Engine cooling system, control method thereof and vehicle

The invention provides an engine cooling system, a control method thereof and a vehicle. The engine cooling system comprises an air cylinder, a first water inlet pipe, a first water outlet pipe and a second water outlet pipe, the air cylinder comprises an air cylinder body, an inlet of the first water inlet pipe is used for receiving cooling liquid for cooling the air cylinder body, and an outlet of the first water inlet pipe is connected with the air cylinder body; the first water outlet pipe is arranged on the upper half section of the cylinder body, the second water outlet pipe is arranged on the lower half section of the cylinder body, and the first water inlet pipe is communicated with the first water outlet pipe and the second water outlet pipe and located in the cylinder body. According to the technical scheme, the situation of uneven upper and lower thermal deformation of the air cylinder body can be reduced, air leakage is reduced, and therefore stable output power of an engine is guaranteed. 本申请提供了一
