Abstract

The invention relates to a liquid cooling dynamic regulation control method, system and device with load feedback, and belongs to the technical field of liquid cooling distribution. Comprising the following steps: S1, acquiring inlet and outlet liquid temperature and real-time power consumption data of each to-be-cooled device in real time; s2, the inlet and outlet liquid temperature of each device is compared with a safe temperature threshold value, and the rotating speed of a water pump on the secondary side is dynamically adjusted according to the comparison result; when the inlet and outlet liquid temperature is close to the safe temperature threshold value, the heat dissipating capacity of each device is calculated according to the inlet and outlet liquid temperature and the real-time power consumption data; adjusting the rotating speed of the water pump according to the heat dissipating capacity; wherein when the S1 is executed, a fluid channel, used for heat exchange of the secondary side, in the primary side is set to be at the fixed opening degree, and the water temperature of the primary side is obtained in real time; and when it is detected that the water temperature of the primary side is abnormal or breaks down, the state of the fluid channel is automatically switched to the bypass mode. Dynamic adjustment of the rotating speed of the water pump is achieved, dependence on the total liquid return temperature is not needed, the cooling efficiency is improved, and energy consumption is reduced.
