Technical Field
The invention relates to the technical field of cylinder sleeve cooling, in particular to a cylinder sleeve cooling device capable of accurately shunting.
Background
At present, with the increasing of detonation pressure and power of an engine, a large amount of heat is generated when a high-power engine works, and in order to ensure that each system in an engine cylinder can work and operate reliably and coordinately, a cylinder group of the engine needs to be cooled, particularly, the middle upper part of a cylinder sleeve needs to be cooled.
In the prior art, the combustion starting position in an engine cylinder is near the top dead center of a piston, so that more cooling water is needed at the upper part of a cylinder sleeve. However, most of the annular water jackets formed between the cylinder liners and the cylinder bodies have the same cross-sectional area of the upper and lower channels, and due to the unreasonable shape and position arrangement of the water inlet and outlet, the cooling water is distributed in the middle and lower parts of the cavity too much cooling liquid, so that the sealing structure at the middle and upper part of the cavity, the cylinder body and the cylinder liners cannot be effectively cooled.
In summary, how to provide a device capable of effectively cooling the cylinder body and the cylinder liner at the middle upper part of the cavity is an urgent problem to be solved by those skilled in the art.
