Shown in Fig. 1 ~ 3, a kind of motor ventilating fan 5 of engine-driven electric generator comprises:
On the outer wall of dish shape wing mounting plate 52, be provided with a plurality of outer wings 53 radially along being on flanging portion 521 and the wind-guiding curved face part 522, the height of this outer wing 53 exceeds the height of wing mounting plate 52; Between dish shape wing mounting plate 52 and fan mounting plate 51, be provided with a plurality of first inner wings 54 of height and the height basically identical of wing mounting plate 52; The inwall of the far-end of this first inner wing 54 and wing mounting plate 52 is that the inside of wind-guiding curved face part 522 fuses, and the lower end one of its near-end is connected on the wing assembly department 515 at fan mounting plate 51 edges.Like this, between adjacent inner wing 54, wind-guiding curved face part 522 and fan mounting plate 51, just limit i.e. first vent hole 56 (like Fig. 2, shown in Figure 3) of a vent hole, so that the air of motor ventilating fan bottom side can lead to opposite side along this first vent hole 56.
In twos between first inner wing 54; Be provided with second inner wing 55 with first inner wing, 54 height such as grade with the mode identical with first inner wing; And make between the near-end elongation line of first inner wing 54 and second inner wing 55 and be an acute angle, in the present embodiment, this acute angle is 20 degree (not shown)s.
Like Fig. 1, shown in Figure 2, in the present embodiment, outer wing 53, first inner wing 54, second inner wing 55 are tabular.
As shown in Figure 3; Motor ventilating fan 5 is in practical application, near the air that is positioned at the fan bottom side can in the top side that exports to motor ventilating fan 5 under the effect of inner wing 54,55 be the proximal lateral of outer wing 53 along first vent hole 56 (air that on the other hand, also has part to be positioned at the fan bottom side can export near the proximal lateral of outer wing 53 through second vent hole 57); Here; After converging with the air of top side, under the effect of outer wing 53, the radial outside along outer wing 53 blows out together.Like this, just reached the purpose of motor ventilating fan 5 two sides air draughts.
As another embodiment of the application of above-mentioned motor ventilating fan 5, motor ventilating fan 5 is used on the engine-driven electric generator, like Fig. 4 ~ shown in Figure 6.
The engine-driven electric generator that the utility model provides, generator 2 rotates with motor 1 coaxial setting and around bent axle 3 one; Motor 1 comprises bent axle 3, casing 4, be positioned at the case lid 41 in casing 4 left sides, be positioned at the upper left quarter of motor 1 and be positioned at generator 2 the top silencing apparatus 11 and cover on around the silencing apparatus 11 to form the muffler cover 12 of silencing apparatus coolant path; That generator 2 comprises is fixed 21, rotor 22 and motor cover 23.Bent axle 3 is fixed on casing 4 and the case lid 41, and rotor 22 is fixed on the bent axle 3 of case lid 41 1 sides and with bent axle and rotates, and stator 21 and the motor cover 23 that connects thereof are fixed on the case lid 41; The axis hole 513 of the motor ventilating fan 5 of aforementioned model utility passes bent axle 3 and is set between generator 2 and the motor 1; It is configured to the wing, and to belong to a side (being the left side of motor ventilating fan 5 among Fig. 4) relative with motor 1; The opposite side of the no wing (being the right side of motor ventilating fan 5 among Fig. 4) and generator 2 is relatively and through four locating columns 512, four mounting holes 511, and a side of the no wing is fixed on the rotor 22 and with rotor 22 rotates.
As shown in Figure 4, offer first intake grill 6 in the bottom of case lid 41, outside air can be along the bottom outer wall of case lid 41, under the guiding of baffle plate 42, near the entering accommodating chamber B near bent axle 3; Near the upper end of case lid 41, offer second intake grill 7, outside air can along the external wall of upper portion of case lid 41 with the proximal lateral of outer wing near relative place get into accommodating chamber B; Exterior edge face in motor cover 23; Offer a plurality of the 3rd intake grills 8 (this intake grill 8 several bar holes in the present embodiment for being circular layout; As shown in Figure 5); Outside air can pass through the 3rd intake grill 8, under the effect of inner wing 53,54, passes near the proximal lateral of generator through the outer wing among first vent hole, the 56 entering accommodating chamber B; In addition, the air that a part is imported by the 3rd intake grill 8 also can be under the action of negative pressure of motor ventilating fan left side, near the proximal lateral through the outer wing among second vent hole, the 57 entering accommodating chamber B.All are from the cooling air of first, second and third intake grill; The effect lower edge radial outside that is incorporated in motor ventilating fan 5 outer wings that in accommodating chamber B, converges is blown into cooling chamber C through pipeline D; And along the outer surface of silencing apparatus 11, near exhaust outlets 9 discharges that form by the gap of muffler cover 12 and silencing apparatus 11 outlet pipe 13 that is positioned at silencing apparatus 11.
Like this, because the case lid 41 lower end outer walls of 6 processes of first intake grill are a sidewall of the machine oil chamber of motor, so can effectively reduce the temperature of engine motor oil through the cooling air of first intake grill 6.Second intake grill is especially under the situation of engine-driven electric generator as mute generator; Its outside also is covered with the sound-insulating cover (not shown) of a relative closure, and motor might heat the air that is positioned at this cover, perhaps has the hot air that spills to enter into space in this cover in the special-purpose coolant path of motor; Like this; If do not extract such hot air out, will have a strong impact on the proper functioning of motor, generator and other electric components (like inverter etc.), thereby; The purpose of second intake grill mainly is the hot air that sucks in this sound-insulating cover space, and takes away the heat of motor 1 or case lid 41 upper end outer surfaces to a certain extent.The external refrigeration wind that the 3rd intake grill 8 sucks then all is used for cooled electric generator 2.Through motor ventilating fan 5 cooling air of part heat that entered absorption among the cooling chamber C, the appearance temperature of the relative silencing apparatus 11 of its temperature is also quite low, in the process of cooling chamber C of flowing through, can continue to take away the heat on silencing apparatus 11 surfaces and discharges from exhaust outlet 9.Thereby the motor ventilating fan 5 through the utility model reaches both cooled electric generators 2, can effectively assist the purpose of cooled engine 1 again.
