Stirling Engine Kit Tractor Design Vacuum Engine Motor Model Science Education Toy Gift – Enginediy
Working Principles:
The tractor vacuum engine heat dissipation method is air-cooled, and the engine is cooled by natural cooling after the air contacts the surface of the heat sink .
The closed cylinder should be filled with a certain volume of water . When the liquid is heated for expansion and compressed by cold compression, it will generate power, so that the tractor can move.
Features:
1, Novel Design: The Stirling engine is in the shape of a retro tractor, special and unique.
2, High Craftsmanship: The whole engine are made of metal, which is sturdy and durable, not easy to wear, and looks more retro after coloring. Pure Handmade, exquisite.
3, Educational Toy: Through hands-on operation, you can understand the engine working principle more intuitively by observing the whole engine running process, and deepen your interest in physics (this principle will be learned in the physics book of junior high school).
4, Ideal Gift Option for Many Applications: With competitive price and nice looking, the engine has a wide range of application as, great gift for Kids’ science project, Physical/mechanical learning, teacher’s Demo props on the class, birthday gift for friends, families, parents, kids, etc. Many of our customers come from school, colleague, etc.
