[0002] With the acceleration of urbanization, the construction industry has an increasing demand for aerial work equipment. Aerial platform operations are not limited to the construction industry, but are also widely used in advertising installation, municipal maintenance, landscaping, high-altitude power generation and other fields. In order to meet these needs, aerial work platforms came into being. Among these devices, the drive system is one of the core components. Among them, permanent magnet motors have gradually become the main power source for aerial work platforms due to their high efficiency, high reliability and low maintenance costs.

[0003] In order to maintain the internal temperature of the permanent magnet motor, air is generally supplied at the rear of the motor to cool the inside of the motor; however, due to the complex operating environment of the high-altitude platform, such as the decrease in temperature causing the relative humidity of the gas to increase or the occurrence of cloudy and rainy weather, the inside of the motor will become moist during the heat dissipation process.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] Figure 1 The external structure diagram of the permanent magnet motor for aerial platform operation vehicle is shown; Figure 1 In the figure, the permanent magnet motor specially used for aerial platform working vehicle comprises a shell 100 and a cover body 200 installed at the rear of the shell 100.

[0033] Figure 2 shows a schematic diagram of the internal structure of the housing 100; Figure 2 In the embodiment, a rotor 110 and a stator 120 are installed inside the housing 100, and the stator 120 coaxially surrounds the outside of the rotor 110; the above is the basic structure of a motor, that is, the prior art, which is not protected by this application and will not be described in detail.

[0034] Continue to see Figure 2 A fan 130 is installed at the tail of the rotor 110, and the output direction of the fan 130 is from the inside of the shell 100 to the outside of the shell 100; the heat dissipation method of actively introducing cold air from the outside to the inside in the prior art is changed to discharge hot air from the inside to the outside, which releases heat faster.

[0035] In the permanent magnet motor specially used for aerial platform work vehicles, the cover body 200 is provided with: an air supply channel 300 for sending external cold air into the shell 100; an exhaust channel 400 for discharging the hot air in the shell 100; a heat exchange area 500, connecting the air supply channel 300 and the exhaust channel 400, for heat exchange between cold air and hot air; the hot air in the shell 100 can be discharged, and the external cold air can be introduced, so that the heat dissipation efficiency is doubled, and because the cold air will exchange heat with the hot air before entering the shell 100, the temperature of the cold air will increase and the relative humidity will decrease, effectively preventing the inside of the shell 100 from being damp.

[0036] Figure 7 shows a schematic structural diagram of the heat exchange zone 500; Figure 7 In the figure, the heat exchange area 500 includes: a first area 510, which is connected to the air supply channel 300 and filled with cold air; a second area 520, which is connected to the exhaust channel 400 and filled with hot air; a heat exchange plate 530, which is arranged at intervals between the first area 510 and the second area 520 and enables heat exchange between cold air and hot air; the first area 510 and the second area 520 are both a accommodating space opened in the cover body 200, which is used to retain cold and hot air, thereby extending the heat exchange time; the heat exchange plate 530 is a metal sheet spaced between the first area 510 and the second area 520, and has good thermal conductivity, such as aluminum, copper, etc.; the surface can also be treated to increase the coating, which will not be described in detail in this application.

[0037] Continue to see Figure 7 The heat exchanger 530 has a protruding fin 540 on its end surface facing the first area 510 and the second area 520, and the first area 510 and the second area 520 have a fin 550 that matches the fin 1 540; the fin 1 540 and the fin 2 550 are arranged alternately to form a corrugated channel; the fin 1 540 extends into the first area 510 and the second area 520, but it still has a gap allowing gas to flow, and the fin 2 550 extends toward the heat exchanger 530, so the gap formed by the fin 1 540 and the gap formed by the fin 2 550 are staggered, and when the fin 1 540 and the fin 2 550 are staggered, a corrugated channel for gas circulation can be formed, thereby extending the gas circulation path and increasing the possibility of gas contact with the heat exchanger 530 and the fin 1 540, thereby improving the heat exchange effect.

[0038] Figure 3 A schematic structural diagram of the air supply channel 300 is shown; Figure 3In the embodiment, the air supply channel 300 includes a cold air input channel 310 and a cold air output channel 320. The input end of the cold air input channel 310 is connected to the outside, and the output end is connected to the second area 520; the cold air outside can be sent into the second area 520; the input end of the cold air output channel 320 is connected, and the output end of the cold air output channel 320 is connected to the inside of the shell 100; the cold air after heat exchange can be sent into the shell 100; the output end of the cold air input channel 310 and the input end of the cold air output channel 320 are staggered, which is to extend the flow path of the cold air in the second area 520, thereby improving the heat exchange effect; for example, Figure 3 As shown in the figure, the second area 520 is configured as a cylindrical structure, the output end of the cold air input channel 310 is arranged at the central axis of the cylinder, and the input end of the cold air output channel 320 is arranged at the outer edge of the cylinder, so as to extend the circulation path of the cold air; but in some other embodiments, the shape of the second area 520, the output end position of the cold air input channel 310 and the input end position of the cold air output channel 320 are not restricted, and can be set as needed, as long as misalignment occurs.

[0039] Combination Figure 2 and Figure 3 The output end of the cold air output channel 320 is arranged at the head of the shell 100; that is, the supplied cold air enters the shell 100 from the head of the shell 100 and is discharged from the tail of the shell 100, so that the cold air can comprehensively cool the rotor 110 and the stator 120; the cold air output channel 320 includes a starting section 321, a cooling section 322 and a bending section 323, and the cooling section 322 is arranged on the outer periphery of the shell 100; since the cooling section 322 is directly arranged on the outer periphery of the shell 100, the cold air after heat exchange will be cooled again when passing through, forming low-temperature dry air to pass into the shell 100.

[0040] Figure 4 The cooling section 322 is shown as an annular structure. In one embodiment, the cooling section 322 is arranged in an annular structure; this can retain the condensed water droplets.

[0041] Figure 5 The cooling section 322 is shown as a spiral structure; in another embodiment, the cooling section 322 is configured as a spiral structure; this can extend the cooling path.

[0042] Figure 6 A schematic structural diagram of the exhaust passage 400 is shown; Figure 6In the figure, the exhaust channel 400 includes a hot air input channel 410 and a hot air output channel 420, the input end of the hot air input channel 410 is connected to the rear of the shell 100, the output end of the hot air input channel 410 is connected to the fin 540, the input end of the hot air output channel 420 is connected to the fin 540, and the output end of the hot air output channel 420 is connected to the outside of the shell 100; the hot air in the shell 100 can enter the fin 540 through the hot air input channel 410, and after heat exchange with the fin 540, it is discharged to the outside of the shell 100 through the hot air output channel 420; the hot air output channel 420 and the cold air input channel 310 are coaxially arranged, so that the two can exchange heat again to preheat the cold air in the cold air input channel 310 in advance.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
