Abstract
The utility model disclose a kind of return pipe device in the engine cylinder, including a water outlet passage which can be connected to the pump; the water outlet passage is set on the side of the cylinder body; on the cylinder body is still set the backwater passage which can be connected to the backwater nozzle of the engine cylinder head; the backwater passage is connected to the water outlet passage. The model solves the problem that the cooling water is easy to leak, as a result of the separate design and manufacturing of the water outlet pipe and the cylinder body, which increase the assembly difficulty and the maintenance cost. This kind of integration of the engine cylinder body can be analyzed wholly from the fluid dynamics; the model reduces the backwater resistance, and enhances the cooling effect. The inner and outer surfaces of the water outlet passage are the rugged and curved surface of arc shape, which can fully absorb the noise radiation in the upper space of the exhaust side of the cylinder body and the outer cylinder surface and effectively reduce the noise of the engine.
Description
Technical field
The utility model relates to a kind of engine cylinder return pipe device.
Background technique
Known diesel engine all is with cooling water outlet pipe and cylinder block split design and makes that outlet pipe is fixed on the cylinder head by pad and clamping bolt, tends to like this because the loosening or damage of bolt and pad causes cooling water to leak; Because outlet pipe designs the component that increased many special uses separately, has increased assembling difficulty and maintenance cost; The outlet pipe and the cylinder block of split design are difficult in the resistance of considering backwater on the whole, tend to cause the backwater resistance big like this, influence the performance of motor.
The model utility content
Technical problem to be solved in the utility model is: a kind of engine cylinder return pipe device is provided, to solve in the known technology, because outlet pipe and cylinder block body split design and manufacturing cause cooling water to leak easily, increase the problem of assembling difficulty and maintenance cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: engine cylinder return pipe device, comprise an exhalant canal that can be communicated with water pump, described exhalant canal is arranged at the sidepiece of cylinder block body, described cylinder block body also is provided with the backwater channel that can be communicated with the engine cylinder cap backwater mouth, and described backwater channel is communicated with described exhalant canal.
Because the sidepiece of described cylinder block body is provided with an exhalant canal that can be communicated with water pump, also be provided with the backwater channel that can be communicated with the backwater mouth of engine cylinder cap, described backwater channel is communicated with described exhalant canal, can make the gentle cylinder body body of outlet pipe carry out integrated design like this, when having avoided outlet pipe to be connected, because of the loosening of connecting bolt and pad or damage the problem that causes cooling water to leak, simultaneously with cylinder head, reduce assembling difficulty, reduced maintenance cost.What is more important, this integrated design can be carried out flow dynamics analysis on the whole, reduces the backwater resistance, strengthens cooling effect.
As a kind of improvement, the inner surface of described exhalant canal and outer surface all are rough arc-shaped curved surfaces.The uneven curved surface of these arcs can fully absorb the noise radiation of the gentle outer surface of cylinder block of cylinder block body exhaust side upper space, effectively reduces the noise of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a transverse sectional view.
Embodiment
Engine cylinder return pipe device, as shown in drawings, engine cylinder return pipe device, comprise an exhalant canal 12 that can be communicated with water pump, described exhalant canal 12 is arranged at the sidepiece of cylinder block body 1, described cylinder block body 1 also is provided with the backwater channel 11 that can be communicated with the engine cylinder cap backwater mouth, and described backwater channel 11 is communicated with described exhalant canal 12.
Cylinder block body 1 adopts the cast-in-block form, and during casting, the exhalant canal inner chamber adopts a complete fuse, and clear husky hole is reserved in the outside.When designing water channel 12, fully take into account the noise radiation of the gentle outer surface of cylinder block of cylinder body exhaust side upper space, so the rough curved surface of arc is equally adopted on the inside and outside surface of exhalant canal 12 with the other parts of cylinder body 1.
