Tunnel type waste heat recovery semiconductor power generation method and device by temperature difference

Abstract

The invention provides a tunnel-typed residual-heat recovery semiconductor temperature difference generation method and a device. The generation method is characterized in that a movable heat source which emits residual heat runs pass a tunnel-typed heat collector which receives the heat emitted by the movable heat source and transmits the collected heat to a heat surface of a semiconductor temperature difference generation module; a radiator is arranged at one side of a cooling surface of the semiconductor temperature difference generation module; the cooling surface is cooled to a temperature much lower than that of the heat surface by the radiator, thus generating a large temperature difference at two end surfaces of the semiconductor temperature difference generation module; the semiconductor temperature difference generation module directly converts the temperature difference into the electric potential difference which is used as a power supply after being converted by a stabilizer circuit and AC / DC. The device of the invention comprises the semiconductor temperature difference generation module, the tunnel-typed heat collector, and a radiator; the method and the device of the invention have the advantages that the recovered residual heat energy can be directly converted into electric power, the generation process has no noise, no abrasion and no medium leakage, furthermore, the generator has the small volume, light weight, convenient movement, maintenance-free and long service life, etc.

Description

technical field [0001] The present invention relates to a tunnel-type waste heat recovery semiconductor thermoelectric power generation method and device, which is a new energy development and application technical field with thermoelectric conversion as the core technology and industrial waste heat recovery power generation as the goal. Background technique [0002] my country is a big energy-consuming country, and the amount of industrial waste heat is huge. Whether it is solid, gaseous, or liquid, there is a large amount of industrial waste heat to be recovered. Therefore, recycling these waste heat in the production process of enterprises has great social and economic benefits for energy saving and efficiency enhancement. . At present, most of the waste heat recovery devices commonly used in my country are only for gaseous and liquid waste heat, and there is no recovery for solid waste heat (except CDQ). The present invention is aimed at the recovery and utilization of t...
