The bearing seat mounting portion 1214 is used to install the bearing seat. A wind wheel 210 arranged near the bearing seat mounting portion 1214 among the multiple wind wheels 210 may be provided with an axis structure. The axis structure may be rotatably mounted on the bearing seat through a bearing.

[0049] In some embodiments of the present invention, the motor and the bearing are coaxially arranged.

[0050] Specifically, the motor mounting portion 1213 is coaxially arranged with the bearing seat mounting portion 1214. By integrally forming the bearing seat mounting portion 1214, the motor mounting portion 1213, the first shell 121 and the plurality of wind wheel mounting portions 1211, it is beneficial to ensure the coaxiality of the bearing seat mounting portion 1214 and the motor mounting portion 1213, so as to ensure the coaxiality of the motor and the bearing seat, and avoid vibration of the fuselage due to large coaxiality error between the motor and the bearing seat, thereby reducing the wear of the motor and the bearing and increasing the service life of the motor and the bearing.

[0051] Combination Figure 1 and Figure 3In some embodiments of the utility model, the first shell 121 includes a base plate 1216 and a supporting beam 1217, the supporting beam 1217 is arranged perpendicular to the base plate 1216, the supporting beam 1217 is arranged opposite to the air outlet frame 111, and the air outlet 1212 arranged opposite to the air outlet frame 111 is formed on the supporting beam 1217, a part of the wind wheel mounting portion 1211 is formed on the supporting beam 1217, and another part of the wind wheel mounting portion 1211 is formed on the base plate 1216, wherein the supporting beam 1217 can be supported at the position of the air outlet frame 111 to improve the rigidity of the air duct machine housing and reduce the risk of deformation of the air duct machine housing.

[0052] like Figure 2 As shown, in some embodiments of the present invention, the duct machine housing further includes: a partition 130 , which is mounted on the chassis 110 , and is disposed between the air outlet frame 111 and the first shell 121 , and the first shell 121 is connected to the partition 130 .

The partition 130 is installed on the chassis 110 and is located between the air outlet frame 111 and the supporting beam 1217. The partition 130 can be further supported at the position of the air outlet frame 111 to further improve the rigidity of the duct machine housing and reduce the risk of deformation of the duct machine housing. For example: when the dimension of the duct machine housing in the first direction is longer, the duct machine housing requires greater body rigidity to resist deformation. The rigidity of the duct machine housing can be improved by setting the partition 130 to reduce the risk of deformation of the duct machine housing.

[0054] Furthermore, the first shell 121 is connected to the chassis 110 through the partition 130, and a motor mounting portion 1213, a bearing seat mounting portion 1214 and a plurality of wind wheel mounting portions 1211 are formed on the first shell 121, that is, the motor mounting portion 1213, the bearing seat mounting portion 1214 and the plurality of wind wheel mounting portions 1211 can be installed on the chassis 110 through the partition 130, which ensures the rigidity of the duct machine housing and is conducive to improving the assembly convenience of the duct machine housing.

[0056] Specifically, multiple ventilation holes 131 are arranged in sequence along the first direction on the partition 130, and the multiple ventilation holes 131 are arranged one by one with the multiple air outlets 1212. When the motor drives the wind wheel 210 to rotate, the wind wheel 210 drives the airflow to flow, and the airflow can flow into the ventilation holes 131 from the air outlets 1212.

[0057] In some embodiments of the present invention, the chassis 110 is further formed with an installation space, which is provided on a side of the air outlet frame 111 away from the shell assembly 120 and is used for installing a heat exchanger.

[0061] Furthermore, the plurality of wind wheel mounting portions 1211 are spaced apart in the first direction so that two adjacent axial air inlets 1215 can be spaced apart to facilitate airflow into each mounting cavity. In addition, the plurality of second shells 122 are separately arranged and connected one by one with the plurality of wind wheel mounting portions 1211 to effectively prevent the airflow from entering the mounting cavity due to the connection of the plurality of second shells 122, thereby ensuring air intake efficiency.

[0062] The duct unit 10 of the present invention includes the duct unit housing mentioned above.

[0063] Since the duct machine 10 is provided with the above-mentioned duct machine housing, the first shell 121 is formed with multiple wind wheel mounting parts 1211 to simplify the component arrangement of the duct machine housing, thereby simplifying the assembly process of the duct machine housing, improving the production and assembly efficiency of the duct machine housing, and being beneficial to ensuring the coaxiality of the multiple wind wheel mounting parts 1211, thereby being beneficial to ensuring the coaxiality of the multiple wind wheels 210.
