Yinhing Thermoelectric Cooler,Semiconductor Refrigeration Cooling Device Thermoelectric Cooler 12A 12V DIY Refrigeration Cooling System Mini Fridge

Thank you !!

It is my understanding that the big fans are supposed to be on the cooling side and they are not. Apparently mine was assembled backwards. It quit blowing cool air even out of the small fans after a little bit. Don't waste your money

Fits right into the food trailer ice box.

This cooling module ships wrapped in bubble wrap with no data sheet or any sort of documentation. Fortunately, the wires are all color coded: red for positive and black for negative. There are two separate cooling modules, each with its own pair of fans. Both modules are mounted to a large aluminum heatsink. After connecting it to a suitable power supply (not included), the small heatsink gets cool to the touch quickly. The smaller fan draws air over the small heatsink and blows cool air. The larger fans draw air over the large heatsink and blow warm air. This would be much nicer with better cable management. As shipped, there are six separate pairs of wires: one pair for each of the fans and one pair for each of the cooling modules. The wires are all different lengths, so you end up with a tangled mess of wiring. It's kind of pricey, considering you can buy a six pack can cooler for about the same price, but I'm hoping it's more powerful than a cheap cooler.

very good , good speed wind to circulate the air in my cheese cave
