Range extending type electric automobile system with thermo-acoustic generator

Abstract

The invention discloses a range extending type electric automobile system with a thermo-acoustic generator. The range extending type electric automobile system is characterized in that a range extender unit of the range extending type electric automobile system is composed of the thermo-acoustic generator and a second power converter; the thermo-acoustic generator is composed of a free piston Stirling generator, a combustor system and a room temperature radiating loop; a fuel box provides fuel for a combustion chamber; an air inlet pipe and an air outlet pipe are arranged at the upper end of the combustion chamber and are connected with a counter flow heat exchanger; the free piston Stirling generator is formed by coupling a free piston Stirling engine and a linear oscillation motor; an engine expansion cavity, a heat absorption end internal heat exchanger and a heat discharging end external heat exchanger are arranged in the combustion chamber; the radiating loop is composed of a water inlet pipe, a water amount control valve, a water valve, a radiator, a water outlet pipe and a fan on one side of the radiator, wherein the water inlet pipe, the water amount control valve, the water valve, the radiator, the water outlet pipe and the fan are connected in sequence. The water inlet pipe and the water outlet pipe are connected to the heat discharging end heat exchanger of the engine. The two ends of the second power converter are connected with the free piston Stirling generator and a power storage battery. The range extending type electric automobile system has the advantages of being high in efficiency, wide in fuel applicability, high in reliability, silent, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a generator system of an extended-range electric vehicle. Background technique [0002] The rapid development of the modern automobile industry has greatly changed the production and lifestyle of human beings. It not only improves the quality of life of human beings, but also becomes one of the very important pillar industries that promote economic and social development. However, due to the constraints of fuel, combustion methods and operating conditions, the automobile industry with internal combustion engines as its core power has also brought a series of serious problems to modern society, such as energy crisis, climate warming and environmental pollution. Especially environmental pollution, the high levels of PM2.5 and other pollutants caused by automobile exhaust emissions have seriously threatened human health and become an important shackle restricting the further development...

AI Technical Summary

Problems solved by technology

Although the gasoline engine can work in the stable zone through parameter matching and control strategy optimization, it has lower fuel consumption and exhaust emissions than the traditional gasoline engine providing full power, but the characteristics of the internal combustion engine determine its efficiency, fuel There are deficiencies in applicability, reliability and environmental protection, which cannot fully reflect the advantages of extended-range electric vehicles
