Gear casing heat exchanger

A gear casing heat exchanger comprising:

• a manifold section having a fluid inlet port, a fluid outlet port, an inlet manifold fluidly connected to the fluid inlet port, and a fluid outlet manifold fluidly connected to the fluid outlet port;
• a plurality of tubular fluid conduits, each fluid conduit having at least two straight sections joined by one or more bends and extending from an inlet end to an outlet end;
• and
• a cylindrical header receiving the inlet and outlet ends of the plurality of fluid conduits, a portion of the cylindrical header being received into an open end of the manifold section to fluidly connect the inlet ends of the plurality of fluid conduits to the inlet manifold and to fluidly connect the outlet ends of the plurality of fluid conduits to the outlet manifold.

A gear casing heat exchanger comprising:

• a heat exchange section arranged within an interior volume of a gear casing, the heat exchange section including a plurality of fluid conduits;
• a manifold section arranged external to said interior volume, the manifold section including a coolant inlet port and a coolant outlet port;
• a mounting flange arranged between the heat exchange section and the manifold section, the gear casing heat exchanger being secured to the gear casing through the mounting flange;
• and
• an o-ring seal arranged within a circular aperture extending through a wall of the gear casing.
