Discovery
I am using (2) two 113 Watt TE units in my DPSS build project. They are 60mm x 60mm.
Just a note.....if when you first get your TE units....you hook them up...right away to see if these things really work.....Well.....here is what happens....
At first...the one side gets cold,cold.....and the other side gets really hot...so far....this is what I expected....then...after about 30 seconds operating.....the cold side starts to get less and less cold....while the hot side gets really hot !!! I then said "S,P,D,H"...what is going on ????? Have I burned them up ?????? did I get a defective unit ???? NO...and NO !!
I discovered that you must have the hot side attached to a heatsink....so as to remove the heat out and away from the junction....and that without using a heatsink.....the hot side heat radiation just heats up the whole unit....at least that is how it is with the units I have....but I assume ALL
Peltier Junctions are the same !!
Possible....most of you allready know this !!! I did not !! Just a little note for anyone unfamilar with TE units.
