12V Peltier Effect – Cooler – Heater – 50W

Description

Hebei I.T. from Shanghai produces a great lineup of Peltier elements. We decided to add the 12V Peltier Effect element TEC1-12705 module to our catalogue because of its small size and impressive performance.

We used the 12V Peltier element TEC1-12705 to chill a can of beer within less than 5 minutes from room temperature to perfect drinking temperature.

Such an element can also help with overclocking high-performance processors by colling them down to freezing temperatures far below room temperature.

As soon as DC voltage is connected to the [+] and [-] wires, the hot side of the element starts to heat up and the cold side cools down. The effect is similar to a heat pump.

To avoid overheating on the hot side, sufficient cooling is necessary and typically done by a combination of a heat sink and forced air (fan).

I assume you know this effect from common camping cooler boxes. They usually have a fan inside to blow out the hot air, and a large aluminum profile inside to remove the warmth from inside the box.

The effect is reversed by changing the polarity of the connection.
