    The invention relates to a power generator, in particular for range expansion of an electric vehicle, with an internal combustion engine formed in particular by a rotary piston engine and at least one corrugated with the internal combustion engine preferably permanent magnet excited electric machine, wherein the engine and electric machine are formed as a unit and a common housing, and a common Have cooling system.
    The AT 505 950 Bl describes a power generator for range extension of an electric vehicle, with a rotary piston internal combustion engine and a generator which is arranged coaxially with the output shaft of the internal combustion engine. The internal combustion engine and the generator are designed as a unit and have a common cooling system. The cooling water passes from a coolant pump into the water chambers of the generator and the internal combustion engine and is then fed to the air / water heat exchangers. The cooling channels of the generator and the internal combustion engine are directly connected to each other without separate lines.
    Furthermore, from DE 3 601 193 Al an aggregate of power generator and internal combustion engine is known, wherein the internal combustion engine and the generator have a common cooling water circuit, the coming of the generator, the generator heat laxative line is connected to the cooling water inlet of the engine.
    DE 4 020 416 A1 describes a generator with armature shaft cooling, the generator and a drive motor formed by an internal combustion engine having a common cooling system.
    In the power generator, the individual components have different heat inputs and different optimal operating temperatures.
    The object of the invention is to achieve a component-appropriate best possible heat dissipation for a power generator of the type mentioned.
    This is achieved according to the invention in that at least one electro-side cooling channel arrangement for cooling an electrical component, preferably the electric machine, is arranged in the cooling circuit of the cooling system upstream of at least one cooling channel arrangement of the internal combustion engine.
    In one embodiment of the invention it is provided that downstream of at least one Kühlkanaianordnung the internal combustion engine, an oil cooler is arranged in the cooling circuit of the cooling system. - 2 -
    In a particularly advantageous embodiment of the invention, it is provided that the electro-side cooling channel arrangement comprises a cooling channel arrangement part for cooling power electronics and a cooling channel arrangement part for cooling the electric machine, wherein preferably the cooling channel arrangement part for cooling the power electronics upstream of the cooling channel arrangement part for cooling the electric machine in the cooling circuit of the cooling system is arranged. This makes it possible to optimally temper the power electronics which require relatively low operating temperatures.
    Thus, all components which have a lower operating temperature than the internal combustion engine, cooled by the cool strand of the cooling system before the internal combustion engine. The power electronics can be integrated into a common housing for the internal combustion engine and the electric machine housing. All alternating current carrying parts can thus be arranged inside the housing. As a result, size can be saved and the electromagnetic compatibility can be increased.
    In a continuation of the invention may further be provided that a preferably map-controlled electric water pump is arranged in the cooling circuit of the cooling system outside the housing, wherein preferably the electric water pump - is arranged between the front and rear axle of the vehicle, and the housing in the front - or rear axle is positioned. But it is also possible to arrange the electric water pump in the engine compartment.
    With appropriate heat exchanger design, it is also possible to arrange the oil cooler upstream of the electric machine in the cooling circuit of the cooling system and / or the power electronics downstream of the internal combustion engine in the cooling circuit of the cooling system. However, care must be taken that the electrical components are not overheated.
    In an alternative embodiment of the invention may - provided with appropriate design of the cooling channel arrangements - that at least one electro-side cooling channel arrangement for cooling an electrical component, preferably the electric machine in the cooling circuit of the cooling system downstream of at least one cooling channel arrangement of the internal combustion engine is arranged. Furthermore, the cooling channel arrangement part for cooling the power electronics downstream of at least one cooling channel arrangement for cooling the internal combustion engine and / or the oil cooler upstream of at least one electrical side cooling channel arrangement, preferably for cooling the electric machine, are arranged in the cooling circuit in the cooling circuit of the cooling system. - 3 -
    As viewed around the axis of the eccentric shaft, rotary piston internal combustion engines have a cold angular segment region of the housing in the inlet region and a hot angular segment region of the housing in the combustion and exhaust region. These two angular segment areas have different heat input and thus a different cooling requirement.
