Abstract
The utility model discloses a piston cylinder cover. A groove is arranged on the heated surface of the piston cylinder cover. The groove is arranged on the heated surface of the cylinder cover, and the distance between the groove part on the heated surface of the cylinder cover and cooling water is small, so that the heat of the cylinder cover can be fully transmitted to the cooling water through the groove part, thereby generating a better radiating effect. Therefore, the piston cylinder cover disclosed by the utility model can effectively improve the radiating property of the cylinder cover on the basis of keeping the overall thickness of the cylinder cover unchanged. The utility model also discloses a piston which comprises the piston cylinder cover.
Description
Technical field
The utility model relates to technical field of engines, relates to a kind of piston and cylinder cap thereof more specifically.
Background technique
Piston is motor " heart ", bears the mechanical load and the heat load of alternation, is one of worst key components and parts of operating conditions in the motor.The function of piston is to bear gas pressure, and passes to connecting rod through wrist pin and order about the crankshaft rotating acting.
During the indoor oil inflame of piston combustion, the gas in the firing chamber expands, and piston produces relative movement along cylinder sidewall under the pressure effect of high-temperature gas.During oil inflame, produce a large amount of heats in the firing chamber, the cause piston cylinder heats up rapidly.
Usually, the outside of piston cylinder cover is provided with the water-cooled pipeline, through the cooling water of water-cooled pipeline the inside the heat of piston cylinder is taken away.
Yet in the existing technology, in order to satisfy some performance requirements of cylinder cap, it need have certain thickness.Yet the thickness of cylinder cap can not satisfy the requirement of cylinder cap heat dispersion, because the thickness of cylinder cap is bigger, and the heating surface of cylinder cap is a plane structure in the existing technology, thus the heat of cylinder cap difficulty conduct to cooling water and dispel the heat.
Therefore, how guaranteeing to improve the heat dispersion of cylinder cap on the cylinder cap integral thickness basis of invariable, become those skilled in the art's important technological problems to be solved.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of piston cylinder cover, and it can guarantee effectively to improve the heat dispersion of cylinder cap on the cylinder cap integral thickness basis of invariable.
The utility model provides a kind of piston cylinder cover, and the heating surface of said piston cylinder cover is provided with groove.
Preferably, the quantity that is arranged at the said groove on the heating surface of said cylinder cap is at least two.
Preferably, said groove is uniformly distributed in the heating surface of said cylinder cap.
The utility model also provides a kind of piston, comprises like above-mentioned each described piston cylinder cover.
The utility model provides a kind of piston cylinder cover, and the heating surface of said piston cylinder cover is provided with groove.Need to prove; The heating surface of piston cylinder cover means the opposing side of contacted of cylinder cap and cooling water; On the heating surface of cylinder cap groove is set; The groove part and the distance between the cooling water of cylinder cap heating surface are less, so the heat that cylinder cap receives can fully conduct to cooling water through groove part, and then have better radiating effect.Therefore, the piston cylinder cover that the utility model provides, it can guarantee effectively to improve the heat dispersion of cylinder cap on the cylinder cap integral thickness basis of invariable.
The utility model also provides a kind of piston, comprises piston cylinder cover as described above.So be provided with, the piston that the utility model provides on its cylinder cap thickness basis of invariable, has heat dispersion preferably, and the beneficial effect derivation that the derivation of this beneficial effect and above-mentioned piston cylinder cover are brought is similar substantially, so this paper repeats no more.
Description of drawings
Fig. 1 is a piston cylinder cover structural representation in the embodiment of the utility model.
Embodiment
The utility model provides a kind of piston cylinder cover, and it can guarantee effectively to improve the heat dispersion of cylinder cap on the cylinder cap integral thickness basis of invariable.
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, Fig. 1 is a piston cylinder cover structural representation in the embodiment of the utility model.
This embodiment provides starves piston cylinder cover 11, and its heating surface 111 is provided with groove 112.
Need to prove; The heating surface 111 of piston cylinder cover 11 means the opposing side of 12 contacted of cylinder cap and cooling water pipelines; On the heating surface 111 of piston cylinder cover groove 112 is set; So the groove 112 and the distance between the cooling water pipeline 12 of the heating surface 111 of cylinder cap are less, so the heat that cylinder cap receives can fully conduct to cooling water through groove part, and then have better radiating effect.
Therefore, the piston cylinder cover 11 that this embodiment provides, it can guarantee effectively to improve the heat dispersion of cylinder cap on the cylinder cap integral thickness basis of invariable.
For further raising, the heat dispersion of cylinder cap, the piston cylinder cover 11 that this embodiment provided; The quantity of the groove 112 that is provided with on its heating surface 111 is at least two; Such as, can be provided with ten, five, 15 etc., the concrete quantity of setting can be set as the case may be.
So be provided with, on the heating surface 111 of cylinder cap more groove 112 be set, the heat on its heating surface 111 more is prone to conduct to cooling water, thereby has further improved the heat dispersion of cylinder cap.
Further, above-mentioned a plurality of groove 112 can be uniformly distributed on the heating surface 111 of cylinder cap.So be provided with, the heat radiation of cylinder cap is more even, and radiating effect is better.
This embodiment also provides a kind of piston, comprises piston cylinder cover as described above.
So be provided with; The piston that this embodiment provided on its cylinder cap thickness basis of invariable, has heat dispersion preferably; The beneficial effect derivation that piston cylinder cover brought in the derivation of this beneficial effect and the above-mentioned embodiment is similar substantially, so this paper repeats no more.
More than a kind of piston and cylinder cap thereof that the utility model provided have been carried out detailed introduction; Used concrete example among this paper the principle and the mode of execution of the utility model are set forth, above embodiment's explanation just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
