It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, it is the embodiment of the present invention provides a structural schematic diagram of a driving integrated machine, which can be applied to the field of power electronic devices, especially in a water pump driving integrated machine. As shown in fig. 2 and 3, the integrated drive machine in the present embodiment includes a motor unit 1 and a driver unit 2, in which: the motor unit 1 includes a motor housing 11, a rotating shaft 12 axially penetrating the motor housing 11, a heat dissipating fan 13 fixed to the rotating shaft 12, and a first air flow passage located at one axial end of the motor housing 11. The heat dissipation fan 13 is located in the first air flow channel, so that the heat dissipation fan 13 can be used as a driving source for driving the heat dissipation module of the all-in-one machine, and external air is sucked from the air inlet of the first air flow channel during operation, and air with a constant flow direction is formed in the first air flow channel, thereby achieving air cooling (a structural mode of performing circulating heat dissipation and cooling by using ambient air as a cooling medium) heat dissipation and cooling.

Further, the driver part 2 includes a driver shell 21 and a heat sink 22 (the heat sink 22 is connected and fixed on the surface of the driver shell 21 facing the motor shell 11), the driver shell 21 is connected and fixed on the outer side of the side wall of the motor shell 11, and a second air flow channel is formed between the driver shell 21 and the motor shell 11, that is, the second air flow channel is located between the motor part 1 and the driver part 2, so that the heat on the motor shell 11 and the driver shell 21 can be simultaneously transferred and dispersed by the air flow flowing through the second air flow channel, and further the heat dissipation and temperature reduction of the motor part 1 and the driver part 2 can be realized.

Particularly, the inlet of the second airflow channel is in butt joint with the first outlet of the first airflow channel (namely, the inlet of the second airflow channel is communicated with the first outlet of the first airflow channel in the driving all-in-one machine), and a heat dissipation air duct taking the inlet of the first airflow channel as an air inlet and the outlet of the second airflow channel as an air outlet is formed. Namely, a main heat dissipation function module of the driving integrated machine is formed by the heat dissipation air channel, and the heat dissipation fan 13 is used as the only driving source of the heat dissipation function module; the driving integrated machine is different from the existing driving integrated machine which is provided with the heat dissipation function modules of two heat dissipation devices, and the driving integrated machine does not need to be additionally provided with a second driving source for heat dissipation design of the driver part 2, so that the structure can be optimized, the structure is simplified, the manufacturing cost is saved, the integration level is improved, and the whole volume is reduced; moreover, the heat radiation fan 13 is arranged on the rotating shaft 12 of the motor part 1, when the motor part 1 operates, the rotating shaft 12 can simultaneously drive the heat radiation fan 13 to rotate, so that heat radiation airflow is formed in a heat radiation air duct to perform heat radiation, the flexibility of internal structure design and application is improved, and the rationality and the practicability of the whole structure are higher.

When the driving all-in-one machine operates, the centrifugal fan 13 rotates along with the rotating shaft 12, air outside the motor shell 11 is sucked from the inlet of the first airflow channel, and flows out from the first outlet of the first airflow channel and enters the second airflow channel through the inlet of the second airflow channel under the rotation driving of the centrifugal fan 13, heat exchange is simultaneously carried out on the motor part 1 and the driver part 2, finally, the air flows out from the outlet of the second airflow channel, and heat on the motor shell 11 and the driver shell 21 is discharged to the outside of the driving all-in-one machine, so that air-cooled integrated circulation heat dissipation and cooling of the driving all-in-one machine are realized.

In addition, the heat radiator 22 of the driver part 2 is located in the heat dissipation air duct, that is, the driver part 2 can transfer and disperse the generated heat to the heat radiator 22, and then the heat dissipation air flow formed in the heat dissipation air duct transfers and disperses the heat on the heat radiator 22, so that the heat radiator 22 can be timely dissipated, the driver part 2 is efficiently cooled, and the heat dissipation effect of the driver part 2 is ensured.

The driving all-in-one machine is provided with the first air flow channel and the second air flow channel, and the first air flow channel and the second air flow channel form the heat dissipation air channel, so that the heat dissipation devices of the motor part 1 and the driver part 2 can be effectively designed in a fusion manner, the overall structure is simplified, the manufacturing cost is reduced, the simultaneous heat dissipation and cooling of the motor part 1 and the driver part 2 are realized, the integration level of the overall structure can be improved while the heat dissipation effect is ensured, the overall size is convenient to reduce, the utilization rate of the installation space is further improved, the application range of the driving all-in-one machine is wider, and the practicability is higher; and the assembly difficulty is favorably reduced, the installation and maintenance operation are more convenient, and the working efficiency is improved.

