Definitions

  • the invention relates to an axial or radial fan with a bypass channel in the electronics housing for cooling the motor electronics.
  • the object of the invention is therefore to provide an axial or centrifugal fan that has improved cooling of the motor electronics with the least possible and cost-effective use of materials.
  • an axial or centrifugal fan is proposed with a motor and a fan wheel that can be driven by the motor and rotated about an axis of rotation.
  • Motor electronics are arranged axially adjacent to the motor and accommodated in an electronics housing.
  • At least one continuous bypass channel is formed in the electronics housing, which extends from an inflow opening on an axial end face of the electronics housing opposite the fan wheel in the axial direction to the motor electronics and then runs radially outwards along the motor electronics to a radial outflow opening on the electronics housing.
  • the outflow opening is formed on the pressure side or adjacent to the pressure side, so that a negative pressure is generated in a section of the bypass channel adjacent to the outflow opening.
  • the exhaust air flow generated by the fan wheel is used twice.
  • a negative pressure is generated by the Bernoulli effect by flowing past the outflow opening in the bypass duct
  • each axial fan an axial return flow, which runs from the pressure side back in the direction of the suction side and thus flows towards the inflow opening on the axial end face of the electronics housing opposite the fan wheel.
  • This generates a flow of cooling air, which is formed by an axial inflow into the inflow opening, a flow through the bypass channel and the outflow from the outflow opening.
  • the cooling air flow is then discharged into the environment by the blow-out air flow of the fan wheel. If the exhaust air flow does not flow directly past the outflow opening, such as in the case of a radial axial fan, the exhaust air flow nevertheless generates a pressure difference that extends into the bypass duct and generates a cooling air flow.
  • the motor electronics are arranged axially directly adjacent to the motor and an outlet of the fan wheel on the pressure side runs in a radial plane perpendicular to the axis of rotation.
  • the outlet of the fan wheel is defined as the axial edge plane of the fan wheel facing the electronics housing.
  • an embodiment of the axial or radial fan provides that the outflow opening on the electronics housing is spaced axially relative to the fan wheel.
  • the outflow opening preferably borders on the axial edge plane of the fan wheel facing the electronics housing.
  • the bypass duct has a nozzle-shaped course from the inflow opening to the outflow opening in one embodiment variant.
  • the channel walls delimiting the bypass channel are aligned in such a way that the cross-sectional area through which flow can take place towards the outlet opening is reduced at least locally in order to use the principle of the Venturi nozzle.
  • the axial or radial fan is characterized in that the bypass channel runs in the circumferential direction in a locally limited manner in the electronics housing. Cooling only takes place for particularly hot components in the engine electronics. Additional components or fastening means that are independent of the bypass channel can be provided in the remaining circumferential section of the electronics housing.
  • a development of the axial or radial fan provides that an air guiding element is arranged in the electronics housing, which forms a channel wall of the bypass channel that extends radially outwards in the direction of the outflow opening.
  • the air guide element can be used to deflect the cooling air flow, which initially flows in in the axial direction, in the radial direction and to guide it to the outflow opening.
  • the air guiding element preferably protrudes a little radially outwards relative to the lateral surface of the electronics housing and forms the bypass channel on one side axially further than the electronics housing itself.
  • a ring element which protrudes radially from a lateral surface of the electronics housing and delimits an axial side of the outflow opening is also arranged on the outflow opening.
  • the axial flow generated by the fan impinges on the ring element and increases the negative pressure at the outflow opening and consequently accelerates the flow speed of the cooling air flow through the bypass channel. This in turn increases the heat dissipation.
  • the ring element has a peripheral axial projection at its radially outer end, which extends in the direction of the fan wheel.
  • an advantageous embodiment provides that the ring element and the air guiding element overlap one another and the ring element forms a radial continuation of the air guiding element.
  • the bypass duct is thus led out of the electronics housing axially on one side and is in direct operative connection with the exhaust air flow generated by the fan wheel.
  • the axial or centrifugal fan is characterized in a further development in that several cooling ribs are formed on the electronics housing in the bypass channel, which extend radially to the outflow opening and on a channel wall of the bypass channel that adjoins the motor electronics. Cooling fins are a well-known measure for heat dissipation. In the present case, it is particularly favorable that the cooling fins run along and in the bypass channel and the cooling air flow flows around them.
  • the air guide element that delimits the bypass channel and guides the flow of cooling air radially outward preferably rests on an axial end face of the cooling ribs. This creates a plurality of bypass channels adjacent to one another in the circumferential direction.
  • the axial or radial fan in one embodiment also includes a cooling ring surrounding the outflow opening with blades arranged or formed on it, which is connected to the motor or the fan wheel and rotates radially on the outside around the outflow opening during operation.
  • the blades create an additional suction of the cooling air flow from the outflow opening of the bypass channel.
  • the cooling ring is preferably arranged axially adjacent and spaced apart from the ring element by a flow gap.
  • the electronics housing is made of plastic.
  • the material thickness is deliberately kept low and can be produced by injection molding. Contrary to the frequent practice of material accumulation, small wall thicknesses are provided by means of plastic, which favors the promotion of heat via the cooling air flow.
