Stirling engine based on repeated piston heating

Abstract

The invention belongs to the field of Stirling engines, and discloses a Stirling engine based on repeated piston heating. The Stirling engine comprises a waste gas treatment device, a heat exchanger, a refrigerating device, a compressor, a transmission shaft, a worm wheel, a Stirling hot end heating chamber, a Stirling hot end, a Stirling cold end refrigerating chamber, a Stirling cold end, a fuel gas generator and the like. Repeated piston double-cylinder burning gas supply is adopted by a heating system, burning power is carried out on two sides of a piston, a high power-to-weight ratio is achieved, and the heating efficiency is favorable to be improved; the worm wheel drives the refrigerating device at the same time, the air is cooled, the cold end of the Stirling engine is cooled, and therefore the efficiency of the Stirling engine is improved. A hot end supply system which is high in power-to-weight ratio and clear is designed, the temperature of the cold end is lowered at the same time, the efficiency of the Stirling engine is improved and the emission is reduced, and a good marketing prospect is achieved.

Description

technical field [0001] The invention belongs to the field of Stirling engines and discloses a Stirling engine based on repeated piston heat supply. Background technique [0002] At present, the hot end of the Stirling engine mostly uses solar energy or uses various fuels in the field to burn, and the cold end is generally air-cooled. The research focus is often on the high efficiency and cleanliness of the entire system for heating at the hot end, and less consideration is given to the integration of the hot end and the cold end. use. For a Stirling engine, the greater the temperature difference between the cold end and the hot end, the higher the power and efficiency of the engine. The present invention intends to comprehensively consider the temperature difference between the hot end and the cold end to design a clean hot end supply system, and at the same time The temperature of the cold end is reduced, and the efficiency and power of the Stirling engine are improved.
