- the exhaust ribs 71 of the rear bracket 52 are set to 30 °.
- the ratio T / L of the length of the exhaust hole to the thickness ⁇ ⁇ of the exhaust hole is set to 50% or less, particularly 0.4, on the normal surface of the exhaust hole ribs 61 and 71 in the inclined direction. .
- the ratio of the circumferential widths 11 and 12 of the outermost diameter portion and the innermost diameter portion of the intake hole 64 is made the same as the ratio of the innermost diameter d1 of the hole and the outermost diameter d2 of the hole.
- the inclination angle 0 of the intake hole rib 63 toward the direction opposite to the rotation direction of the rotor with respect to the radiation from is set to 25 ° to 35 °, particularly 30 in the present embodiment.

- ° taper angle In particular, in this embodiment, the key is set to 45 °.
- the intake hole 34 and the intake hole rib 35 on the rear side are opened in the axial direction as in the conventional case, with no particular angle.
- the absolute velocity direction of the cooling air on the intake and exhaust sides was visualized by the foot method.
- This method examines the direction of the cooling air velocity vector from the tuft (thread) path. This verification was performed at a constant generator speed of 300 r / min, which is the maximum temperature of the die of the stage 8 and the commutator 12 whose output is limited.
- the unpleasant high-frequency component was reduced by up to 20 dB in the present invention as compared with the conventional one, and the over-all-one value was reduced by about 2 dB at 7000 to 13000 rotations.
- the output is the value when the temperature rise is the same at the rotation speed SOOOr / min, and the wind noise is the value of 10000 r / min.
- the sample used for this had the same inclination angle as the exhaust hole rib 61 on the front side and the exhaust hole rib 71 on the liya side. According to this, as the inclination angle ⁇ is increased, the output increases up to about 50 °, which is considered to be the optimum angle.
- the velocity vector of the cooling exhaust air has a swirl component and a vector component in the monstrous direction that is the exhaust direction, but it is efficient up to 50 ° near the velocity vector of the cooling exhaust air.
- the side wall of the exhaust hole rib tilts in the direction of discharge, and is open to the vector component in the radial direction. This is likely to be due to resistance and a sudden decrease in air flow.
- the wind noise sound pressure decreases sharply up to around 20 ° 20. Up to 60 ° almost flat, 60 °. Inflection point near, reduced again I will do it. This means that up to around 20 °, the sound pressure decreases more sharply than the interference between the exhaust hole ribs and the exhaust air, and then the velocity vector of the cooling exhaust air and further around 60 °, the sound pressure further decreases. This is probably because the exhaust ribs have a large resistance and the amount of exhaust air decreases sharply.
- the output gradually increases as T / L increases, and then the output sharply drops around the point of inflection near 0.5. This is because the number of exhaust hole ribs increases as the T / L is increased under the condition of the constant thickness of the exhaust hole ribs. It is thought that the effect of dissipating heat is improved. However, even if the T / L is increased to 0.5 or more, the exhaust holes will become smaller, and the output will tend to deteriorate due to the decrease in air flow due to the ventilation resistance.
- the exhaust hole rib is configured to be inclined by 20 ° to 50 ° toward the rotation direction of the rotor, and the rib thickness is 50% or less of the exhaust hole width on the normal to the exhaust hole rib in the inclined direction. Then, it is possible to obtain a generator with excellent output and wind noise.

- the ratio of the circumferential widths 1 1 and 1 2 between the outermost diameter part and the innermost diameter part of the intake hole 6 4 is the same as the ratio of the innermost diameter d1 of the hole and the outermost part d2 of the hole.
- the angle of inclination of the side of the rotation direction side with respect to the axial direction is 10 ° to 20 °.
- the inner peripheral surface on the outermost diameter side of the intake hole is formed with a taper of 40 ° to 50 ° in the axial direction with the inner diameter of the plate of the fan 5 as the base point, Wind noise was reduced because it almost matched the speed vector.
- Figure 8 shows this wind noise reduction effect.
- the wind noise is reduced by pitch-one tone noise due to fan 5.
- the inner peripheral surface of the outermost diameter portion is a tapered surface starting from the inner diameter of the annular plate of the fan 5, the flow is straightened without colliding with the annular plate and smoothly flows into the fan blade portion. .
- the intake holes 34 and the intake hole ribs 35 of the rear bracket 52 are not inclined in the same manner as in the conventional example, but the clearance between the rear bracket 52 and the fan 5 is front. If it is equivalent to the front bracket 51, it is needless to say that the same structure as the intake holes 64 and 63 on the front bracket 51 side can be adopted.
- the pitch of the exhaust holes may be made unequal within the range described above.
- breakage can be prevented without impairing cooling performance and low noise.
- the automotive alternator according to the present invention is useful as a power supply source for various electric devices of a vehicle.
