Default cooling by and not for PN junction

Hi people,

I have read something on a PN junction cooling device that is quite effective but I have forgotten to save it. Does any one of you know where to get information about this kind of device? Or did I just dream about that? It said in the article that it is so effective that condensation may develop on the cool side of the device. Any one has heard about that?


Thsnks for helping

Might you be speaking of a Peltier device (12V hot side/cool side).

Hi guys,

Thanks for the information. Looks like is a commerically available product. Any reason why our amplifier fanatics are not using them for output transistors cooling? They always want 'cool and quite'. These seems to be what they are after.

One side gets cool but the other side ends up quite hot. In fact, you end up having to remove the heat from whatever you are cooling plus the wattage of the TEC device from the hot side. So they are not used very often as ultimately you end up with even more heat that you have to get rid of.
