Embodiment
In Fig. 1, show the dual blower 1 that is used for heat exchanger 2 by of the present invention with plan view.Said heat exchanger 2 is also referred to as heat exchanger, such as the coolant chiller of routine that is provided for carrying out engine cooling usually that is Motor Vehicle.Said dual blower 1 has two fans 4,5, and wherein driven first fan 4 is installed on the motor in known manner.Said motor is schematically represented through square 6 in Fig. 1.5 in said second fan is installed on the set bearing support 7, and this bearing support is schematically represented through circle in Fig. 1.So arranged said two fans 4,5, made it preferably on a unique position, contact with each other on the circumference at the center (intersection of diagonal) of the heat exchanger 2 of said rectangle.This position delivery areas mode with dotted line in Fig. 1 is in other words represented with A.
Now,, directly drive said second fan 5, thereby 5 generations are forced to drive for said second fan through said first fan 4 that drives by motor 6 by the present invention's regulation.Said second fan 5 is easily with 4 runnings of said first fan.Through the together running of said second fan 5 that freely rotates, can abandon now the in the past necessary independent electric drive unit that is used for second fan 5 in other words motor and through simple supporting position with its replacement.Through this design, approximately can save be used for said second fan 5 otherwise the expense of necessary second motor 3/4ths.But about 1/4th of the expense of being saved is born the overhead that is used for the structural measure on bearing support 7 and two fans 4,5.In addition, advantageously, can abandon the way of two blowers 4,5 of design in a common framework.
Pressure for said second fan 5 drives, and exists kinds of schemes for this reason.Common ground is to be in said fan 4, the transmitting element between 5 10, and this transmitting element 10 is born the work to said second fan 5 of the transmission of torque of said first fan 4.This transmitting element 10 is configured in by setting of the present invention on the circumferential surface 12 of circumferential surface 11 and said second fan 5 of said first fan 4 at this in other words.Use with enlarged view like Fig. 2 and to see from the front and to be shown specifically the said delivery areas A, this transmitting element 10 can be configured to tooth portion, be used for the first tooth portion 15 of said first fan 4 and be used for the form of the second tooth portion 16 of said second fan 5.By means of said transmitting element 10 tooth portion 15,16 in other words, can peripheral force and normal force as far as possible noiseless be delivered on said second fan 5 from said first fan 4.Not only constructing tooth portion 15,16 respectively on the circumferential surface 11 of said first fan 4 but also on the circumferential surface 12 at said second fan 5, two that then exist driving mechanism are engaged to central each other gear.
Just the schematic representation of delivery areas A was shown specifically with the sight line of the circumferential surface 11 of investing said fan 4 like Fig. 3, the profile of said tooth portion 15,16 can be equivalent to the profile of gear at this.But also can be just the schematic representation of delivery areas A is shown specifically with the sight line of the circumferential surface 11 of investing said fan 4 like Fig. 2, the tooth portion 15 with corresponding tooth that staggers of along the circumferential direction staggering that replaces for said profile setting.Then also can be configured to the tooth portion 16 of said second fan 5 with the mode of complementation.
The said piecewise at least of each fan 4,5 is that columniform circumferential surface 11,12 surrounds its blade 7,8 in the outside, and therefore it also can be called in addition or fan belt.Said fan 4,5 is axial flow fan preferably, and said axial flow fan is because columniform circumferential surface 11,12 also can be called side face fan (Mantell ü fter).Said tyre 11,12 operated by rotary motion that blade 7,8 is surrounded are used for reducing the fans air swirl of blade 7,8 in other words.
In a kind of change scheme; Said transmitting element 10 also can be made up of first circumferential element 21 that said first circumferential surface 11 is surrounded and second circumferential element 22 of giving said second circumferential surface 12, and said first circumferential element 21 and second circumferential element 22 then can be connected and/or by means of form fit connection realization transmission of torque by means of friction.Therefore in pressing the mode of execution of Fig. 5; Said first and second circumferential element 21,22 can by belt component in other words rubber element 25,26 constitute, said belt component in other words rubber element 25,26 correspondingly the circumferential surface 11,12 through said fan 4,5 come tensioning and then with slight extruding ground each other against mode connect the transmission of torque that realizes from driven first fan 4 to said second fan 5 through friction.
Another kind of scheme is; The form of the friction layer that said first and second circumferential element 21,22 are configured to not be shown specifically, said friction layer correspondingly be applied on the said circumferential surface 11,12 as the second layer to a certain extent and then equally the extruding through said two circumferential surfacies 11,12 cause that friction connects and causes the transmission of torque from driven first fan 4 to said second fan 5 thus.Usually, said fan 4,5 is together with all being made of plastics in addition.Said friction layer is such as can easily spraying on the said circumferential surface 11,12.
Also it is contemplated that; As shown in Figure 6 the same; For said first and second circumferential element 21,22 are provided with Toothed belt 27,28; Said Toothed belt 27,28 comes tensioning and in the middle of the outside is engaged to each other with its flank profil, realizes transmission of torque so that can connect through form fit through the circumferential surface 11,12 of said fan 4,5.Also can replace said Toothed belt and corresponding profile itself is applied directly on the said circumferential surface 11,12.Can be arranged on the profile layer as tooth portion 15,16 that exemplarily illustrates in Fig. 3 and 4, said profile layer is applied on the said circumferential surface 11,12 and can connects through form fit realizes transmission of torque for this reason.Said profile layer can spray on the said circumferential surface 11,12 with simple methods, and said circumferential surface 11,12 is then such as the structure that has by Fig. 3 and 4.
