Highly Effective Thermoelectric Coolers

Multilayer thermoelectric coolers offer a great promise in the refrigeration field. These solid state coolers have great advantages over the conventional Peltier coolers and compressed based units, these include compact size, high cooling rates, high power densities, no working fluid, lightweight, and cost effectivness. In Phase I, Sigma developed the technique for making multilayer Peltier. In Phase II, Sigma proposes to scale up the Phase I process. Sigma proposes here a cost effective, vacuum based, solvent free batch process to manufacture the new generation of multilayer coolers in one single pass. An inline monitoring system assures a high reliability. At the end of Phase II, Sigma will produce hundred of parts for field testing. Sigma will collaborate with major refrigeration companies to take the product to the market in record times.
