Be the cooling water jacket structure of traditional gasoline engine cylinder lid in upright arrangement shown in Fig. 1, wherein, cooling liquid flows into cylinder cap from the upper freight around every cylinder, and the cooling liquid around the first cylinder can flow through the second cylinder, the 3rd cylinder, the 4th cylinder successively, then flows out.And the cooling liquid around the second cylinder also can flow through the 3rd cylinder, the 4th cylinder, then flow out, by that analogy.Therefore, can reduce successively from the first cylinder to the 4th cylinder flow resistance.
Find by analyzing the CFD of this water jacket, from the first cylinder to the 4th cylinder, temperature presents the cylinder head temperature field pattern reduced successively.That is, several years even larger temperature gradient can be there is in the temperature between each cylinder.
The thermal distortion that there is countercylinder lid of temperature gradient has adverse influence, also may there is the risk of pinking.Simultaneously because cooling liquid is longitudinal flow in cylinder cap, can flow through cylinder cap the most complicated all inner section, this makes the cooling liquid of head part there will be the larger pressure loss.
For the cooling water jacket structure of tradition gasoline engine cylinder lid in upright arrangement, the cooling uniformity of each cylinder be improved, can only by the upper water hole area of each cylinder of adjustment.Upper water hole area below first and second cylinder of artificial increase, reduces the upper water hole area below third and fourth cylinder.Thus increase the flow resistance of cooling liquid around third and fourth cylinder, reduce the flow resistance of cooling liquid around first and second cylinder.
But as can be seen from the CFD in-line analysis of this water jacket, such jacket structure for water flow path is very complicated.Thus the area going up freight needs through adjustment repeatedly, analyzes and can produce a desired effect.Meanwhile, such structure change, will certainly increase the overall flow resistance of cylinder head water jacket, causes larger integral pressure loss.
Therefore, a kind of novel cylinder head cooling jacket of necessary exploitation, overcomes defect of the prior art.
Model utility content
The purpose of this utility model is to provide a kind of cylinder head cooling jacket, and its structure is simple, optimizes easily; Cylinder head can be made effectively to be cooled in the course of the work; The uniformity of temperature profile between each cylinder of cylinder head can also be ensured simultaneously as far as possible.
To achieve these goals, the technical solution adopted in the utility model is as follows.
A kind of cylinder head cooling jacket, it comprises the upper strata water jacket and lower floor's water jacket that are interconnected, after wherein engine coolant all upwards flows into the air inlet side water jacket of cylinder cap from the air inlet side water jacket of cylinder body, be divided into via upper and lower layer water jacket respectively and upper and lowerly two-layerly all laterally flow to exhaust side, flow out after the water outlet above gas exhaust manifold collects.
Further, wherein said upper strata water jacket and lower layer of water are enclosed within exhaust flange face by supporting UNICOM.
Further, wherein said lower floor water jacket comprises freight, is arranged on the both sides of intake duct.
Further, wherein said upper water cover directly flows to water outlet after around spark-plug hole above gas exhaust manifold.
Further, the intake duct both sides that every cylinder walked around by wherein said lower floor water jacket flow to cylinder cover chamber end face, flow to below gas exhaust manifold around the ridge area and cylinder bolt hole of every cylinder respectively again, the ring-shaped water jacket eventually passing exhaust flange face is pooled to the water outlet above gas exhaust manifold.
Further, the joint of wherein said upper strata water jacket and described lower floor water jacket is provided with technique pressure head.
The utility model also provides following technological scheme: a kind of motor, and wherein, it includes the cylinder head cooling jacket as described in one or more in technique scheme.
Relative to prior art, the beneficial effects of the utility model are: the utility model adopts novel cross-flow type cylinder head cooling jacket, is divided into upper and lower two-layer design, makes the streamline of cooling liquid very clear, controlled.From two of every cylinder air inlet side, water hole flows into, and laterally flows to exhaust side.Except external factor, there is not influencing each other between each cylinder in water jacket itself completely, so to ensure the uniform temperature fields distribution of each cylinder.

Embodiment
Below with reference to drawings and Examples, a kind of cylinder head cooling jacket technological scheme that the utility model relates to is described in further detail.
Refer to shown in Fig. 2, a kind of cylinder head cooling jacket that the mode of execution that the utility model relates to provides, it designs for cross-flow type, comprises upper strata water jacket 10 and lower floor's water jacket 20, point upper and lower two-layer design.
Refer to shown in Fig. 3, lower floor's water jacket 20 of the utility model cross-flow type cylinder head cooling jacket, it devises freight 22 on 6 in air inlet side.Two, every cylinder, is arranged in intake duct both sides.And other water jacket pin are technique and fall husky pin, in the casting cycle of cylinder head, play the effect that water jacket supports simultaneously.
At the top of combustion chamber of every cylinder, around spark-plug hole, the average thickness of water jacket controls at about 7mm, and to guarantee in cylinder head working procedure, chamber wall and spark plug hole wall are effectively cooled.
The ridge area 24 of the every cylinder exhaust side shown in Fig. 3, in it, the flow velocity of cooling liquid is the important indicator weighing cylinder head cooling jacket flow condition, usually must be not less than 2m/s.Therefore, under the prerequisite meeting the husky core molding process requirement of water jacket and the wall thickness requirement of cylinder cap own.The sectional area in region, ridge area 24 to be increased as far as possible, flow to ridge area to allow more cooling liquid.
