- air e.g. Cooling air
- the fan device consists of two separate modules. If the regulator device is arranged in the radial air flow of the fan device on a module carrier of the fan device, then the regulator device must be designed so that on the one hand the heat sink is sufficiently in the air stream to be cooled and on the other hand the regulator device can be accommodated in the limited space , As a rule, this leads to complex and expensive solutions, in particular in connection with the special form of the fan device.
- a heat sink of the control device which also protrudes into the radial air flow of the fan device, causes a disturbance of the air flow. This in turn leads to a reduction of the blower output.
- an improved blower device 10 with an integrated regulator device 20 is now provided.
- FIG. 6 shows a blower device 10 according to an embodiment of the invention in a perspective view from the direction of the motor 16 of the blower device 10.

- a receptacle 32 is arranged in a housing section below the fan device.
- an air flow is sucked in by the fan device and then a part of the air flow along the regulator device 20 is led to the motor 16 in order, for example, to cool it as well.
- the blower device 10 is shown, without the connectable with her fan housing device. In this case, the blower device 10 is shown from the direction of the entrance of the fan device 12.
- the regulator device 20 is arranged in a receptacle 32 in the housing or housing section 30.
- the regulator device 20 is closed or disconnected in the axial direction toward the fan device 12. This is achieved by providing a dividing wall member 34 between the regulator means 20 and the fan means 12.
- the fan device 12 is designed to be open to the regulator device 20 in the radial direction.
- the partition element 34 has for this purpose e.g. at least one opening 36 in the radial or in the substantially radial direction. In this way it is achieved that a part of the air flow of the fan device 12 can flow to the regulator device 20 or to the heat sink device 24, without the air flow of the fan device 12 is affected by the regulator device 20.
- the control device 20 has, for example as the heat sink device 24, a surface with nubs 38, e.g. with aluminum studs which are coolable by means of the air flow of the fan device 12.

- a first air duct section 40 in which the fan device 12 is arranged
- a second Air duct section 42 above, in which the regulator device 20 is arranged.
- the receptacle 32 is open in this case, so that the receptacle 32 can be flooded with the regulator device 20, for example, by a tangentially outflowing air of the ventilating device 12.
- this provides a kind of underfloor ventilation to the regulator device 20 suitable to cool, but without obstructing the air flow of the fan device 12.
- the two air duct sections 40, 42 are connected to each other in the radial direction, so that a part of the air flow of the fan device 12 can flow to the regulator device 20 and then to the motor 16.
- the regulator device 20 is installed in this receptacle 32 so that its heat sink device 24 lies in the tangential or substantially tangential air flow. Furthermore, this receptacle 32 is connected via the second air duct section 42 with the interior of the motor housing, so that at the same time a part of the air flow of the fan device 12 can be tapped and the motor 16 can be supplied to cool this example.
- the air duct guide is, as shown in Fig. 9, executed twice substantially in a symmetrical arrangement.
- air is first sucked in via the fan device 12, as indicated by the arrow in FIG. 9.
- the air mass flow in the radial direction exits from the fan device 12.
- the fan device 12 is, as described above, separated from the regulator device 20 in the axial direction by the partition wall element 34, so that the air flows through the first and second channel sections 40, 42 can not negatively influence each other.
- the partition member 34 is formed in the example, as shown in Fig. 9, for example, with a conical base 44. However, it can also have a flat base or any other shape, provided that the air guide along the Reglereinrich- device 20 is given to the motor 16.
- the partition wall member 34 for example, in addition to a side wall portion 46 which forms part of the second air duct portion 42 and at least partially separates it from the blower housing means 14, the air from the fan device 12, for example, an air conditioner, etc. supplies.
- part of the air mass flow of the fan device 12 flows in the direction of the regulator device 20 and from there outwards in the direction of the motor 16 via the second air channel section 42.
- the other or larger part of the air mass flow of the fan device 12 flows through the first air channel section 40 radially outward and from there, for example in a connected air conditioning or blower system of a vehicle.
- FIG. 10 shows a further sectional view of the fan device 10 according to the invention, wherein the fan housing device connectable thereto is not shown.
- the regulator device 20 in the receptacle 32 has, for example, a connection plug 28 in addition to the heat sink device 24 and the electronics 26.
- the e.g. partially circumferential side wall element 46 and the conical base 44 of the partition wall element 34 shown.
- the course of the air mass flow from the fan device 12 to the regulator device 20 and the motor 26 is indicated by arrows along the air passage sections 40, 42, as well as in FIG. 9.
- the regulator heating and the engine cooling are integrated in a common structural solution and need not be realized separately from each other.
- this solution is completely integrated in the fan module or in the fan device.
- the invention has the advantage that no extra interfaces are required for tapping the cooling air for the engine and the regulator device with respect to a customer air conditioning or blower system.
- the installation interface to the customer is much easier and more robust.
- Another advantage of the blower device according to the invention is that the positioning of the underfloor ventilation at the periphery of the blower device can be set independently of a customer air conditioner or customer blower system.
- the design is largely independent of the customer's design. The number of customer-specific variants is reduced.
- the cooling capacity for the engine and the regulator device is significantly less dependent on the customer's design and can be largely optimized without the customer blower system. Due to the essentially symmetrical design, the design can be used equally for CW and CCW blowers. This also significantly reduces the number of items required. With the underfloor ventilation construction, there is also sufficient installation space for a standard control device. There is no need to use a specially adapted and complex heat sink device. Through the upper cover to the fan device by means of the partition wall element of the radial air flow remains shielded and is not disturbed. The underfloor ventilation also proves to be relatively robust in terms of different receiving cross section and different cross-sections of blower housing devices. About the design and arrangement of the individual cross-sections of the flow rate of the cooling air flow can be further optimized.
- the blower device can be delivered as a blower module, as shown in Fig. 7, which later with a customer blower housing means, e.g. an air conditioner, can be connected.
- the blower device can also be provided with its own blower housing device, as shown for example in FIG. 6, and connected via a corresponding interface to a customer-side air conditioning or blower installation.
- the blower housing device has, for example, a radially and / or axially expanded section at the end, as shown in FIG.
- the end section of the blower housing device can hereby additionally be used as an interface for connection to an air conditioning or blower installation of a vehicle, e.g. Motor vehicle, be formed.
