[0002] Water jackets, as a typical basic structural component, are widely used in engine blocks, cylinder heads, gearboxes, and various industrial equipment that require liquid cooling.

[0003] In the existing technology, there exists a type of circular water jacket product with specific requirements. This type of water jacket has a relatively long dimension in the axial direction, forming a relatively long cylindrical structure; at the same time, in order to meet its structural strength and service life requirements in high-pressure and highly corrosive environments, its circumferential sidewalls are designed to be relatively thick.
