Claim Text:
1. A cooling system for transferring heat from a heat load, the cooling system comprising: a two-phase working fluid; a pump configured to increase the pressure of the working fluid without substantially increasing the enthalpy of the working fluid; a first heat exchanger in fluid communication with the pump and in direct thermal communication with the heat load; a fluid-to-fluid heat exchanger having a first fluid path in fluid communication with the first heat exchanger and the pump, and a second fluid path, the first and second fluid paths being in thermal communication with one another; a second heat transfer system in fluid communication with the second fluid path and comprising: wherein the heat load in direct thermal communication with the first heat exchanger causes at least a portion of the two-phase working fluid to change phase from a liquid to a gas within the first heat exchanger; and a controller operatively coupled to at least the second fluid path and configured to prevent condensation on the first heat exchanger by controlling the amount of heat transferred to the second fluid path so that a temperature of the two-phase working fluid within the first heat exchanger is above a dew point temperature of air around the first heat exchanger.
