Abstract
The utility model discloses a multi-cylinder engine cylinder body water sleeve structure, which mainly comprises a cylinder body water sleeve, a cylinder body water sleeve air inlet side and a cylinder body water sleeve air exhaust side. A plurality of cylinder nose bridge areas are arranged on the cylinder body water sleeve; and each two oppositely arranged cylinder nose bridge areas are communicated through inclined water holes. By arranging the inclined water holes for communicating with different shapes among the cylinder nose bridge areas, cooling liquids on the air inlet side and the air exhaust side are mutually communicated in order to improve heat exchange in a localized area with small heat exchange coefficient, thereby adding cooling water passages among cylinders and improving cooling effect under the condition of not changing the outer contour size of a cylinder body.
Description
Technical field
The utility model relates to a kind of multicylinder engine cylinder body water jacket structure, belongs to the vehicular engine technical field.
Background technique
Present automobile-used multicylinder engine cylinder body, arranged around has cooling jacket in the cylinder hole.Around cooling liquid can only arrive each cylinder hole along water jacket successively from the water pump side, and then enter into opposite side.And in cylinder body bridge of the nose district, i.e. part between two cylinders.
For the compactedness that guarantees housing structure and the mechanical strength in cylinder hole, the centre does not have cooling water channel to be communicated with.Like this, in the nearer side of dried up pump, good cooling results, in the side away from water pump, cooling effect is poor.
The model utility content
The utility model has designed a kind of multicylinder engine cylinder body water jacket structure, and it has solved the unbalanced problem of the heat exchange that occurs in the cylinder body water jacket.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of multicylinder engine cylinder body water jacket structure, mainly comprise cylinder body water jacket, cylinder body water jacket air inlet side and cylinder body water jacket exhaust side, on described cylinder body water jacket, be provided with a plurality of cylinder body bridge of the noses district, be communicated with by oblique water hole between described two cylinder body bridge of the nose districts that establish relatively.
Described cylinder body water jacket air inlet side and cylinder body water jacket exhaust side are communicated with by described oblique water hole.
Described oblique water hole be " X ", " Y ", " V ", " " or "/" type.
This multicylinder engine cylinder body water jacket structure is compared with existing jacket structure for water, have following beneficial effect: the utility model is owing to be provided with difform oblique water hole connection between each cylinder body bridge of the nose district, the cooling liquid of inlet and outlet both sides is run through mutually, to improve the heat exchange of the little regional area of the coefficient of heat transfer.Making has like this increased cooling water channel between each cylinder under the situation that does not change cylinder body boundary dimension, improved cooling effect.

Embodiment
Below in conjunction with Fig. 1 to Fig. 8, the utility model is described further:
As depicted in figs. 1 and 2, a kind of multicylinder engine cylinder body water jacket structure, mainly comprise cylinder body water jacket 1, cylinder body water jacket air inlet side 4 and cylinder body water jacket exhaust side 5, on described cylinder body water jacket 1, be provided with a plurality of cylinder body bridge of the noses district 2, be communicated with by oblique water hole 3 between described two cylinder body bridge of the nose districts 2 that establish relatively.
As shown in Figure 3, further, described cylinder body water jacket air inlet side 4 and cylinder body water jacket exhaust side 5 are communicated with by described oblique water hole 3.This oblique water hole 3 is " V " font.Adopt such structure, all there is certain flow velocity in cooling liquid oblique water hole 3 between each cylinder, has improved the coefficient of heat transfer of inlet and outlet side 4,5, makes the cooling of cylinder hole, both sides evenly.Making has like this increased cooling water channel between each cylinder under the situation that does not change cylinder body boundary dimension, improved cooling effect.
As shown in Figure 4, this oblique water hole 3 is " X " font.
As shown in Figure 5, this oblique water hole 3 is " Y " font.
As shown in Figure 6, this oblique water hole 3 also is " Y " font.Just there are two place's tie points in this oblique water hole 3 with cylinder body water jacket air inlet side 4.
As shown in Figure 7, this oblique water hole 3 be " " font.
As shown in Figure 8, this oblique water hole 3 is "/" font.
Water velocity and the coefficient of heat transfer are calculated or by testing the optimum scheme of selecting by CFD in the oblique water hole 3 of these several forms when selecting for use.Usually, cylinder body bridge of the nose district 2 cooling water flow velocity integral body are less, and the coefficient of heat transfer is little, and temperature is higher, and especially exhaust side 5.By adopting this oblique water hole 3, can increase the cooling water flow velocity in cylinder body bridge of the nose district 2, make each cylinder cooling evenly.
