Patent ID: 7861512

Claim:
A cooling apparatus for cooling a fluid in a bypass gas turbine engine, the apparatus comprising: a heat exchanger defining a fluid passage, the heat exchanger being disposed within an opening in an annular outer wall defining an outer periphery of a bypass duct, the heat exchanger being attached to the outer wall and protruding radially into the bypass duct; a flow divider extending radially into the bypass duct and affixed to the outer wall of the bypass duct, the flow divider in combination with the wall of the bypass duct forming a sub-passage for communicating bypass air from the bypass duct to the heat exchanger, the sub-passage defining an open upstream end and an open downstream end each extending into the bypass duct to direct a portion of the bypass air flow to pass therethrough; wherein the heat exchanger comprises a cover plate affixed therewith, the cover plate being removeably attached to the outer wall of the bypass duct in order to close the open area thereof and support the heat exchanger in position; and wherein the heat exchanger comprises an inlet and an outlet in fluid communication with the fluid passage defined therein, the inlet and outlet extending out of an outer side of the cover plate.
