Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 1, an engine cooling water jacket includes: the engine body water jacket 1 and the cylinder sleeve 2, the engine body water jacket 1 is sleeved outside the cylinder sleeve 2 at intervals.
As shown in fig. 1 and fig. 2, a water inlet 11 is disposed at a lower portion of the body water jacket 1, a water outlet 12 is disposed at an upper portion of the body water jacket 1, the water inlet 11 and the water outlet 12 are respectively located at two opposite sides of the body water jacket 1, two flow guide belts 13 are fixedly disposed on an inner surface of the body water jacket 1 and are axially spaced, the flow guide belts 13 extend along a circumferential direction of the body water jacket 1, and the flow guide belts 13 are annular structures provided with notches 14.
From bottom to top, the notch 14 and the water inlet 11 of the first flow guiding belt 13 are respectively located at two opposite sides of the engine body water jacket 1, and the notch 14 and the water outlet 12 of the second flow guiding belt 13 are respectively located at two opposite sides of the engine body water jacket 1.
The two diversion belts 13 divide the cooling water jacket into three layers of water paths. The cooling water enters the lower-layer waterway from the water inlet 11, then enters the middle-layer waterway from the notch 14 of the first diversion strip 13, then enters the upper-layer waterway from the notch 14 of the second diversion strip 13, and finally flows out from the water outlet 12, and the waterway flow directions of the adjacent layers are opposite.
Fig. 4 is a top view of a water path in a certain layer, and cooling water flows around the cylinder liner 2 in two paths after entering from an inlet, and finally converges to flow to the gap 14 or the water outlet 12.
Because the machine body water jacket 1 is provided with the two flow guide belts 13, the two flow guide belts 13 ensure the flowing direction of the cooling water, so that the cooling water can uniformly cool all parts of the cylinder sleeve 2, and the problem of reliability such as cracks caused by nonuniform cooling of the cylinder sleeve 2 is solved.
