Abstract

The invention discloses a generation system using the temperature difference between a city asphalt pavement and an underground water source pipeline. A water flow pipe network is distributed in the city asphalt pavement and is connected in parallel with the water source pipeline paved under the city asphalt pavement. And one part of a backflow water end of the water flow pipe network is wound on the water source pipeline. A temperature difference generation module is arranged between the water flow pipe network and the city asphalt pavement, and the temperature difference generation module is arranged on an area with a large temperature difference of the connection part of the water flow pipe network and the water source pipeline. According to the generation system disclosed by the invention, the pavement temperature and the environment temperature can be balanced by collecting the pavement temperature through the temperature difference generation modules, so that the durability and the using property of a pavement structure, which are influenced by the temperature, are improved. Meanwhile, temperature difference generation has the advantages of reliable property, no pollution, no noise and sustainable use. Generated electric energy further can be used as supplements of power utilization of municipal works, such as roadway illumination, and traffic lights.

Description

technical field [0001] The invention relates to a pavement power generation technology, in particular to a power generation system utilizing the temperature difference between urban asphalt pavement and underground water source pipelines. Background technique [0002] Thermoelectric power generation technology is a new power generation technology that uses the Seebeck effect to directly convert heat energy into electrical energy. In recent years, with the continuous research and development of high-performance thermoelectric materials, thermoelectric power generation technology has been continuously applied and promoted in various fields, such as radioisotope thermoelectric generators on spacecraft, automobile exhaust waste heat recovery systems, and utilization of ocean thermoelectric energy. At present, this technology is only applied in specific high-end technical fields, and there is no application precedent in the field of road heat utilization. Contents of the invent...
