An improved apparatus for dispensing cooled, heated or ambient temperature liquids from a liquid tank which contains therein a cold sink member for maintaining the liquid at a preselected temperature. The cold sink member may be formed in the shape of a cup-like finned member or a tree-like shaped member having outwardly extending fingers in order to greatly increase the transfer of heat energy within the liquid tank and to reduce the thickness of boundary layer formation in the cold sink member. The apparatus includes adapter means operable to supply separately controlled, selective dispensing of any of the chilled, heated, or ambient temperature liquids.
