Problems solved by technology

These technologies are difficult to ensure that piezoelectric crystals will not be damaged during road construction, and are not easy to be reused. At the same time, using the power generation surface that cuts the magnetic induction line will cause a certain degree of damage to the road surface when the power generation rod is laid, reducing the performance of the road surface.
[0004] The above research results are mostly aimed at the load on the asphalt pavement, ignoring the thermal energy storage advantages of asphalt concrete. As a heat-absorbing material, asphalt can absorb more heat than cement pavement, soil, and vegetation. Small, less evaporation heat consumption, fast h

The thermoelectric energy converter comprises a P component, a N component and electrodes arranged on the end faces of the P component and the N component, wherein the P component is prepared from pyrite powder; the thermoelectricity coefficient of the pyrite powder is a positive value; the N component is made of galena powder; the thermoelectricity coefficient of galena powder is a negative value. The invention also provides a power generation pavement structure. The thermoelectric energy converter provided by the invention is high in thermoelectricity conversion rate; the power generation pavement structure provided by the invention can increase the temperature reduction speed of the pavement, can improve the pavement performance, and can convert the thermal energy of the pavement into electricity energy, thus releasing the existing energy source problem.

Description

technical field [0001] The invention belongs to the field of roads, and in particular relates to a thermoelectric transducer and a power generation surface structure based on the thermoelectric transducer. Background technique [0002] The existing environmental and energy problems are becoming more and more serious, and the energy shortage has been highly concerned by people. In order to solve this problem, people pay a lot of attention to the development of asphalt pavement with power generation function. [0003] At present, many achievements have been made in the research on the power generation surface, but usually the piezoelectric crystal, liquid deformable body, etc. are buried in the road surface, or the magnetic induction line is cut. These technologies are difficult to ensure that piezoelectric crystals will not be damaged during road construction, and are not easy to be reused. At the same time, using the power generation surface that cuts the magnetic induction ...
