Title: SYSTEMS AND METHODS FOR COOLING COMPONENTS WITHIN A GAS TURBINE ENGINE
Abstract:
A passive heat exchanger includes an evaporator section including a heat exchange surface formed complementary to a surface of a gas turbine engine component to be cooled. The heat exchange surface is configured to be thermally coupled in conductive contact to the component surface. The heat exchanger further includes a condenser section coupled in passive convective flow communication with the evaporator section, and a working fluid contained within the evaporator section and the condenser section and configured to passively convect heat from the evaporator section to the condenser section.
