Abstract
The utility model discloses a cooling structure for the cylinder cover of the engine and a diesel engine of the cooling structure. The cylinder cover is sleeved in the cylinder hole in the cylinder, an aquifuge lug fitted with the interface of the cylinder cover is arranged in the cylinder, and a concave water through groove is arranged on the aquifuge lug. The utility model has the advantages such as a simple structure and an evenly and fully cooling of the cylinder cover, which can be applied to the cylinders of the diesel engines of different types.
Description
Technical field
The utility model relates to a kind of cooling structure, relates in particular to a kind of cylinder sleeve cooling structure and motor of cylinder of diesel engine.
Background technique
The cooling structure of ordinary diesel oil machine wet liner adopts cooling water to be filled in around the cylinder liner more.Flow to cylinder cap from cylinder liner top after setting up hydraulic pressure.Such cooling structure makes that flow of cooling water is permanent flow velocity, and the temperature of cylinder liner everywhere inequality to have height to have low, need the degree of heat radiation different everywhere, thereby the cylinder liner cooling is insufficient, inhomogeneous, do not reach desirable cooling effect, when engine operation, cylinder liner localized hyperthermia, cause a series of adverse effect easily, cause scuffing of cylinder bore, wearing and tearing more greatly as cylinder liner deformation.The direct reliability that influences the performance of motor or reduced motor.
Summary of the invention
At the deficiencies in the prior art, when the utility model provided a kind of engine operation, cylinder liner can obtain evenly fully cooling, the cylinder sleeve cooling structure of the uniform cylinder of diesel engine of heat radiation of cylinder liner and the diesel engine of using this structure on the whole.
The cylinder sleeve cooling structure of the utility model engine cylinder, the cylinder sleeve cooling structure of described cylinder block comprises two or more jacket structure for water bodies, described jacket structure for water body is installed the gentle outer wall of cylinder jachet of hole wall by the cylinder liner of cylinder of diesel engine and is formed, described jacket structure for water body comprises the intake-outlet that is opened in respectively on the cylinder of diesel engine, and described intake-outlet is separately positioned on the relative side end face of described cylinder block.When being contained in cylinder liner in the cylinder liner mounting hole in the cylinder block, cylinder liner is installed between hole wall and the cylinder liner outer wall and is formed cooling jacket, is provided with the water proof circle flange with cylinder liner outer wall Spielpassung in the cylinder liner installation hole wall.
In the utility model cylinder sleeve cooling structure, the tank of crossing of depression is set on described water proof circle flange, crosses the tank shape and can be any suitable shape, cross tank quantity and can design 2～12, generally design 4～8 and get final product, cross tank and preferably evenly be provided with.Take circumferential clearance to cooperate between water proof circle flange and the cylinder liner, the gap is generally 1～3mm.Cooling water intake is lower edge on cylinder liner installation hole wall, and cooling water outlet is at the upper limb of cylinder liner installation hole wall, and is relative with the cooling water intake position.Cooling water intake is arranged on the following and cylinder liner localized hyperthermia relevant position of water proof circle flange, and cooling water outlet is arranged on more than the water proof circle flange.Water proof circle flange is arranged on cylinder liner localized hyperthermia relevant position, and a circle or a multi-turn can be set, and operated by rotary motion one circle gets final product.
The utility model diesel engine is used the cylinder sleeve cooling structure of above-mentioned cylinder.
Of the present utility model by with the water proof circle flange of cylinder liner outer wall Spielpassung, cooling water be filled in cylinder liner around, lead to cylinder sleeve top by crossing tank and gap then, cooling water leaves cooling jacket by the water outlet on cylinder sleeve top.Cooling-water flow is promptly taken away heat because artificial design path improves the cooling water flow velocity in the place of cylinder liner high temperature like this, and the assurance that makes cylinder liner evenly be cooled off on the whole, fully cool off reaches desirable cooling effect.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, simple in structure;
2, the cylinder liner cooling evenly, fully;
3, the distortion of cylinder liner is little.
Description of drawings
Fig. 1 is the cylinder sleeve cooling structure schematic representation of the utility model cylinder of diesel engine;
Fig. 2 is the cylinder sleeve cooling structure assembling condition sectional drawing of the utility model cylinder of diesel engine.
Wherein: 1-water proof circle flange; 2-crosses tank; The 3-cooling water intake; The 4-cylinder block; The 5-cooling jacket; 6-cylinder liner (assembling condition); The 7-cooling water outlet.
Embodiment
As shown in the figure, the cylinder sleeve cooling structure of the utility model cylinder of diesel engine, cylinder liner is packed in the cylinder block 4, after cylinder liner 6 assemblings, 1～3 millimeter circumferential clearance passage is arranged, improve the cooling water flow velocity by this passage with water proof circle flange 1, cooling water enters cooling jacket 5 from the cooling water intake 3 of cylinder block 4, after being filled in around the cylinder liner full and uniformly, improving flow velocitys by circumferential clearance passage and mistake tank 2 again and leave cooling jacket 5, leave cylinder block 4 by cooling water outlet 7 again.
Cooling water owing to designed water proof circle flange artificially and crossed tank, improves the cooling water flow velocity in the cylinder sleeve high-temperature zone in the process to the cylinder sleeve cooling, promptly take away the heat of high-temperature zone, and localized hyperthermia's problem of cylinder liner is resolved.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
