolers is a challenge due to small surface area of the coolers’ top header. Micro-scale thermistors can be mounted either directly onto the top surface of the header or on the side of the top header to enable closed-loop temperature control.