  • plastic is cheaper as a material than aluminum, for example.
  • FIG. 1 and 2 a first variant of an axial fan 1 is shown with the motor 2 designed as an external rotor motor and the fan wheel 3 attached thereto, which encloses the motor 2 radially on the outside with its hub.
  • a plurality of fan blades 23 arranged in a blade ring extends from the hub along the axis of rotation Viewed axially adjacent to the motor 2 is the motor electronics 4 , which is accommodated by the electronics housing 8 .
  • the continuous bypass channel 9 is formed in the electronics housing 8, which initially extends in the axial direction from the inflow opening 7 on the axial end face of the electronics housing 8 to the motor electronics 4 and then radially outwards along it of the motor electronics 4 (printed circuit board) to the radial outflow opening 6 of the electronics housing 8 runs.
  • the inflow opening 7 can be designed as a hole, holes, slot or recess in the electronics housing 8 .
  • the electronics housing 8 covers the motor electronics 4 and encapsulates them from the environment.
  • the bypass channel 9 extends in the circumferential direction only over the predetermined part of the electronics housing 8, so that it can be closed in the remaining section.
  • the outflow opening 6 is on the pressure side D opposite the outlet 10 of the fan wheel 3, i.e. the outlet edge plane of the fan wheel 3, axially directly adjacent or axially spaced, so that the blow-out air flow sucked in from the suction side S and exiting on the pressure side D flows past the outflow opening 6 and in the bypass channel 9 generates a negative pressure.
  • the plate-shaped air guide element 13 extending radially outward perpendicularly to the axis of rotation is arranged in the electronics housing 8 and forms the upper part of the duct wall of the bypass duct 9 in its radially outwardly extending section. All other channel walls are provided by the electronics housing 8 itself.
  • a plurality of cooling ribs 19 formed by the electronics housing 8 also run within the bypass channel 9, with figure 1 due to the sectional view, only one cooling fin 19 can be seen.
  • the cooling fins 19 extend in the radial direction and each form their own flow channels within the bypass channel 9.
  • the air guiding element 13 rests on the cooling fins 19 and closes the flow channels.
  • the cooling fins 19 limits directly to the engine electronics 4.
  • the ring element 11 protruding radially from the outer lateral surface of the electronics housing 8 is arranged at the outflow opening 6, with the air guiding element 13 and the ring element 11 overlapping in sections.
  • the ring element 11 is formed in one piece by the electronics housing 8 and delimits the axial side of the outflow opening 6 on the axial side of the bypass channel 9 opposite the fan wheel 3.
  • the ring element 11 protrudes in the radial direction beyond the hub of the fan wheel 3, so that the radially outer free end lies in the exhaust flow.
  • the ring element 11 has a peripheral axial projection 12 which extends in the axial direction towards the fan wheel 3 .
  • figure 2 is off when axial fan 1 is in operation figure 1 resulting flow of cooling air through the bypass channel 9 outlined by arrows. Reference numerals are removed in this view for clarity.
  • the flow of cooling air is generated by the pressure difference ⁇ p at the outflow opening and the return flow axially downstream of the axial fan 1 .
  • FIG. 3 and 4 an alternative embodiment variant of the radial fan 1 is shown, in which an axially sucking and radially blowing fan wheel 3 is used. All other characteristics agree with those figure 1 coincide, so that these are not repeated, but are expressly disclosed.
  • the pressure side is radially on the outside, but also adjacent to the area of the base plate of the fan wheel 3 facing the electronics housing 8, as in FIG figure 4 also shown there is a pressure difference ⁇ p at the outflow opening 6 for generating the cooling air flow.
  • the arrows in figure 4 show the exhaust flow and the cooling air flow through the bypass channel 9 according to the embodiment in Figures 1 and 2.
  • FIG 5 is another alternative embodiment of the axial fan 1 based on the solution according to FIG figure 1 shown.
  • the features are consistent with the solution figure 1 match, but the cooling fins 19 have been omitted in this embodiment.
  • the cooling ring 14 enclosing the outflow opening 6 is provided.
  • the cooling ring 14 is connected to the motor 2 or the fan wheel 3 and rotates radially on the outside around the outflow opening 6 during operation.
  • the cooling ring 14 has cooling blades 18 distributed over the circumference and pointing towards the outflow opening 6 and generates air convection, which causes the cooling air flow through the bypass duct 9 encourages.
  • a flow gap is provided between the ring element 11 and the cooling ring 14 so that the effect of the pressure difference generated from radially outside based on the blow-out flow and the air convection through the cooling ring 14 complement each other.
  • the flow of cooling air is the same as in figure 2 shown by the arrows.
  • the cooling ring 14 is only in the version according to figure 5 used, but can also be integrated into the designs according to all other figures.
  • the electronics housing 8 is formed in one piece from plastic in all versions and has thin walls at least in the sections defining the bypass duct walls, so that the heat generated by the engine electronics 4 can be easily dissipated via the cooling air flow flowing through the bypass duct 9 .
  • the flow cross-sectional area may decrease from the inflow opening to the outflow opening in order to provide a nozzle function.
  • the flow cross-sectional area can be determined via the channel walls, the guide element and the cooling fins, if provided.
