The electric machine assembly 3 according to the utility model embodiment is described in detail below with reference to Fig. 1 and Fig. 2.
As depicted in figs. 1 and 2 (direction of arrow is the flow direction of air-flow), according to the electric machine assembly 3 of the utility model first aspect embodiment, comprise motor 31, first motor cover 32, second motor cover 33 and the 3rd motor cover 34.Further, above-mentioned electric machine assembly 3 also comprises air inlet 42, and air-flow enters in motor 31 through air inlet 42.
Specifically, be formed with motor container cavity 321 in the first motor cover 32, motor 31 is located in motor container cavity 321, and the air-flow of going out via motor 31 first flows in the space that limits between the first motor cover 32 and motor 31.Second motor cover 33 covers on the outside of the first motor cover 32, and forms the first air channel 43 being communicated with motor container cavity 321 between the second motor cover 33 with the first motor cover 32.Thus, the air-flow in the first motor cover 32 can flow in the first air channel 43.3rd motor cover 34 covers on the outside of the second motor cover 33, forms the second air channel 44 being communicated with the first air channel 43 between the 3rd motor cover 34 with the second motor cover 33.Thus, the air-flow in the first air channel 43 can flow in the second air channel 44.
Distance between the perisporium of Distance geometry second motor cover 33 at least partially and between the perisporium of the second motor cover 33 of the perisporium of the 3rd motor cover 34 and the perisporium of the first motor cover 32 is unequal.Thus, when in the first motor cover 32, air-flow out flows through the first air channel 43 and the second air channel 44 successively, air-flow can be made through the air channel of Different Diameter to cross-sectional sizes, thus air-flow can be made to change frequency and the wave amplitude of air-flow by the mode that segmentation is expanded, reduce air velocity, thus effectively can reduce noise.
According to the electric machine assembly 3 of the utility model embodiment, be set to unequal by the distance between the perisporium of Distance geometry second motor cover 33 at least partially and between the perisporium of the second motor cover 33 of the perisporium by the 3rd motor cover 34 and the perisporium of the first motor cover 32.Thus, when motor 31 air-out, air-flow can through the air channel of Different Diameter to cross-sectional sizes, thus the mode that can be expanded by segmentation reduces the speed of air-flow, and then can reduce noise.
According to embodiments more of the present utility model, as depicted in figs. 1 and 2, the distance at least partially and between the perisporium of the second motor cover 33 of the perisporium of the 3rd motor cover 34 is greater than the distance between the perisporium of the second motor cover 33 and the perisporium of the first motor cover 32.Thus, air-flow can realize expanding further at the spacing larger part of the 3rd motor cover 34 and the second motor cover 33, thus can reduce frequency and the wave amplitude of air-flow, and can reduce the speed of air-flow further, and then can reduce noise.
According to embodiments more of the present utility model, as depicted in figs. 1 and 2, the distance between the perisporium of Distance geometry first motor cover 32 at least partially and between the perisporium of the second motor cover 33 of the perisporium of the first motor cover 32 and motor 31 is unequal.That is, the width of at least part of radial section in the first air channel 43 and distance between the first motor cover 32 perisporium and motor 31 unequal.Thus, when air-flow flows in the first air channel 43 in the first motor cover 32, air-flow through the flow channel of different radial section sizes, thus can change frequency and the wave amplitude of air-flow, and then can the noise that produces of loss motor 31.
Further, the distance at least partially and between the perisporium of the second motor cover 33 of the perisporium of the first motor cover 32 is less than the distance between the perisporium of the first motor cover 32 and motor 31.That is, the width of at least part of radial section in the first air channel 43 is less than the distance between the first motor cover 32 perisporium and motor 31.Thus, when air-flow flows in the first air channel 43 in the first motor cover 32, chaotic air-flow in the first motor cover 32 can be made to enter after in the first air channel 43 and to become orderly, thus can noise be reduced.
Preferably, as shown in Figure 2, the distance between the perisporium of the distance between the perisporium of the first motor cover 32 and motor 31, distance between the perisporium of the first motor cover 32 and the perisporium of the second motor cover 33 and the second motor cover 33 and the perisporium of the 3rd motor cover 34 is all unequal.Thus, the air-flow spilt out from motor 31 can be made through all unequal flow channel of radial section size, and the mode expanded by multistage segmentation changes frequency and the wave amplitude of air-flow, and can further loss motor 31 produce noise.
According to embodiments more of the present utility model, with reference to Fig. 2 composition graphs 1, distance between the perisporium of the first motor cover 32 and motor 31 is not less than 4 millimeters (with reference to the distance in Fig. 2 a), distance between the perisporium of the second motor cover 33 and the perisporium of the first motor cover 32 is not less than 3 millimeters (the distance b with reference in Fig. 2), and the distance between the perisporium of the 3rd motor cover 34 and the perisporium of the second motor cover 33 is not less than 5 millimeters (the distance c with reference in Fig. 2).Be understandable that, first the air-flow of going out from motor 31 flows in the space that limits between the first motor cover 32 and motor 31, because the speed of the air-flow spilt out from motor 31 is larger, therefore comparatively large (being not less than 4 millimeters with reference to the distance a in Fig. 2) that the distance between the perisporium of the first motor cover 32 and motor 31 is arranged, time in the space that the larger air-flow of speed can be made thus to flow into limit between the first motor cover 32 and motor 31, the larger air-flow of speed can be made to reduce its flowing velocity by the mode expanded, thus frequency and the wave amplitude of air-flow can be changed, and then can noise be reduced.
