Abstract
The utility model belongs to the technical field of the engine, a cooling jacket has engine cylinder block of water conservancy diversion structure of dividing is related to. Through increase the water conservancy diversion structure on engine cylinder block cooling jacket, the realization is to the inside rivers channeling conduct of cylinder body water jacket, the flow velocity distribution in the water jacket has been improved, local flow area has been changed simultaneously, realized that the inclined water hole both ends form higher pressure differential between the jar, thereby make the inside velocity of flow increase of inclined water hole between the jar, take away heat between more jars in unit interval, heating load between the jar has been reduced, thereby the indirect cooling that has improved the interior moving part of jars such as piston ring alive, the interior moving part's of jar life has been prolonged.
Description
Technical field
This utility model belongs to technical field of engines, is related to the electromotor that a kind of cooling jacket has point water flow-guiding structure
Cylinder body, it is adaptable to electromotor of the type of cooling for water-cooled.
Background technology
In recent years, with the raising of gasoline engine reinforcing degree, the thermic load of engine component also increases therewith.Generally,
Between high strengthening cylinder of petrol engine cylinder using between processing cylinder tiltedly the type of cooling in water hole reducing thermic load between cylinder.But, it is most of
Electromotor coolant before and after it increased between cylinder behind oblique water hole due to oblique water hole is formed without imitating pressure differential, causes oblique water hole local
Flow velocity is relatively low, and between cylinder, temperature is higher, and cooling effect is poor.Therefore, how the higher problem of effectively solving cylinder body thermic load is also urgently
Solve.
The content of the invention
The purpose of this utility model is that for above-mentioned the deficiencies in the prior art, there is provided a kind of cooling jacket has a point water
The engine cylinder-body of flow-guiding structure.
The purpose of this utility model is achieved through the following technical solutions, as follows in conjunction with illustrating：
A kind of cooling jacket has the engine cylinder-body of point water flow-guiding structure, cold in engine cylinder-body 2 including being arranged on
But oblique water hole 3 between water jacket 5 and cylinder；The front and back ends of the cooling jacket 5 are respectively provided with front flow-guiding structure 6 and rear flow-guiding structure
1。
Described front flow-guiding structure 6 is located on the right side of cylinder center line 4, i.e. water (flow) direction downstream, in its centre distance cylinder body
Heart line 4 is 19.9mm, and its top surface is 17.2mm away from water jacket floor height, and width is 24.8mm.Flow-guiding structure 1 after described water jacket
On the right side of cylinder center line 4, i.e. water (flow) direction upstream, its centre distance cylinder center line 4 are 19.3mm, and its top surface is away from water
Set floor height is 24.8mm, and width is 27.9mm.
Compared with prior art, the beneficial effects of the utility model are：
By increasing front guiding device and rear guiding device in cooling jacket front and back end, realize to cylinder body water jacket water flow inside
Guide, improve the velocity flow profile in water jacket, while changing local circulation area, realize the oblique water hole two ends between cylinder
Higher pressure differential is formed, so that flow velocity increase inside oblique water hole between cylinder, takes away heat between more cylinders in the unit interval,
Thermic load between cylinder is reduced, so as to improve indirectly the cooling of moving component in the cylinders such as piston ring, moving component in cylinder is extended
Service life.

Specific embodiment
A kind of cooling jacket has the engine cylinder-body of point water flow-guiding structure, cold in engine cylinder-body 2 including being arranged on
But oblique water hole 3 between water jacket 5 and cylinder；The front and back ends of the cooling jacket 5 are respectively provided with front flow-guiding structure 6 and rear flow-guiding structure
1；Described front flow-guiding structure 6 is located on the right side of cylinder center line 4, i.e. water (flow) direction downstream, and its centre distance cylinder center line 4 is
19.9mm, its top surface are 17.2mm away from water jacket floor height, and width is 24.8mm；After described water jacket, flow-guiding structure 1 is located at cylinder
On the right side of body centrage 4, i.e. water (flow) direction upstream, its centre distance cylinder center line 4 is 19.3mm, and its top surface is high away from water jacket bottom surface
Spend for 24.8mm, width is 27.9mm.
The flow-guiding structure 6 before 5 front end of cooling jacket of engine cylinder-body 2 increases, increases with rear end is covered in cylinder block cooling water
Flow-guiding structure 1, can guide to 5 interior flow field of cooling jacket afterwards, and between cylinder form pressure differential before and after oblique water hole 3, change
It has been apt to coolant flow in cylinder, has enhanced.
This utility model is guided to cylinder body water jacket water flow inside in the internal increase flow-guiding structure of cylinder block cooling water set,
Change the distribution of water jacket internal pressure simultaneously, improve oblique water hole cooling liquid speed between cylinder.Local in engine cylinder-body inside water jacket
Circulation area and flow field are varied so that between cylinder that oblique water hole two ends form higher pressure differential, so as to increase oblique water between cylinder
Flow velocity inside hole, and cause cylinder sleeve upper coolant flow velocity increase, strengthen between cylinder and cylinder sleeve top cooling effect, reduce
The thermic load of corresponding site, so as to improve indirectly the cooling of movement parts in the cylinders such as piston ring, extends moving component in cylinder
Service life.
