Heat transfer to refrigerate or heat uses a thermoelectric semiconductor structure including a P-type composite of dices of semiconductor material alloyed with P-type material forming spaced collector regions at junctions with a P-type conductive material for flux of electrical current and a N-type composite of dices of semiconductor material alloyed with N-type material forming spaced collector regions at junctions with a N-type conductive material for flux of electrical current. The thickness of each the dices is sufficient to form a PN junction. Electrically conductive buss bars form an electrical circuit between the dices of N-type conductivity and the dices of P-type conductivity. An electrically conductive buss bar forms an electrical circuit connection between the dices of N-type conductivity and the dices of P-type conductivity. An electrical potential is applied by terminals between the P-type composite and the N-type composite to induce a flux of heat concurrent with the flux of electrical current.
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.
