The invention relates to a compact microscale thermal energy power system, which belongs to the field of thermodynamics. The system comprises a burner, a porous medium, a turbine, a fan, an exhaust pipe, an air inlet pipe, a fuel tank, a fuel delivery pipe, an expansion bag, a heat pipe, a thermophotovoltaic material, a starting motor, a heating piece and a fuel regulating one-way valve. The system can convert chemical energy stored in a liquid hydrocarbon fuel into electric energy; continuous running of the system without an outside energy source can be realized by virtue of chemical reaction of the system and internal energy and substance transfer; the system is compact in structure, perfect in function and novel in concept, and is a very dominant novel product; and the system converts the chemical energy stored in the liquid hydrocarbon fuel into the electric energy efficiently and quietly based on a microscale combustion principle, and is very suitable for serving as single-person power supply equipment for personal computing and communication equipment, armies and quick response departments, and power supply support equipment of special industries under severe conditions at present and in future.
Description
technical field [0001] The invention relates to a compact microscale thermal energy power system, which belongs to the field of thermodynamics. Background technique [0002] Liquid hydrocarbon fuels have high energy density and good transportation / storage performance. The concept of placing liquid hydrocarbon fuels in tiny containers for micro-scale combustion to obtain long-term high-density electric energy has been proposed at the end of the last century, but due to Due to the basic principles of combustion and the limitations of the characteristics of micro-scale combustion, it is difficult for liquid fuels to burn continuously and stably in tiny containers, thereby releasing heat and outputting electrical energy. The main reasons for this phenomenon are as follows: [0003] 1. In micro-scale combustion, the area / volume ratio of the device is very large, resulting in serious heat loss per unit volume, and the heat released by the chemical reaction is not enough to keep i...
