Patent ID: 7549461

Claim:
A system comprising: a primary evaporator operable to facilitate heat transfer by evaporating a received liquid to obtain a vapor, the primary evaporator including a first port for receiving the liquid from a liquid line, a second port for outputting the vapor to a vapor line, and a third port for outputting excess liquid received from the liquid line to an excess fluid line; a condensing system operable to receive the vapor from the vapor line, to condense at least some of the vapor, and to output the liquid to the liquid line; a reservoir in fluid communication with the condensing system, wherein the liquid is obtained at least partially from the reservoir; a primary loop including the condensing system, the primary evaporator, the liquid line, and the vapor line, the primary loop being operable to provide a heat transfer path; and a secondary loop including the condensing system, the primary evaporator, the liquid line, the vapor line, and the excess fluid line, the secondary loop being operable to provide a venting path for removing other vapor that is present within the liquid from the primary evaporator.
