DETAILED DESCRIPTION

[0031] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the embodiments.

[0032] Figure 1 A structural diagram of the external structure of the high-altitude platform working vehicle dedicated permanent magnet motor is shown; Figure 1 In the high-altitude platform working vehicle dedicated permanent magnet motor, a housing 100 and a cover 200 installed at the tail of the housing 100 are included.

[0033] Figure 2 A structural diagram of the internal structure of the housing 100 is shown; Figure 2 In the housing 100, a rotor 110 and a stator 120 are installed inside the housing 100, and the stator 120 is coaxially and circumferentially arranged outside the rotor 110; the above is the basic structure of a motor, i.e., the prior art, which is not protected by the present application and will not be described again.

[0034] Continuing to refer to Figure 2 The rotor 110 is provided with a fan 130 at the tail, and the output direction of the fan 130 is from the inside of the housing 100 to the outside of the housing 100; the heat dissipation mode of the prior art, i.e., actively introducing cold air from the outside to the inside, is changed to exhaust hot air from the inside to the outside, so that the heat is released faster.

[0035] The high-altitude platform working vehicle special permanent magnet motor, the cover 200 is provided with: air supply channel 300, for sending the outside cold air into the shell 100; Exhaust air passage 400, for the hot air in the shell 100 is discharged; Heat exchange area 500, the air supply channel 300 and the exhaust air passage 400 are communicated, for the cold air and the hot air exchange heat; Both the hot gas 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 exchanges heat with the hot air before entering the shell 100, the temperature of the cold air rises and the relative humidity decreases, effectively preventing the inside of the shell 100 from being damp.

[0036] Figure 7 The structure diagram of the heat exchange area 500 is shown; Figure 7 The heat exchange area 500 includes: the first area 510, the air supply channel 300 is communicated and filled with cold air; The second area 520 is communicated with the exhaust air passage 400 and filled with hot air; The heat exchange fin 530 is arranged between the first area 510 and the second area 520 and exchanges heat between the cold air and the hot air; The first area 510 and the second area 520 are both a containing space in the cover 200, for storing cold and hot air, thereby prolonging the heat exchange time; The heat exchange fin 530 is a metal sheet spaced between the first area 510 and the second area 520, which has good heat conductivity, such as aluminum, copper, etc.; The surface can also be treated to increase the coating, which is not described in detail.

[0037] Continuing to refer to Figure 7 The end face of the heat exchange fin 530 towards the first area 510 and the second area 520 has a protruding fin 540, and the first area 510 and the second area 520 have a fin 550 matched with the fin 540; The fin 540 and the fin 550 are staggered and form a wave-shaped channel; The fin 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 550 extends towards the heat exchange fin 530, so the gap formed by the fin 540 and the gap formed by the fin 550 are staggered, and when the fin 540 and the fin 550 are staggered, a wave-shaped channel for gas flow is formed, thereby prolonging the flow path of the gas and increasing the possibility of gas contacting the heat exchange fin 530 and the fin 540, improving the heat exchange effect.

[0038] Figure 3 The structure diagram of the air supply channel 300 is shown; Figure 3In the embodiment shown in the figure, the air supply passage 300 comprises a cold air input passage 310 and a cold air output passage 320. The input end of the cold air input passage 310 is connected to the outside, and the output end is connected to the second area 520, so that cold air from the outside can be supplied into the second area 520. The input end of the cold air output passage 320 is connected to the outside, and the output end is connected to the inside of the shell 100, so that the cold air after heat exchange can be supplied into the shell 100. The output end of the cold air input passage 310 is arranged in a staggered manner with the input end of the cold air output passage 320, so as to prolong the flow path of the cold air in the second area 520, thereby improving the heat exchange effect. For example, Figure 3 In the embodiment shown in the figure, the second area 520 is arranged in a cylindrical structure, the output end of the cold air input passage 310 is arranged at the central axis of the cylinder, and the input end of the cold air output passage 320 is arranged at the outer edge of the cylinder, so as to prolong the flow path of the cold air. However, in some other embodiments, the shape of the second area 520, the position of the output end of the cold air input passage 310, and the position of the input end of the cold air output passage 320 are not limited, and can be arranged as needed, as long as they are staggered.

[0039] In combination with Figure 2 and Figure 3 , the output end of the cold air output passage 320 is arranged at the head of the shell 100. That is, the cold air supplied into the shell 100 from the head of the shell 100 and discharged from the tail of the shell 100, so that the cold air can fully cool the rotor 110 and the stator 120. The cold air output passage 320 comprises a starting section 321, a cooling section 322, and a return section 323. 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 entering the shell 100.

[0040] Figure 4 The cooling section 322 is shown in a ring structure. In one embodiment, the cooling section 322 is arranged in a ring structure. In this way, water droplets condensed can be retained.

[0041] Figure 5 The cooling section 322 is shown in a spiral structure. In another embodiment, the cooling section 322 is arranged in a spiral structure. In this way, the cooling path can be prolonged.

[0042] Figure 6 The structure of the air exhaust passage 400 is shown in the figure. Figure 6In the embodiment, the air exhaust channel 400 comprises a hot air input channel 410 and a hot air output channel 420, the input end of the hot air input channel 410 is communicated with the tail of the shell 100, the output end of the hot air input channel 410 is communicated with the fin 1 540, the input end of the hot air output channel 420 is communicated with the fin 1 540, and the output end of the hot air output channel 420 is communicated with the outside of the shell 100; the hot air in the shell 100 can enter the fin 1 540 through the hot air input channel 410, and is exhausted to the outside of the shell 100 through the hot air output channel 420 after heat exchange of the fin 1 540; the hot air output channel 420 is coaxially sleeved with the cold air input channel 310, so that the two can be heat exchanged again to preheat the cold air in the cold air input channel 310.

[0043] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same.
