TWO-PHASE COOLING WITH AMBIENT COOLED CONDENSOR

摘要

An apparatus for cooling a computer system includes a primary cooling loop. The primary cooling loop includes an evaporator configured to cool at least a component of the computer system, an ambient cooled condenser connected to the evaporator, a first pump to provide a coolant flow within the cooling loop, a pressure regulator configured to maintain a selected pressure in the primary cooling loop, and a controller responsive to changes in outdoor ambient conditions and an amount of heat dissipated by the computer system and configured to dynamically adjust the pump and pressure regulator in response thereto.

1. A method of cooling a computer system, comprising
determining an outside ambient temperature; determining an expected amount of heat to be dissipated from said computer system; setting a pressure of a liquid coolant that minimizes an amount of energy needed to condense a vaporized coolant into a liquid coolant, wherein said pressure is set based on a temperature-delta above the outside ambient temperature and the expected amount of heat; evaporating the liquid coolant from high heat density components of the computer system wherein a vaporized coolant is formed; and condensing the vaporized coolant into a liquid coolant.
