Thermoelectric unit for converting heat into electric current in electrically-driven motor car, has thermoelectric elements arranged between differently oriented outer sides of inner and outer fluid guide elements

摘要

The thermoelectric unit (100) has an inner fluid guide element (110) in which fluid channels (120) are arranged. Each of the fluid channels is arranged in two outer fluid guide elements (140). Two thermoelectric elements (130) i.e. Peltier elements, are arranged between an outer side of the inner fluid guide element and a differently oriented outer side of the outer fluid guide elements. The inner and outer fluid guide elements have material blocks i.e. metal blocks in which apertures or holes are formed as the fluid channels.
