The driver housing 2 includes: the installation cavity 21 provides an installation space for devices inside the driver, and a first annular cavity structure 3 is enclosed among a bottom plate of the installation cavity 21, two installation convex edges 13 and the periphery of the motor shell 1; an air inlet sealing plate 22 is arranged at one end of the bottom of the mounting cavity 21, and is used for partially sealing one end of the first annular cavity structure 3 and limiting air flow from an exhaust fan to enter the first annular cavity structure 3 through one side close to the mounting inner cavity 11; an air outlet sealing plate 14 is arranged on the outer surface of the motor shell 1, the air outlet sealing plate 14 is positioned between the two mounting convex edges 13, and air flow from the first annular cavity structure 3 is limited to leave the first annular cavity structure 3 through one side close to the mounting cavity 21.

The space size of the installation cavity 21 can be set according to the specific internal structure of the driver, so as to realize effective installation as the final purpose, in the invention, the space for realizing double-effect cooling is located in the first annular cavity structure 3, in the installation process, the exhaust fan is covered on one side of the motor shell 1 through the fan cover, only the inlets of the external heat dissipation cavity 12 and the first annular cavity structure 3 are needed to be arranged in the fan cover, thereby the air flow enters the external heat dissipation cavity 12 and the first annular cavity structure 3 simultaneously, the heat generated in the installation inner cavity 11 is taken away by the air flow entering the external heat dissipation cavity 12 in the free flow process, and the air flow entering the first annular cavity structure 3 can pass through the following processes:

referring to fig. 7, the gas entering the first annular cavity structure 3 from the inlet between the air inlet cover plate 22 and the periphery of the motor housing 1 rapidly flows toward the outlet, and a portion of the gas is blocked by the air outlet cover plate 14 in the flow direction, for example, the gas flow in the direction of the direction. Due to the generation of the area, the air flow can be exchanged with heat more completely, so that high heat exchange efficiency can be realized in a small heat exchange space. It should be emphasized here that under the condition of a certain amount of inlet air, the flow rate of the cooling air is not changed, and the change is only an efficiency problem, so that the heat exchange mode has a better heat dissipation effect than the original mode of independently using the exhaust fan.

In the above configuration, the air flow for cooling the driver comes from the exhaust fan provided in the motor, but does not affect the heat dissipation of the motor, but rather increases the cooling effect in the corresponding local area. The external heat dissipation cavities 12 may be evenly distributed around the periphery of the motor housing 1, and the driver housing 2 may be disposed between two adjacent external heat dissipation cavities 12.

Because the air current that discharges from first ring cavity structure 3 also carries certain heat, therefore form local high temperature on motor casing 1 surface hardly to avoid, in order to avoid the influence to the motor, go out air blanking plate 14 and motor casing 1 and be provided with a plurality of fin 15 between the opposite side tip relative to first ring cavity structure 3 position, fin 15 extends along motor casing 1 length direction.

The heat sink 15 is disposed along the direction of the airflow flowing out from the first annular cavity structure 3, so that on one hand, heat in the motor housing 1 is conducted, and on the other hand, the airflow flowing out from the first annular cavity structure 3 can smoothly flow, thereby reducing the problem that the heat dissipation of the motor is blocked or the local part is difficult to dissipate due to the integration of the driver.

For process purposes, the heat sink 15 is integrally formed with the motor housing 1, and the air outlet cover 14 is additionally formed and then installed, specifically, the air outlet cover 14 and the end of the heat sink 15 are fixed by a connector. In this way, the air blocking height of the air outlet sealing plate 14 and the space size of the first annular cavity structure 3 can be adjusted, so that the flexibility and the universality of the heat exchange space in the invention are better.

Aiming at the processing of the combined shell structure, an integral forming mode can be adopted, and the subsequent secondary processing can be carried out aiming at local positions, and a split processing mode can also be adopted; two side edges 25 are arranged at the bottom of the mounting cavity 21, and the two side edges 25 are respectively attached to and fixedly connected with the inner sides of the two mounting convex edges 13. The connection can be realized by adopting screws, the fixing mode is simple and easy, and the installation difficulty of each part can be reduced by adopting a split processing mode.

Preferably, in order to reduce the difficulty of installation when the motor housing 1 and the driver housing 2 are arranged, the bottom of the installation cavity 21 extends towards two sides relative to the side edge 25, and the extending part is attached to the top of the installation convex edge 13, so that the driver housing 2 is positioned in one direction.

In order to fully utilize the advantages of the above structure, the filter closing plate 23 extends toward the mounting cavity 21 to serve as a side wall of the mounting cavity 21. With reference to fig. 8, the extended use of the filter closing plate 23 makes possible the circulation of air inside the installation cavity 21. Because the airflow flowing out of the second annular cavity structure 4 obtains higher pressure in the supercharging region, a higher flow velocity is formed in the region D in fig. 10, and the increase of the flow velocity in this region inevitably drives the air in the region E to flow, such a tendency can cause the air at the bottom layer in the drawing to circulate to the right side in the drawing of the installation cavity 21, and along with the outward circulation of the air at the bottom layer, the installation cavity 21 enters new air through the top in the drawing to form an air circulation form, so that the heat dissipation effect is further improved.
