How does a stove fan work? (Peltier and Seebeck Effect)?

A stove fan uses heat to make wind, just like how blowing on a hot soup makes it cool faster.

When you turn on your stove, it gets really hot, like when you touch the handle of a pan after cooking. Now imagine there’s a special tile on the stove that can feel the heat and then move the air around it, like a little windmaker. That's what happens with Peltier and Seebeck effects.

Imagine you have two kinds of tiles: one is cold, and the other is hot. When they touch each other, the heat from the hot tile pushes the air around it, making a little breeze, like when you put your hand near a fan and feel the wind.

That’s Seebeck effect in action. It turns heat into electricity, which can power a small fan.

Now imagine you plug in a toy car, and suddenly it starts moving because of electricity. That's like what happens with the Peltier effect. When electricity flows through special tiles, one side gets cold and the other gets hot, just like when you put ice on your forehead to cool down.

So the stove fan uses both these effects to make a breeze that helps your food cook faster or cool it down quicker!
