Making a mini refrigerator with your own hands
The refrigerator body is made of PVC pipes. How to make sheets and a body from PVC pipes, see more details here - https://home.washerhouse.com/en/6717-kak-iz-pvh-truby-sdelat-korpus-dlja-jelektroniki.html
To make the refrigerator more realistic, not just a box with right corners is glued together, but a body with semicircles. To do this, we cut the sheets along the radius.
Next we glue them together.
Glue the bottom of the refrigerator. We drill holes in the upper part for better cooling.
We cut out a circle from a porous PVC substrate along the diameter of a large cooler.
In the center of it we make a cutout for the Peltier element. We install it and fix it on the sides with glue. Lubricate the sides with heat-conducting paste. We attach a rectangle of aluminum and screw it to a large radiator.
Next, on the other side we screw on a small radiator.
We bring the wires to the top. We seal all cracks with hot glue.
We install this cooling element in the upper part of the refrigerator body.
We connect all coolers and fans in parallel to each other, then to the power connector via a button.
We cut out the walls of the refrigerator compartment from thin polystyrene foam.
Cover the top part with a strip with a built-in thermometer.
We make a loop from pieces of PVC.
We cut out the refrigerator door from plexiglass. Glue a loop to it.
Next, glue everything to the refrigerator.
We connect the refrigerator to the power source.
We put a couple of drinks and other treats inside.
After 40 minutes, the temperature inside the chamber dropped to 5 degrees Celsius. Thanks to the use of active cooling in the form of fans, this time is an excellent result.
