In addition, be fixed with fan main body 15 described later, on the other hand, be fixed with the impeller 16 of pump 13 in the rearward end of rotating shaft 14 at the leading section of the rotating shaft 14 of motor 12.
Fan main body 15 by fixed head 15b, roughly the pot shape the 15c of hub portion and a plurality of blade 15d constitute (only illustrating 1 blade), this fixed head 15b is installed on the leading section of the rotating shaft 14 that has connected motor field frame 12a with nut 15a, the 15c of this hub portion is integrally formed with the state that embedding is formed with this fixed head 15b, and this blade 15d extends to radial outside from the peripheral part of the 15c of this hub portion.
Pump 13 is made of pump case 13b and impeller 16, and this pump case 13b has in inside becomes the pump chamber of coolant path 13a, and this impeller 16 usefulness nut 13c are installed on the rearward end of the rotating shaft 14 of the end plate 12j that connected motor 12 and pump case 13b.
In addition, be formed with a plurality of upright tabular blade 16a that are located on the pump chamber 13a on the impeller 16.
A plurality of positions of the rearward end periphery of pump case 13b are fixed on the pump case 13b and end plate 12j of motor 12 by screw 13d.
In addition, near the center of the pump case 13b that rotating shaft 14 is run through, be folded with and simplified illustrated known mechanical sealing member 13e, seal pump chamber 13a thus.Axial opposite side at pump case 13b is provided with the ingate 13h that is connected with tube connector 9i, is provided with the outlet 13h that is connected with tube connector 9j in the radial side of pump case 13b.
In addition, be formed with on rotating shaft 14 from nut 15a in its cooling holes 17 of forming of length range cut roughly, this cooling holes 17 is connected with pump chamber 13a.In addition, the shape of cooling holes 17 can suitably be set.
In addition, though omitted diagram, be provided with carriage on pump integral motor fan 10, this carriage is used for fixing the fan stay of the fan guard that is installed on heat exchanger 7 rear surfaces.
So, by on the rotating shaft 14 that impeller 16 is incorporated into motor 12 and electrical motor fan 11 and pump 13 are coupled together.
Thus, when rotating shaft 14 is subjected to vehicle ' wind and the revolving force of the fan main body 15 that produces drives or motor 12 drives and when axis rotates, electrical motor fan 11 plays the effect of the fan of main radiator 2 of cooling and secondary radiator 6 under the pressure wind action that produces along with the rotation of fan main body 15, on the other hand, pump 13 plays and will flow into the effect that cooling water (shown in the chain-dotted line of Fig. 2) the pump chamber 13a is delivered to the pump of outlet opening 13h from ingate 13g along with the rotation of impeller 16.
At this moment, can be full of the cooling holes 17 of rotating shaft 14 with the cooling water of pump chamber 32a and cool off this rotating shaft 14, and then can be internally with whole motor 12 coolings.
Therefore, the brush motor that has that can rise to the easy temperature of slip because of brush 12j effectively cools off, and is very practical.
One example of the drive controlling of the pump 13 in the pump integral motor fan 10 then, is described.In addition, below yes is carried out repeatedly with specific time interval during stopping beginning to start from engine by the outer main control unit of the figure that is electrically connected with information of vehicles network (CAN), control unit of engine etc. in Shuo Ming control, thus control pump integral motor fan 10.
As shown in Figure 3, at first, in step S1, detect the cooling water temperature of water-cooled intercooler cooling circuit R2 by temperature sensor C1 (with reference to Fig. 1).
In addition, in embodiment 1, temperature sensor C1 is arranged on the outlet side of water-cooled intercooler 5, but this is provided with the position and can suitably sets.
Then, in step S2, judge whether be lower than setting X1,, then turn back to step S1,, then move to step S3 if more than the setting X1 if be lower than setting X1 at the detected cooling water temperature of step S1.
In step S3, the rotating speed by the rotating shaft 14 (fan main body 15) that is installed on the figure testing pump integral motor fans 10 such as speed probe outward on the rotating shaft 14 moves to step S4 then.
In step S4, judge whether the rotating speed at the detected rotating shaft 14 of step S3 is lower than setting X2, if be lower than setting X2, then move to step S5, if more than the setting X2, then move to step S7.
In step S5, (hereinafter referred to as the auxiliary quantity) in shortage according to calculate the rotating speed that will reach the needed rotating shaft 14 of desired pump performance at the rotating speed of the detected rotating shaft 14 of step S3 moves to step S6.
In step S6, with with the corresponding output power drive motor 12 in shortage of the rotating speed of calculating at step S5, utilize the driving of this motor 12 and be subjected to vehicle ' wind and the revolving force of the fan main body 15 that produces makes rotating shaft 14 rotations, thus driving pump 13, afterwards, turn back to step S1.
