Specific embodiment
Core of the invention is to provide a kind of cylinder head, and cooling water cavity is to improve cylinder head cooling effect.The present invention is also
Provide a kind of cylinder with above-mentioned cylinder head.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As Figure 1-Figure 5, a kind of cylinder head, including cooling water cavity are disclosed in the present invention, wherein the cooling water cavity is logical
It crosses partition and is divided into upper layer water cavity 1 and lower layer's water cavity 2, and have on the partition for leading the coolant liquid in lower layer's water cavity 2
Enter the string water hole 41 of upper layer water cavity 1, string water hole 41 can be oriented to the coolant liquid in upper layer water cavity 1, in lower layer's water cavity 2
Exhaust side bottom plate has collecting tray 6.Cooling Water Jacket of Cylinder Head is divided into upper layer and lower layer, centre is separated with partition, whole water flow streams
Lower layer's water cavity 2 is crossed, reinforces fire deck cooling effect, while also there is the booster action for the stiffness and strength for increasing cylinder cap；It is cooling
Water is cooled down from bottom to top by string water hole 41, to increase discharge area, reinforces ridge area cooling effect, and pass through string water hole
41 guiding can make more coolant liquid flow directions need cooling region, further increase cooling to the flow direction for adjusting coolant liquid
Effect.The collecting tray 6 of exhaust side can improve the cooling situation of exhaust side further to further increase cooling in lower layer's water cavity 2
Effect.
Specifically, the collecting tray 6 has confluence face and guide face, wherein guide face is used for the flowing to coolant liquid and carries out
Water conservancy diversion, and face of converging then is used to converge to coolant liquid, prevents the coolant liquid flowed into collecting tray 6 from flowing out under inertial flow
Collecting tray 6, therefore, the tilt angle of guide face are less than the tilt angle in confluence face.For the inclination angle of guide face and confluence face
Degree can be set according to different needs, and in protection scope.
The ridge area of cylinder head disclosed herein include into-row ridge area, into-into ridge area and row-row ridge area.
Current Cooling Water Jacket of Cylinder Head, is unable to satisfy cooling requirement；Air inlet side water flow is larger, and exhaust side water flow structure is poor, Bu Nengyou
The cooling exhaust ridge area temperature of effect, and exhaust ridge area in cylinder head fire deck is caused fire check, valve guide bushing temperature mistake occur
High failure, causes cylinder head to fail.In view of the above problems, string water hole 41 provided herein as shown in Figure 4 includes along week
To three string water hole roads of distribution, and three string water hole roads include for into-the first cooling string water hole road of row ridge area
51, for into-into the second cooling string water hole road 52 of ridge area and to the cooling third string water hole road 53 in row-row ridge area into
Row cooling.To water flow is distributed by the way of three string water hole roads, it is fitted on more moisture and needs cooling region, thus
Cooling effect is improved, the number and direction in string water hole road can be set according to different, and in protection scope
It is interior.
In addition, the coolant liquid that collecting tray 6 converges is set as cooling down row-row ridge area, can will specifically converge
Slot 6 is set up directly in row-row's nasal bridge region, either with the row-row's nasal bridge region face or back to being converged by collecting tray 6
The coolant liquid of stream can guarantee that the coolant liquid in collecting tray 6 at any time cools down the region, extends cooling time, improves cold
But effect.
In conjunction with WP5 cylinder head disclosed herein, will be used to carry out row-row ridge area in cooling third string water hole road
53 and for the circulation area into-the first cooling string water hole road 51 of row ridge area be set as being all larger than for into-into nose
The circulation area in the second Liang Qu cooling string water hole road 52.The size in the string water hole road of setting can be carried out according to cooling requirement
Setting, and in protection scope.
Based on the above technical solution, also have on the partition in the cylinder head for that will be cooled down in lower layer's water cavity 2
Coolant liquid import the auxiliary string water hole 42 of upper layer water cavity 1 and reinforce the efficiency cooling to cylinder head to increase discharge area.It is right
It may be configured as two in auxiliary string water hole 42, and the end of partition be set, specifically can be positioned opposite, and it is disclosed above
String water hole 41 is then opposite with the ridge area of cylinder head, to reinforce the effect cooling to ridge area.
In addition, also disclosing a kind of cylinder in the application, including cylinder is somebody's turn to do, which is disclosed in above-described embodiment
Cylinder head, therefore, the cylinder with the cylinder head also have above-mentioned all technical effects, and this is no longer going to repeat them.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
