AI Technical Summary
In the testing process of existing liquid cooling systems, the processes of liquid injection, pressure holding, flushing and draining require multiple independent devices to operate in stages, resulting in complicated processes, large operational errors and low efficiency, making it difficult to meet the high efficiency and reliability requirements of large-scale deployment.
By adopting a parallel configuration of the main pump and auxiliary pump, combined with a fluid control unit, pressure detection unit and controller, the liquid cooling system achieves high efficiency, precision and automation of liquid injection and pressure holding cycle. The main pump injects liquid at a large flow rate and the auxiliary pump is finely adjusted at a small flow rate to ensure pressure accuracy and system sealing.
It improves the testing efficiency and sealing reliability of the liquid cooling system, reduces operational errors, and enables precise control of the injection pressure and automated operation of the system.
