Tripolar conductor type thermoelectric conversion device

The utility model discloses a three-pole conductor type thermoelectric conversion device, which is characterized in that a three-pole conductor structure consisting of a P-type semiconductor plate, an N-type semiconductor plate and a metal material ring is placed on another same three-pole conductor structure, so that the P-type semiconductor plate is in contact with the N-type semiconductor plate to form a loop with an electricity storage device; when the two same three-pole conductors are in contact, electron or hole diffusion occurs at the contact position of the two same three-pole conductors, current flows in the wires, and electric energy can be stored in the electricity storage device. When the USB output interface is connected with an electric appliance, the electric energy in the electricity storage device can be supplied to the electric appliance for use. The insulator housing isolates external contact to a certain extent, reduces the oxidation possibility, and improves the hot spot conversion effic
