Peltier (sp?) device. Available from Digi-key and other sources.
Small ones are around $25-$30. 
Pass currect through in one direction, one side gets hot, while other gets cold.
reverse current and the sides swap termperatures.
Kinf-of a solid-state heat-pump.
Seem to be in all the surplus magazines they send me.

Good luck,
Ken.
