Embodiment Construction
[0044] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0045] The invention provides an engine cooling system, which includes a cylinder water jacket 1 arranged on the cylinder block and a cylinder head water jacket 2 arranged on the cylinder head. The cylinder inner water jacket 11 and the cylinder outer water jacket 12 are arranged in sequence from the outside, and the cylinder head water jacket 2 includes the cylinder head inner water jacket 21 and the cylinder head outer water jacket 22 arranged in sequence from the inside to the outside.
[0046] Wherein, the outer water jacket 22 of the cylinder head communicates with the inner water jacket 11 of the cylinder to form a first cooling passage, and the first cooling passage has a first water inlet and a first water outlet 14; The water jacket 21 in the inner layer of the cover communicates to form a second co...

The invention provides an engine cooling system and a vehicle. The engine cooling system comprises a cylinder body water jacket and a cylinder cover water jacket, wherein the cylinder body water jacket is arranged on a cylinder body, the cylinder cover water jacket is arranged on a cylinder cover, the cylinder body water jacket comprises a cylinder body inner layer water jacket and a cylinder body outer layer water jacket which are sequentially arranged around an engine from the inside to the outside, the cylinder cover water jacket comprises a cylinder cover inner layer water jacket and a cylinder cover outer layer water jacket in sequential arrangement from the inside to the outside, the cylinder cover outer layer water jacket is communicated with the cylinder body inner layer water jacket, a first cooling passage is formed, the first cooling passage is provided with a first water inlet and a first water outlet, the cylinder body outer layer water jacket is communicated with the cylinder cover inner layer water jacket, a second cooling passage is formed, and the second cooling passage is provided with a second water inlet and a second water outlet. The engine cooling system and the vehicle have the advantages that the cooling effect of the engine can be improved, in addition, the heat radiation of the engine can be effectively reduced, and the heat loss of the engine is reduced.
Description
technical field [0001] The invention relates to the technical field of engine cooling, in particular to an engine cooling system and a vehicle. Background technique [0002] The engine cooling system usually pumps coolant into the engine cooling water jacket through a water pump to cool the engine. [0003] The traditional engine cooling water jacket generally includes a cylinder water jacket arranged on the cylinder block and a cylinder head water jacket arranged on the cylinder head. The coolant enters the cylinder water jacket from the coolant inlet on the cylinder block to prevent The components of the cylinder block are cooled, and then the coolant flows from the water jacket of the cylinder block to the water jacket of the cylinder head, and then cools the components on the cylinder head. [0004] However, in this cooling method of the engine, since the coolant cools the cylinder head after cooling the cylinder body, the cooling effect of the cylinder head is not good...
