DC 12V DIY Thermoelectric Peltier Refrigeration Cooling System Kit Semiconductor Cooler Heat Sink Conduction Module Fridge Mini Air Conditioner Refrigeration

Perfect to cool down your dcdc charger in your ute tub

Takes 6.5 amps so needs a 240v to 12v converter off shore power when engine not charging battery.

The cooler is well built, and I bought it to play with and see if I could add it to my mini fridge when I was done. You must remember that you will need a 5 amp power supply and a temperature control module. I had it running stand alone in open air for hours turning on and off. I could not add it to my mini frig, but I still have it around for another project.

Tested but temperature can go below 25C. Will have to replace Peltier to see if it's faulty. Driven to 12.5V and 5A after trying at fixed 12V.

I have purchased this thermoelectric cooling system for a project of mini fridge and the results are interesting, but require technical attention. Key points after use: Cooling capacity: The Peltier module performs its function. It manages to lower the temperature steadily, but it is vital to ensure good thermal contact. Installation: The kit comes pre-assembled, which is appreciated, but I recommend checking the screws. In my case, I had to adjust them a bit to improve the pressure on the plate. Noise: The fan is standard. It's not ultra-silent, but for a workshop environment or inside a cabinet, the noise level is acceptable. Consumption: Operating at 12V, consumption is stable. Make sure you have a power supply with enough amperage (I recommend at least 6A so you don't force the supply). Pros: Good size heat sinks for the price. It's easy to integrate into small projects. Cons: It doesn't include detailed instructions, so if you're a beginner, you'll need to look for external diagrams. Short cables according to your box design. Verdict: It is an excellent choice for DIY enthusiasts. Don't expect to cool a room (it's not a real air conditioner), but for small compartments or component cooling, it works great if the hot air outlet is managed well.
