A black phosphorus / sodium bromide stack near-field radiant thermal photovoltaic power generation device based on the waste heat of diesel engine flue gas. The invention belongs to the field of waste heat power generation systems of diesel engines. The purpose of the present invention is to solve the technical problems of limited application and low efficiency of the existing circulating waste heat power generation system due to its own volume and mass limitations. A black phosphorus / sodium bromide stack near-field radiant thermal photovoltaic power generation device based on the waste heat of diesel engine flue gas of the present invention includes a flue gas heat exchanger, a heat conduction gasket, a heat emitter, a photovoltaic cell, A heat sink and a piezoelectric nano-displacement device, there is a nano-scale vacuum gap between the heat emitter and the photovoltaic cell, and the size of the vacuum gap is controlled by the piezoelectric nano-displacement device. The thermo-photovoltaic power generation device of the present invention realizes miniaturization and light weight of waste heat utilization equipment, and also converts waste heat of diesel engine flue gas into direct-current electric energy that can be directly used without additional pipelines and mechanical components.
Description
technical field [0001] The invention belongs to the field of diesel engine waste heat power generation systems, in particular to a black phosphorus / sodium bromide stack near-field radiant heat photovoltaic power generation device. Background technique [0002] To ensure the security of oil supply, it is necessary to reduce the import of oil, which can be achieved in two ways. One is to develop alternative fuels and reduce dependence on oil through technological progress. The other is technological innovation in all walks of life to improve energy utilization or waste energy recovery. [0003] In recent years, awareness of the use of low-grade heat sources has attracted extensive research by researchers around the world. Especially in the field of diesel engines, due to the increase in fuel costs, people are gradually turning their attention to how to further improve the fuel efficiency of diesel engines in order to obtain higher quality propulsion systems and lower operatin...
