Do you want to know how to make a diy mini fridge at home? This is the perfect video for you. Here, we show you the easiest way to build DIY mini fridge cheaply. After watching it your quest to learn a DIY fridge making process will fulfill.

The heart of this Refrigerator is a Thermoelectric Cooler Module. Thermoelectric coolers operate by the Peltier effect The device has two ( Hot and Cold ) sides, and when a DC electric current flows through the module, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter. The "hot" side is attached to a heat sink so that it remains at ambient temperature, while the cool side goes below room temperature.

A thermoelectric module consists of an array of p- and n-type semiconductor elements that are heavily doped with electrical carriers. The elements are arranged into an array that is electrically connected in series but thermally connected in parallel. This array is then affixed to two ceramic substrates, one on each side of the elements.

To make this Refrigerator, you have two options :
1. Buying the Peltier module, Heat Sink and Fans separately

2. Buying the entire unit which has everything.

After some inquiry, I have settled down to the second option. But if you have some old SMPS fans and CPU heat sink, then you can choose the first option.

The first and second pictures are downloaded from the web for easier understanding.

Connect the refrigerator to a 12V, 10A or more power supply.Then switched it ON, the LED should be lit up and you will hear the fan sound.Leave it for 10 to 15 mins. Now the cokes and chocolates are really chilled.

Enjoy !!!
