Description
Technical field
The present invention relates to a kind of cooling system of vehicle, particularly relate to a kind of cooling system of vehicle with variable flow pump.
Background technique
As shown in Figure 1, one existing cooling system of vehicle 1 comprises the pump 12 that water tank 14, one cooling liquid 15 that this water tank is interior that is equipped with the cooling liquid 15 that is used for cooled engine 11 is delivered to this motor, reaches the thermostat 13 of flow in a control cooling liquid 15 reflow tanks.
Consult Fig. 2, this thermostat 13 comprises a hollow body 131, and this body 131 has a water inlet 132, one first water outlet 133, and a sectional area is less than second water outlet 134 of this first water outlet 133.Be provided with a wax chamber 135 with a switch valve 136 in this body 131.
Should have the temperature that cooling system of vehicle 1 utilizes the cooling liquid 15 that flows out this motor 11 now, and make the wax chambers 135 in this thermostat 13 control this switch valve 136 because of the effect of expanding with heat and contract with cold.When the temperature of this cooling liquid 15 was hanged down, this cooling liquid 15 flowed back to this water tank 14 from the second less water outlet 134 of this sectional area; And when the temperature of this cooling liquid 15 was high, this cooling liquid 15 flowed back to this water tank 14 from bigger first water outlet 133 of this sectional area.But should existing cooling system of vehicle 1 and during these cooling liquid 15 low temperature at these motor 11 high rotating speeds, because this thermostat 13 still is in this second water outlet 134, makes the flow resistance of this cooling liquid 15 increase and then cause the power consumpiton of this motor 11 to increase.And the flow that should have the pump 12 of cooling system of vehicle 1 now is only complied with these motor 11 rotation speed change, do constant temperature control to this motor 11 and be not easy, and then influence the life-span of this motor 11.
Also there is motor-drive pump to replace existing pump 12 with changeable flow, cause when the low temperature power consumpiton of this motor 11 to increase to overcome this existing cooling system of vehicle 1, and it is slow to overcome the existing hot wax formula of thermostat reaction velocity, can't do real-time flow adjustment according to the engine load state, and then this motor 11 is carried out constant temperature control, yet, short, difference power of motor-drive pump life-span and to cost an arm and a leg also be significant drawback on it is used.
Summary of the invention
Therefore, purpose of the present invention is promptly providing a kind of cooling system of vehicle with variable flow pump, reduces because of flow resistance that cooling water causes, and then improves the power consumpiton of motor.In addition, the present invention makes motor decide under the rotating speed the still flow of may command cooling liquid, and does different coolings according to different loads, and then makes engine temperature near constant temperature, and the endurance life that improves motor helps the lifting of Engine Durability.
So cooling system of vehicle of the present invention is used to control the temperature of vehicle motor, comprises the variable flow pump that a ccontaining water tank, that is used for the cooling liquid of cooled engine is used for cooling liquid is delivered to this motor, and a control unit.
This variable flow pump comprises that one has a water inlet, and the hollow shape housing, of a water outlet is placed in this enclosure interior, and the control valve, that is placed in this enclosure interior rotationally for wheel blade, that this motor drove is received from the signal of signal processor of this control unit to drive the driver element that this control valve rotates.
This control unit comprises that one is used for Temperature Detector, a signal processor that is connected with this Temperature Detector of detection of engine temperature signal, this signal processor is used to handle the temperature signal that this Temperature Detector obtains, and exports corresponding pilot signal to control the flow that this variable flow pump is delivered to the cooling liquid of motor.
Effect of the present invention is to cooperate with this variable flow pump the control of control unit again, and then the flow of control cooling liquid, reaches the control engine temperature and reduces the purpose that engine power consumes.
