Definitions
- the invention relates to a heatsink ring for attachment to an outer casing wall of a heat-dissipating electric motor.
- the invention also relates to an electric motor with such a heat sink ring and a Antriebsan arrangement comprising an electric motor with such a heat sink ring.
- DE 102004007 395 B4 describes a motor generator with a cover-integrated base plate, which has a large number of through-holes as cooling air passages, which are arranged parallel to the radial direction.
- the base plate is screwed to the front of a second housing component of the motor generator using screws.
- the object of the invention is to provide a heatsink ring, in particular an electric motor with such a heatsink ring and in particular a drive arrangement with such a heatsink ring, through which heatsink ring the heat dissipation from the electric motor is improved.
- the object is achieved by a heatsink ring for fastening to an outer casing wall of a heat-dissipating electric motor, having:
- Circumferential cooling fins limit a flow channel for radially and / or tangentially flowing air
- cooling ribs laterally delimited flow channel from the outside, such that an air flow that has entered the flow channel in a first region of a side of the heat sink ring facing the incoming air is deflected into a second region of a side of the heat sink ring facing away from the incoming air.
- the heat sink ring can be designed either as a closed ring or as an open, ie slotted, ring. However, the ring must at least extend more than 180 20 degrees around the circumference of the outer casing wall of the motor, so that after the cooling body ring has been pushed axially onto the outer casing wall of the heat-emitting electric motor, the cooling body ring is radially fixed in a form-fitting manner.
- a non-positive or frictional connection may be sufficient, for example by means of a resilient design of the heatsink ring.
- a spring-elastic design of the heat sink ring can be achieved, for example, by designing the heat sink ring as a slotted ring. Due to the radial form-fitting fixation and the axial push-on The heatsink ring can easily be retrofitted to a motor without the motor as such having to be structurally modified, for example by redesigning the motor housing. By attaching an additional heatsink ring to an outer jacket wall of a heat-dissipating electric motor, such an existing motor can be upgraded with a heatsink ring in order to increase its heat dissipation capability.
- the cooling body ring is particularly suitable for a cooling air flow to flow around it, which is fed radially to the motor, so that the motor flows perpendicularly to its axial extension and in particular flows around it.
- the axial extent of the motor results from the axial alignment of the motor shaft of the motor.
- the peripheral inner wall of the heat sink ring forms an inward-facing lateral surface of the heat sink ring. With the inner wall running around, the cooling body ring is at least largely or completely flush with the outer casing wall of the electric motor when the cooling body ring is plugged onto the motor.
- Heat is transferred via the contact surface of the circumferential inner wall of the heat sink ring with the outer jacket wall of the electric motor in order to dissipate the heat generated in the motor to the heat sink ring Heatsink ring and the outer jacket wall of the electric motor be interposed a thermal paste.
- the circumferential inner wall of the heat sink ring does not necessarily have to be completely 360 degrees, rather, as already mentioned, the ring can only extend over an angle between 180 degrees and 360 degrees, so that the inner wall of the heat sink ring only over a part of 360 degrees.
- the peripheral inner wall of the cooling body perring can optionally also be interrupted, for example when the cooling body ring is designed as a slotted ring or the cooling body ring has indentations, window cutouts or recesses on the inside despite being designed as a closed ring.
- the cross-sectional contour of the heatsink ring which is adapted to the shape of the outer casing wall of the electric motor, is to be understood in such a way that the largest possible contact surface is achieved between the heatsink ring and the motor, i.e. between the circumferential inner wall of the heatsink ring and the outer casing wall of the electric motor.
- the cross-sectional contour of the heatsink ring does not necessarily have to be identical to the cross-sectional contour of the motor. Rather, despite a largely adapted cross-sectional contour, i.e. offering the largest possible contact surface between the heatsink ring and the motor, the cross-sectional contour of the heatsink ring can deviate slightly from the cross-sectional contour of the motor.
- the cross-sectional contour of the heatsink ring can, if appropriate, be designed identically to the cross-sectional contour of the motor.
- the heat sink ring is pushed onto the outer casing wall of the electric motor in the axial direction in a direction parallel to the axis of rotation of the motor shaft of the motor.
- the circumferential cooling ribs extending radially outwards can be continuous over the entire circumference of the cooling body ring, or in the case of a design of the cooling body ring of less than 360 degrees over a corresponding partial circumference.
- the radially outward path can stretching circumferential cooling ribs over the entire circumference of the cooling body ring, or if the cooling body is designed to be interrupted by rings of less than 360 degrees over a corresponding partial circumference, ie a circumferential cooling rib arranged in an axial height position can be formed by two or more partial circumferential cooling ribs.
- the cooling fins arranged around the circumference of the heatsink ring are to be understood in this context of the disclosure in this broad sense.
- the circumferential cooling ribs or the two or more partial circumferential cooling ribs extend parallel to one another at a distance from one another, so that two immediately adjacent circumferential cooling ribs or partial circumferential cooling ribs delimit a flow channel for radially and/or tangentially flowing air.
