Producton of thermoelectric microcoolers using bismuth telluride nanopowder for optic-, micro-, and nanoelectronics

RMT Ltd is manufacturing thermoelectric micromodules based on the Peltier effect. The modules provide cooling, local heat dissipation, and heat regime maintenance for a variety of instruments and devices: semiconducting and other lasers, powerful LEDs, highly sensitive photo detectors, ICs, microprocessors, and biomedical instruments. These miniature thermoelectric coolers, the specialty of project initiator RMT, are integrated into microelectric units, thereby providing the most efficient cooling—the closer the cooling element is to the heat source, the more effectively the unit works.

The project opened a pilot production base in May 2011 in Moscow. In November of that year, it began operations at its main manufacturing facility in the Ankudinovka Technopark in Nizhny Novogorod. RMT Ltd is an outstanding example of how a scientific advance made by Russian specialists is commercialized and its production is later expanded to meet demand from foreign companies for an innovative product. RMT exports 80 percent of its output to the United States, Canada, Japan, Europe, and Southeast Asia.

The thermoelectric modules use the Peltier effect which results in heat consumption at the junction of two different conductors. These modules are able to cool the medium to small power electronic devices for a tens of degrees. The key role in good cooling efficiency plays the thermoelectric materials of which the module is made of.

RMT uses the hot extrusion technique for producing thermoelectric material from original Pb-Vi-Te nanopowder. This allos to reach additional 15–20°С in cooling for single-stage modules. The size of material particles is about 5–20 nm.

Themoelectric elementsThe RMT's products line includes ultra-thin (less than 1 millimeter) micromodules which are used for cooling optoelectronics, microelectronics, and, especially, telecommunications (the photo shows a cooled cage for IR-laser diode for telecom equipment). The modules provide cooling temperature difference—from 70°С to 130°С in the heat flow diapason from 40 W to 100 W per cubic cm, for single- and multi-stage modules.
