[0002] The intelligent flow regulating device for liquid cooling joints is a device used in liquid cooling systems to control the flow rate and temperature of liquid in the system to ensure stable operation.

[0003] Liquid cooling technology is widely used in data centers, power electronic equipment, new energy vehicles, and other fields, achieving efficient heat dissipation through liquid circulation. However, traditional liquid cooling connectors often employ fixed flow designs or manually adjustable valves, which present the following problems:

[0004] 1) Lagging flow regulation: The flow rate cannot be dynamically adjusted according to the real-time temperature, resulting in insufficient heat dissipation or energy waste;

[0005] 2) Reliance on manual intervention: The valve body needs to be manually adjusted, which is difficult to adapt to complex operating conditions. Therefore, we propose an intelligent flow regulation device for liquid-cooled connectors. Utility Model Content

[0017] As an improved technical solution, the data interface supports RS485, CAN bus or wireless transmission protocols, and can report flow rate, temperature and fault codes.

[0018] As an improved technical solution, a pressure sensor is also included. The pressure sensor is disposed in the coolant flow channel and is electrically connected to the flow controller. The pressure sensor is used to monitor the pressure difference and feed it back to the flow controller for leakage early warning.

[0019] As an improved technical solution, the flow controller integrates a low-power mode, which can shut off the power supply to the stepper motor when the temperature difference is below a threshold.

Temperature sensor group 2 is a high-precision thermocouple sensor or fiber optic temperature sensor with a sampling frequency ≥10Hz. The use of high-precision thermocouple or fiber optic temperature sensor (sampling frequency ≥10Hz) ensures millisecond-level temperature feedback. In application, the temperature difference is monitored in real time by temperature sensor group 2 at the inlet 101 and outlet 102 of the flow channel. Combined with the PID algorithm of the flow controller 4, the needle valve opening can be dynamically adjusted to achieve accurate matching between flow rate and heat dissipation requirements.

In application, the temperature sensor group 2, together with the needle valve driven by the stepper motor, can effectively suppress temperature fluctuations.

[0038] The flow controller 4 is mounted on a fixed frame and is electrically connected to the temperature sensor group 2 and the stepper motor. The flow controller 4 dynamically calculates the target flow rate and adjusts the needle valve opening based on the temperature difference. The flow controller 4 is a dedicated flow control IC with a built-in PID algorithm, which can adjust the flow rate in advance based on historical temperature rise trends. At the same time, it can reduce power consumption through hardware-level optimization. The flow controller 4 integrates a low-power mode, which can turn off the power supply to the stepper motor when the temperature difference is below the threshold.

[0039] Data interface 5 is located on the flow controller 4. Data interface 5 is used to communicate with external systems. Data interface 5 supports RS485, CAN bus or wireless transmission protocols and can report flow, temperature and fault codes. In application, data interface 5 can be connected to the intelligent temperature control network to remotely monitor flow, temperature and operating status, realize multi-node collaborative control and reduce manual inspection costs.
