Passive Cooling System for Control Valve Actuators |
| 摘要 |
The present application provides a passive control valve actuator cooling system to provide a flow of cooling air to a control valve actuator used with a gas turbine engine. The passive control valve actuator cooling system may include a turbine enclosure with a negative pressure therein, a radiation shield with a number of radiation shield outlets and the control valve actuator positioned therein, and a cooling air line extending from outside of the turbine enclosure to the radiation shield such that the negative pressure within the turbine enclosure pulls the flow of cooling air into and through the radiation shield so as to cool the control valve actuator. |

1. A passive control valve actuator cooling system to provide a flow of cooling air to a control valve actuator used with a gas turbine engine, comprising:
a turbine enclosure; the turbine enclosure comprising a negative pressure therein; a radiation shield with the control valve actuator positioned therein; the radiation shield comprising a plurality of radiation shield outlets; and a cooling air line extending from outside of the turbine enclosure to the radiation shield such that the negative pressure within the turbine enclosure pulls the flow of cooling air into and through the radiation shield so as to cool the control valve actuator. |
