THERMOELECTRIC GENERATOR PIPE AND METHOD FOR PRODUCING THE GENERATOR PIPE

摘要

A thermoelectric generator pipe for producing electrical energy, surrounds a heat source or a heat sink. The generator pipe is formed by a helix structure having an inner and outer conductor strips that are electrically conductive. The conductor strips have substantially the same width and are wound with the same pitch. Between the inner and outer conductor strips, first and second intermediate axial spaces are formed, which are each arranged between one edge of the inner conductor strip and the edge of the immediately adjacent outer conductor strip. The intermediate spaces are formed as a double helix. First and second layers are arranged respectively in the first and second intermediate spaces. The first and second layers are formed respectively from n-doped and p-doped, thermoelectric and percolating particles. The generator pipe is slit subdivided in the axial direction to produce sections that form thermoelectric elements connected in series.
