Detailed description of the invention
The core of the present invention is to provide a kind of Cooling Water Jacket of Cylinder Head, to improve cylinder head cooling effect.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As Figure 1-Figure 4, disclosing a kind of cylinder head in the present invention, including cooling water cavity, wherein, this cooling water cavity leads to
Cross dividing plate to be divided on upper strata water cavity 1 and lower floor's water cavity 2, and this dividing plate and have for the coolant in lower floor's water cavity 2 being led
Entering the string water hole 41 of upper strata water cavity 1, the coolant in upper strata water cavity 1 can be guided by string water hole 41.Cylinder head is cooled down
Water cavity is divided into upper and lower two-layer, and centre dividing plate separates, and whole current flow through lower floor's water cavity 2, strengthens fire deck cooling effect, simultaneously
Also there is rigidity and the assosting effect of intensity increasing cylinder cap;Cooling water is cooled down from bottom to top by string water hole 41, thus strengthens
Discharge area, strengthens ridge area cooling effect, and can make more to the flow direction of regulation coolant by the guiding in string water hole 41
Coolant flow to need cooling region, improve cooling effect further.
Upper strata water cavity 1 disclosed herein include into-arrange ridge area, enter-enter ridge area and row-row ridge area.At present
Cooling Water Jacket of Cylinder Head, it is impossible to meet cooling needs;Air inlet side current are relatively big, and exhaust side water flow structure is poor, it is impossible to the coldest
But aerofluxus ridge area temperature, and fire check, valve guide bushing temperature are the most high to cause aerofluxus ridge area in cylinder head fire deck to occur
Fault, causes cylinder head to lose efficacy.In view of the above problems, string water hole 41 the most provided herein includes circumferentially dividing
Three of cloth string roads, water hole, and three string roads, water hole include for entering-arrange the first string road, water hole 51 of ridge area cooling, using
In to entering-enter the second string road, water hole 52 of ridge area cooling and the 3rd string road, water hole 53 of row-row ridge area cooling being carried out cold
But.Use the mode in three string roads, water hole to distributing current, make more moisture be fitted on the region needing cooling, thus improve
Cooling effect, can be set according to different needs for the string number in road, water hole and direction, and all in protection domain.
In conjunction with WP5 cylinder head disclosed herein, the 3rd string road, water hole that row-row ridge area is cooled down will be used for
53 and for enter-arrange ridge area cooling first string road, water hole 51 circulation area be set to be all higher than for entering-enter nose
The circulation area in the second string road, water hole 52 of Liang Qu cooling.The size in road, water hole gone here and there for setting to carry out according to cooling requirement
Set, and all in protection domain.
On the basis of technique scheme, the dividing plate in this cylinder head also has and cools down in by lower floor's water cavity 2
Coolant import the auxiliary string water hole 42 of upper strata water cavity 1, to increase discharge area, strengthen the efficiency to cylinder head cooling.Right
May be configured as two in auxiliary string water hole 42, and be arranged on the end of dividing plate, concrete can be positioned opposite, and disclosed above
String water hole 41 is then relative with the ridge area of cylinder head, to strengthen the effect to ridge area cooling.
Additionally, also disclose a kind of cylinder in the application, including cylinder head, this cylinder head is disclosed in above-described embodiment
Cylinder head, therefore, the cylinder with this cylinder head also has above-mentioned all technique effects, and this is no longer going to repeat them.
