Definitions
- the field of the present invention is that of heat sinks and more particularly heat sinks for rotating electrical machines, such as generators or motors. More particularly, these electrical machines are intended to be installed on vehicles, especially automobiles.
- Rotating electrical machines such as generators or motors comprise a stator and a rotor. Coils forming coils are mounted on the stator and, for example, permanent magnets are attached to the rotor.
- the rotor is rotatable by means of a shaft. When the electric machine is a generator, the rotational movement of the rotor facing the stator coils can generate electrical energy and when the electric machine is a motor, rotating the rotor through the coils generates mechanical energy.
- a first part configured to be in contact with a coil head of the rotating electrical machine
- the second part being thermally coupled to the first part, characterized in that the first part is configured to be housed inside a hollow delimited by the coil head.
- thermally coupled is meant that an exchange of calories is possible between the first and the second part.
- first and the second part are mechanically linked and the second part participates in the cooling of the first part.
- the heat sink object of the invention is monobloc. It is understood here that the first part, the second part, and possibly a base common to these two parts, are unitary, that is to say made simultaneously and from the same material, for example a thermally conductive material such as than an aluminum-based alloy. Such an organization eliminates any thermal interface on the path of the heat flows within the dissipator according to the invention.
- Such a heat sink housed inside a hollow formed by the coil head ensures a maximum heat exchange surface, which provides improved cooling and is particularly suitable for a reduced electric machine size .
- the hollow is delimited on one side by the coil head and on the other by the stator plate package.
- a rotating electrical machine is understood as distinct from a linear electric machine. It can also be expected that the first part is configured to be in contact with several coil heads. Indeed, this one could present a form of U for example.
- the first part and the second part extend from a common base, each of the parts extending from an opposite face of the common base.
- first part extends from a lower face of the common base
- second part extends from an upper face of the common base.
- the common base is configured to contact an upper surface of the coil head.
- the upper surface of the coil head is defined as the surface of the coil head furthest from the axis of rotation of the electric machine.
- the second part comprises at least one blade ensuring the heat exchange with the external environment. The presence of blade increases the heat exchange surface of the second part with the external environment, cooling is thus found improved. At least one blade is configured to extend radially outwardly of the rotating machine.
- the second part comprises a plurality of blades extending along the longitudinal axis.
- the first part has at least one rounded face configured to be in contact with the coil head.
- this heat sink protects the son forming the coils with a rounded face, while providing a maximum heat exchange surface with the coil head to cool the coil heads.
- a rounded face makes it possible not to break the wires during the winding step.
- the common base has a rounded face extending from a plane vertical face. Such a configuration is suitable for a dental winding stator.
- the common base may have a polygonal face, for example rectangular or square. Such an alternative is particularly suitable for a distributed winding stator.
- each blade extends in a plane perpendicular to a plane in which extends the flat vertical face of the common base.
- the first part of the heat sink is hollow. Thus, this reduces the total mass as well as the parts subjected to heating due to the variable magnetic fields of the electric machine.
- the first part of the heat sink has a U-shaped section.
- the first part is hollow and open along its length.
- the section of the first part is taken in a transverse sectional plane to the first part, the cutting plane being contained in a reference system defined by the longitudinal and transverse axes of the heat sink.
- the invention also relates to a heat dissipating member for a rotating electrical machine, characterized in that it comprises several heat sinks as defined above.
- Such a heat dissipating member allows, during its installation on a rotating electrical machine, to ensure the cooling of several coil heads on one side of the electric machine.
- This dissipation member is made in one piece.
- the heat sinks are interconnected by their common bases. Thus the first and second parts of the heat sinks remain free, which ensures heat exchange.
- the connection between the heat sinks is understood as a mechanical connection.
- the heat sinks are molded or welded together.
- the dissipation member is organized in a ring.
- crown it is understood that the heat dissipating member has a multitude of heat sinks substantially forming a circle or ring.
- the circular shape has the advantage of integrating well into a rotating electrical machine at the longitudinal end thereof.
- Such crown allows, when installed on a rotating electrical machine, to ensure the cooling of all the coil heads on one side of the electric machine. This crown can be made in one piece.
- the common bases connected to each other delimit a central volume of the ring and have a polygonal section with N sides, where N is equal to the number of heat sinks included in the heat dissipating member.
- N is equal to the number of heat sinks included in the heat dissipating member.
- the central volume of the crown is interrupted by the first parts of the heat sinks moving towards the center of the crown.
- the polygonal section is made according to a plane contained in a reference defined by the vertical and transverse axes of the crown as they are defined by the trihedron. Such geometry makes it possible to ensure that the bases of the heat sinks rest on the outer surfaces of the coil heads.
- each blade extends radially with respect to a center of the crown. This orientation of the blades makes it possible on the one hand to optimize the number present on the ring and on the other hand not to interrupt a circulation of a cooling fluid that can pass along the electric machine.
- the invention also relates to a rotating electrical machine comprising:
- stator on which the plurality of coils is wound, the plurality of coils having coil heads, each coil head protruding longitudinally from the stator and having a recess,