    To take account of different heat inputs and component temperatures of the electric machine and the internal combustion engine may further be provided within the scope of the invention that the electro-side cooling channel arrangement and a first piston-side cooling arrangement of the first side housing part are arranged at least partially parallel in the cooling circuit of the cooling system, preferably one through the electric-side cooling channel arrangement guided and then the first piston-side cooling channel arrangement supplied second coolant flow is less than a substantially directly and at least predominantly bypass the electro-side cooling channel arrangement of the first piston-side cooling channel arrangement supplied first coolant flow. In this case, the first coolant flow after flowing through the cooling channels in the first piston-side cooling channel arrangement in the hot angular segment region of the internal combustion engine with the second coolant flow after flowing through the cooling channels in the first piston-side cooling channel arrangement and the central Kühikanalanordnung In the cold angular segment area in the region of a second piston-side cooling channel arrangement of the second housing part unite. Simulations have shown that a particularly favorable temperature of the individual components can be achieved if the volume flow of the first coolant flow about 70% to 90%, preferably 80% to 88%, preferably, supplied to the housing and / or from the second piston side cooling channel arrangement the second lateral housing part discharged, total coolant flow is. This allows for excessive cooling of the hot angle segment areas.
    The invention will be explained in more detail below with reference to FIGS.
    2 shows an electric vehicle with a power generator according to the invention, FIG. 3 shows a cooling circuit of a power generator according to the invention in a first embodiment, FIG. 4 shows a cooling circuit in a second embodiment, FIG 6 shows a cooling circuit in a fourth embodiment, FIG. 7 shows a cooling circuit in a fifth embodiment, and FIG. 8 shows a cooling circuit in a sixth embodiment. - 4 -
    Fig. 1 shows a power generation device 40 (range extender), in particular for range expansion of an electric vehicle 90, wherein in a housing 2, a rotary piston internal combustion engine 1 and an example, permanent magnet excited electric machine 14 is arranged. The housing 2 has a chamber 3, in which a rotary piston along a trochoid-shaped running surface 5 of the housing 2 is arranged circumferentially. The chamber 3 is formed by the trochoidal tread 5 and by lateral treads 6, 7. The housing 2 has a trochoidal tread 5 forming the central housing part 2a, a lateral first housing part 2b and a lateral second housing part 2c. Furthermore, the housing 2 between the central housing part 2a and the lateral Gehäusetei! 2b and / or the lateral housing part 2c have a side tread 6 and 7 respectively forming the first and second side plate 8, 9 on both sides. Furthermore, optionally between the cover part 2d and the electrical machine 14 receiving lateral first housing part 2b, a housing intermediate part 2e for receiving a power electronics 41 may be provided. If the power electronics 41 arranged outside of the housing 2 or in the Deckeleltei! 2d is integrated, the intermediate housing part 2e can be omitted. It is also possible the power electronics 41 in the first Gehäusetei! 2b to integrate.
    In the first and second housing part 2b, 2c, an eccentric shaft 10, which is arranged in an inner housing space 15 and is driven by the rotary piston 4, is rotatably supported by bearings 11, 12, which are designed, for example, as roller bearings. Shaft equal to the eccentric shaft 10 of the rotor 13 of the same housing 2 arranged in the electric machine 14 is formed.
    The first bearing 11 receiving lateral first Gehäusetei! 2b has a bell-shaped, cylindrical shell region 2b ', which spans a substantially cylindrical interior 15a, in which the rotor 13 and the stator 14a of the electric machine 14 are arranged. The cylindrical interior 15a is closed by a cover part 2d adjoining the housing part 2b.
    It is particularly advantageous if the entire power electronics 41 of the electric machine 14 are integrated in the cylindrical interior 15a or in the cover part 2d. As a result, all AC lines can be accommodated within the housing 2, whereby the electromagnetic compatibility can be substantially increased. Thus, only DC cables lead to the power generator 40 - the number of connections can thus be reduced to a minimum. - 5 -
    To avoid overheating of the electrical components and to dissipate the heat generated during combustion in the rotary piston internal combustion engine 1 is a cooling system 50 in the housing parts 2d (cover part), 2e (housing intermediate part), 2b (lateral first housing part), 2a (central housing part ) and 2c (lateral second Gehäuseteii) molded cooling channel arrangements 51, 52, 53, 54 are provided, wherein the individual components from the group of power electronics 41, electric machine 14 and a - possibly integrated into the oil pan of the power generator 40 - in Fig. 1 not further shown - oil cooler 35 are cooled sequentially. This makes it possible to comply with different component-specific temperature levels. In the embodiment shown in Fig. 1, the parts of the housing cover part 2d, first housing part 2b, first side plate 8, central housing part 2a, second side plate 9 and second Gehäuseteii 2c successively flowed through by coolant. The coolant inlet into the power generation unit 40 is arranged in the region of the cover part 2d, the intermediate housing part 2e or the first housing part 2b, the coolant outlet from the power generation unit 40 in the region of the second housing part 2c.
