Description
Technical field
The present invention relates to a kind of cooling system for vehicle.
Background technique
The water pump structure of existing automobile cooling system mainly have monomer mechanical water pump and two kinds of electric water pump.
Mechanical water pump revolving speed and engine speed are at certain proportionate relationship, when the engine starts, mechanical water pump
It rotates with, is cooled down immediately for engine, engine is cold conditions and does not need to cool down at this time, and premature cooling causes to start
Machine warm-up period extends, and also remains high the power consumption of engine while increasing engine load.
Electric water pump can adjust pump rotary speed in real time by the coolant temperature in the cooling duct of ECU feedback, essence
Really control pump capacity will be come when meeting engine cool demand, but being more than certain power, the volume of electronic water pump itself will
Can be as the increase of power be at geometric increase, and cost can also steeply rise, and not only substantially increase the assembly of engine
Space, also increase engine cost, to reduce the competitiveness of product.
The disadvantages mentioned above of monomer water pump product, has constrained the development of engine.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cooling system for vehicle accurately controlled.
To solve the above problems, the technical scheme is that：A kind of cooling system for vehicle accurately controlled, including hair
Motivation ECU, cooling water pump and cooling duct, the cooling water pump include the electromagnetic clutch water pump and electric water pump being arranged in parallel,
The outlet of electromagnetic clutch water pump and electric water pump is respectively provided with a check valve, and the electromagnetic clutch water pump is by electric control clutch control
System, the electric water pump are controlled by driving motor, and the electromagnetic clutch and the driving motor are electrically connected with Engine ECU
It connects, under the control of Engine ECU, the electromagnetic clutch water pump and the electric water pump can be at whole off-positions or select
One working condition.
Preferably, the electric water pump is low-power water pump.
Preferably, the driving motor is DC brushless motor.
Monomer structure is changed to composite structure, i.e. electromagnetic clutch water pump+low-power electro water pump by the present invention, takes parallel connection
Form；When the engine starts, electromagnetic clutch water pump is in off-position, low speed rotation, electric water air pump inoperative, engine
It is rapidly heated, saves warm-up period；When engine is when small-power is run, electromagnetic clutch water pump is still in power-off shape
State is mainly accurately cooled down by the temperature of ECU detection coolant liquid to control electric water pump；When engine is in high-power operation
The heat of generation is more, and electromagnetic clutch water pump is at energized state, high speed rotation, at this time electric water air pump inoperative；This product
Parallel-connection structure not only shortens engine warm-up time, but also realizes accurately controlling, reducing product power consumption, promoted for cooling system
Product quality, also controls product cost.
Detailed description of the invention
Fig. 1 is the overall structure diagram in the embodiment of the present invention.
Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.
In the description of the present invention, it is to be understood that, term " first ", " second " are used for description purposes only, and cannot
It is interpreted as indication or suggestion relative importance or implicitly indicates the quantity of indicated technical characteristic.In description of the invention
In, the meaning of " plurality " is two or more, unless otherwise specifically defined.In the description of the present invention, it needs
Illustrate, unless otherwise specified and limited, term " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be
Mechanical connection or electrical connection, the connection being also possible to inside two elements can be directly connected, and can also pass through intermediary
It is indirectly connected, for the ordinary skill in the art, can understand the concrete meaning of the term as the case may be.
As shown in Figure 1, the preferred embodiment of the present invention is：A kind of cooling system for vehicle accurately controlled, including start
Machine ECU, cooling water pump and cooling duct, the cooling water pump include the electromagnetic clutch water pump and electric water pump being arranged in parallel, electricity
The outlet of magnetic clutch water pump and electric water pump is respectively provided with a check valve, and the electromagnetic clutch water pump is controlled by electric control clutch,
The electric water pump is controlled by driving motor, and the electromagnetic clutch and the driving motor are electrically connected with Engine ECU,
Under the control of Engine ECU, the electromagnetic clutch water pump and the electric water pump can be at whole off-positions or select a work
Make state；The electric water pump is low-power water pump, and driving motor is DC brushless motor.
When electromagnetic clutch pump working, electric water air pump inoperative, coolant liquid flows through electromagnetic clutch water pump from A point, passes through
Check valve 1 reaches B point, into engine-cooling system；When electric water pump work, electromagnetic clutch water pump low speed rotation is cooling
Liquid flows through electric water pump from A point, and by check valve 2, reach B point has a small amount of coolant liquid from electricity into engine-cooling system
Magnetic clutch water pump enters engine-cooling system.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart from the technical program design under the premise of it is any obviously replace it is within the scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand the improvements of the present invention compared with the existing technology, this
Some attached drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, the element that those of ordinary skill in the art should be aware that these are omitted also may make up the contents of the present invention.
