Abstract
A container construction and combination in which a container for confining water is provided with a metal heat exchanger disposed vertically within the container. The heat exchanger is comprised of inner and outer tube structures joined together in heat exchange relationship by fins extending between the tube structures, the fins having cross sections sized to conduct all the heat of a refrigerant in the inner tube structure to water located adjacent the outer tube structure. In addition, the outer tube structure has outwardly directed fins extending in a vertical direction within the container. The heat exchanger has upper and lower ends within the container, and means are provided for connecting the upper end of the heat exchanger to a source of heated refrigerant through an upper opening in the wall of the container, the refrigerant being vaporized when heated, and condensed when cooled in the heat exchanger. The vertical disposition of the heat exchanger permits the force of gravity to remove condensed refrigerant from the heat exchanger. Means are provided for returning condensed refrigerant to the source of heated refrigerant through a lower opening in the wall of the container, and means are provided to free the combination of galvanic action when water is present in the container.
