Energy conversion device and energy conversion system of bituminous pavement

Abstract

The invention, which belongs to the technical field, discloses an energy conversion device and energy conversion system of a bituminous pavement. The bituminous pavement structure is formed by a pavement upper surface layer and a pavement middle and lower surface layer. The device comprises a first aluminum sheet arranged at the lower surface of the pavement upper surface layer, a second aluminum sheet arranged at the upper surface of the pavement middle and lower surface layer, a first emulsified asphalt film coating the lower surface of the first aluminum sheet, a second emulsified asphalt film coating the upper surface of the second aluminum sheet, a thermoelectric conversion element arranged between the first emulsified asphalt film and the second emulsified asphalt film, a positive electrode arranged on the first aluminum sheet, and a negative electrode arranged on the second aluminum sheet, wherein the upper surface and the lower surface of the thermoelectric conversion element are coated with a thermal-conducting silicone grease coating layer. On the premise that applicable durable and comfortable performances of the bituminous pavement are not affected, energy conversion, collection, storage, and utilization are realized by using the thermal energy accumulated in the bituminous pavement.

Description

technical field [0001] The invention relates to the technical field of energy conversion, in particular to an asphalt pavement energy conversion device and an energy conversion system. Background technique [0002] Due to its superior performance and driving comfort, asphalt pavement occupies a large proportion in high-grade highways and urban roads. Asphalt mixture is a typical heat-absorbing material, and its absorption rate of solar energy can reach 0.85-0.95. In most parts of our country, the highest temperature in summer can reach 35-40°C. Studies have shown that the maximum temperature of asphalt pavement is 25°C higher than the maximum temperature, and may reach 60-70°C. Therefore, under the continuous heat radiation of the sun, a large amount of heat is absorbed by the asphalt pavement and accumulated in the asphalt pavement, which makes the pavement temperature much higher than the air temperature. In the traditional pavement structure, this heat energy, which is ...

Problems solved by technology

In the traditional pavement structure, this heat energy, which is originally non-recyclable and thus wasted, can stimulate pavement diseases such as rutting and shifting, which not only seriously affects the service quality and service life of the pavement, but also affects traffic safety.
