Abstract
The utility model discloses a cylinder cover with a cooling water jacket, which comprises a cooling water jacket of the cylinder cover, which is arranged around an oil sprayer installing hole, a water inlet and a water outlet, and is characterized in that the cooling water jacket is arranged in two layers (an upper layer and a lower layer), wherein the upper layer comprises an exhaust side upper water jacket and an inlet side upper water jacket which are communicated with each other, and the lower layer comprises an inlet side lower water jacket and an exhaust side lower water jacket which are communicated with each other, and the upper layer and the lower layer of the cooling water jacket are communicated from up to down in a bridge area; and the water inlet is arranged above the exhaust manifold of the exhaust side of the cylinder cover. Since the cooling water jacket which is arranged in two layers is adopted, and the cross-section area of the bridge area outside the oil sprayer contracts, the flow rate of the cooling fluid is fast, thus realizing the accelerated cooling of the bridge area, reducing the temperature difference of the fireboard of the bridge area of the cylinder cover, and preventing the bridge area of the cylinder cover from heat cracking.
Description
Technical field
The utility model relates to a kind of engine-cooling system, particularly relates to the cylinder cap that a kind of motor has double-deck cooling jacket.
Background technique
As everyone knows, the cooling jacket of cylinder cap is arranged and is directly affected the cooling effect of cooling water to cylinder cap.Reasonably cooling scheme not only can effectively reduce the cylinder cap temperature, can reduce discharging simultaneously.
In the past, the engine cooling mode was the flow through water jacket of cylinder body of cooling liquid, flowed into the water jacket of cylinder caps again through some apertures of cylinder pad, and the water jacket of cylinder cap generally is whole, and it is two-layer to make no distinction of rank.Therefore, cooling water enters cylinder cap from air inlet side or exhaust side exactly, and whole cylinder cap is cooled off.Deficiency is not cool off at the cylinder cap bridge of the nose district between intake valve and the exhaust valve.As shown in Figure 1, cooling water rises by cylinder cap water intake 1 and enters cylinder cap air inlet side cooling jacket 2, around crossing mounting hole of oil sprayer 4, enters exhaust side cooling jacket 3, and then whole cylinder cap is cooled off then.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the existing cylinder cap to provide a kind of cylinder cap that has cooling jacket.Not only can effectively reduce the cylinder cap temperature, prevent the hot tearing in cylinder cap bridge of the nose district, and simple in structure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of cylinder cap that has cooling jacket comprises around the cylinder head cooling water cover of mounting hole of oil sprayer and water intake, water outlet.It is characterized in that: described cooling jacket is divided into two-layer setting up and down, and the upper strata is respectively exhaust side upper water sleeve, the air inlet side upper water sleeve that is communicated with.Lower floor is respectively air inlet side lower water jacket, the exhaust side lower water jacket that is communicated with.The two-layer up and down of cooling jacket is communicated with from top to bottom in bridge of the nose district.
For the better cooling water that distributes, described water intake is arranged in the gas exhaust manifold top of cylinder cap exhaust side.
For better cooling bridge of the nose district, described bridge of the nose district width of flow path value 5-6mm.
Good effect of the present utility model: be divided into the cooling jacket of two-layer setting up and down owing to adopt, owing to the bridge of the nose district reduced cross-sectional outside the oil sprayer, cooling liquid speed is accelerated in bridge of the nose district, thereby accelerates the cooling in bridge of the nose district, reduce the temperature difference of cylinder cap bridge of the nose district fire deck, prevent the hot tearing in cylinder cap bridge of the nose district.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 analyses and observe organigram for existing cylinder cap.
Fig. 2 analyses and observe organigram for the utility model.
Among the figure: 1. cooling liquid water intake, 2. exhaust side upper water sleeve, 3. air inlet side upper water sleeve, 4. mounting hole of oil sprayer, 5. bridge of the nose district, 6. air inlet side lower water jacket, 7. exhaust side lower water jacket, 8. cooling liquid water outlet.
Embodiment
As shown in Figure 2, a kind of cylinder cap that has cooling jacket comprises around the cylinder head cooling water of mounting hole of oil sprayer 4 cover and water intake 1, water outlet 8.Described cooling jacket is divided into two-layer setting up and down, and the upper strata is respectively exhaust side upper water sleeve 2, the air inlet side upper water sleeve 3 that is communicated with; Lower floor is respectively air inlet side lower water jacket 6, the exhaust side lower water jacket 7 that is communicated with; The two-layer up and down of cooling jacket is communicated with from top to bottom in bridge of the nose district 5.
Described water intake 1 is arranged in the gas exhaust manifold top of cylinder cap exhaust side.
Described bridge of the nose district width of flow path value 5-6mm.
Working procedure of the present utility model is, cooling liquid enters exhaust side upper water sleeve 2 from cooling liquid water intake 1 position earlier, cooling water enters air inlet side upper water sleeve 3 by oil sprayer then, is entering inlet and outlet road lower water jacket 6,7 through bridge of the nose district 5 at last, cooling cylinder cap bridge of the nose district and cylinder head plate.Because bridge of the nose district 5 reduced cross-sectional that oil sprayer is outer, cooling liquid speed is accelerated, thereby accelerates the cooling in bridge of the nose district, reduces the temperature difference of cylinder cap bridge of the nose district 5 fire deck, prevents the hot tearing in cylinder cap bridge of the nose district.
Claims (3)
1, a kind of cylinder cap that has cooling jacket, comprise around the cylinder head cooling water of mounting hole of oil sprayer (4) cover and water intake (1), water outlet (8), it is characterized in that: described cooling jacket is divided into two-layer setting up and down, the upper strata is respectively exhaust side upper water sleeve (2), the air inlet side upper water sleeve (3) that is communicated with, and lower floor is respectively air inlet side lower water jacket (6), the exhaust side lower water jacket (7) that is communicated with; The two-layer up and down of cooling jacket is communicated with from top to bottom in bridge of the nose district (5).
2, cylinder cap according to claim 1 is characterized in that: described water intake (1) is arranged in the gas exhaust manifold top of cylinder cap exhaust side.
