Searched for but found nothing, sorry if it's discussed elsewhere!
For those that never heard of it, a Peltier device is a small (40mm x 40mm x 4mm) and cheap
that uses electricity to transfer energy between two ceramic plates. It's used in aviation and boating
industry as cooling
element in electric
fridges, heat being dissipated by a huge cooler and fan. I recently got my hands on a 50 liter broken fridge I could fit such a device in, I got -5 C from +10 C in 30 minutes using a 60W device. Currently available from China
are 60W to 231W versions.
I'm thinking of two tanks
having one to many devices in between. With a max 70 degree Celsius difference, water
can not be used for the cold side, but an automotive coolant
running thru a freezer
is easy job.
Anyone thinking about something similar?
