The compressor 2 includes a casing 21 and an impeller 22. The impeller 22 is disposed within the housing 21. The impeller 22 may be a centrifugal impeller 22. The housing 21 is provided with an inner cavity and an air inlet 211 communicating with the inner cavity. The housing 21 is attached to the casing 11 of the motor 1, and the spindle 13 of the motor 1 extends into the housing 21. The impeller 22 is fitted around the main shaft 13 of the motor 1. The air inlet 211 may be arranged on a side of the housing 21 facing away from the motor 1, and the air inlet 211 may be arranged coaxially with the impeller 22.
The controller 3 is used for controlling the motor 1 to work. The controller 3 includes a housing 31, an air duct 30, and electronics 34. The housing 31 is arranged on the side of the housing 21 of the compressor 2 facing away from the electric machine 1. The casing 31 and the casing 31 of the compressor 2 are connected with each other, and the casing 31 and the compressor 2 can be detachably connected. The air duct 30 includes an air inlet duct 32, an air outlet duct 35, and a baffle 33. The air inlet duct 32 may be a straight duct. The air inlet duct 32 includes an air inlet end 321 and an air outlet end 322. The air outlet end 322 of the air inlet duct 32 is connected to the air inlet 211 of the casing 21 of the compressor 2, and the air inlet end 321 of the air inlet duct 32 is communicated with the outside of the casing 31. The intake duct 32 may be coaxial with the impeller 22. An air outlet 323 is arranged on the side wall of the air inlet pipeline 32. The air outlet 323 extends through the side wall of the air inlet duct 32. The air outlet duct 35 may be a straight duct. One end of the air outlet pipe 35 is connected to the air outlet 323, and the other end of the air outlet pipe 35 is connected to the outside of the housing 31. The cross section of the air outlet duct 35 is rectangular. The extending direction of the air outlet duct 35 is perpendicular to the extending direction of the air inlet duct 32.
The baffle 33 is constructed as a plate-like structure. A baffle 33 is disposed within the air inlet duct 32. The baffle 33 serves to guide part of the air flow in the air inlet duct 32 into the air outlet duct 35. The air deflector 33 is connected to one side of the air outlet 323 close to the air outlet end 322. The baffle 33 slantingly extends from the side of the air outlet 323 close to the air outlet end 322 to the air inlet end 321. That is, the angle between the baffle 33 and the direction of extension of the air inlet duct 32 is less than 90 °, and preferably less than or equal to 45 °.

The electronic components 34 are in contact with the side walls of the air outlet duct 35. The electronic components 34 may be electrically connected to the electric machine 1.
The controller 3 drives the main shaft 13 of the motor 1 to rotate, and when the main shaft 13 of the motor 1 rotates, the impeller 22 is driven to rotate, so that negative pressure is formed at the air inlet 211 of the shell 21 of the compressor 2. When negative pressure is formed at the air inlet 211, outside air is sucked from the air inlet end 321 of the air inlet duct 32, and flows towards the air outlet end 322 of the air inlet duct 32, the air deflector 33 guides a part of air into the air outlet duct 35, and the other part of air enters the air inlet 211 of the housing 21 from the air outlet end 322. The air taken into the intake port 211 is pressurized by the impeller 22 and then sent out to the internal combustion engine. The air introduced into the air outlet duct 35 flows through the air outlet duct 35 and is discharged to the outside of the housing 31.
When the controller 3 drives the motor 1 to work, the electronic device 34 of the controller 3 generates heat, and the electronic device 34 transfers the heat to the side wall of the air outlet pipeline 35. The air flowing through the air outlet duct 35 brings the heat on the side wall of the air outlet duct 35 out of the housing 31, thereby realizing the air cooling of the electronic device 34. Because the electronic device 34 is cooled by air cooling, the power output by the electronic device 34 can be larger, and the power of the electric supercharger can be further increased.
The electronic device 34 is arranged on the outer sides of the air outlet pipeline 35 and the air inlet pipeline 32, the air in the air outlet pipeline 35 and the electronic device 34 are separated from each other by the side wall of the air outlet pipeline 35 and the side wall of the air inlet pipeline 32, so that the electronic device 34 can be prevented from being wetted by water carried in the air, meanwhile, the electronic device 34 is also arranged in the shell 31, and the shell 31 can be dustproof and waterproof, so that the waterproof grade of the controller 3 can be improved, and the waterproof grade of the controller 3 can reach the IP67 standard.
