Ok, finally got my lazy butt in gear and took some pictures.
I got this idea in my head after seeing a few wine fridges on Craigs list for free or almost free($20). Insulated, nice glass door to watch the process and cheap but mostly not working.
As I found out most of the thermoelectric fridges are made in China. The thermoelectric units(TECs) that cool the fridges are not the best quality and are the first to break down. I found some replacements for this fridge on ebay for $2.
TECs are a flat square ceramic unit with two wires, a positive and a negative. Heatsinks and fans are attached to both sides of the TECs to remove the hot or cool air. When you run 12v DC through the TEC, one side will become hot and the other cool. If you reverse the + and - the opposite sides will be hot and cool. This, in theory, will keep the fridge at a constant temp.
OK, so this is what I started with… a Haier fridge.[attachment=2]HVTB18DABB-Haier.jpg[/attachment][attachment=1]HVTB18DABB.jpg[/attachment]
I placed it on it’s side, removed the shelves and divider. Moved the LED light from the middle shelf to the ceiling. Moved the light switch from the side to the top of the fridge. Removed the LCD temperature control - I didn’t disconnect it in case it stopped working so I just left it on top.[attachment=0]DSCF3247.JPG[/attachment]
