Description
Technical field
The utility model is related to a kind of engine cooling water jacket structure.
Background technology
In order to reduce engine chamber wall surface temperature, improve HP, hp/litre and improve the discharge performance of engine,
Diesel engine at this stage all employs water-cooling structure substantially.Water-cooled engine is designed with cooling water in cylinder cap and cylinder body
Set, drives coolant to be circulated in engine and cooling system to cool down engine, while in cooling system by water pump
In be provided with thermostat, and take into account cooling engine motor oil.
And available engine is generally multi-cylinder structure, but due to distance difference of the cylinder body in tandem away from water pump, cause
The cooling water flow that front and rear each cylinder flows through differs greatly.Conventional cylinder block cooling water set, due at the first cylinder body left side
Cylinder body and cylinder cap wall are very thin, the related structure of frontal attachments are distributed with again, it is impossible to design led to by cylinder body water jacket here
The upper water hole of cylinder cap, thus it is considerably less by the coolant on the left of the first cylinder, flow dead is easily formed in water jacket, causes cold
Bad, especially proximate to the high-temperature area of upper end, so as to cause housing structure temperature too high, housing structure produces thermal deformation and entered
And larger thermal strain is produced, reduce intensity and the life-span of cylinder block.
Utility model content
The technical problems to be solved in the utility model is：Deficiency in the prior art is overcome to eliminate cylinder body there is provided one kind
Flow dead and the engine cooling water jacket structure of thermal stress is prevented in the water jacket of side.
The utility model solves the technical scheme that its technical problem used：A kind of engine cooling water jacket structure, bag
The cooling jacket being provided with the engine body that cylinder body and cylinder cap are constituted, described engine body for coolant flow is included,
Engine body left side is provided with water pump, and described cooling jacket includes the cylinder body water jacket being located in cylinder wall and is located at cylinder cap
The water hole of cylinder cover water jacket is communicated with cylinder cover water jacket in wall, cylinder body water jacket, cylinder body water jacket water side connects with water pump, is located at
Pod apertures are offered in the cylinder wall of engine body left side, described pod apertures one end is connected with cylinder body water jacket, pod apertures
The other end is connected with the water cavity of water pump.
Preferably, described pod apertures are cavity of the section in kidney-shaped shape.
The beneficial effects of the utility model are：The utility model passes through first cylinder wall in engine body left side
Interior setting section is in the pod apertures of kidney-shaped shape, and the sub-fraction coolant for flowing through cylinder body water jacket flows directly into water from the pod apertures
Pump, you can reach elimination flow dead and the purpose of thermal stress will not be produced, manufacture and experimental cost are relatively low.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of A-A in Fig. 1.
The pod apertures of 1. engine body, 2. cooling jacket, 3. water pump 4. in figure
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of engine cooling water jacket structure as shown in Figure 1 and Figure 2, including engine body 1, described engine machine
Body 1 is made up of four cylinder bodies and four corresponding cylinder caps, and the cooling jacket 2 for coolant flow is provided with engine body 1,
The left side of engine body 1 is provided with water pump 3, and described cooling jacket 2 includes the cylinder body water jacket being located in cylinder wall and is located at
The water hole of cylinder cover water jacket is communicated with cylinder cover water jacket in cylinder cover wall, cylinder body water jacket, cylinder body water jacket water side connects with water pump 3
It is logical, pod apertures 4 are offered in first cylinder wall of the left side of engine body 1, described pod apertures 4 are section in waist
The cavity of shape, one end of pod apertures 4 is connected with the cavity of cylinder body water jacket, and the other end of pod apertures 4 is connected with the water cavity of water pump 3.
The engine cooling water jacket structure of said structure, coolant enter from the bottom of engine body 1 by cylinder body water jacket and
Cylinder cover water jacket connects the cooling jacket 2 to be formed and flowed, and water pump 3 is flowed into from the cylinder body water jacket positioned at the top of engine body 1, with this
Simultaneously as being provided with first cylinder wall for easily producing flow dead after pod apertures 4 of the section in kidney-shaped shape, it can make
The sub-fraction coolant that cylinder body water jacket must be flowed through flows directly into water pump 3 from the pod apertures 4, to eliminate in the prior art first
The flow dead that individual cylinder body side is present, guides coolant into low-pressure area, so as to increase the coolant flow scope in the region, carries
The high region radiating effect, and said structure will not produce thermal stress after cylinder body heating, and can be big by changing pod apertures 4
Small and between the blade of water pump 3 gap reaches the purpose of regulation cooling effect.
The cross sectional shape of the pod apertures 4 is not limited to above-mentioned kidney-shaped shape, the Kong Junke of other any shapes.
And if the water pump 3 used in engine is not installed on the left side of engine body 1, then can be by designing water hole
And water pipe, coolant is led into the entrance water pipe of water pump 3 from pod apertures 4, first cylinder body side of elimination can also be equally realized
There is the purpose of flow dead in cylinder body water jacket.
The utility model need to only increase by one of Drilling operation technique, by engine body 1 left side, first cylinder body
Processing section is in the pod apertures 4 of kidney-shaped in wall, you can the sub-fraction coolant for flowing through cylinder body water jacket is direct from the pod apertures 4
Water pump 3 is flowed into, to reach elimination flow dead and will not produce the purpose of thermal stress, manufacture and experimental cost are relatively low.
Above-mentioned embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence should all cover in protection model of the present utility model
In enclosing.
