Flow-path controllers and related systems
An observed operational state can include an operational state of one or more system devices. A sensor can emit, in response to a detected observable condition reflective of a given operational state, a simulated signal reflective of a different operational state as a proxy for the detected condition. A controller receiving such a proxy signal can, at least partially responsively to the proxy signal, issue a command corresponding to the given operational state. An electro-mechanical actuator can be selectively activatable responsive to the command.
1. A cooling system, comprising:
a sensor circuit configured to emit a simulated signal corresponding to a selected physical parameter as a proxy for an observed operational parameter different from the selected physical parameter;
a controller configured to receive the simulated signal and to infer a state of the observed operational parameter from the simulated signal, the controller being configured to emit a control signal over a communication connection in response to the inferred a state of the observed operational parameter being within a selected range; and
a branch of a cooling circuit having an inlet, an outlet and a heat exchanger configured to transfer heat to or from a liquid coolant flowing from the inlet, through the heat exchanger and to the outlet, the inlet having a liquid coupler configured to mechanically couple the inlet with a coolant supply, wherein the liquid coupler fluidically couples the inlet to a conduit containing coolant while the liquid coupler is mechanically coupled with the coolant supply and isolates the inlet from the conduit when the liquid coupler is mechanically decoupled from the coolant supply; and
an electro-mechanical actuator communicatively coupled with the controller to receive the control signal over the communication connection, the electro-mechanical actuator configured to mechanically decouple the liquid coupler from the coolant supply responsive to the control signal.
2. The cooling system according to claim 1 , wherein the liquid coupler comprises a retainer movable between a first position and a second position, the retainer being in the first position when the liquid coupler mechanically couples with the coolant supply, wherein the liquid coupler mechanically decouples from the liquid supply when the retainer is in the second position.
3. The cooling system according to claim 2 , wherein the electro-mechanical actuator comprises a control arm movable between a first extent and a second extent responsive to the control signal.
4. The cooling system according to claim 3 , wherein movement of the control arm toward the second extent urges the retainer toward the second position.
5. The cooling system according to claim 1 , wherein the electro-mechanical actuator comprises a servo motor, a stepper motor, or both.
6. The cooling system according to claim 1 , wherein the liquid coupler comprises a biasing member configured to urge the liquid coupler away from the liquid supply, the cooling system further comprising a movable retainer mechanically coupled with the liquid coupler, the retainer being movable between a retention position and a release position, wherein, in the retention position, the retainer causes the liquid coupler to engage with the coolant supply, wherein the biasing member causes the liquid coupler to disengage from the coolant supply when the retainer is in the release position.
7. The cooling system according to claim 6 , further comprising a control arm mechanically coupling the electro-mechanical actuator with the retainer, wherein movement of the control arm from a first extent to a second extent urges the retainer to move from the retention position to the release position.
8. The cooling system according to claim 7 , wherein the electro-mechanical actuator comprises a servo motor, a stepper motor, or both, configured to urge the control arm to move toward the second extent from the first extent.
9. The cooling system according to claim 6 , wherein the electro-mechanical actuator is configured to urge the retainer toward the release position from the retention position.
10. The cooling system according to claim 9 , wherein the electro-mechanical actuator is configured to move the retainer into the release position from the retention position.
11. The cooling system according to claim 10 , wherein movement of the retainer into the release position by the electro-mechanical actuator allows the biasing member to cause the liquid coupler to physically disengage from the coolant supply.
12. The cooling system according to claim 10 , wherein the liquid coupler is configured to automatically disengage from the coolant supply when the electro-mechanical actuator moves the retainer into the release position.
13. The cooling system according to claim 1 , wherein the sensor circuit comprises a leak detection circuit.
