Nextreme Thermal Solutions has released an easy-to-use, self-contained platform for conducting desktop demonstrations of its thermoelectric cooling technology. The eTEC Thermoelectric Cooling Evaluation Kit contains a single UPF40 thermoelectric module, an air-tight cooling environment and electrical connections to make precise temperature measurements of the thin-film thermoelectric device.
The UPF40 module can be embedded in a laser diode package to maintain proper operating conditions while improving output levels, reliability and longevity of the laser. The laser can be mounted directly on the UPF40 module, providing the ability to precisely cool the laser without the need to cool the entire package, which reduces the overall power budget of the device. Higher power lasers can be delivered in smaller and less costly packages.
The module can pump a heat density of up to 72W/cm² at 25°C, and as a result, it can move a maximum of 3.7W of heat with an active footprint of only 5.1mm².