On the other hand, in step S7, only depend on the revolving force of the fan main body 15 that is subjected to vehicle ' wind and produces to make rotating shaft 14 rotations, thereby driving pump 13 afterwards, turn back to step S1.
In addition, setting X1, setting X2 can suitably set, and set setting X1 low more, and set setting X2 high more, and then the running efficiency of motor 12 is high more.
So, in embodiment 1, detect the cooling water temperature (step S1) of water-cooled intercooler cooling circuit R2, at cooling water temperature is that setting X1 is when above, detect the rotating speed (step S2 → step S3) of fan main body 15 (rotating shaft 14), when this rotating speed is lower than setting X2, vehicle ' wind a little less than, the rotating speed of rotating shaft 14 is not enough to realize desired pump performance, calculate the auxiliary quantity of motor 12, utilize vehicle ' wind and motor 12 to come driving pump 13 (step S4 → step S5 → step S6) then.
Thus, simultaneously driving pump 13 and electrical motor fan 11, with pump 13 make cooling water circulation on one side, cool off with secondary radiator 6 on one side.
In addition, can utilize vehicle ' wind to come driving pump 13, thereby the power consumption of motor 12 can be suppressed lower.

On the other hand, be setting X2 when above at the rotating speed of fan main body 15 (rotating shaft 14), vehicle ' wind is stronger, and the rotating speed of rotating shaft 14 is enough to realize desired pump performance, only depends on vehicle ' wind to come driving pump 13 (step S4 → step S7).
Thus, simultaneously driving pump 13 and electrical motor fan 11, with pump 13 make cooling water circulation on one side, cool off with secondary radiator 6 on one side.
In addition, can only utilize vehicle ' wind to come driving pump 13, can eliminate the power consumption of motor 12, can improve simultaneously the durability of brush 22g etc.In addition, also can improve the quiet performance of vehicle.
Therefore, in embodiment 1, make the cooling water circulation by one side driving pump 13, with secondary radiator 6 cool off on one side, thereby can make the cooling water temperature of water-cooled intercooler cooling circuit R2 be lower than setting X1 all the time, thereby can improve the heat exchange efficiency of water-cooled intercooler 5.Thus, even turbocharger 8 starts and the cooling water temperature of water-cooled intercooler cooling circuit R2 is risen, can after this turbocharger 8 has just stopped, this cooling water temperature be reduced fast, the heat exchange efficiency of the water-cooled intercooler 5 in the time of can improving turbocharger 8 and start once more thereafter.That is, especially can carry out repeatedly at short notice turbocharger 8 startup, stop under such situation its effect of performance.
In addition, the drive controlling of said pump 13 only is an example, and the present invention is not limited to this drive controlling.
For example, in embodiment 1, cooling water temperature be lower than setting X1 during, do not need driving pump 13, and, even vehicle ' wind has driven pump 13, can not impact, therefore yet, can pump 13 not carried out drive controlling, but if cooling water temperature is lower than setting X1, and vehicle ' wind then also will be considered to control the rotating speed that reduces rotating shaft 14 with motor 12 when excessive.
In addition, can use threshold value such as the temperature, the speed of a motor vehicle etc. of turbocharger gas return path R3 as pump 13 actions.
Other, pump integral motor fan 10 is identical with the engine of known band turbocharger as the work of fan, is described.
At this, to adopting vehicle of the present invention to carry out bench test, the result is: in common car speed zone, be subjected to vehicle ' wind and the revolving force (rotating speed) of fan main body 15 when producing is enough to easily drive the motor (being equivalent to the above motor of DC12V, 100W) of present situation, the pump (being equivalent to the pump about DC12V, 50W) of present situation.
Therefore, can think, only can not obtain vehicle ' wind, can not expect in the vehicle utmost point low speed driving of fan main body 15 rotations or the situation of vehicle in stopping under, assist rotating shaft 14 with motor 12, with driving pump 13, the provable power saving effect that can fully obtain motor 12.
In addition, the specification of testing employed motor 12 is and identical in the past DC12V, 200W motor, even under the situation that can not obtain vehicle ' wind, only depend on motor 12 also can be without a doubt drive fan main body 15 and pump 13 simultaneously, do not need specification that changes by motor 12 etc., implement easy yet.
Then, description effect.
As discussed above, in the pump integral motor fan 10 of embodiment 1, the heat exchanger cooling of being located at the vehicle cooling circuit is coupled together with pump 13 with electrical motor fan 11 and coolant circulation, can utilize the revolving force of the fan main body 15 of the electrical motor fan 11 that is subjected to vehicle ' wind and produces to come driving pump 13, therefore, can realize the miniaturization and the reduction power consumption of pump 13.
In addition, be engaged in by impeller 16 on the rotating shaft 14 of motor 12 of electrical motor fan 11, this electrical motor fan 11 and pump 13 are coupled together, therefore, do not need change that the two is designed significantly, can realize commercialization easily pump 13.
