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
heat pump 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?