- the flow channels delimited by them can also be referred to as partial flow channels.
- the baffle sections cover at least one flow channel laterally delimited by the peripheral cooling ribs in sections from the outside.
- the guide wall sections can divert an air flow that has entered the flow channel in a first area of a side of the heatsink ring facing the inflowing air into a second area of a side of the heatsink ring facing away from the inflowing air.
- the cooling body ring serves in particular to be used for a flow of cooling air, which is supplied radially to the motor, so that the motor is flown against and in particular flows around perpendicularly to its axial extension.
- another function is to promote or ensure that the air flow around the heatsink ring is as homogeneous as possible and thus around the engine. This affects both a complete flow around the engine, including on the side facing away from the air, and an at least reasonably uniform flow through the cooling fin channels, especially the flow channels that are in the slipstream of the engine, i.e. the side of the engine facing away from the inflowing cooling air.
- the heatsink ring has the additional guide wall sections, which close the radial fins, ie the cooling fins in order, from the outside and thus form closed channels.
- these guide wall sections can be open on the engine side or inwards and guide the air directly along the engine jacket surface.
- the guide wall sections can be geometrically matched to the surrounding cooling fins and designed in such a way that they open out into individual cooling fin channels in a targeted manner. By varying the number of openings and their height, the air flow and air distribution around the engine can be specifically influenced.
- the inlet of the guide wall sections can be located in particular on both sides next to the engine in the area of the center plane of the engine. This is where the air comes together, for example from many cooling rib channels in front of the motor, which cannot escape over the motor due to the circumferential cooling ribs of the heat sink ring. Additional, possibly funnel-shaped guide elements at the entrance are optionally possible.
- the bulkhead cooling ribs In addition to a tangential or circumferential air flow, additional Additional bulkhead cooling ribs, ie top ribs of the heatsink ring on the rear of the engine, ie on the front for air ducting, the bulkhead cooling ribs have the particular function of directing the air flow, which runs over the front of the engine, into central cooling rib channels that do not have bulkhead cooling ribs tend to be poorly flowed through.
- further guide elements can also direct the air downwards again after the engine in the middle area.
- the heat sink ring can be specially matched to the heat sink with the niche, as will be described in more detail below.
- the baffle sections can be pulled much further around the engine.
- the barrel outlets can, for example, be in the area of the motor side facing away from the air - the inlets of the guide channels are again on both sides next to the motor - in the area of the motor center plane.
- An arrangement of cooling fins that run horizontally and radially can enable a trouble-free tangential flow around the engine body, with the heat-dissipating surface surface can be quintupled, for example, in the area of the motor side.
- the surface of the top or rear of the motor is also provided with cooling fins, which means that the heat-dissipating surface can be doubled again, for example.
- a close connection - preferably a clamp connection of the lateral surfaces - creates a large-area contact between the heat sink ring and the motor.
- the contact can be made both on the side surface and also on the back of the motor.
- the ring When the ring is under tension, it can have elastic or more elastic areas that allow deformation and snuggling.
- the heat transfer can be improved by using a thermal compound between the motor and the heatsink ring.
- the heatsink ring can thus be tightly secured around the motor, preferably by clamping.
- the heat sink ring is always motor-specific and adapted to the motor geometry.
- the heat sink ring can be made of a material with good thermal conductivity, preferably a metal, preferably aluminum, and is preferably produced in one piece as a cast construction or metal 3D print.
- the heat sink ring can also be produced in two or more parts in a differential construction. The latter enables a kind of modular system with scalable basic elements, such as a retaining ring, several radial cooling elements, which have the peripheral cooling ribs, and air guiding elements, which have sections of the baffle. This enables a simple and inexpensive modification or adaptation of the heatsink ring to different geometries of the motor.
- the heatsink ring according to the invention can be used not only for cooling engines but also for cooling other bodies, such as containers with hot fluids, or the like.
- the at least one baffle section may be releasably attached to one or more circumferential fins for reattachment such that an existing baffle section may be removed from its current location on the circumferential fins and reattached to a different location on the circumferential fins.
- each guide wall section can have clamping sections which are designed for clamping the respective guide wall section to one or two immediately adjacent cooling fins in order.
- a respective baffle section can also be clamped between two immediately adjacent circumferential cooling fins.
- the at least one baffle section can be formed in one piece on the heat sink ring, manufactured by means of an adjustable mold insert, such that by adjusting and/or remounting the mold
- Use heat sink rings can be manufactured with differently positioned guide wall sections.
- the cooling body can be perring produced, for example, by a casting process.
- those molding tool inserts are used within a mold for the production of cast heat sink rings, which form the guide wall sections, are arranged on the mold adjustable or remountable.
- heat sink rings can be produced which have differently positioned guide wall sections or have a different number of guide wall sections or have differently shaped guide wall sections.