    An annular Kühikanalanordnung 51 to the electric machine 14 and the power electronics 41 may be partially formed by the first housing part 2b and the cover part 2d, possibly also by the intermediate housing part 2e.
    The electro-side Kühikanalanordnung 51 in the first housing part 2b (possibly also in the cover part 2d and Gehäusezwischenteii 2e) is connected to the piston side first coolant assembly 52 in the side first housing part 2b, the central coolant assembly 53 in the central housing part 2a and the piston side second coolant assembly 54 in the second side housing part 2c without external lines and fluidly connected directly within the housing 2.
    3 shows a variant in which the cooling channel arrangements 51, 52, 53, 54 of the electric machine 14, the rotary piston internal combustion engine 1 and the oil cooler 35 are flowed through in succession in the cooling circuit 50a of the cooling system 50 through which a cooling fluid flows. The emerging from the power generator hot coolant is returned to the power generator 40 via the vehicle radiator 36 and the advantageously map-controlled electric water pump 37.
    The cooling system 50 shown in FIG. 4 differs from FIG. 3 in that power electronics 41 are also cooled before or simultaneously with the electric machine 14. The electric-side cooling channel arrangement 51 has a cooling channel arrangement 511 for cooling the power electronics 41 and a cooling channel arrangement 512 for cooling the electrical machine 14. As indicated by dashed lines in Fig. 4, the Kühlkanalanordnun gungs- parts 511 for cooling the power electronics 41 and 512 for cooling the j electrical machine 512 are at least partially flowed through in parallel. j
    In a modification of the embodiment shown in Fig. 3, the oil cooler 35 in the cooling [50a circuit may also be arranged upstream of the electric machine 14, as shown in Fig. 5. It is also possible that the rotary piston engine 1 is positioned upstream of the electric machine 14 (FIG. 6). It is also conceivable to arrange the power electronics 41 in the cooling circuit 50a on the output side of the power unit 40 downstream of the electric machine 14 and the rotary piston internal combustion engine 1, as indicated in Fig. 7.
    As shown in FIG. 2, the power generation unit 40 can be arranged in the region of the rear axle 91 of the electric vehicle 90, wherein the cooling circuit 50a can be connected to the cooling circuit 50b of the vehicle cooling system 92 provided for cooling the electric drive motors. The cooling of the cooling medium of the common cooling system 50 takes place via the vehicle radiator 39. For weight and space reasons, the electric water pump 38 away from the power generator 40 - viewed in the direction of travel of the electric vehicle 90 - are arranged in front of the rear axle 91. This makes it possible to meet both the specific requirements of the electric water pump 38, and at the same time positively influence the weight distribution in the vehicle 90.
    8 shows a variant embodiment in which the electric machine 14 and the rotary piston internal combustion engine 1 are arranged one behind the other in the cooling circuit 50a of the cooling system 50, wherein a first coolant flow sir which represents approximately 70% to 90% of the total volume flow entering or leaving the generator unit 40 S of the cooling circuit 50a, at least predominantly on the electro-side cooling channel arrangement 51 of the electric machine 14 and possibly also a power electronics 41 is directed past.
    A second coolant stream S2 with only about 10% to 30% of the total volume flow S flows through the electro-side cooling channel arrangement 51. The two coolant streams St and S2 flow through the first piston-side cooling channel arrangement 52 and the central cooling channel arrangement 53 on separate cooling channels and merge in the region of the second piston-side Cooling duct arrangement 54 to a common volume flow S, which is possibly performed downstream of the rotary piston internal combustion engine 1 by an oil cooler 35.
