摘要： The invention relates to a housing (10) for an electrical machine (50) and to an electrical machine (50) having such a housing (10). The housing (10) comprises an inner wall (12) and an outer wall (14), with a hollow space (16) therebetween for cooling the electrical machine (50) with a fluid. The housing (10) further has a sealing device (24, 26) on a front face (22, 23) of the housing (10). The housing is particularly characterised in that the sealing device (24, 26) comprises an annular sealing element (28) mounted between the inner wall (12) and the outer wall (14) so as to seal the front face, and in that the sealing device (24, 26) comprises a deflection ridge (30) which projects from the sealing element (28) in the axial direction of the housing (10) and is at least partially arranged between the walls (12, 14), the deflection ridge (30) being designed to lead a cooling fluid in the hollow space (16). A compact, economical and fluid-tight housing (10) can thus be advantageously provided.

摘要： A rotor (1) of an electrical machine is already known, comprising a rotor body (3) which can be rotated about a rotor axis (2) and comprising several cooling ducts (5) which have a cooling duct opening (8.1, 8.2) at each of its ends, wherein one cooling duct opening (8.1) of one of the cooling ducts (5) is arranged radially further outside than the other cooling duct opening (8.2) of the same cooling duct (5). The driving force for generating an airflow through the cooling ducts (5) is generated by a radial offset between a channel of a hollow shaft of the rotor and one of the cooling duct openings of the rotor. In the rotor (1) according to the invention, the driving force for generating the airflow is generated solely in the cooling duct (5) in question of the rotor (1). According to the invention: the first cover element (10) covers the radially innermost partial cross-section of the cooling duct opening (8.1) in question with an edge section which is radially outward with respect to the rotor axis (2) and in each case leaves a radially outermost partial cross-section of the same cooling duct opening (8.1) uncovered as a cooling duct outlet (8.1); the other cooling duct opening (8.2) of the same cooling duct (5) is in each case a cooling duct inlet; an inflow which is axial with respect to the rotor axis (2) is provided in each case upstream of the cooling duct inlets (8.2); and the geometric centre of gravity of the cooling duct outlet (8.1) is in each case offset in the radial direction relative to the rotor axis (2) with respect to the geometric centre of gravity of the cooling duct inlet (8.2) of the same cooling duct (5).

摘要： The invention relates to a heat sink (1) for an electric machine, which heat sink has at least one cooling channel (7), which adjoins an interior (3) surrounded by the heat sink (1). The heat sink (1) is characterized in that the heat sink (1) is designed as a single-piece plate (5) bent into a closed ring, in the case of which plate two opposite abutting surfaces (19, 21) are connected to each other in a fluid-tight manner in the region of a joint (17), wherein a plurality of closed channels (7) extend in the plate (5), which channels extend at an angle to the circumferential direction of the ring in such a way that adjacent channels (7) lead into each other in the region of the joint (17) and thus form a continuous, spiral channel, which extends in a plurality of spiral turns from an axially front end (22) to an axially rear end (24) of the annular heat sink (1). In particular, the plate (5) of the heat sink (1) can be economically extruded and then brought into a shape suitable for the heat sink (1) by means of bending and axial offsetting. The heat sink (1) can be produced in a simple and economical manner and enables efficient cooling of an electric machine while requiring a minimal installation space.
