Thread: A mini refrigerator

Hi I'm a student so I don't really know how to do this and I was wondering if anyone had a guide or even just a blueprint of a standard refrigerator, I plan to make a small refrigerator for personal use but have no idea where to start, thank you in advance to those who answers ^^

Aside from the fun of building your own, you could buy a mini fridge relatively inexpensively.
Refrigeration is a matter of moving heat.

Take a propane burner and use that to boil water in a boiler. Create steam.
Run the steam through an evaporator where it expands quickly- that energy must come from somewhere... so it draws it out of the surrounding heat.
Many campers still have propane run refrigerators.

The easiest wat to build a cooler is to use a "Peltier Device" It is a solid state device that when powered by direct current moves heat from one side to the other. One side of it gets hot while the other gets cold. By placing heat sinks on both sides and thermally isolating them from each other you have a heater and a cooler. You can build a small, insulated box, mount the device in one wall of the box and with a fan to remove the heat they work well. They are available commercially (I bought one for $0.50 at a garage sale. They plug into an auto cigarette lighter plug.

Why make one when you can find lots of inexpensive mini refrigerators? You don't really need to exert a lot of effort and consume plenty of your valuable time figuring out how to create a mini refrigerator. All you have to do is browse the internet for great deals on mini fridges. If you do this, you will not only save time and money but you will also save yourself from all the hassle of making a compact fridge of your own.

As I already said- there are great rewards in learning how to do for yourself, as much as rewards in acquiring.
