Abstract:
1. A heat transfer system, comprising: an evaporator thermally engageable with a heat source and including an evaporator cavity holding a working fluid; a condenser having a ceiling, a floor, one or more perimeter walls extending between the ceiling and the floor at the perimeter of the ceiling and the floor, one or more internal walls extending between the ceiling and the floor inside the perimeter walls, and a continuous condenser cavity between the ceiling, the floor, the perimeter walls and the internal walls, wherein the continuous condenser cavity is in fluid communication with the evaporator to receive vaporized working fluid from the evaporator, wherein the evaporator and the condenser are adjacent to each other such that a thin wall forms at least a portion of both the top surface of the evaporator cavity and the bottom surface of the continuous condenser cavity; a first fluid transfer path extending from the evaporator to the condenser for movement of the vaporized working fluid from the evaporator to the condenser; and a second fluid transfer path extending from the condenser to the evaporator for movement of condensed working fluid from the condenser to the evaporator, wherein the second fluid transfer path is separate from the first fluid transfer path; wherein at least one of the first fluid transfer path or the second fluid transfer path is integrally defined by the evaporator or condenser, and further wherein the continuous condenser cavity extends laterally beyond the perimeter of the evaporator cavity, wherein the evaporator is sealed such that the working fluid is only able to exit the evaporator by entering the condenser.
