[0028] It should be noted that, in the present application, the control method of the liquid-cooled air-conditioning device includes: when the liquid-cooled air-conditioning device operates normally and the judgment condition meets the preset condition, the control module 50 of the liquid-cooled air-conditioning device controls the heating structure 30 on the heat exchanger 10 to be energized; when the liquid-cooled air-conditioning device operates normally and the judgment condition does not meet the preset condition, the control module 50 controls the heating structure 30 to be de-energized; when the liquid-cooled air-conditioning device cannot operate normally due to a fault, the solenoid valve 40 of the liquid-cooled air-conditioning device loses power and is in an open state to connect the drain pipe 13 of the heat exchanger 10 and the liquid inlet of the liquid storage module 20, so that the coolant in the heat exchange tube 11 is discharged into the liquid storage cavity of the liquid storage module 20; when the liquid-cooled air-conditioning device eliminates the fault, the solenoid valve 40 is energized and is in a closed state to disconnect the drain pipe 13 and the liquid inlet, and the coolant in the liquid storage cavity flows back to the heat exchange tube 11 through the liquid replenishing port and the liquid inlet pipe 12 of the liquid storage module 20.

[0029] It should be noted that, in the present application, the judgment condition that meets the preset condition includes that the flow value of the coolant in the heat exchange tube 11 is 0, and the temperature value of the coolant in the heat exchange tube 11 is lower than 1°C; the judgment condition that does not meet the preset condition includes that the flow value of the coolant in the heat exchange tube 11 is not 0, and the temperature value of the coolant in the heat exchange tube 11 is not lower than 1°C.

[0030] like Figures 1 to 3 As shown, the liquid-cooled air-conditioning device includes a heat exchanger 10, a liquid storage module 20, a heating structure 30, a solenoid valve 40 and a control module 50, wherein the heat exchanger 10 has a heat exchange tube 11 and a liquid inlet tube 12 and a liquid discharge tube 13 connected to the heat exchange tube 11; the liquid storage module 20 has a liquid storage cavity and a liquid inlet and a liquid replenishing port connected to the liquid storage cavity, the liquid inlet is connected to the liquid discharge tube 13, and the liquid replenishing port is connected to the liquid inlet tube 12; the heating structure 30 is arranged on the heat exchange tube 11 to heat the coolant in the heat exchange tube 11 to prevent the coolant in the heat exchange tube 11 from freezing; the solenoid valve 40 is arranged on the liquid discharge tube 13 to control the on and off of the liquid discharge tube 13 and the liquid inlet; the control module 50 is control-connected to the heating structure 30 to control the power on and off of the heating structure 30 according to the judgment conditions.

[0031] By applying the technical solution of the present invention, a liquid cooling air conditioning device is provided, comprising a heat exchanger 10, a liquid storage module 20, a heating structure 30, a solenoid valve 40 and a control module 50, wherein the heat exchanger 10 has a heat exchange tube 11 and a liquid inlet tube 12 and a liquid discharge tube 13 connected to the heat exchange tube 11; the liquid storage module 20 has a liquid storage cavity and a liquid inlet and a liquid replenishing port connected to the liquid storage cavity, the liquid inlet is connected to the liquid discharge tube 13, and the liquid replenishing port is connected to the liquid inlet tube 12; the heating structure 30 is arranged on the heat exchange tube 11 to heat the coolant in the heat exchange tube 11 to prevent the coolant in the heat exchange tube 11 from freezing; the solenoid valve 40 is arranged on the liquid discharge tube 13 to control the on-off of the liquid discharge tube 13 and the liquid inlet; the control module 50 is control-connected to the heating structure 30, It is used to control the power on and off of the heating structure 30 according to the judgment conditions; wherein, when the liquid-cooled air-conditioning device operates normally and the judgment conditions meet the preset conditions, the control module 50 controls the heating structure 30 to be powered on; when the liquid-cooled air-conditioning device operates normally and the judgment conditions do not meet the preset conditions, the control module 50 controls the heating structure 30 to be powered off; when the liquid-cooled air-conditioning device cannot operate normally due to a fault, the solenoid valve 40 loses power and is in an open state to connect the drain pipe 13 and the liquid inlet so that the coolant in the heat exchange tube 11 is discharged into the liquid storage chamber; when the liquid-cooled air-conditioning device eliminates the fault, the solenoid valve 40 is powered and is in a closed state to disconnect the drain pipe 13 and the liquid inlet, and the coolant in the liquid storage chamber flows back to the heat exchange tube 11 through the liquid replenishing port and the liquid inlet pipe 12.

[0032] By arranging the heating structure 30 on the heat exchange tube 11, the heating structure 30 can heat the coolant in the heat exchange tube 11 to prevent the coolant in the heat exchange tube 11 from freezing, thereby effectively preventing the heat exchange tube 11 from freezing and cracking. In addition, the present application also arranges a solenoid valve 40 on the drain pipe 13. The arrangement of the solenoid valve 40 facilitates the control of the on-off of the drain pipe 13 and the liquid inlet. Specifically, when the liquid-cooled air-conditioning device cannot operate normally due to a malfunction, the solenoid valve 40 loses power and is in an open state, thereby achieving the purpose of connecting the drain pipe 13 and the liquid inlet, thereby allowing the coolant in the heat exchange tube 11 to be discharged into the liquid storage chamber of the liquid storage module 20, which is also beneficial to prevent the heat exchange tube 11 from freezing and cracking in cold weather due to a malfunction of the liquid-cooled air-conditioning device. Furthermore, after the maintenance personnel eliminate the fault, the solenoid valve 40 is energized and in a closed state to disconnect the drain pipe 13 and the liquid inlet, and the coolant in the liquid storage chamber flows back into the heat exchange tube 11 through the liquid replenishing port and the liquid inlet pipe 12.

[0033] It should be noted that, in the present application, the solenoid valve 40 is located at the lowest position of the drain pipe 13 to drain the coolant in the drain pipe 13.

[0039] It should be noted that the heat exchange tube 11 in the present application is a finned copper tube structure.

[0040] like Figure 3 As shown, the heating structure 30 is located on the inner fin of the middle tube section of the heat exchange tube 11.
