Abstract
An underwater assembly includes a flow control device and an actuator coupled to the flow control device, where the actuator is configured to actuate the flow control device. The underwater assembly further includes an insulated housing surrounding the flow control device and the actuator, where the insulated housing is configured to retain heat. The underwater assembly also includes a thermal control system comprising a heat exchanger configured to control a temperature of the actuator.
Claims20
A system, comprising:
- an underwater assembly, comprising:
- a flow control device:
- and
- an actuator coupled to the flow control device, wherein the actuator is configured to actuate the flow control device;
- an insulated housing surrounding the flow control device and the actuator, wherein the insulated housing is configured to retain heat;
- and
- a thermal control system comprising a heat exchanger configured to control a temperature of the actuator.
4 more elements
A system, comprising:
- an underwater thermal control system, comprising:
- a heat exchanger configured to control a temperature of an actuator disposed in an insulated housing;
- an inlet passage configured to pass a water flow from an exterior of the insulated housing into the heat exchanger;
- an outlet passage couple configured to pass the water flow from the heat exchanger to the exterior of the insulated housing;
- and
- a valve coupled to the outlet passage, wherein the valve is configured to open and close to control circulation of the water flow through the inlet passage, the heat exchanger, and the outlet passage based on temperature feedback.
3 more elements
A method, comprising:
- sensing a temperature at or above an upper threshold temperature within an insulated underwater housing that contains an actuator coupled to a flow control device;
- initiating a flow of water from a surrounding water through a heat exchanger within the insulated underwater housing if the temperature is at or above the upper threshold temperature;
- sensing the temperature at or below a lower threshold temperature within the insulated underwater housing;
- and
- terminating the flow of water through the heat exchanger if the temperature is at or below the lower threshold temperature.
