Peltier Driven Woodburner Fan

This woodburner fan was inspired by the stirling engine fans available for purchase on the net.

The aluminium block/peltier cell/heatsink sandwich was salvaged from an inexpensive electric refrigerator.

No information on voltage and power, but it certainly shifts enough air to raise the temperature of the room.

And it's quieter than a stirling! :-)

Whats the name of the song?

@intheshitter Sorry I don't know. It was copyright free music downloaded from somewhere or other.

just got my woodburner fired up and was thinking of one of these fans...where did youy get the peltier module from?

[mowerofdoom]

It's from a cheap electric fridge/food heater. You can also find the elements for around 20-30 pounds. The motor is a low drain solar motor.

I like the ribbon to show the air movement ! Might try that on my video

Cheers for the quick reply, can you tell me what the prop is made of, i'd have thought a plastic one would eventually melt ?

[finchpaul]

I made one of these using two peltiers, it wasnt as good as this, this my propellor was to heavy and i used the wrong engine. Can you tell me what engine your is and is your prop metal of plastic ?

Does it stop or slow down significantly as the peltier module heats up? In a mini-fridge, you need power to exhaust the heat away. And the module looses efficiency as the two sides equalize in temperature.

How hot is too hot for the peltier to withstand?

[fronkenpoop]

Very nice.

Looks like the type of motor commonly found in portable cassette tape players and CD players.

I have a few of those motors as well as a few peltier modules. Might try this! I had no idea you could generate enough power for something like this using a peltier.