When air-flow flows out and flows in the first air channel 43 of limiting between the first motor cover 32 and the second motor cover 33 in the first motor cover 32, due to less (being not less than 3 millimeters with reference to the distance b in Fig. 2) that the distance between the perisporium of the second motor cover 33 and the perisporium of the first motor cover 32 is arranged, the air-flow in inflow first air channel 43 can be made thus to become orderly state from the state of confusion, thus can noise be reduced.When air-flow to flow out from the first air channel 43 and flows in the second air channel 44 of limiting between the second motor cover 33 and the 3rd motor cover 34, due to maximum (being not less than 5 millimeters with reference to the distance c in Fig. 2) that the distance between the perisporium of the 3rd motor cover 34 and the perisporium of the second motor cover 33 is arranged, the air-flow in inflow second air channel 44 can be made thus to be further advanced by expansion fashion and to reduce its flowing velocity, thus frequency and the wave amplitude of air-flow can be changed, and then noise can be reduced.
What need here to illustrate is, expansion in the space that the expansion of air-flow in the second air channel 44 and air-flow limit between the first motor cover 32 and motor 31 has difference, expansion in the space that air-flow limits between the first motor cover 32 and motor 31 is the expansion be under confusing state, and the expansion of air-flow in the second air channel 44 is the expansion of orderly air-flow, the noise of now air-flow generation is lower.That is, air-flow, by the process of expansion, ordering, reflation, can reduce noise effectively.In addition, " larger ", " less ", " maximum " of above-mentioned three kinds of distances (distance a, distance b, distance c with reference to Fig. 2) is comparatively speaking.
According to embodiments more of the present utility model, as shown in Figure 1, first motor cover 32 is formed with the first ventilating opening 322, can be communicated with by the first ventilating opening 322 between above-mentioned motor container cavity 321 with the first air channel 43, the air-flow in the first motor cover 32 is flowed in the first air channel 43 by the first ventilating opening 322.And the second motor cover 33 is formed with the second ventilating opening 331, first air channel 43 and is communicated with by the second ventilating opening 331 with between the second air channel 44, the air-flow in the first air channel 43 is flowed in the second air channel 44 by the second ventilating opening 331.First ventilating opening 322 is arranged in the relative both sides of motor 31 with the second ventilating opening 331, thus, can extend the flow path of air-flow, thus noise losses can be made larger, and then can play the effect reducing noise further.
Such as, in the example of fig. 1, the second ventilating opening 331 and the first ventilating opening 322 are arranged in the upper side and lower side of motor 31.First ventilating opening 322 is formed as multiple first venthole 3221, and multiple first venthole 3221 is uniformly distributed along the axial and circumferential directions on the part perisporium of the first motor cover 32.Alternatively, the first venthole 3221 is formed as strip.Second ventilating opening 331 is formed as multiple second venthole 3311, and multiple second venthole 3311 is uniformly distributed along the axial and circumferential directions on the part perisporium of the second motor cover 33.Alternatively, the second venthole 3311 is formed as circular.The shape of the first venthole 3221 and the second venthole 3311 can also be formed as other shape, such as oval.Certainly, the first ventilating opening 322 and the second ventilating opening 331 can also be an opening respectively.
Further, as shown in Figure 1, the 3rd motor cover 34 comprises the first kuppe 341 and the second kuppe 342.The outside that first kuppe 341 covers on the second motor cover 33 also and between the second motor cover 33 forms the second air channel 44, outlet 441 and second ventilating opening 331 in the second air channel 44 are arranged in the relative both sides (both sides up and down with reference to Fig. 1) of motor 31, the flow path of air-flow can be extended thus further, thus can loss noise further, and then noise can be reduced.
Second kuppe 342 is located at the outside of the first kuppe 341, form exhaust air flue 45 between second kuppe 342 and the first kuppe 341, between one end (front end with reference in Fig. 1) of the second kuppe 342 and the second motor cover 33, form the entrance 451 of exhaust air flue 45.Thus, the air-flow flowed out from the second ventilating opening 331 the second motor cover 33 flows in the second air channel 44 of being formed between the second motor cover 33 and the first kuppe 341, and the air-flow in the second air channel 44 is flowed in exhaust air flue 45 by the outlet 441 in the second air channel 44, the entrance 451 of exhaust air flue 45 more successively.
Preferably, distance between second kuppe 342 and the perisporium of the second motor cover 33 is greater than the distance between the perisporium of the first motor cover 32 and the perisporium of the second motor cover 33, and increases gradually along the flow area of air-out direction (with reference to the direction shown in arrow in exhaust air flue 45 in Fig. 1) exhaust air flue 45.Thus, the cross-sectional width of the entrance 451 of exhaust air flue 45 is greater than the radial section width in the first air channel 43, and when air-flow flows into entrance 451 place of exhaust air flue 45 through the first air channel 43 and the second air channel 44, air-flow can produce expansion herein.Simultaneously owing to increasing gradually along the flow area of air-out direction exhaust air flue 45, the air-flow flowing into exhaust air flue 45 can continue to expand in the process flowed along air-out direction, thus the mode again by expanding reduces the flow velocity of air-flow and the frequency of air-flow and wave amplitude further, and then noise can be reduced further.
