Description

technical field [0001] The invention relates to a waste heat utilization system, in particular to a thermoelectric power generation system. Background technique [0002] With the development of the economy, the human demand for energy continues to increase, and the environment is constantly polluted, resulting in resource shortages and environmental damage. At present, the rapid development of industrialization is accompanied by the generation and discharge of various waste heat. However, waste heat utilization technologies such as absorption heat exchange units and heat pump units for waste heat recovery in my country are still in the research and development and small-scale test stage, and because of the limitations of complex mechanical parts, low efficiency, and high investment costs of the units, the promotion of waste heat utilization technologies is affected. . Although semiconductor thermoelectric power generation technology is just in its infancy, it has been used ...
