Description

technical field [0001] The invention relates to a thermoelectric power generation device and a method for making a concrete wall, in particular to a thermoelectric power generation device for a concrete wall and a method for making the graphene-concrete wall. Background technique [0002] The rapid development of urbanization has had a serious impact on urban temperature, and the urban heat island effect is becoming more and more obvious. The rise in temperature will bring more energy consumption. Research shows that for every 0.1°C rise in the average daily temperature of Nanjing in August, the average daily temperature of the month will increase. The maximum electrical load will increase by 41,000 kW. [0003] Under direct sunlight in summer, urban roads and roofs can reach above 65°C, and the temperature difference between indoor and outdoor can reach above 40°C. This invention uses the heat collection system to collect heat and solar energy in the city on the walls and ...

AI Technical Summary

Problems solved by technology

Although this system uses thermoelectric materials to generate electricity by temperature difference, there are mainly the following problems: (1) placing thermoelectric materials inside the wall destroys the integrity of the concrete in the wall, reduces the bearing capacity of the structure, and poses safety hazards ; (2) Space needs to be left in the wall to store thermoelectric materials, which cannot be used in many occasions such as high-rise buildings, bridges, roads, etc.; (3) The construction process is complicated, the cost of thermoelectric materials is high, and the energy conversion efficiency is low. Poor application prospects

[0006] To sum up, the existing technology still has problems such as insignificant temperature difference between the cold and hot ends, inability to fully utilize the bearing capacity of concrete, and high construction and post-maintenance costs.
