Description
Technical field
The utility model relates to the engine cooling water circulation system of automobile.
Background technique
The effect of engine-cooling system is that the heat that heated component absorbs is in time distributed, and the assurance motor is worked under only state of temperature.The cooling system of motor is divided into air-cooled and water-cooled, and cooling water recirculation system belongs to the part of engine water-cooling.
Cooling water recirculation system is divided into two heat radiation circulations: one is the major cycle of cooled engine, and another is the warm braw circulation in the car, and the major cycle of cooled engine can be divided into major cycle and short circle two-part.
In the engine operation process, when coolant temperature does not reach thermoregulator unlatching temperature (majority is 80～90 ℃), have only short circle participation work in the engine cooling water circulation system, this moment, cooling liquid was without water tank; When the temperature of cooling liquid reached the unlatching temperature of thermoregulator, major cycle and short circle all participated in work, and this moment, cooling liquid will be passed through water tank.
In the big short circle of engine-cooling system, cooling liquid is by water pump, the cylinder body of flowing through, cylinder cap, and carry out big or small loop control by thermoregulator, the guide functions by water pipe circulates again.The water pump of existing motor car engine is installed on the cylinder body, and thermoregulator is installed on the intake manifold, enters thermoregulator by the road after the cooling liquid on the cylinder cap in each water jacket is compiled.This structure makes the dried up pump close together in the cooling liquid outlet position on the cylinder cap, flow and the flow velocity of cooling liquid in each water jacket on the cylinder cap is inconsistent, even cooling liquid just do not finished the inner loop of motor through the hot-zone part of cylinder cap inside fully by water outlet, thereby influenced the cooling effect of motor.
The model utility content
It is more even that the purpose of this utility model provides a kind of flow and flow velocity of the cooling water that passes through each water jacket of cylinder cap of making, thereby reach the engine cooling water circulation system of better cooling effect.
For achieving the above object, the utility model provides a kind of engine cooling water circulation system, include the water jacket on water pump, water tank, thermoregulator and cylinder body and the cylinder cap, water pump is installed on the cylinder body, the feed-water end of water pump links to each other by intake pipe with the waterexit end of water tank, the entrance point of thermoregulator is connected with the water outlet of cylinder cap upper water sleeve, between thermoregulator and water tank, be connected with the major cycle pipeline, between thermoregulator and water pump, be connected with the short circle pipeline, the water outlet of cylinder cap upper water sleeve is arranged on away from the water pump end, and thermoregulator is installed in the position of this water outlet.
Adopt the technical solution of the utility model, the dried up pump in the position of the water outlet of cylinder cap upper water sleeve is far away more, then on the cylinder cap in each water jacket the pressure of cooling liquid more aligned, the cooling liquid of coming from cylinder body each water jacket on the cylinder cap of can flowing through more fully, the flow of cooling liquid, flow velocity reach balanced easily in each water jacket, make the hot-zone of cylinder cap can obtain cooling off more timely, thereby improve the cooling effect of whole motor.
Description of drawings
Accompanying drawing is a composition schematic representation of the present utility model;
Among the figure: 1. water pump; 2. water tank; 3. thermoregulator; 4. cylinder body; 5. cylinder cap; 6. intake pipe; 7. water outlet; 8. major cycle pipeline; 9. short circle pipeline; 10. the warm braw circulatory system.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, engine cooling water circulation system described in the utility model, has water pump 1, water tank 2, water jacket on thermoregulator 3 and cylinder body 4 and the cylinder cap 5, water pump 1 is installed on the cylinder body 4, the feed-water end of water pump 1 links to each other by intake pipe 6 with the waterexit end of water tank 2, the entrance point of thermoregulator 3 is connected with the water outlet 7 of cylinder cap 5 upper water sleeves, between thermoregulator 3 and water tank 2, be connected with major cycle pipeline 8, between thermoregulator 3 and water pump 1, be connected with short circle pipeline 9, the water outlet 7 of cylinder cap 5 upper water sleeves is arranged on away from water pump 1 end, and thermoregulator 3 is installed in the position of this water outlet 7.
The dried up pump 1 in the position of the water outlet 7 of cylinder cap 5 upper water sleeves is far away more, then on the cylinder cap 5 in each water jacket the pressure of cooling liquid more aligned, from can flow through more fully each water jacket on the cylinder cap 5 of the cooling liquid of cylinder body 4, the flow of cooling liquid, flow velocity reach balanced easily in each water jacket, make the hot-zone of cylinder cap 5 can obtain cooling off more timely, thereby improve the cooling effect of whole motor.
As shown in drawings, be connected with the warm braw circulatory system 10 between thermoregulator 3 and short circle pipeline 9, when needing, the heat that produces in the time of can utilizing engine operation is sent hot blast in car.
During work, when the coolant temperature of the thermoregulator 3 of flowing through does not reach setting value, the amount of the required cooling liquid that holds on engine is little, valve between thermoregulator 3 and the major cycle pipeline 8 is in closed condition, this moment, the water circulation system of motor had only short circle participation work, and cooling liquid is without water tank 2; When the coolant temperature of the thermoregulator 3 of flowing through reaches setting value, the amount of the required cooling liquid that holds on engine increases, valve between thermoregulator 3 and the major cycle pipeline 8 is opened, large and small circulation in the engine water circulatory system all participates in work, cooling liquid will be passed through water tank 2, the fan of water tank 2 can carry out air-cooled to the cooling liquid through water tank 2 according to the starting that imposes a condition.The cooling liquid part that comes out from thermoregulator 3 enters short circle pipeline 9 after through the warm braw circulatory system 10 again, when needing warm braw in the car, opens the heater switch of operator cabin, and the hot blow that fan produces during with engine operation advances in the car.
