Nextreme’s OptoCooler HV14 breaks temperature barrier

Nextreme Thermal Solutions of Durham, NC, USA says that its OptoCooler HV14 is the first high voltage, low current thin-film thermoelectric cooler (TEC) targeted at laser diode cooling for the telecommunications market to achieve a 60°C temperature difference between its cold and hot sides. This temperature difference, known as the ΔT, reflects the ability of the device to pump heat efficiently.

The OptoCooler HV14 thermoelectric cooler is the first module in a new class of high voltage and high heat pumping thermoelectric coolers that operate at low currents and are optimized for standard circuitry and power requirements, says the firm. It can pump up to 1.5W of heat at 85°C and operates at a maximum voltage of 2.7 with a maximum current of around 1A. With a footprint of 2.8mm², the module is suited for the cooling and temperature control of optoelectronic devices such as laser diodes for transmission modules and photodiodes for sensing, adds Nextreme.

According to Nextreme, the micro-size and power-pumping capabilities of the HV14 module mean that manufacturers of LEDs and other semiconductor chips can now integrate cooling and temperature control functionality directly into the package during assembly, resulting in a high-volume, lower cost thermal management solution.

"Breaking the 60°C ΔT barrier raises the bar in terms of improved efficiencies and lower operating costs," said Dave Koester, vice president of engineering at Nextreme. "Devices with higher ΔTs require less operating power to achieve the desired cooling effect, which is significant for achieving a greener world."
