Anti-heating by Water for a Thermoelectric Cooler





Introduction: Anti-heating by Water for a Thermoelectric Cooler

In my first post i want to show you how to make an anti-heating system for a thermoelectric cooler that works with (cold) water.

as you know the anti-heating by the air isn't very strong and I was thinking about to make a system that can with water to anti-heated it.

you can develop it in every way you want. (for example: smaller version, lighter and moveable)

Step 1: Materials

1x computer fan (used size : 8*8)

1x thermoelectric cooler (used: TEC1-12706)

1x (cpu) heat sink (used size: 7.5*6)

1x metal pot (for put water in it)

1x ATX power supply (used: porsche 450W)


some ice (optional but it can perform it faster)

you can use any power supply but it must exactly feed your things.

Step 2: Assembling

put the fan in the pot and heat sink above it.

put water in pot to reach the upper point of heat sink blades. (the red line is the maximum level of the water)

and put your ice.

then put your thermoelectric cooler on the heat sink.

Step 3: Finish!

connect the fan and cooler wires to power supply and turn it on.

you can see the ice in images and the video that zipped.

    Are you actually covering the fan with water? That´s brave. The fan is not waterproofed, and you might get problem later on. Or have I missunderstood?

    your right but I don't have ever any problem with it.

    did you put your finger in the water while it is running? :)
