3 Sets TEC1-12706 Peltier Cooler Module kit 6A 12V Cooling Panel + Aluminum Heat Sinks + 12V Cooling Fan

Great teaching set for my 9yo twins as it has everything you need to demonstrate the thermoelectric effect as long you have standard teaching tools for science and engineering. For teaching here’s what else you need/want to demonstrate full functionality: A 12 or 24 volt DC power source (ex: car battery) A contactless thermometer A multimeter A dual-probe thermometer that can simultaneously measure, chart, and display two temperatures Something fun to heat or cool, we did my kids water bottles and my coffee cup to show how you can heat and cool at once A hot and cold source (ice water and coffee as above) to show this running “backwards” and generating electricity.

Buen producto

seems pretty good for my needs but when i applied voltage to the cooling device it felt cold for a moment then got very hot

This company is a zero. I returned the coolers because they overheated and overwhelmed the cool side. They now claim the product was not in the box. I’m furious that they are telling Amazon a lie. I have a completely perfect relationship with Amazon. I trust them with my purchase. It seems I have no recourse. So I will continue to repeat this message so all future purchases from this company are met with SCRUTINY!

Excellent kit for getting started with peltier thermoelectric modules. Aside from a power source and thermal paste, this is all you would need to get started. I have run as little as 3.7v through a plate and fan combo with rapid results.

Son muy pequeñas, mas de lo que esperaba, seguramente debi verificar las dimenciones... sin embargo estas celdas peltier no enfriaban , lo hacian muy muy poco... piendo que no son buenas., no se si habra otras de otra referencvia mejores. no sirvio para mi objetivo.

Great little Peltier cooler/heater
