the warning message is sent to a liquid cooling controller, so that the liquid cooling controller carries out liquid cooling according to the warning message, and the method comprises the following steps:

and sending the alarm information to the liquid cooling controller so that the liquid cooling controller determines the temperature difference between the temperature of a cooling liquid inlet of the cooling liquid cabinet and the temperature of a cooling liquid outlet, determines the flow rate value of the cooling liquid according to the alarm information and the temperature difference, and adjusts the flow rate of the cooling liquid according to the flow rate value of the cooling liquid so as to carry out liquid cooling on the server.

5. The cooling control method according to claim 2, wherein the cooling the server according to the target process includes:

and when the target process is the first process, closing the air cooling system according to a closing instruction.

6. The cooling control method according to claim 2, wherein the cooling the server according to the target process further includes:

when the target process is the second process, acquiring real-time temperature data of the server;

and controlling an air cooling system to carry out air cooling according to the real-time temperature data.

7. The cooling control method according to any one of claims 1 to 6, wherein the determining the cooling environment in which the server is located based on the first signal includes:

if the first signal is a high level signal, judging that the cooling environment where the server is located is a liquid cooling environment;

and if the first signal is a low level signal, judging that the cooling environment in which the server is located is an air cooling environment.

8. The cooling control device is characterized by comprising an acquisition module, a determination module, a selection module and a cooling module;

the acquisition module is used for acquiring a first signal of the sensor;

the determining module is used for determining the cooling environment in which the server is located according to the first signal;

the selection module is used for selecting a target process for cooling the server according to the cooling environment of the server;

the cooling module is used for cooling the server according to the target process.

9. A controller comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor implementing the cooling control method according to any one of claims 1 to 7 when executing the computer program.

10. A server comprising a sensor and the controller of claim 9;

the sensor is installed on a mainboard of the server and used for identifying a cooling environment of the server.
