Looking to install an outdoor enclosure housing cctv equipment. Was wondering if this unit would be suitable for maintaining an acceptable internal temperature in full Qld sun?


Hi Jamie
Depends on how big your enclosure is and if it is in direct sunlight.

I mounted a similar size one made up in a similar setup with heat sink and fan into the lid of a smaller (maybe 12 can) Esky type cooler. Worked well for what it was used for. I later had a larger commercial one which I don’t know what size Peltier device was in it and this unit struggled a bit on a hot day in the back of my car. But having said that, it did work. If you have use for the feature these devices will heat by reversing the battery connections. I reversed the fan direction as well with my home made unit.

One thing to remember is these things only reduce the temperature XºC below AMBIENT. If the demo got to -3ºC I would say the trial occurred in an already cold air conditioned room. The Peltier devices do work but if you want or need more grunt you need a bigger device and consequently more current. They come in different sizes.
