Peltier Cooler Semiconductor Refrigeration Cooling System DIY Kit 12V 6A Thermoelectric Peltier for Mini Air Conditioner

I bought this for cooling optical experiments. Inserted into a 15L chamber I can reach around 4 deg C in 30 minutes. It is important to insulate the chamber-I used 1" foam. I increased the utility by replacing the 12706 peltier chips with 12710 ones.

I use this with water cooling. It does a great job. Gets so cold that the boxed heat sync actually frosts up.

Does not get as cold as expected

Took some actual readings across the coil and you'll be lucky to even get 1F Delta. It's more like 0.5F delta across. They claim 6A and it's only about 3A. What you DO GET is 154F on the hot side! 😂 There's an offset between the temp sensors of approx 0.5F orange reading higher than yellow. So based on that, look at the pics, you get barely any cooling at all.

Of course, it heats just as well. The package here is well designed, tight but as a novice some guidance around proper mounting (direction of translucent plastic flange, routing of wires term on 2 sides to source) would be helpful. I've sorted and tested, but need info: 1 peltiere module is used, mfg & part no? One mfg (liscensed) claims dramatic longevity ++ & need to eval for planned replacement.

The product was delivered on time, fully corresponds to the description and meets my expectations.

I tried fixing my cheap wine cooler with this as the wine cooler had a smaller Peltier. Neither of them worked. If you want to chill wine get one that has a compressor and spend the money or drink less.

Instead of buying a new compressor, , I just removed the evaporator fan and slapped one of these in. It works well so far , and the water fountain thermostat is compatible with the unit.

No gastes tu dinero, no sirve.
