Peltier Effect - Unwanted Ice Cubes
About 20 years ago I had a cool box on my boat that worked with a Peltier Module. One summer I decided I wanted some nice cool beer for the following weekend. So on Sunday evening, I packed it full of cans and plugged it into the boat's battery system and went home. On the following Friday, I arrived at the marina expecting to have a cool beer or two before hitting the bunk!
All I had was an ice cube and a broken cool box. The vent above the small fan had frozen up completely, freezing the fan and the electric motor in a block of ice. Even after de-icing, the motor no longer functioned.
I ended up buying a Waeco cool box with a compressor.
But I have still got the original box somewhere, and I might just try and get that Peltier module out of the lid if I don't have to operate on it extensively with a Dremel.
About 20 years ago I used to sail the Channel and around Ireland...What I needed then was not a Peltier thingy, but a good stove ! Thankfully there were pubs...
Finally extracted the Peltier unit from the lid of the cool box. but unfortunately, there are no markings stencilled on the surface. I measured the resistance of the unit and my multimeter shows between 6 & 7Ω.
So I assume a current draw of 2A @ 12V.
@dronebot-workshop Let me know if I am wrong.
Stuffed a few old socks in the space where these heat sinks resided, so the better half can still use it when de-frosting the deep freeze, but I shall replace the socks with building foam sometime.
If it works then it will become part of my Arduino controlled, Vodka & Tonic cooler.
The next great Pugwash invention, bound for the Instructables website. ? ? ?
