Title:
SOLAR THERMAL POWER GENERATOR
Document Type and Number:
Japanese Patent JP2569428
Kind Code:
B2
Abstract:
PURPOSE: To generate an electric field in thermoelectric conversion part member so as to be vertial to both temperature gradient and magnetic field, and lead out a voltage from both end portions of the electric field, by applying a magnetic field in the direction vertical to the temperature gradient by a magnetic field generating means.
CONSTITUTION: In a power generating pipe 10, a vacuum pipe 4 is installed so as to surround a ring-shaped permanent magnet 2. A thermoelectric conversion part member 1 is arranged in the gap between poles of the permanent magnet 2. Solar light 6 penetrates a window part 5 and is condensed on the outer peripheral end of the part member 1, which is heated by the solar light. Hence, in the thermoelectric conversion part member 1, temperature gradient is formed in the direction from the outer peripheral end heated at a high temperature to the inner peripheral end cooled by a cooling pipe 3. Between the window part 5 and the magnetic poles of the permanent magnet 2, mutually facing reflecting plates 19 are interposed, thereby increasing the efficiency of light condensation and heat condensation. Solar thermal power generation is performed by' thermoelectric conversion using Nernst effect, so that miniaturization is realized while ensuring high conversion efficiency.
