Kids Teachers Low Temperature Stirling Engine Motor Model Heat Steam Learning Education Tool to understand the working principle

Description

Type 1

This engine was invented by London’s Pastor Robert Stirling in 1816, so it’s named "Stirling Engine". Stirling heat engine is unique because of their theoretical efficiency is almost equal to the maximum theoretical efficiency, known as the Carnot cycle.  

Features:
Stirling engine model is an educational tool that explains the theory of air expansion and contraction.
By using this model, teacher can explain this theory in a much straightforward way and students will have better comprehension.
Just place it on a cup of hot water, and gently flip the wheel until the wheel can run automatically.
No need to fire an alcohol lamp, safer for children.
The high intensity PC material is heat-resistant and harmless. Transparent body gives you a clear view on how every parts work.
Fully assembled, no need to install it yourself. And the integrated ABS wheel will never deflect like the self-assembly ones.

Type 2

Stirling engine is a nice education model for students and teachers. It can help to better understand the working principle.

Features:
How it Works
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work.

A Great Explanation
Teacher can make the explaining process much straightforward and students can better understand its principle.

Safe Opeartion
Run freely on the top of a cup of hot water, no need to fire a alcohol lamp,safer for children.

Operating Requirement
Start temperature difference between the product bottom contact and circumstance should be greater than 25℃.  

Easy to Use
Gently flip the wheel, then it can run itself.

Considerate Design
Exquisite frosted plunger can avoid steam leakage and the reduce abrasion.

Note:If the friction between flywheel and support is big, please use a little graphite dry lube quiet it down nicely. Don’t use oil, because it will lead to oil-dirt.
