ABSTRACT:
There is described a device and process for effecting refrigeration by means of a thermoelectric element having a hot face and a cold face, which is powered by impressing a direct current across the faces, and in which the heat transferred to the hot face is dissipatead into an external thermal sink which is cooled by applying water to a surface thereof concomitantly with the exposure of that surface to ambient atmosphere. The thermal sink comprises a capillary metal sponge into which the water is absorbed on the capillary surfaces and evaporated while the sponge is exposed to the ambient atmosphere, whereby cooling is effected, both by direct heat transfer into said gaseous medium and by vaporization of said liquid.
