I recall several years ago a round of articles/advertisements in the 
electronics hobbyist magazines regarding solid state cooling modules.
These were small blocks of several materials laminated together and
intended for portable electric picnic coolers.

As I understand it, when you ran current through this module one side of
the module would get warm and the other side would get cool.  When the
current was reversed, the warm side would get cool and the cool side warm.

I have a small computer in a sealed metal case, and I'd like to use one of
these things for managing heat buildup inside the case.  For condensation
reasons, I'd rather not just drill ventilation holes and install a fan.

Does anyone know where these cooling modules might still be available?

Can anyone suggest other approaches to this problem?

Regards,
Glen
