Abstract
A two-phase liquid cooling system utilizes and evaporator unit for vaporizing a liquid coolant and a condenser unit for condensing the coolant vapor. The unit is capable of operating in at least two orientations: in one orientation, the condenser is located vertically above the evaporator and condensed coolant returns from the condenser to the evaporator under the force of gravity. In another orientation, the evaporator is located vertically above the condenser and the liquid coolant is returned to the evaporator by a stream of bubbles rising in a tube connecting the evaporator and the condenser. The stream of bubbles is produced by a small heater which is operated by a gravity controlled switch. A check valve is provided to insure that the bubble stream moves in the proper direction. The cooling system has at least one wall with sufficient flexibility that the wall expands as the coolant vapor expands thereby maintaining the internal container pressure substantially the same as the ambient environmental pressure.
