Nextreme Develops New OptoCooler Thermoelectric Module for Photonics Cooling
Nextreme Thermal Solutions introduced the OptoCooler™ HV37 module, the next product in its high-voltage (HV) line of thin-film thermoelectric coolers (TECs) designed to address photonics cooling applications with larger heat pumping requirements. At 85°C, the OptoCooler HV37 can pump 4.5 watts or 107W/cm2 of heat in footprint of only 6 mm2. The device is only 0.6mm high, which the company says makes it one of the thinnest heat-pumping TECs in the photonics market today.
At 85°C, the OptoCooler HV37 can create a temperature differential (deltaT) of up to 60°C between its hot and cold sides, and operates at a maximum voltage of 7.7V, making it compatible with commonly found board-level currents and voltages. At 25°C, the device can create a deltaT of up to 50°C with a maximum voltage of 5.9V.
The OptoCooler HV37 is RoHS-compliant and is manufactured using gold-tin (AuSn) solder, which enables assembly temperatures as high as 320°C. These assembly temperatures make the HV37 module compatible with industry standard processes for packaging photonics devices that require tight tolerances.
"Thermoelectric coolers made from thin-films are smaller and thinner than conventional TECs and can be embedded in the smallest of packages," said Dave Koester, Vice President of Engineering at Nextreme. "In addition to its high-heat pumping capability, the OptoCooler HV37 has a low mass, which enables a more rapid thermal response to changing temperatures for precise temperature control."
The OptoCooler HV37 module is available with an 8 to 10 week delivery lead time. Pricing is available upon request.
