Laird has recently developed a high heat flux density thermoelectric module (TEM) designed to achieve a higher heat pumping capacity than standard TEMs, called UltraTEC.
“The UltraTEC Series TEM has a heat pumping capacity up to 340 watts, which is ideal for larger cooling applications with limited surface area such as industrial lasers,” claimed Laird. It also has a “precise temperature control to within ± 0.01°C under steady state condition.”
Anders Kottenauer, Senior Vice President of Laird’s Engineered Thermal Systems unit, said, “The UltraTEC TEM delivers a more reliable cooling solution under continued use and when cycling at high powers,” and by “providing reliable solid state operation, the TEM cooling solutions does not produce noise or vibration and is available in multiple configurations.”
The UltraTEC TEM is “assembled with Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics, [and] designed for higher current and larger heat-pumping applications. With a Q Max @ temperature rating of 340.6W @ 25°C and heat pumping capacity up to 340 watts and an operating temperature up to 80 °C, the UltraTEC ensures the laser system will not overheat. For all UltraTEC™ Series modules, wire is stranded, 152 mm (6.0 in.) long or 200 mm (8.0 in.) and PVC insulated,” according to the company.
