Intelligent thermal conductive pavement energy system

Abstract

This invention relates to a smart thermally conductive pavement energy system, comprising a thermally conductive layer, a closed-loop thermally conductive pipeline, a heat conversion module, and a sensing and control unit. The smart thermally conductive pavement energy system absorbs and dissipates surface heat to reduce pavement temperature, and converts the heat energy into electrical energy through a thermoelectric (TEG) module or an organic Rankine cycle (ORC) module. The thermally conductive layer can be applied to pavements of new or existing roads, parking lots, roofs, or building walls, achieving the dual benefits of environmental cooling and energy reuse.

5. The intelligent thermal conductive pavement energy system as described in claim 1, wherein the sensing and control unit is used to sense the temperature of the pavement, and when the temperature of the pavement reaches a preset threshold, a circulation pump is started, the circulation pump causes the fluid to flow to export the heat energy for use by the heat energy conversion module, and the circulation stops when the return water temperature drops to 36°C–38°C.
