两级密封式斯特林可逆热机

介绍一种两级密封式斯特林可逆热机。该机按斯特林循环正向运行，将热能转变成电能；按斯特林循环逆向运行，将电能转变成热能，突破了现代斯特林发动机、斯特林制冷机都不能逆向运行的技术难关。通过两级密封技术、工质自动均衡技术、螺旋逆流换热技术的综合应用，彻底清除了斯特林热机发展的两大障碍：一是结构复杂．二是密封困难，提供一种结构简单、密封可靠、使用方便、运行平稳、节能环保、造价低廉的斯特林可逆热机，可广泛应用于发动机、制冷机、热泵等三大技术领域。尤其是在低温制冷和高温制热这两方面，较现有技术更具优势．

A Two-step Sealed Reversible Stirling Engine

This paper introduces a two-step sealed reversible stifling engine which can transform heat energy into electricity when running for-ward stirling cycle and also can transform electricity into heat energy when running backward stifling cycle. Neither actual stirling motor nor refrigerator has reversibility, so this two-step sealed reversible stifling engine is a great breakthrough in the stirling engine. By employing two-step sealed eonfiguration ,spiral countercurrent heat-exchanger and self-equilibrium system of working substance, the main troubles,configura-tion complexity and seal problem, which block development of the stirling engine, are solved eompletely. The two-step sealed reversible stirling engine can be widely used as motor,refrigerator and heatpump and has much lower manufacturing and running cost than the actual engine es-pecially in low-temperature refrigerator and high-temperature heatpump.
