Abstract:
1. A multistage composite thermoelectric module including the combination of multistage P-type composites each comprised of two dices of P-type semiconductor material joined by a P-type conductive material to induce flux of electrical current concurrent with a flux of heat, one dice of P-type semiconductor of each of two P-composites being superimposed and having a common heat flux origin and the remaining one dice of the P-type semiconductor of each of said two P-type composites having laterally spaced heat flux site for increasing the temperature differential between the refrigeration temperature and heat sink temperature increasing the thermal capacity for removing heat from the refrigeration area, and multistage N-type composites each comprised of two dices of N-type semiconductor material joined by a N-type conductive material to induce flux of electrical current concurrent with a flux of heat, one dice of N-type semiconductor of each of two N-composites being superimposed and having a common heat flux origin and the remaining one dice of the N-type semiconductor of each of said two N-type composites having laterally spaced heat flux site for increasing the temperature differential between the refrigeration temperature and heat sink temperature increasing the thermal capacity for removing heat from the refrigeration area.
