Going Forward, anyone replicating this design should make one crucial modification to this design. The Peltier devices need to be at the top of the space to be cooled, not the bottom, Warm air rises, to in order for the space inside of the cooler to be properly cooled, they need to be where the warm air collects. if you look inside of commercially made refrigerators the cooling ports are always at the top of the space being cooled, so they can properly wick away the heat inside of the insulated interior. Also, the small fans in front of the Peltier devices have no way for the air to get in behind the fans, so it is needed to have access for air inside of the cooler, to be able to run past the cooling pans of the Peltier device, so channels need to be put in the insulation to allow air to pass freely through the fins of the heat sinks of the Peltier modules, as they are right now, the fans are going to be ineffective at moving cool air from the fins into the coolers interior, and will burn out in short order because the fan will be working against itself. Other than these crucial alterations to this design, this cooler will be pretty effective, although I would want to make the front door out of solid insulation panel to keep the cold effectively inside or make the door out of two panes of plastic sheet with empty space in between them to provide a bit more insulation between the outside temperature and the inside temp of the cooler. But I would recommend the door be solid insulation panel and have the LED light on a switch in the frame, so that when the door opens, they then turn on, so it is easy to see inside. This is otherwise a great design and is likely pretty effective at keep drinks cold, although in its current form, the owner might notice the drinks at the bottom are colder than the ones at the top, as well as the ones in front aren't as cold as the ones in the back. if the changes were made according to my recommendation, the temperature inside would be much more uniform and colder than the way it is currently configured. Nice work friend! I hope you get more subscribers!!!
