ABSTRACT:
A heat transfer device comprises two kinds of liquid having different boiling points and specific gravities, said two kinds of liquid being not mutually dissolvable and charged in a vessel so as to form two layers therein in superimposed relation to each other. In the heat transfer device, a large amount of heat is transferred at temperatures above a certain temperature but unidirectionally, while no heat transfer is effected at temperatures below the aforesaid certain temperature. The heat transfer device is suited for use in such apparatus or machines which require a thermally valving function, especially for use in a refrigerator.
