Description
Technical field
The invention belongs to car engine cooling systems, and in particular to a kind of engine cooling water jacket.
Background technology
Engine cooling water jacket is made of block jacket and cylinder head jacket, at present common cooling jacket be disposed with
Lower two kinds：
One, coolant liquid enters block jacket after water pump pressurizes, and flows through cylinder pad water hole and enters cylinder head jacket, then
Engine body is flowed out by cylinder head jacket, this jacket structure for water is simple and easily controllable, but in order to ensure each cylinder temperature of engine
It spends close, water hole on cylinder pad is caused to change, the flow velocity lack of homogeneity in water jacket with increasing at a distance from pump house, it is cold
But efficiency is relatively low；And because arrangement reason keeps the cooling of the high temperature places such as cylinder head exhaust valve ridge area insufficient, and then limit hair
The promotion of motivation bulk temperature.
Two, coolant liquid separately flows into one end of block jacket and cylinder head jacket after water pump pressurizes, then from cylinder
Body water jacket and the other end of cylinder head jacket flow out engine body, and are controlled respectively by individual thermosistor, Ci Zhongbu
The non-uniform problem of cooling liquid speed in water jacket can be obviously improved by setting, and improve cooling efficiency.But the problem is that：It is cooling
During liquid lateral flow, temperature, which gradually rises, can cause the cooling effect far from water inlet region poor, and high-temperature area
There is also the insufficient problem of cooling, the cooling jacket of such structure restricts the further promotion of engine temperature；And structure
More complex, manufacturing cost is higher.
Therefore, it is necessary to develop a kind of new engine cooling water jacket.
Invention content
The object of the present invention is to provide a kind of engine cooling water jackets, it has, and simple in structure, flow velocity is uniform, flow resistance is small,
Keep each position cooling of engine uniform.
Engine cooling water jacket of the present invention, including block jacket and cylinder head jacket, cylinder head jacket include
It is separately positioned on the first auxiliary waterexit mouth, the second auxiliary waterexit mouth and three groups of coolant inlets of cylinder head exhaust side, and setting exists
Three groups of cooling liquid outlets of cylinder head air inlet side, three groups of coolant inlets are corresponded with three groups of cooling liquid outlets；Every group of cooling
Liquid entrance and corresponding one group of cooling liquid outlet correspond to a cylinder；Each cylinder correspond to a cylinder head exhaust duct region and
One cylinder head air intake duct region, the nasal bridge region in the middle part of each cylinder head exhaust duct region are equipped with cooling water channel, each
One end of cooling water channel is communicated with same group of coolant inlet, and the other end of each cooling water channel is connected by an exhaust passage
Logical, which communicates with the peak of cylinder head jacket, and one end of exhaust passage is connected to the first auxiliary waterexit mouth, and exhaust is logical
The other end in road and the connection of the second auxiliary waterexit mouth；
Partition board there are two being set in block jacket, is divided into exhaust side cylinder block by two partition boards by block jacket
Water jacket and air inlet side block jacket two parts are equipped with water main inlet port, in air inlet side gas in the front end of exhaust side block jacket
The bottom of cylinder body water jacket front end is equipped with secondary water inlet, and main water outlet is equipped in the rear end of air inlet side block jacket；
When coolant temperature is relatively low, engine-cooling system carries out partial circulating, coolant liquid from the master of block jacket into
The mouth of a river enters exhaust side block jacket, and coolant liquid from the coolant inlet of cylinder head jacket enters cylinder head water after being sufficiently mixed
Set, in cylinder head exhaust duct region, the heat of fuel oil burning release is taken away in flowing, and coolant liquid is then introduced nose through cooling water channel
Beam region enters exhaust passage, most the first auxiliary waterexit mouth and second through cylinder head jacket afterwards after being cooled down to nasal bridge region
Auxiliary waterexit mouth flows out engine；
When coolant temperature is higher, engine-cooling system carries out systemic circulation, and coolant liquid is divided into two-way flowing：
First via coolant liquid enters exhaust side block jacket by the water main inlet port of block jacket, and coolant liquid is sufficiently mixed
Enter cylinder head jacket from the coolant inlet of cylinder head jacket afterwards, fuel oil burning is taken away in flowing in cylinder head exhaust duct region
Then coolant liquid is introduced spark plug mounting hole region and introduces nasal bridge region through cooling water channel, to spark by the heat of release
Plug installation bore region and nasal bridge region are cooled down, and the cooling liquid outlet for finally flowing through cylinder head jacket flows into air inlet side cylinder block
Water jacket is mixed with the second tunnel coolant liquid；
Secondary water inlet of the second tunnel coolant liquid through block jacket enters the bottom of air inlet side block jacket, with the first via
Coolant liquid be sufficiently mixed after through main water outlet flow out engine.
The bottom of the block jacket is along water (flow) direction undulate shape, and the trough of wave-like is located at single cylinder
The centre position of body, centre position of the wave crest between two neighboring cylinder block, can improve the flow trace of coolant liquid, make
Coolant liquid cooling heat transferring is more abundant, ensure that the cooling effect at each position of engine is identical.
Longitudinal passage section of the block jacket any place is equal, and coolant liquid can be promoted in engine interior flow velocity
Uniformly.
Three groups of coolant inlets, three groups of cooling liquid outlets and three cooling water channels be arranged side by side from left to right, and
The one group of cooling liquid outlet of every group of coolant inlet corresponding thereto is in the figure of eight of upper and lower opening, ensure that each cylinder
Cooling effect is identical.
The present invention has the following advantages：
（1）When coolant temperature is relatively low, only the exhaust side of engine is cooled down, in the premise for ensuring engine reliability
Under, improve the heat engine speed of engine；
（2）The highest exhaust side of preferential cooling engine temperature effectively shortens complete machine heating, to reduce engine
Oil consumption；
（3）The secondary water inlet of block jacket can improve the coolant flow of block jacket air inlet side bottom, can
Avoid the occurrence of flow dead zone；
（4）Since the interface channel sectional area between block jacket and cylinder head jacket is larger, engine water jacket is reduced
Flow resistance, to reduce the performance requirement to water pump；
（5）Go out due to being respectively arranged one group of coolant inlet and one group of coolant liquid on the corresponding cylinder head of each cylinder
Mouthful, it ensure that the cooling effect of each cylinder is identical；
（6）Due to being provided with special cooling water channel in nasal bridge region, cooling can be oriented to nasal bridge region, prevented
Nasal bridge region temperature is excessively high and cracked；
（7）The bottom of block jacket is in wavy, which can improve the flow trace of coolant liquid, make cold
But liquid cooling heat transferring is more abundant, ensure that the cooling effect at each position of engine is identical；
（8）Longitudinal passage section of block jacket any place is equal, and coolant liquid can be promoted in engine interior flow velocity
Uniformly；
In conclusion the present invention has, simple in structure, flow velocity is uniform, flow resistance is small, and each position cooling of engine can be made equal
It is even, and cooling can be oriented to the nasal bridge region between cylinder head exhaust duct.
