The air distribution frame 11 and the heat dissipation frame 7 are provided with a cavity 17, the inside of the front end of the ventilation shaft 13 is hollow, the side wall of the front end of the ventilation shaft 13 is provided with a plurality of ventilation openings at a medium angle, the ventilation openings are communicated with the inside of the ventilation shaft 13, a heat dissipation cavity 18 is arranged between the rotor assembly 14 and the stator assembly 16, one side of the heat dissipation cavity 18, which is close to the ventilation openings on the ventilation shaft 13, is provided with an air inlet 21, the whole cross section of the heat dissipation cavity 18 is arranged from wide to narrow to wide as shown in fig. 5, a horizontal thin air channel 20 is arranged between the rotor assembly 14 and the ventilation shaft 13, vertical thin air channels 19 are arranged between the rotor assembly 14, the heat dissipation front plate 4 and the heat dissipation back plate 9, a plurality of second heat dissipation openings 6 are formed in the inner periphery of the front plate 4 at equal angles, a plurality of first heat dissipation openings 5 are formed in the periphery at equal angles, the channel length of the first heat dissipation openings 5 is short, and the channel length of the second heat dissipation openings 6 is long.
The motor has the specific working principle that when the motor works, an internal rotor assembly 14 is connected to a fan 8 through a double-shaft speed increaser 15 in a wind dividing frame 11, the double-shaft speed increaser 15 is connected with the rotor assembly 14 through a connecting piece 22, the motor rotates through the double-shaft speed increaser 15 to keep the output rotating speed at about 5500 so that the cooling efficiency of the whole motor can meet the cooling requirement of the whole motor, external wind enters the motor from a radiating frame 7 of a front plate 1, one part of wind directly enters the central area of the rotor assembly through the wind dividing frame 11, the other part of wind enters a cavity 17, and then enters the wind dividing frame 11 from an air inlet 12 formed in the side surface of the wind dividing frame 11.
Firstly, because the diameter of the fan 8 is larger than that of the air dividing frame 11, the air is directly introduced from the middle and introduced from the air inlet 12 at the side, so that the air inlet area is increased. More air can be introduced into the air separation frame 11 per unit time than the air intake only in the middle.
Secondly, the air flow entering the air dividing frame 11 can be distributed more uniformly by simultaneously entering the air dividing frame from the middle and the side, if only the middle air is taken in, the air flow can form more concentrated columnar air flow in the air dividing frame 11, the existence of the double-shaft speed increaser 15 in the middle of the air dividing frame 11 can block the air from entering, the air circulation difference at different positions in the frame can be larger, and the air entering the side air inlet 12 can be mixed with the middle air, so that the air flow is distributed more uniformly in the air dividing frame 11.
Thirdly, the wind entering from the side air inlet 12 can also assist in radiating the double-shaft speed increaser 15, so that the normal operation of the device is ensured.
The air entering the ventilation shaft 13 enters the air inlet 21 from the periphery, then enters the heat dissipation cavity 18 and the horizontal fine air duct 20 from the air inlet 21 respectively, the air inlet 21 is wider, and the heat dissipation cavity 18 is from narrow to wide when entering the heat dissipation cavity 18, so that the air is blown through the space from wide to narrow to wide, and the following advantages are achieved.
First, when wind enters a relatively narrow space from a wide space, the air flow speed is increased according to the fluid mechanics principle. Inside the machine, the gap temperature between the stator assembly 16 and the rotor assembly 14 is relatively high. The accelerated airflow may more effectively carry away the heat generated by these components.
Second, the wind then re-enters the wider heat dissipation chamber 18, slowing down, which allows more time for heat to dissipate into the surrounding environment. The wider heat dissipation chamber 18 space provides a more adequate place for heat exchange where the air can perform sufficient heat exchange, further reducing the overall temperature inside the motor.
Third, the wide-to-narrow-to-wide flow path of the wind may result in a more orderly airflow inside the motor. In the course of the width to the narrowness, the pressure energy of the gas flow is partly converted into kinetic energy, so that the gas flow obtains a sufficient velocity through the narrow area. After entering a wide area, the kinetic energy can be properly converted into pressure energy, so that the air flow forms stable pressure distribution in the motor, and the heat dissipation effect is improved.
Fourth, the air flow entering the thin air duct 20 can assist in taking away the heat on the surface of the rotating shaft element 10, and the process from the air inlet 21 to the thin air duct 20 and then to the space of the heat dissipation back plate 9 is a process from wide to narrow and then to wide, so that the flow speed of the air flow is improved, and the heat dissipation efficiency is improved.
A part of the air flow in the heat dissipation cavity 18 flows out of the structural gap of the stator assembly 16, is discharged from the side air outlet 3 to take away the heat in the central area of the motor, and a part of the air flow enters the vertical fine air channels 19 on two sides, and the air flow in the vertical fine air channels 19 finally flows out of the heat dissipation back plate 9 and the heat dissipation front plate 4, so that the following advantages are achieved.
Firstly, the air flow entering the vertical fine air duct 19 can take away the heat outside the rotor assembly 14, and the air flow is matched with the side air outlet 3 to take away the heat inside, so that a better heat dissipation effect is achieved.
Second, without the vertical fine air duct 19, hot air may accumulate near the side air outlet 3, forming a localized high temperature region (heat island). The vertical fine air duct 19 can guide part of hot air to other places, so that the hot air is prevented from accumulating in one place, and the heat dissipation efficiency is improved.
Third, the bent vertical fine air duct 19 changes the direction of the air flow, so that the air forms more complex convection around the outside of the rotor assembly 14. When the hot air flows in the vertical fine air duct 19, heat exchange with the outside air occurs. Because of the smaller diameter of the vertical fine air duct 19, the time in which the air flows is relatively prolonged, which is advantageous for a sufficient exchange of heat.
The presence of the cavity 17 in combination with the heat dissipation front plate 4 still provides a spatially varying course of wind flow from wide to narrow to wide, increasing the heat dissipation efficiency of the heat dissipation front plate 4.
The wind is discharged from the two air outlets of the heat dissipation front plate 4, the channel length of the first heat dissipation opening 5 passing through is shorter, and the channel length of the second heat dissipation opening 6 passing through is longer, so that the design has the following advantages.
First, the flow of wind generates pressure changes. The short caliber of the first heat radiation port 5 can rapidly reduce the pressure of the heat radiation front plate 4 near the side thereof, while the long caliber of the second heat radiation port 6 reduces the pressure relatively slowly due to the relatively slow air flow discharge. The pressure difference can promote wind to flow more uniformly in the motor, prevent dead angles of air flow and improve heat dissipation efficiency.
And secondly, a part of hot air is discharged from the short-caliber first heat dissipation opening 5, so that heat generated by the motor close to the side can be taken away rapidly. The long-caliber second heat radiation ports 6 then discharge the remaining hot air, and the part of the hot air has more time to exchange heat with the channel walls when passing through the relatively long channels. Just like the object that gives heat falls down twice, take away a part of heat fast earlier, then slowly give off remaining heat, this kind of sectional type heat dissipation mode can improve radiating efficiency.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