- the flow channels delimited by the circumferential cooling ribs can be open at least in sections towards the inner wall, so that the flow channels are not delimited on the inner circumference by the inner wall of the cooling body ring, but rather in a fastened state of the cooling body ring on a motor, the flow channels at least in sections of the outer casing wall of the motor.
- the cooling air flow can be guided directly along the outer casing wall of the motor.
- the flow cross section in the individual flow channels can be increased with the boundary walls omitted.
- material and consequently weight can be saved on the heat sink ring.
- the heat sink ring can have at least one end wall section on which a plurality of end wall cooling ribs are arranged.
- the end wall cooling ribs can be designed to direct the air flow that has entered the first area of the side of the heat sink ring facing the inflowing air into the second area of the side of the heat sink ring facing away from the inflowing air, with the end wall cooling ribs running obliquely or in an arc shape over the width of the first Area entered air flow concentrate in a central portion of the second area.
- the end wall cooling ribs can preferably or completely cross, i.e. in particular in an orientation analogous to a secant of a circle, over the end face of the engine.
- a plurality of end wall cooling ribs can extend over the end face, aligned at least essentially parallel to one another.
- the end wall cooling ribs can have asymmetrical courses in a second surface half of the end wall section compared to the courses of end wall cooling ribs in a first surface half of the end wall section. This means that the end wall cooling ribs do not have to be mirror-symmetrical or identical in design with respect to a center line, but can be arranged to run in different ways. Relative to a vertical center line, the end wall cooling ribs can run differently in a left half than the end wall cooling ribs in a right half of the end wall section.
- the end wall section does not necessarily have to be of closed surface design, but can, for example, NEN window section or even two or more window sections have. If, for example, a window cutout is formed in a central area of the bulkhead section, for example to create space for a rear bulge or a rear projection on the engine, this bulge or projection can protrude through the window cutout when the heat sink ring is on the engine is stretched.
- the front wall cooling ribs can run in such a way that a cooling air flow directed onto the bulge or the protrusion is guided around the bulge or the protrusion by means of the front wall cooling ribs and optionally brought together again at least partially or completely behind the bulge or the projection.
- the heat sink ring can be designed to be spring-elastic, such that the heat sink ring can be clamped onto the motor with its peripheral inner wall resting against an outer jacket wall of a heat-emitting electric motor.
- the heatsink ring can have screw flange sections, to which clamping screws can be attached in order to be able to clamp a slotted cooling body ring by tightening the clamping screws on the motor.
- Such clamping screws can be expedient, particularly if the heat sink ring as such cannot exert a sufficiently high spring clamping force on the motor, or the heat sink ring is essentially not designed to be resilient at all.
- the object is also achieved by an electric motor having a rotor with a motor shaft, a stator, in in which the rotor is rotatably arranged, and a motor housing with an outer casing wall, with a heat sink ring according to at least one of the described embodiments being arranged on the outer casing wall of the electric motor.
- the outer casing wall can be part of the motor housing.
- the stator can be fastened in the motor housing.
- a drive arrangement having a heat-dissipating electric motor, a heat sink ring arranged on the electric motor according to at least one of the described embodiments, and a cooling device which comprises at least one heat sink and at least one fan that acts on the heat sink with air.
- the heat sink has a niche into which the heat sink ring protrudes when the electric motor is installed on the drive arrangement, so that the air introduced by the fan into the ducts of the heat sink enters the heat sink ring on one side and on at least one side the opposite side of the heat sink ring exits again to re-enter the heat sink.
- the cooling body ring serves in particular to be used for a flow of cooling air, which is supplied radially to the motor, so that the motor is flown against and in particular flows around perpendicularly to its axial extension.
- the cooling air flow can be brought into an inflow by means of the cooling element of the cooling device, which is fed radially to the motor, so that the motor is flowed perpendicularly to its axial extension and in particular flows around it.
- the cooling device comprises at least one fan, so that forced convection is achieved on the heat sink and on the heat sink ring.
- the heatsink ring has the additional guide wall sections, which close the radial fins, ie the cooling fins in order, from the outside and thus form closed channels.
- the peripheral cooling ribs can have recesses on their peripheral outer edges, which are aligned in the axial direction with one another in such a way that one or more channel-like undercuts are formed, into which lamellae of the cooling body protrude in the arrangement of the cooling body ring inserted into the niche of the cooling body.
- two adjacent end wall cooling fins can each delimit a flow channel of the heat sink ring, with the flow channels of the heat sink ring being aligned with flow channels of the heat sink in the arrangement of the heat sink ring inserted into the niche of the heat sink and/or opening into them.
- the end wall cooling ribs can in particular be aligned with the flow channels of the heat sink and/or open into them in such a way that a flow of cooling air coming from the heat sink is diverted within the niche, i.e. in the end wall section of the heat sink perring, and after flowing through the niche at the other end of the heatsink ring at least partially or completely in a middle area, ie central Be is richly merged where the cooling air flow after leaving the heatsink ring re-enters the heatsink.
