Wherein, the computing device 11 operates in the optimal operating state in the current operating mode, including: the average calculation force value of each computing device 11 of the liquid cooling cabinet 100 in the calculation force optimizing mode reaches the first preset target value. When the liquid-cooled cabinet 100 is in the optimal computing power mode, the average computing power of each computing device 11 in the liquid-cooled cabinet 100 reaches the maximum value on the premise that the overload and the over-temperature are not generated.
Since the actual calculated force value of the computing device 11 is related to the operating temperature of the computing device 11, generally speaking, the highest calculated force value is actually achieved when the computing device 11 is at an optimal operating temperature, which in turn is related to the incoming water flow rate, generally speaking, the greater the incoming water flow rate, the better the cooling of the computing device 11, and the lower the operating temperature.

Wherein, the computing device 11 operates in the optimal operating state in the current operating mode, including: the outlet water temperature of the liquid cooling cabinet 100 in the hot water optimal mode reaches the second preset target value. When the liquid-cooled cabinet 100 is in the hot water optimal mode, the outlet water temperature of the total water outlet 13 of the liquid-cooled cabinet 100 reaches a maximum value on the premise that each computing device 11 is not overloaded and overheated.
Because a certain complex mathematical relationship exists between the water outlet temperature and the force calculation value, the input power, the water inlet temperature, the environment temperature and the water inlet flow, a second mathematical relationship model between the water outlet temperature and the force calculation value, the input power, the water inlet temperature, the environment temperature and the water inlet flow can be obtained through pre-experiments and calculation. Furthermore, the main control unit 23 calculates a second target inflow according to the calculation value, the input power, the inflow temperature, the ambient temperature, the second preset target value, and the first mathematical relationship model to obtain a second target inflow, and controls the water pump 21 to make the current inflow of the liquid cooling cabinet 100 reach the second target inflow, so that the outflow temperature of the total water outlet 13 of the liquid cooling cabinet 100 reaches the second preset target value, that is, the outflow temperature of the total water outlet 13 of the liquid cooling cabinet 100 reaches a maximum value on the premise that the respective computing devices 11 are not overloaded and over-heated.
In some embodiments, the main control unit 23 is further configured to control the water pump 21 to increase the water flow of the output cold water when the parameter value of at least one parameter of the related parameters of the liquid-cooling cabinet 100 collected by the parameter obtaining unit 22 is abnormal.
The inlet flow rate and the relevant parameters of the liquid-cooled cabinet 100 have a complex mathematical relationship, which may be obtained through preliminary experiments or calculations. And then when the acquired parameter value of at least one parameter in the related parameters of the liquid cooling cabinet 100 is abnormal, the inflow rate of water can be increased so that the abnormal value in the related parameters of the liquid cooling cabinet 100 can be recovered to be normal.
