Description

Electric control cooling system of engine

Technical field

The utility model relates to a kind of engine-cooling system, belongs to technical field of cooling system structures.

Background technique

Water pump 13 in the vehicular engine cooling system originally mostly is to adopt mechanical water pump (as shown in Figure 1), as long as engine running, water pump 13 is just rotation under the drive of belt 14, and no matter the temperature of cooling liquid is a height or low, expansion kettle 15 connects by the top of pipeline one end with radiator 11, the other end connects with the lower end of radiator 11, and after the temperature of cooling system raise, a spot of cooling liquid can temporarily be stored in the expansion kettle 15; When cooling system needs to add cooling liquid for a certain reason, need to inject from expansion kettle 15.The normal working temperature of motor leans on thermostat and radiator 11 and radiator fan 12 to regulate assurance, and like this, if the thermostat that has damages, the engine warms time in winter is elongated; Car is when running at high speed in addition, and the temperature of motor can reduce, and has accelerated the wearing and tearing of friction pair; Simultaneously, be engraved in rotation during water pump, also consumed the power of motor in vain, improved oil consumption; And when mechanical water pump is installed, need on engine cylinder-body, reserve the mounting point, so not only increase operation, also can raise the cost.

Summary of the invention

The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of and can guarantee the normal temperature of motor, the electric control cooling system of engine that reduces oil consumption, reduces processing technology, reduces cost.

Engine-cooling system of the present utility model is achieved through the following technical solutions:

Electric control cooling system of engine is characterized in that comprising the electric water pump 3 that is connected in series between motor 4 and the radiator 1 that has radiator fan 2, and expansion kettle 5 is connected with the top of radiator 1 by pipeline one end, and the other end is connected with the bottom of radiator 1; Electric water pump 3 is provided with control circuit, control circuit comprises controller 6, the signal of controller 6 input control end is connected with cylinder temperature sensor 7, water tank temperature sensor 8 and the AIR COND SIG Air Conditioner Singnal 9 on the radiator 1 on the motor 4 respectively, AIR COND SIG Air Conditioner Singnal 9 comes from air-conditioning switch, as long as open air-conditioning, an electrical signal input controller 6 is just arranged, and the signal output control terminal of controller 6 is connected with electric water pump 3, radiator fan 2 respectively.

Electric control cooling system of engine of the present utility model, adopt electric water pump to replace mechanical water pump, electric water pump is " changeing as required ", guarantee the motor normal working temperature, reduced kinetic equation loss, reduced oil consumption, for having turbo charged motor, also can to stall the time, lower the temperature, prolong the life-span of pressurized machine to pressurized machine; After having cancelled mechanical water pump, engine cylinder-body does not just need to reserve the water pump mounting point, has reduced manufacturing procedure, reduces cost, and the electric water pump that is made of one can be fixed on the convenience outside the cylinder body, and water pipe gets final product with the motor connection.

Embodiment

Following with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.Motor 4 and radiator 1,

Embodiment 1

The electric control cooling system of engine of present embodiment is with reference to figure 2, Fig. 3, comprise the electric water pump 3 that is connected in series between motor 4 and the radiator 1 that has radiator fan 2, expansion kettle 5 is connected with the top of radiator 1 by pipeline one end, and the other end is connected with the bottom of radiator 1; Electric water pump 3 is provided with control circuit, control circuit comprises controller 6, the signal of controller 6 input control end is connected with cylinder temperature sensor 7, water tank temperature sensor 8 and the AIR COND SIG Air Conditioner Singnal 9 on the radiator 1 on the motor 4 respectively, AIR COND SIG Air Conditioner Singnal 9 comes from air-conditioning switch, as long as open air-conditioning, an electrical signal input controller 6 is just arranged, and the signal output control terminal of controller 6 is connected with electric water pump 3, radiator fan 2 respectively.

Working principle: the running of water pump 3 is by temperature controlled, rather than drives by dynamo belt.When the water tank temperature sensor 8 on cylinder temperature sensor on the motor 47 or the radiator 1 detect temperature reach certain after, controller 6 just starts electric water pump 3 work, and temperature is controlled in the normal range of operation; If it is slow that temperature reduces, controller 6 can start radiator fan 2, accelerates the heat radiation of cooling liquid.After if the temperature transducer 8 on the radiator 1 reaches certain temperature, controller 6 control radiator fan 2 work separately.Summer the external temperature height, controller 6 can the corresponding operating time that prolongs electric water pumps 3 and radiator fan 2, to guarantee that motor is in the normal working temperature scope.Certainly, receive AIR COND SIG Air Conditioner Singnal 9 after, also can lengthen working hours accordingly.

The electric control cooling system of engine of present embodiment, adopt electric water pump to replace mechanical water pump, like this, electric water pump is " changeing as required ", has guaranteed the normal working temperature of motor, reduced kinetic equation loss, reduced oil consumption, for having turbo charged motor, can also be to stall the time, lower the temperature to pressurized machine, prolong the life-span of pressurized machine; After having cancelled mechanical water pump, engine cylinder-body does not just need to reserve the water pump mounting point, has reduced manufacturing procedure, reduces cost, and the electric water pump that is made of one can be fixed on the convenience outside the cylinder body, and water pipe gets final product with the motor connection.
