Patent ID: 6990816

Claim:
A cooling apparatus comprising; at least one evaporator comprising an enclosure from which all non-condensable gases have been evacuated, the enclosure including a capillary wick in contact with an interior surface receiving heat from means external to the evaporator, a vapor space for receiving vapor evaporating from the wick, a liquid inlet admitting liquid into the enclosure, at least one liquid source supplying liquid to a surface of the wick, an excess liquid outlet for removing excess liquid from the enclosure, and a vapor outlet accessible to the vapor space for removing vapor from the enclosure; a condenser comprising an enclosure, a vapor inlet interconnected with the evaporator vapor outlet by a vapor transporting structure, an interior surface cooled by a means external to the enclosure, and a condensate outlet removing liquid condensed within the enclosure; a reservoir comprising an enclosure holding liquid, a condensate inlet interconnected with the condensate outlet of the condenser by a liquid transporting structure, a liquid outlet interconnected with the evaporator liquid input by a liquid transporting structure, and an excess liquid inlet interconnected with the excess liquid outlet of the evaporator by a liquid transporting structure; and a pump interconnected with the reservoir and the evaporator and moving liquid to the evaporator from the reservoir.
