Abstract

The invention discloses a thermoelectric conversion device with metal tubes serving as an inner electrode and an outer electrode. The thermoelectric conversion device comprises the inner electrode, the outer electrode and a thermoelectric conversion material arranged between the inner electrode and the outer electrode, wherein the inner electrode is one of the metal tubes, the outer electrode is the other metal tube, the thermoelectric conversion material is Ce (FexZryPbz)13, the range of x is from 0.70 to 0.95, the range of y is from 0.05 to 1- x, and the range of z is from 0.005 to 0.5. The thermoelectric conversion device solves the problems that in the prior art, the conversion rate of the thermoelectric conversion technology is low and the practical application effect of the thermoelectric conversion technology is poor, and is high in thermoelectric conversion efficiency.

Description

technical field [0001] The invention relates to a thermoelectric conversion device. Background technique [0002] The thermoelectric effect is a phenomenon in which a current can be induced when a substance is heated, and the current intensity increases with the increase of heat. Substances that can induce electric current when heated are called thermoelectric effect materials, also called thermoelectric conversion materials. The two metal materials are used as two poles, and the two metal materials are connected by a thermoelectric conversion material in the middle to form a thermoelectric conversion device. [0003] The thermoelectric conversion device is a unidirectional heat conduction structure, which first heats a metal electrode, and then conducts heat to another metal electrode through the thermoelectric conversion material by the heated metal. Due to the unidirectional heat conduction structure, the conversion of tiny hot particles into electrons produces a contin...