In an exemplary embodiment, the air outlet 323, the air deflector 33 and the air outlet duct 35 are provided in plural numbers on the side wall of the air inlet duct 32. The air outlet 323, the guide plate 33 and the air outlet pipeline 35 are the same in number. The plurality of air deflectors 33 are arranged at the plurality of air outlets 323 in a one-to-one correspondence manner, and the plurality of air outlet pipes 35 are connected to the plurality of air outlets 323 in a one-to-one correspondence manner.

In an exemplary embodiment, the angle between the baffle 33 and the direction of extension of the air inlet duct 32 is adjustable. The baffle 33 may be pivotally attached to the inner wall of the air inlet duct 32.
The electric supercharger further includes a drive mechanism (not shown in the drawings). The drive mechanism may be a servo motor. The driving mechanism can drive the baffle 33 to rotate to control the included angle between the baffle 33 and the extending direction of the air inlet duct 32. The angle of the included angle is inversely related to the rotation speed of the motor 1, for example, the driving mechanism adjusts the angle of the included angle to be smaller as the rotation speed of the motor 1 is larger.
The controller 3 is configured to drive the diversion plate 33 to rotate through the driving mechanism when the rotating speed of the motor 1 is reduced, so that the included angle between the diversion plate 33 and the extending direction of the air inlet pipeline 32 is increased; when the rotating speed of the motor 1 is increased, the guide plate 33 is driven to rotate by the driving mechanism, so that the included angle between the guide plate 33 and the extending direction of the air inlet pipeline 32 is reduced.
Thus, when the rotation speed of the motor 1 is reduced, the wind speed in the air inlet duct 32 decreases, and the controller 3 drives the driving mechanism to rotate the guide plate 33 so as to increase the included angle between the guide plate 33 and the extending direction of the air inlet duct 32, so that the wind volume entering the air inlet duct 32 does not decrease along with the decrease of the wind speed in the air inlet duct 32, and the heat dissipation effect remains unchanged. When the rotating speed of the motor 1 is increased, the wind speed in the air inlet pipeline 32 rises, the controller 3 drives the driving mechanism to rotate the guide plate 33 so as to reduce the included angle between the guide plate 33 and the extending direction of the air inlet pipeline 32, so that the air quantity entering the air inlet pipeline 32 is not too much to influence the air supply efficiency of the compressor 2 to the internal combustion engine, and meanwhile, the heat dissipation effect can be kept unchanged.
In an exemplary embodiment, as shown in fig. 2, a heat dissipating rib 351 is disposed on an inner wall of the air outlet duct 35. The heat dissipation ribs 351 may be configured in a plate-shaped structure. After the electronic device 34 transmits the heat to the side wall of the air-out duct 35, the heat dissipation rib 351 can transmit the heat to the air in the air-out duct 35, and the heat dissipation rib 351 equivalently increases the contact area between the air-out duct 35 and the air, thereby improving the heat dissipation effect.
In an exemplary embodiment, the heat dissipating ribs 351 are provided as strip-shaped plates. The heat dissipating ribs 351 extend along the air outlet duct 35. The opposite sides of the heat dissipating ribs 351 are connected to the inner wall of the air outlet duct 35, respectively. The heat dissipating ribs 351 may be provided in plurality. The plurality of heat dissipation ribs 351 are parallel to each other. The heat dissipation ribs 351 divide the inner cavity of the air outlet duct 35 into a plurality of sub-flow channels 352 parallel to each other, and the air entering the air outlet duct 35 from the air inlet duct 32 flows along the plurality of sub-flow channels 352, so that the heat dissipation effect can be further improved.
In an exemplary embodiment, a water cooling channel 111 is provided in a sidewall of the cabinet 11. The water cooling flow passage 111 may extend around the circumference of the housing 11. The two ends of the water-cooling flow passage 111 are respectively provided with a water inlet and a water outlet.
The electric supercharger further includes a water supply device (not shown in the drawings). The water supply device is used for injecting water to the water inlet of the cold water flow passage and receiving the water output by the water outlet.
The motor 1 generates a large amount of heat during operation, and the water supply device injects water into the water-cooling flow passage 111 of the housing 11, and the water can take away a large amount of heat to lower the temperature of the motor 1.
