Mini Hot Air Stirling Engine Motor Model Stream Power Physics Experiment Model Educational Science

Fans have excellent craftsmanship, made of metal. The , the faster you go A Stirling engine is a heat engine that operates through the cyclic compression and expansion of air or other gases (working fluids) at different temperatures, thereby converting thermal energy into mechanical work. The engine principle is intuitive, educational toys and teaching experiment equipment can effectively cultivate children's interest in learning, and can also be used in classroom teaching, which is more intuitive and easy to understand.
