One important directions of motivation development.
Gas recirculation system (Exhaust Gas Recirculation) abbreviation EGR, refer to that internal combustion engine after combustion will
Discharge gas a part import inlet manifold again, into combustion chamber after make the technology that it burns once again.Its main purpose is
The nitrogen oxides reduced in discharge gas can improve fuel firing rate simultaneously, make waste gas pollutant output quantity total in discharging relative
Reduce.In addition, engine is at work, many driving parts are all to make high speed relative motion under the gap of very little, therefore
There must be lubricating oil to be lubricated the driving parts.
Cooling system is that the optimization design of cooling system is to start an important factor for influenceing engine reliability and emission performance
One important step of machine design.At work, the machine oil in waste gas and machine oil refrigerating module in egr system is both needed to engine
Cooled down, the mode of traditional type of cooling generally use external pipeline or the diversion from cylinder cover water jacket, such water inlet knot
Structure is more complicated, difficult arrangement, and manufacturing cost is higher.
The existing type of cooling is that cooling duct is directly opened up on cylinder body, and in channel blockage, maintenance difficulty is larger,
Even need to change whole engine cylinder-body, maintenance cost is higher.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of diesel engine cooling system, existing so as to solve
Engine-cooling system inconvenient maintenance, the problem of maintenance cost is higher when blocking.
The utility model solves above-mentioned technical problem by following technological means：
A kind of diesel engine cooling system, is plugged with the cooling water pipe for water cooling in engine cylinder-body, and
The groove for accommodating the cooling water pipe insertion is offered on cylinder body, inlet is provided with one end of cooling water pipe and is set in the other end
There is liquid outlet, the cooling water pipe further respectively has on cooling water pipe and is used for for coiled pipe and along the cylinder body contour extension
Connect the egr system outlet pipe and machine oil refrigerating module outlet pipe of egr system inlet and machine oil refrigerating module inlet.
So, by opening up vertical groove on engine cylinder-body, and cooling water pipe is inserted directly into a groove, and it is cold
But water pipe is using thin-wall steel tube or the higher tinfoil paper pipe of heat transfer efficiency, groove open up shape and cooling water pipe be adapted so as to
Fully it is bonded and contacts with cylinder body in cooling water pipe, coolant is entered by mouth tonight, and is circulated along serpentine-like cooling water pipe, around
The contour extension of cylinder body is exported by liquid outlet after one week, in the coolant process of circulation, coolant by egr system outlet pipe and
Machine oil refrigerating module outlet pipe branches to egr system inlet and machine oil refrigerating module inlet so as to waste gas and machine oil respectively
Cooled down.
Further, the egr system outlet pipe is arranged on the top bending place of cooling water pipe.
Further, the bottom of the cylinder body is additionally provided with jack.
Further, machine oil refrigerating module water out adapter is provided with the bottom bending place of cooling water pipe, and the machine oil is cold
But module water out adapter can be inserted into the jack.
Further, described machine oil refrigerating module outlet pipe is connected by adapter sleeve and machine oil refrigerating module water out adapter
Connect.
Further, described adapter sleeve casting is on cylinder body.
The beneficial effects of the utility model：By using the grafting form of cooling water pipe and cylinder body so that cylinder body and cooling
System separates, and in the case where cooling system individually blocks, directly can take out cooling water pipe, repair and change all very convenient money
Fast, and maintenance cost is relatively low, simple in construction, easy to use, easy to spread.
Brief description of the drawings
Fig. 1 is the utility model overlooking the structure diagram；
Fig. 2 is the utility model main structure diagram.
Embodiment
The utility model is described in detail below with reference to accompanying drawing：
As shown in Figure 1-2：
A kind of diesel engine cooling system, the cooling water pipe 2 for water cooling is plugged with engine cylinder-body 1, and
Offered on cylinder body 1 and accommodate the groove 3 that the cooling water pipe 2 inserts, be provided with one end of cooling water pipe 2 inlet 4 and
The other end is provided with liquid outlet 5, and the cooling water pipe 2 is gone back for coiled pipe and along the contour extension of cylinder body 1 on cooling water pipe 2
It is respectively provided with egr system outlet pipe 6 and machine oil the cooling mould of connection egr system inlet and machine oil refrigerating module inlet
Block outlet pipe 7.
So, by opening up vertical groove 3 on engine cylinder-body 1, and cooling water pipe 2 is inserted directly into groove 3, and
And cooling water pipe 2 is mutually fitted using the higher tinfoil paper pipe of thin-wall steel tube or heat transfer efficiency, the shape that opens up of groove 3 with cooling water pipe
It should be contacted in order to the fully fitting of cooling water pipe 2 and cylinder body 1, coolant is entered by mouth tonight 4, and along serpentine-like cooling water
