AI Technical Summary

Technical Problem

Current technology cannot accurately determine the water flow status of liquid-cooled cabinets, which may cause servers to overheat and be damaged due to insufficient flow, affecting the normal operation of the data center.

Method used

A water flow detection device for a liquid-cooled server rack is designed. By forming a detection branch in parallel with the liquid cooling system, the resistance of the detection pipeline is adjusted to match the operating resistance of the server branch using a resistance adjustment component, thereby achieving accurate flow detection.

Benefits of technology

It enables accurate detection of the actual flow rate when water is supplied to the server rack, avoiding server overheating alarms and damage caused by misjudging the water supply status, and improving the safety and reliability of the liquid cooling system.

Abstract

This utility model provides a water flow detection device for a liquid-cooled server rack, relating to the field of liquid cooling technology. The liquid-cooled server rack includes a server and a liquid cooling system for cooling the server. The water flow detection device includes a detection pipeline, a flow detection component, and a resistance adjustment component. The detection pipeline is detachably connected to the supply and return pipes of the liquid cooling system to form a detection branch in parallel with the liquid cooling system. The flow detection component is installed in the detection pipeline to detect the flow rate of the coolant passing through it. The resistance adjustment component is installed in the detection pipeline to adjust the flow resistance of the detection pipeline. The resistance adjustment component is used to adjust the resistance of the detection pipeline to match the operating resistance of the server branch in the liquid cooling system, thereby achieving accurate detection of the actual flow rate when the server rack is filled with water, solving the technical problem in the prior art that it is impossible to accurately determine the true water flow status of the server rack.
