Description

A kind of novel cylinder cover water jacket

Technical field

The utility model belongs to engine-cooling system technical field, more particularly, to a kind of novel cylinder cover water jacket.

Background technique

Conventional engines cylinder head, exhaust manifold independent design, cylinder head use integral water jacket structure, to combustion chamber, The positions such as exhaust duct are cooled down；Exhaust manifold is assembled in cylinder head, and cylinder cover water jacket can not cool down exhaust manifold, only It can be thermally shielded using heat shield, cooling effect is poor, and exhaust manifold is also easy to produce crackle.

Utility model content

For overcome the deficiencies in the prior art, it is strong to provide a kind of exhaust manifold cooling capacity for the utility model, is not likely to produce The novel cylinder cover water jacket of crackle.

To achieve the goals above, the utility model uses following technical scheme：A kind of novel cylinder cover water jacket, including gas Cylinder cap ontology, cylinder head jacket and the exhaust manifold on the cylinder head ontology, the cylinder head jacket include upper water Set and lower layer's water jacket, be equipped in the exhaust manifold upper water sleeve being connected with the upper layer water jacket and with lower layer's water jacket phase The lower water jacket of connection, the exhaust manifold two sides are respectively equipped with the exhalant canal for being connected to the upper water sleeve and lower water jacket.This is practical It is novel by the way that the upper and lower water jacket that is connected with cylinder head entirety water jacket is arranged in exhaust manifold, accelerate the cold of exhaust manifold But speed improves the cooling capacity of exhaust manifold, effectively prevents the case where exhaust manifold is cracked because of overheat, And the exhalant canal for being connected to the upper water sleeve and lower water jacket is respectively set in exhaust manifold two sides, in the exhaust manifold between each cylinder Upper and lower water jacket will not influence each other, be conducive to guarantee that each cylinder temperature is uniform.

Further, the exhaust manifold is equipped with two protrusions, and the protrusion is equipped with to be connected with the exhalant canal Opening；The surface of protrusion is arranged in the opening of exhalant canal, conducive to the cooling water outflow in upper and lower water jacket, and then is conducive to hair Wave cooling effect of the upper and lower water jacket to exhaust manifold.

Further, the opening is equipped with inclined surface through raised front end face setting, the opening sidewalls；Opening is through convex Front end face setting is played, and the bottom wall portion that is open tilts down, and then increases water-outlet area, accelerates the water in upper and lower water jacket Flow velocity degree, improves cooling capacity.

Further, the tilt angle of the inclined surface is 30-60 °；Tilt angle is arranged between 30-60 °, further Conducive to the cooling water outflow in upper and lower water jacket, and then improve cooling capacity.

Further, the exhaust manifold is equipped with locating part；The setting of locating part can play limit when assembling cylinder head Position effect, is convenient for assembling process.

Further, the cylinder head ontology is equipped with the gas outlet for being connected to the exhaust manifold, and the protrusion is set respectively In the gas outlet two sides；The two sides of opening are arranged in protrusion, i.e., the cooling water in upper and lower water jacket can be from two effluents of opening Out, more preferable to the cooling capacity of exhaust manifold.

In conclusion the utility model the utility model by exhaust manifold be arranged can Cooling Water circulate it is upper, Lower water jacket, and then exhaust manifold cooling velocity is accelerated, exhaust manifold cooling capacity is improved, exhaust manifold internal fissure is reduced and generates Risk.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.

As shown in Figure 1, a kind of novel cylinder cover water jacket, including cylinder head ontology 1, cylinder head jacket and it is set to the cylinder Exhaust manifold 2 on lid ontology, the cylinder head jacket include upper layer water jacket 3 and lower layer's water jacket 4, are set in the exhaust manifold 2 The lower water jacket 6 for having the upper water sleeve 5 being connected with the upper layer water jacket and being connected with lower layer's water jacket, the exhaust manifold two Side is respectively equipped with the exhalant canal for being connected to the upper water sleeve and lower water jacket, specifically, the cylinder head ontology 1 is equipped with connection institute The gas outlet 21 of exhaust manifold 2 is stated, the exhaust manifold is symmetrically arranged with a cylindrical protrusions 7, institute in the two sides of the gas outlet The opening 8 for stating exhalant canal is arranged on the front end face of the protrusion, cooling water is flowed into from upper and lower layer water jacket respectively, In lower water jacket and finally from 8 outflow of exhalant canal opening being arranged in protrusion, and then realize the cooling effect to exhaust manifold, Reduce the risk that exhaust manifold internal fissure generates.

Preferably, the opening 8 is through raised 7 surfaces setting, and 8 side walls of the opening are equipped with inclined surface, specifically, described The tilt angle of inclined surface is 30-60 °, and preferably 45 °, opening is through raised front end face setting, and the bottom wall portion that is open is downward Inclination, and then water-outlet area is increased, the water velocity in upper and lower water jacket is accelerated, cooling capacity is improved.

Further, 2 upper surface of exhaust manifold is equipped with locating part 22, specifically, the locating part is a truncated cone-shaped The setting of protrusion, the protrusion can play position-limiting action when assembling cylinder head, be convenient for assembling process.

Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts The range of the utility model protection all should belong in every other embodiment.
