Definitions
- the present invention relates to a double fan for a heat exchanger, in particular coolant radiator of a motor vehicle, having a first fan and a second fan.
- double fan for motor cooling of motor vehicles. These generate an air flow, which then serves to cool a heat exchanger, in particular coolant radiator for motor vehicles.
- the double fan is characterized by optimum utilization of the cooling to be cooled
- the structure of the double fan has hitherto been such that a separate electric motor is provided for each fan.
- the double fan according to the invention for a heat exchanger, in particular coolant radiator of a motor vehicle in contrast, has the advantage of a significantly simplified and more compact design and, in particular, that the production costs can be greatly reduced. So can be dispensed with a previously required second electric motor.
- the noise development of the double fan can also be reduced overall.
- a transmission element may be formed by a first toothing formed on the lateral surface of the first fan and a second toothing correspondingly formed on the lateral surface of the second fan, both of which mesh with one another for torque transmission.
- a good torque transmission can also be achieved if the transmission element is formed by a first peripheral element surrounding the first lateral surface and a second peripheral element surrounding the second lateral surface, both of which allow torque transmission by means of frictional engagement and / or positive engagement.
- the first and second torquessele- element consist of belt or rubber elements, which are stretched over the lateral surface of the fan and both adjacent to each other by frictional allow torque transmission.
- first and second circumferential element may consist of friction coatings, which on the lateral surfaces of the first and second circumferential element
- the first and second peripheral element consist of toothed belts, which are stretched over the lateral surface of the fan and outside engage with their profile into each other and allow by positive engagement torque transmission.
- first and second peripheral element may consist of profile coatings, which on the lateral surfaces of the first and second peripheral element
- FIG. 1 shows a simplified plan view of the double blower according to the invention, wherein a transmission range indicated by dashed lines in dashed lines is indicated,
- Fig. 5 shows a further embodiment of the double fan according to the invention, are provided in the belt or rubber elements and
- Fig. 6 shows another embodiment of the double fan according to the invention, are provided in the toothed belt.
- a double blower 1 according to the invention for a heat exchanger 2 is shown in plan view.
- the heat exchanger 2 also called heat exchanger, is for example a conventional coolant radiator of a motor vehicle, as is usually provided for engine cooling.
- the double fan 1 has two fans 4, 5, wherein a driven first fan 4 is mounted in a known manner on an electric motor.
- the electric motor is indicated schematically in FIG. 1 by a square 6.
- the second fan 5 is mounted on a provided bearing block 7, which in Fig. 1 by a circle schematically is marked.
- Both fans 4, 5 are arranged so that they preferably in the middle (intersection of the diagonal) of the rectangular heat transfer 2 circumferentially touching at a single point. This point or the transmission range is indicated by a dashed line in FIG.
- the second fan 5 drives the second fan 5 directly via the first motor 4 driven by the electric motor 6, so that a positive drive is provided for the second fan 5.
- the second fan 5 runs with the first fan 4 with easy.
- about 3 A of the cost of an otherwise necessary second electric motor of the second fan 5 can be saved.
- % of the costs saved take on the additional expenses for the bearing block 7 and the design measures on both fans 4, 5. It is also advantageous that can be dispensed with a construction of the two fans 4, 5 in a common frame.
- the transmission element 10 is inventively provided on a lateral surface 1 1 of the first fan 4 and a lateral surface 12 of the second fan 5 or formed.
- Fig. 2 shows an enlarged view of the transmission area A with a view from the front closer, the Ü transmission element 10 in the form of a toothing, a first toothing 15 for the first fan 4 and a second toothing 16 for the second fan 5, is formed be.
- the transmission element 10 or the toothing 15, 16 By means of the transmission element 10 or the toothing 15, 16, a circumferential force and a normal force from the first fan 4 to the second fan 5 are transmitted as quietly as possible.
- a toothing 15, 16 is formed, after which there are two intermeshing gears of a transmission.
- the profile of the toothing 15, 16 may correspond to that of a toothed wheel, as shown in FIG. 3, a representation of the transmission range A with a viewing direction on the outer surface 11 of the fan 4, closer. But it is also possible, as shown in Fig. 2, a representation of the transfer area A with a view towards the outer surface 1 1 of the fan 4 closer to provide for the profile an alternating, offset in the circumferential direction toothing 15 with correspondingly offset teeth. In a complementary manner then the teeth 16 would be for the second fan 5 form.
- each fan 4, 5 surrounds its blades 7, 8 on the outside, which can therefore also be referred to as outer band or fan belt.
- the fans 4, 5 are preferably axial fans which, on account of the cylindrical jacket surface 11, 12, can also be referred to as fan shrouds.
- the outer band 1 1, 12 surrounding the blades 7, 8 is usually provided in order to be able to reduce air turbulence of the fan blades or blades 7, 8.
- the transmission element 10 may also be formed by a first peripheral element 21 surrounding the first lateral surface 11 and a second peripheral element 22 passing over the second lateral surface 12, which then permit torque transmission by means of frictional engagement and / or positive engagement.
- the first and second circumferential elements 21, 22 consist of belt or rubber elements 25, 26 which are stretched over the lateral surface 11, 12 of the fans 4, 5 and which are then pressed against one another applied by friction a torque transfer from the driven first fan 4 to the second fan 5 accomplish.
- first and second circumferential element 21, 22 in the form of a friction coating, not shown, which are applied to the lateral surfaces 1 1, 12 quasi as a second layer and then also by pressing both lateral surfaces 1 1, 12 a
- the fans 4, 5 together with the outer band are made of plastic.
- the friction coating for example, be easily sprayed onto the lateral surfaces 1 1, 12.
- FIG. 6 shows, for the first and the second circumferential element 21, 22 to provide toothed belts 27, 28, which are stretched over the lateral surface 11, 12 of the fans 4, 5 and externally with their Tooth profile intermesh to allow torque transfer by positive engagement.
- the toothed belt instead of the toothed belt to apply the corresponding profile itself directly on the lateral surfaces 1 1, 12.
- 3 and 4 exemplified profile coatings can be provided as a toothing 15, 16, which are applied to the lateral surface 1 1, 12 and allow a positive torque transmission.
- the profile coatings can be sprayed onto the lateral surfaces 1 1, 12, which then, for example, structures according to FIGS. 3 and 4 have.
