The small circulating water channel is arranged in the cylinder cover and the cylinder body, the length of the small circulating cooling channel is shortened, the cooling water flows smoothly, and the cooling effect of the small circulation is improved.
Description
Technical field
The utility model belongs to field of automobile, specially refers to the cooling system of motor.
Background technique
Explosive motor mainly adopts the mode that large and small circulation is switched mutually to cool off at present, described large and small circuit switching utilizes thermostat to control, when the cooling water water temperature is higher than predetermined temperature, thermostat control major cycle work, this moment, cooling water cooled off through radiator; When the cooling water water temperature is lower than predetermined temperature, the work of thermostat control short circle, this moment, cooling water then without the radiator cooling, was only finished circulation at engine interior.Cooling water in the short circle of conventional engines need flow back into the water pump place through the outer bypass line of motor, the water channel at this place is longer, this just makes the cooling water current not smooth, not only can waste the power of water pump, also can have a strong impact on the cooling effect of short circle, because too high temperature causes the damage of components of motor or produces aging distortion, be necessary to design better engine-cooling system for avoiding.
The model utility content
The purpose of this utility model is the engine-cooling system that proposes a kind of good cooling results.
Engine-cooling system of the present utility model comprises the large and small circulation cooling channel that is connected to form by water pump, cylinder body water jacket, cylinder cap water jacket, radiator, fan, water tank, thermostat and connecting pipeline, key is that the water outlet of the cylinder cap water jacket in the described short circle cooling channel communicates with the water inlet of thermostat, the water inlet of the short circle water channel that the auxiliary-valve of described thermostat is interior with being arranged on cylinder cap and cylinder body communicates, and the water outlet of described short circle water channel is communicated with water pump.
Cooling water in the short circle of above-mentioned engine-cooling system need not to flow back into the water pump place through the outer bypass line of motor, but flow back to water pump by the short circle water channel that is arranged in engine cylinder cover and the cylinder body, shortening short circle cooling channel length greatly, make flow of cooling water simultaneously smoothly, increase the flow path of cooling water in engine cylinder-body and cylinder cap on the contrary and got length, thereby improved the cooling effect of short circle.
Described short circle water channel also communicates with the water outlet of machine oil cooler, the water outlet of described water pump communicates with the water inlet of machine oil cooler, like this can also be with the path of short circle water channel as oil cooled system, need not to be provided with separately again the bypass line of oil cooled system, not only reduced cost, make that also the structure of motor is compact more, the convenient layout reduced rate of fault.
Described short circle water channel communicates with the water outlet of machine oil cooler by thermostat, and layout can make full use of the structure of thermostat like this, reduces the opening of engine cylinder cover, and convenient for maintaining.
Described short circle water channel is arranged on the front side of cylinder cap and cylinder body, can make full use of the space of motor like this, shortens the length of short circle water channel, improves the cooling effect of short circle.
Engine-cooling system of the present utility model has shortened the length of short circle cooling channel by the short circle water channel is set in cylinder cap and cylinder body, make flow of cooling water smooth and easy, has improved the cooling effect of short circle.
Description of drawings
Fig. 1 is the structural representation of the cylinder cap part in the engine-cooling system of the present utility model.
Embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
The engine-cooling system of present embodiment comprises by water pump, cylinder body water jacket, the cylinder cap water jacket, radiator, fan, water tank, it is big that thermostat and connecting pipeline are connected to form, the short circle cooling channel, as shown in Figure 1, key is that the water outlet 3 of the cylinder cap water jacket 2 in the described short circle cooling channel communicates with the water inlet of thermostat 8, the auxiliary-valve of described thermostat 8 communicates with the water inlet 4 of short circle water channel 7 in being arranged on cylinder cap 1, short circle water channel 7 in the cylinder cap 1 and the short circle water channel in the cylinder body are arranged on the front side of cylinder cap and cylinder body, and communicate by the backwater hole 5 of cylinder cap front bottom end, the position of backwater hole 5 is between sprocket wheel chamber and cylinder water cavity, and the water outlet of the short circle water channel in the described cylinder body is communicated with water pump.
The short circle water channel 7 of described cylinder cap 1 communicates with the water outlet 6 of machine oil cooler by thermostat 8, and the water outlet of described water pump communicates with the water inlet of machine oil cooler.
The concrete type of cooling of the engine-cooling system of present embodiment is as follows:
1, cooling water is introduced in the cylinder body water jacket under the effect of water pump, enter in the cylinder cap water jacket 2 by the through hole on the cylinder body again, thermostat 8 places are got back to by cylinder head water cover osculum 3 in cylinder cap cooling back, when water temperature is lower than the unlatching temperature of thermostat 8, the main valve of thermostat 8 is closed, auxiliary-valve is opened, cooling water enters in the short circle water channel 7 of cylinder cap 1 inside through the auxiliary-valve of thermostat 8, enter in the short circle water channel of cylinder body by backwater hole 5 again, be back to water pump at last, form lesser circulation.
2, after the water temperature of cooling water reached the unlatching temperature of thermostat 8, the main valve of thermostat 8 was opened, and closes a part of auxiliary-valve simultaneously, and major cycle this moment and short circle carry out simultaneously.Cooling water in the cylinder cap water jacket is divided into two-way, and the main valve of thermostat 8 of leading up to flow into radiator, through finally flowing back into the water pump place after the radiator cooling, forms the major cycle path; Another road flow in the short circle water channel 7 of cylinder cap 1 inside in the cylinder cap by the auxiliary-valve of thermostat 8, enters in the short circle water channel of cylinder body by backwater hole 5 again, is back to water pump at last, forms lesser circulation.
3, after the water temperature of cooling water reaches the standard-sized sheet temperature of thermostat 8, the auxiliary-valve of thermostat 8 is closed fully, have only major cycle work this moment, promptly the cooling water in the cylinder cap water jacket flow into radiator by the main valve of thermostat 8, through finally flowing back into the water pump place after the radiator cooling.
In addition, the cooling water of machine oil cooler all enters into short circle water channel 7 in the cylinder cap 1 by thermostat 8, enters short circle water channel in the cylinder body by backwater hole 5 then, gets back to water pump at last, above-mentioned path all is in opening state always, to guarantee the proper functioning of machine oil cooler.
