Low Temperature Sterling Engine Physics Science Model Desk Toys Collection Gift

Description: Item Description Item Name: Metal Low Temperature Stirling Engine Model Package Includes: 1*Low Temperature Stirling Engine Kit（Other products are not included） Material: Stainless steel+Aluminum Alloy+Brass Color: Silver Engine Size: 105 * 105 * 140mm Engine Weight: Approx. 530g Flywheel Diameter：65mm Piston Diameter:16mm Piston Stroke : 8mm Ages: 16+ Function: This is a low-temperature Stirling engine designed by us. Its principle is the same as that of a high-temperature Stirling engine, both requiring the creation of a favorable temperature difference as the source of power for the machine.Since low-temperature Stirling engines do not use open flames, only utilizing heat sources below 120 degrees (normally using boiling water above 80 degrees), this necessitates the design of a larger heat exchange cylinder for the machine. Our easy-to-operate engine is powered by the temperature differential between top and bottom panels. Simply take it out of the box, place it over a mug of hot water, give the flywheel a gentle push, and witness the marvel of movement in no time!High-Performance Stirling Engine: Designed to outperform traditional models, our Low Temperature Stirling Engine uses self-lubricated graphite power piston for less friction and durability, and stainless steel string as the connecting rod for efficiency. How to Use: Place the machine on a flat table during operation and pour the boiling water with a water cup capacity of 4/5 or more, heat for about 20 seconds, and start flywheel by hand.Exquisite design, beautiful appearance, designed with a special double flywheel, the base is square.Through the hands-on operation, you can observe the entire low temperature Stirling engine operation process, more intuitive understanding of the Stirling principle, and deepen your interest in physics. Safety Tips Place the machine as far as possible in the center of the cup to prevent the machine from losing balance and falling off the cup.Except for the bottom heated surface, the machine is prohibited from contact with water at other locations; It is forbidden to use open flame heating, and it is forbidden to use heat sources with temperatures above 150 degrees; Contact the high temperature parts of the machine to prevent burns.
