Abstract
The utility model discloses cooling structure between a kind of engine cylinder, comprise the cooling water channel (4) in engine cylinder-body (1) and engine cylinder-body (1), the two ends of cooling water channel (4) are communicated with the cooling jacket (2) on engine cylinder-body (1); The cross section of cooling water channel (4) is rectangle, and the axes normal of the center line of the length direction of cooling water channel (4) and cooling jacket (2), cooling water channel (4) and engine cylinder-body (1) are integrated an entirety of moulding by casting.After adopting above structure, eliminate mach operation, improve the reliability of engine cylinder-body; In addition, farthest ensure that the cooling effect of engine cylinder-body heat load, improve the thermal fatigue risk of engine cylinder-body.
Description
Technical field
The utility model relates to technical field of engines, is specifically cooling structure between a kind of engine cylinder.
Background technique
At present, the world today is high-performance, low oil consumption, lightweight and compactness to the new demand that automotive engine applications proposes, and these requirements are also more and more higher to the requirement of engine-cooling system, this is because these requirements certainly will bring the heat load of motor to increase, cause the temperature between motor two adjacent cylinder (being commonly referred to temperature between cylinder) very high, if there is no rational cooling system to ensure the reduction of making single temperature, so will cause that engine cylinder bore deformation, oil consumption are high, piston air leakage is high, even occur the series of problems such as scuffing of cylinder bore.In prior art, between engine cylinder, cooling structure mainly contains between cylinder and punches and grooving two kinds of predominate architecture between cylinder.
For perforation structure between cylinder, disclosed in State Intellectual Property Office website, publication number is " cooling aouatic structure between a kind of cylinders of cylinder block " of CN201739016U, it comprises cylinder body, cylinder body is provided with air inlet side water pump and exhaust side water jacket, a V-shaped cooling water channel is provided with in ridge area between each cylinder of cylinder body, cooling water channel one end is connected with air inlet side water jacket, and the other end is connected with exhaust side water jacket.But, air inlet side water jacket and exhaust side water jacket are arranged in parallel, cooling water channel is located between two parallel water jackets, due to the restriction of structure, certainly will be beat inclined hole from one of them water jacket, from another one water jacket, beat inclined hole, two inclined holes are communicated with in cylinder interior, so just form a V-arrangement cooling water channel.But, this cooling structure Problems existing is: on the one hand, in the actual production process of motor, because inclined hole is general darker, if the diameter in hole is too little will cause the technological problemses such as breaking, therefore, the diameter of inclined hole is general all at more than ￠ 3mm, the structure of thus beating inclined hole between cylinder is only suitable for the larger situation of width between cylinder, carries out punch operation to ensure sufficient space.And for the less engine cylinder-body of width between cylinder, the scheme of processing inclined will cause cylinder bore wall thickness not enough, cause the problems such as engine damage.Two aspects, the setting of this inclined hole is restricted because of the position of cooling jacket, therefore, it can not arbitrarily be shifted one's position, and the maximum region of heat load is the first ring position being positioned at top dead center at piston between engine cylinder, so it also can the maximum region of heat load between cooled engine cylinder, the best cooling effect between cylinder cannot be realized.
For the structure of grooving between cylinder, cylinder body normally between adjacent two cylinder holes cuts out the straight trough of an opening, the two ends of straight trough are communicated with two cooling jackets, shrouding is connected again on the end face of straight trough opening and engine cylinder-body, shrouding and straight trough bottom land is made to reserve certain height, like this, between the cylinder body at shrouding and straight trough place, form a cooling water channel perpendicular to cooling jacket axis, and the position of cooling water channel also can be arranged on the maximum region of heat load between engine cylinder.But this cooling structure Problems existing is: cylinder body is equivalent to be constituted by two-part, assemble again after processing separately, therefore, on the one hand manufacturing procedure is increased, correspondingly just add cost of production; Two aspects add assembly process, reduce manufacturing efficiency; Three aspects, this split type structure certainly will need to carry out sealing at junction plane and arrange, otherwise can produce the phenomenon of leaking, therefore, junction plane between shrouding and cylinder body to arrange Sealing, then add the complexity of structure, too increase cost of production equally.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of cooling water channel and engine cylinder-body integrally casting is shaping forms, thus realizes best cooling effect, and economizes operation, reduces costs, strengthens cooling structure between the engine cylinder of sealing.
For solving the problems of the technologies described above, cooling structure between the engine cylinder that the utility model provides, comprises the cooling water channel in engine cylinder-body and engine cylinder-body, and the two ends of cooling water channel are communicated with the cooling jacket on engine cylinder-body; The cross section of described cooling water channel is rectangle, and the center line of the length direction of cooling water channel and the axes normal of cooling jacket, cooling water channel and engine cylinder-body are integrated an entirety of moulding by casting.
The cross-sectional width of described cooling water channel is 1.5mm ± 0.1mm, and cross-sectional height is 4.5mm ± 0.1mm.
Described cooling water channel is positioned at the top dead center place of engine cylinder-body near cylinder holes end face.
After adopting above structure, the utility model compared with prior art, has the following advantages:
1) due to the entirety that cooling water channel between engine cylinder and engine cylinder-body one are poured into a mould, because omitted herein the operation of punching, thus saving cost, improve the manufacture efficiency of product; Meanwhile, also ensure that the sealability of cooling water channel;
2) simultaneously, cooling water channel, in being horizontally disposed with, is placed on the position that between engine cylinder, heat load is maximum as required, thus realizes best cooling effect, thus substantially increases engine performance and functional reliability.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
From the structural representation of cooling structure between the utility model engine cylinder shown in Fig. 1 ~ Fig. 3, it comprises the cooling water channel 4 in engine cylinder-body 1 and engine cylinder-body 1, and the two ends of cooling water channel 4 are communicated with the cooling jacket 2 on engine cylinder-body 1.The cross section of described cooling water channel 4 is rectangle, and the axes normal of the center line of the length direction of cooling water channel 4 and cooling jacket 2, cooling water channel 4 and engine cylinder-body 1 are integrated an entirety of moulding by casting.
The cross-sectional width of described cooling water channel 4 is 1.5mm ± 0.1mm, and cross-sectional height is 4.5mm ± 0.1mm.
