Abstract
A heat exchanger system for an aircraft comprises nacelle having an inlet and an outlet, a nacelle heat exchanger within the nacelle, and a fan system within the nacelle. Air flows into the nacelle through the inlet and out of the nacelle through the outlet. The nacelle heat exchanger is configured to transfer heat away from a coolant using the air in an airflow to the nacelle heat exchanger. The fan system is configured to increase the airflow to the nacelle heat exchanger.
Claims27
A heat exchanger system for an aircraft comprising:
- a nacelle having an inlet and an outlet, wherein air flows into the nacelle though the inlet and out of the nacelle through the outlet;
- a nacelle heat exchanger within the nacelle, wherein the nacelle heat exchanger is configured to transfer heat away from a coolant using the air in an airflow to the nacelle heat exchanger;
- and
- a fan system within the nacelle, wherein the fan system is configured to increase the airflow to the nacelle heat exchanger.
A heat exchanger system for an aircraft comprising:
- a nacelle having an inlet and an outlet, wherein air flowing into the nacelle though the inlet and out of the nacelle through the outlet;
- and
- a nacelle heat exchanger within the nacelle, wherein the nacelle heat exchanger is configured to transfer heat away from the air in an airflow to the nacelle heat exchanger, wherein the nacelle heat exchanger is oriented substantially parallel to a direction of flight of the aircraft.
An aircraft comprising:
- a fuselage;
- a first wing and a second wing connected to the fuselage;
- engines connected to the first wing and the second wing, wherein each engine in the engines comprises:
- a nacelle;
- an electric motor within the nacelle;
- a fuel cell stack within the nacelle;
- and
- a nacelle heat exchanger within the nacelle, wherein the nacelle heat exchanger is configured to transfer heat away from a coolant using air in an airflow to the nacelle heat exchanger;
- and
- a fan system within the nacelle, wherein the fan system is configured to increase the airflow to the nacelle heat exchanger.
