Abstract
An apparatus and method for cooling a fluid within a turbine engine. A fan casing assembly for the turbine engine can include an annular fan casing with a peripheral wall having a flow path defined through the casing. A fan casing cooler includes a body to confront the peripheral wall with at least one conduit configured to carry a flow of heated fluid to convectively cool the heated fluid with a flow of air through the flow path.
Claims16
A fan casing cooler for a fan casing having a peripheral wall, the fan casing cooler, comprising:
- a body having at least one conduit therein, an exterior of the body defining a first surface confronting the peripheral wall, a second surface that is opposite the first surface, and at least one thermally sensitive portion at least partially defining the first surface;
- and
- at least one hinge provided in the body wherein the at least one hinge comprises a channel recessed into the second surface of the body;
- wherein the at least one conduit is configured to carry a flow of fluid proximal to the second surface and arranged to transfer heat from the fluid to air flowing through the fan casing and the at least one thermally sensitive portion is arranged such that in use and in response to a change in a thermal condition at least a portion of the fan casing cooler is passively positioned away from the peripheral wall of the fan casing and into the air flowing through the fan casing.

A heat exchanger body, comprising:
- at least one conduit;
- a first surface defining a first exterior surface;
- a second surface defining a second exterior surface, the second surface opposite the first surface;
- at least one hinge in the body wherein the at least one hinge comprises a channel recessed into the second surface of the body;
- at least one thermally sensitive portion at least partially forming the heat exchanger body and defining at least a portion of the first surface, the thermally sensitive portion configured to change shape in response to a change in a thermal condition;
- wherein the at least one conduit is configured to carry a flow of fluid proximal to the second surface to transfer heat from the fluid to an airflow passing along the second surface and the thermally sensitive portion is configured to passively position at least a portion of the heat exchanger body into the airflow.

A cooler assembly for an engine casing having a peripheral surface and a gap in the peripheral surface, the cooler assembly, comprising:
- a body defining a periphery including a first surface and a second surface that is opposite the first surface;
- at least one hinge in the body wherein the at least one hinge comprises a channel recessed into the second surface of the body;
- at least one conduit located within the body, the at least one conduit configured to carry a flow of fluid proximal to the second surface;
- and
- at least one thermally sensitive portion included within the body and configured to, in response to a change in a thermal condition as an increase in temperature or a decrease in temperature, passively position at least a portion of the body into an airflow flowing along the second surface or passively position the at least a portion of the body into the gap in the peripheral surface of the engine casing, depending on whether the change in the thermal condition is the increase in temperature or the decrease in temperature.
2 more elements
A heat exchanger body, comprising:
- a first surface a second surface opposite the first surface;
- discrete fins on a portion of the heat exchanger body opposite the first surface;
- at least one hinge provided between at least some of the discrete fins wherein the at least one hinge comprises a channel recessed into the second surface;
- and
- at least one thermally sensitive portion at least partially forming the heat exchanger body and defining at least a portion of the first surface, the thermally sensitive portion configured to change shape in response to a change in a thermal condition;
- wherein at least one conduit is configured to carry a flow of fluid proximal to the second surface to transfer heat from the fluid to an airflow passing along the second surface and the thermally sensitive portion is configured to passively position at least a portion of the heat exchanger body into the airflow.
