Shutoff and leak-proof cooling system

Abstract

A leak-stop cooling system includes at least one cooling device, at least two solenoid valves, at least one leak sensor, and a control device. The cooling device includes a cold plate, an inlet pipe, and an outlet pipe. The inlet and outlet pipes are respectively connected to the cold plate, allowing coolant to flow from the inlet pipe through the cold plate to the outlet pipe. The solenoid valves are respectively disposed on the inlet and outlet pipes and switch between an open state and a closed state. In the open state, coolant flow is permitted; in the closed state, coolant flow is blocked. The leak sensor is disposed corresponding to the cooling device and is used to sense leak-related parameters. The control device is communicatively connected to the leak sensor and the solenoid valves, and when a coolant leak is detected based on the leak-related parameters, it sends at least one shut-off control signal to the solenoid valves to cut off the coolant flow and prevent further leakage.

Claims

1. A shut-off and leak-stopping cooling system, comprising: at least one cooling device, including: a cold plate; an inlet pipe connected to the cold plate for a cooling liquid to flow into the cold plate from the inlet pipe; and an outlet pipe connected to the cold plate for the cooling liquid to flow out from the cold plate to the outlet pipe; at least two solenoid valves respectively disposed on the inlet pipe and the outlet pipe, and controlled to switch between an open state and a shut-off state, for allowing the cooling liquid to flow in the inlet pipe and the outlet pipe when in the open state, and for blocking the flow of the cooling liquid in the inlet pipe and the outlet pipe when in the shut-off state; At least one leakage sensor is provided corresponding to the at least one cooling device to sense a leakage-related parameter corresponding to the coolant, wherein the leakage-related parameter is a resistance value; and a control device is communicatively connected to the at least one leakage sensor and the at least two solenoid valves to send a cut-off control signal to the at least two solenoid valves when it is determined based on the leakage-related parameter that the coolant is leaking from the at least one cooling device, thereby causing the at least two solenoid valves to switch from the open state to the cut-off state, thereby cutting off the coolant to prevent further leakage.

2. The shut-off and leak-stopping cooling system as described in claim 1, wherein, The at least two solenoid valves are either normally open or normally closed.

3. The shut-off and leak-stopping cooling system as described in claim 1, wherein, The at least one leakage sensor is one of a leakage sensing cord and a leakage sensing patch.

4. The leak-stopping cooling system as described in claim 1, wherein, The control device is a Baseboard Management Controller (BMC).

5. The shut-off and leak-stopping cooling system as described in claim 1, wherein, The at least one cooling device further includes two liquid connectors, which are respectively located at the other end of the water inlet pipe and the water outlet pipe away from the cold plate.

6. The cut-off and leak-proof cooling system as described in claim 1 further includes an inlet manifold and an outlet manifold, the inlet manifold being connected to the inlet pipe and the outlet manifold being connected to the outlet pipe.
