As the cooling path of water is prolonged, and a square hole shape cooling water cavity or a convex shape cooling shape is adopted, the utility model has the advantages that the engine can be effectively cooled through cooling water, thereby the temperature of the engine during the working can be reduced, and the reliability of the engine can be improved; and simultaneously, the manufacture manner of the cylinder body is changed, and the manufacture coast of the engine is reduced.
Description
Technical field
The utility model relates to a kind of cylinder block of motor, and the motor that comprises this cylinder block.
Background technique
Motor is in the condition of high temperature in working order down always, if thereby too high rotten each component that cause of machine oil that will cause of temperature lubricate decline so that accelerate component wear, produce " scuffing of cylinder bore " phenomenon when serious, " puncture " phenomenon appears in piston head, and piston ring " adhesion " phenomenon occurs at piston ring groove internal cause carbon deposit.Therefore, the reliability of motor is low.How cooled engine is insoluble always technical problem.The common type of cooling is that the cylinder block feeding cooling water circulation of motor is cooled off, therefore the cooling effect of the flow path countercylinder body in cylinder block of water is extremely important, but the flow path of existing cylinder block design is short, therefore the heat exchanger time of water and cylinder block is short, thereby causes the cooling effect of countercylinder body undesirable; In addition, existing cylinder body generally adopts cast form, so manufacture cost is higher, and the efficient of processing is also very low.
The model utility content
The purpose of this utility model is to provide a kind of engine cylinder body of good cooling results.
The motor that provides a kind of reliability high is provided another purpose of the present utility model.
The purpose of this utility model is achieved through the following technical solutions: a kind of motor, comprise cylinder block, the water intake and the water outlet that are provided with cooling water chamber in the described cylinder block and communicate with described cooling water chamber, it is characterized in that: described water intake is arranged on two relative sidewalls of described cylinder block with described water outlet, and described water intake is arranged on the bottom of described cylinder block, and described water outlet is arranged on described cylinder deck.
Be to increase film-cooled heat, described cooling water chamber be shaped as " mouth " shape.
For fully rationally utilizing existing structure, described cooling water chamber be shaped as " protruding " shape, this moment, described cooling water chamber can be designed to comprise major cycle chamber and short circle chamber, the cross-sectional flow area in described short circle chamber is less than the cross-sectional flow area in described major cycle chamber.
For ease of making, a side and place, the corresponding described major cycle of described cylinder block chamber that described cylinder block is not provided with water intake and water outlet are provided with major cycle chamber lid, and a side and place, the corresponding described short circle of described cylinder block chamber that described cylinder block is not provided with water intake and water outlet are provided with short circle chamber lid.
Another goal of the invention of the present utility model realizes by above-mentioned cylinder block is installed on motor.
The beneficial effects of the utility model are:
(1) because described water intake is arranged on two relative sidewalls of described cylinder block with described water outlet, so the cooling path of water is long, the good cooling results of water countercylinder body, institute is so that the temperature maintenance of motor when working is lower;
(2) because described water intake is arranged on the bottom of described cylinder block, described water outlet is arranged on described cylinder deck, therefore the cooling path of water is longer, and water enters, flows out from higher temperatures, so the cooling effect of countercylinder body is better from the lower temperature of cylinder block;
(3) since described cooling water chamber be shaped as " mouth " shape, so water is big to the film-cooled heat of motor, thereby can well reduce the temperature of motor;
(4) because described cooling water chamber comprises major cycle chamber and short circle chamber, the cross-sectional flow area in described short circle chamber is less than the cross-sectional flow area in described major cycle chamber, be cooling water chamber be shaped as " protruding " shape, therefore can available engine not done big improvement, thereby reduced the cost of manufacturing;
(5) because place, the corresponding described major cycle of described cylinder block chamber is provided with major cycle chamber lid, place, the corresponding described short circle of described cylinder block chamber is provided with short circle chamber lid, guaranteeing that the cylinder body performance can change manufacture again in constant, promptly can change die casting into by original casting mode, therefore reduce manufacture cost, improved work efficiency;
Structural design in sum, the good cooling results of water countercylinder body, the reliability height of motor.