- FIG. 1 shows a heat sink 10, here individually, for a rotating electrical machine comprising a first part 1 configured to be in contact with a coil head of the rotating electrical machine.
- the heat sink 10 is said to be individual because it is intended here to be in contact with only one coil head.
- the heat sink 10 also comprises a second part 2, distinct from the first part 1, ensuring a heat exchange with the external environment.
- the first and the second part 1, 2 are thermally coupled, it means that there is a heat exchange between the first and the second part 1, 2.
- the second part 2 thus allows to cool the first part 1.
- the first part 1 and the second part 2 extend from a common base 3. More specifically, each of the parts 1, 2 extends from an opposite side of the common base 3. Thus the first part 1 extends from a lower face 31 of the common base 3, while the second portion 2 extends from an upper face 32 of the common base 3. The lower face 31 and the upper face 32 are defined along the vertical axis V. First part 1, second part 2 and common base 3 forms the same unitary part.
- the first part 1 is configured to be housed inside a hollow delimited by the coil head.
- the first part 1 may be in the form of a finger 11 having a cross section comprising a circular arc.
- the finger 11 comprises a rounded face 12 and a flat vertical face 13.
- the rounded face 12 is the face intended to come into contact with the coil head, such a rounded face 12 allows to offer both a surface of maximum heat exchange and protection of the son forming the coils during the winding step.
- the finger 11 here has a semicircular cross section, the cross section being made in a plane defined by the longitudinal axis L and the transverse axis T.
- the first part 1 can be hollow in order to reduce the mass of the heat sink 10 as well as the masses subjected to heating due to the variable magnetic fields of the electric machine.
- the first portion 1 may have a U-shaped section being open on its flat vertical face 13, as will be described later.
- the common base 3, more particularly its lower face 31, is configured to contact an upper surface of the coil head.

- the flat vertical face 34 extends in a plane B defined by the vertical axis V and the transverse axis T.
- the semicircles forming the first part 1 and the common base 3 of the heat sink 10 extend from the same center and have different radii. Indeed, the semicircle defining the finger 11 has a radius less than the semicircle defining the common base 3. Furthermore, the second part 2, ensuring the heat exchange with the external environment, here comprises a plurality of blades 25. These blades 25 can increase the heat exchange surface of the second part 2 with the external environment cooling is thus improved.
- Each blade 25 extends in a plane LM defined by the vertical axis V and the longitudinal axis L.
- the plane LM is preferably perpendicular to the plane B in which extends the flat vertical face 34 of the common base 3. Without limitation, the plane LM could equally be parallel or oblique to the plane B.
- the blades 25 are opposite to the first part 1, relative to the common base 3. View in a reference frame of the rotating machine for receiving the heat sink object of the invention, the blades 25 extend radially outwardly of the rotating machine.
- the first part 1 extends radially and inwardly of the rotating machine, that is to say towards its axis of rotation.
- the blades 25 have variable lengths along the longitudinal axis L of the heat sink 10. More precisely, the blades 25 follow the arc of the common base 3. Otherwise said blades 25 extend from the rounded face 33. In addition, the blades 25 extend, in length, partially on the common base 3. In fact, starting from the rounded face 33, the blades 25 are interrupted before reaching the vertical face 34 so as to release a space for cooling fins which emerge peripherally from a stator of the rotating machine (see in particular FIG. 4). Alternatively, the blades 25 may extend longitudinally over the entire common base 3, from the rounded face 33 to the vertical face 34. It should also be noted that the blades here have a constant height along the vertical axis V of the Heat sink 10. Of course, the blades 25 could have different heights with each other.
- the heat sink 10 may be made of a thermo-conductive material heating slightly under the effect of a variable magnetic field. Such a material provides improved heat transfer.
- This material may for example be aluminum, a non-magnetic steel, titanium or an alloy based on these metals or a synthetic material loaded with heat-conducting fibers.

- Each individual heat sink 10 is connected to neighboring heat sinks 10 by its common base 3.
- the first part 1 and the second part 2 of each heat sink 10 forming part of the dissipating member remain free, which ensures the thermal cooling of the coil heads.

- the vertical polygonal section has twelve sides.
- the blades 25 extend, here, radially with respect to the center C of the ring 50 and follow an axial direction of the ring 50, that is to say along the longitudinal axis L. This orientation of the blades 50 allows on the one hand to optimize the number present on the ring 50 and on the other hand not to interrupt a circulation of a cooling fluid that can pass along the electric machine.
