Stirling engine with fan blades, physics experiment teaching model, science popularization science making invention toy model

This unique Stirling engine model with fan blades perfectly combines precise mechanical principles with an intuitive demonstration of thermal energy conversion. It is not only a fascinating physics experiment teaching model but also a science popularization invention toy that sparks curiosity and educates through entertainment. It makes an ideal gift for children, students, and science enthusiasts.

Product Features:

• Intuitive Thermal Energy Conversion Demonstration: Through external heating (e.g., using an alcohol lamp, alcohol not typically included with the product), the engine efficiently converts thermal energy into mechanical energy, driving the striking blue fan blades to rotate rapidly. The entire process is clearly visible, vividly demonstrating the Stirling cycle and the law of conservation of energy.

• Unique Fan Design: Unlike traditional Stirling engine models, this version directly connects to fan blades. When the engine starts, the fan begins to spin, which not only adds dynamic visual appeal but also more directly demonstrates the effect of thermal energy being converted into kinetic energy.

• High-Quality Materials and Exquisite Craftsmanship: The main body is meticulously crafted from high-quality aluminum alloy and glass, with a smooth surface and stable structure. The transparent glass cylinder design allows for a clear view of the piston's reciprocating motion and the heat pipe's operation, showcasing the internal aesthetics of the machinery.

• Essential Tool for Physics Education and Science Popularization:

  • Classroom Aid: It serves as an ideal teaching model for school physics classrooms and laboratories, helping students more vividly grasp abstract concepts such as thermodynamics, energy conversion, and mechanical motion.

  • Home Learning: At home, it can spark children's interest in science and cultivate their observation skills and spirit of inquiry.

• Novel and Creative Gift: As a gift rich in technological appeal and educational significance, whether for birthdays, holidays, or as an award, it will bring surprise to the recipient, highlighting unique taste and encouraging their interest in scientific exploration.

• Simple Operation, Easy to Start: Simply add alcohol to the alcohol lamp and light it, place it under the heating end to preheat for a moment, then gently flick the flywheel (if necessary), and the engine will start running automatically, driving the fan blades.

• Stable and Durable: The solid metal base and precisely fitted components ensure stable operation and a long service life for the model.

Working Principle (Brief):

A Stirling engine is an external combustion engine that generates power by heating and cooling a confined working gas (typically air), causing it to expand and contract. When the hot end is heated, the gas expands, pushing a piston; when the cold end dissipates heat, the gas contracts, creating suction. This cyclical, reciprocating motion is converted into rotational motion of the flywheel via a crankshaft or connecting rod mechanism, which in turn drives the fan blades.

Let this Stirling engine model with fan blades be your excellent starting point for exploring the mysteries of science and appreciating the beauty of mechanics!