In another embodiment of the present invention, the first airflow channel further includes a second outlet (the second outlet may be in a ring shape), the second outlet is disposed toward the outer wall of the motor casing 11, and a part of the airflow generated when the heat dissipation fan 13 rotates along with the rotating shaft 12 flows through the surface of the outer wall of the motor casing 11 through the second outlet, so as to dissipate heat of the motor casing 11. That is, the airflow generated by the rotation of the heat dissipation fan 13 is divided into two parts, and one part flows through the heat sink 22 and dissipates heat for the driver part 2; the other part flows through the surface of the motor case 11 and dissipates heat to the motor part 1. Through the structure, the heat radiation fan 13 can radiate heat for the motor part 1 and the driver part 2 at the same time, so that the structure of the integrated drive machine is more compact.

In practical applications, the motor housing 11, the driver housing 21 and the heat sink 22 may be made of a material with high thermal conductivity (e.g., aluminum or aluminum alloy), which is beneficial to efficiently transferring and dispersing heat on the motor portion 1 and the driver portion 2, dissipating heat in time, and reducing temperature, thereby improving the heat dissipation effect on the motor portion 1 and the driver portion 2.

The planes of the inlet and the second outlet of the first air flow channel in the motor part 1 may be both perpendicular to the axial direction of the motor casing, the inlet of the first air flow channel is arranged opposite to the motor casing 11, and the first outlet of the first air flow channel may be located outside the side wall of the motor casing 11. Specifically, the first outlet of the first airflow channel may be located between the heat dissipation fan 13 and the bottom of the driver housing 21, that is, after the heat dissipation fan 13 sucks the air outside the motor housing 11 into the first airflow channel to form the heat dissipation airflow, the first airflow channel is guided into the second airflow channel located between the motor housing 11 and the driver housing 21, so as to ensure the smoothness of the heat dissipation airflow flowing from the first airflow channel to the second airflow channel, and accelerate the circulation flow efficiency of the heat dissipation airflow in the heat dissipation airflow channel.

As shown in fig. 4, in order to ensure that the heat dissipation air flow in the heat dissipation air channel can stably flow from the first air flow channel to the second air flow channel under the action of the heat dissipation fan 13, a fan cover 14 is disposed at one end of the motor portion 1 (the fan cover 14 is mounted and fixed at one end of the motor housing 11 facing the heat dissipation fan 13), and the first air flow channel in the motor housing 11 is located between the motor housing 11, the driver housing 21 and the fan cover 14. The fan housing 14 has an opening 141, and the opening 141 forms an inlet of the first air flow passage, so that when the heat dissipation fan 13 rotates, the ambient air can be sucked into the first air flow passage from the opening 141 of the fan housing 14.

Specifically, when the fan cover 14 is fixedly mounted on the motor casing 11, the fan cover 14 encloses the heat dissipation fan 13 on the end of the motor casing 11, and forms a relatively closed cavity; moreover, the bottom edge of the fan cover 14 facing away from the driver case 21 is an arc-shaped edge (the concave part of the arc-shaped edge faces the driver case 21), which can form a volute-like fan duct, so that the fan cover 14 can protect the heat dissipation fan 13, and meanwhile, the heat dissipation airflow guided by the heat dissipation fan 13 is concentrated and guided into the second airflow channel by the first outlet of the first airflow channel, thereby ensuring the realizability of the guiding function of the heat dissipation airflow by the heat dissipation fan 13, enabling the heat dissipation airflow to stably circulate in the heat dissipation duct, and improving the rationality of the structural design.

In addition, the plane of the first inlet of the first air flow channel and the plane of the outlet of the second air flow channel are both perpendicular to the axial direction of the motor part 1, and the direction of the outlet of the second air flow channel is opposite to the direction of the inlet of the first air flow channel. The planes of the air inlet and the air outlet of the heat dissipation air duct in the driving integrated machine are perpendicular to the axial direction of the motor part 1, and the orientations of the air inlet and the air outlet are opposite, so that the effective contact area between the heat dissipation air duct and the driving integrated machine can be increased, the integral structure is simplified, the flow of heat dissipation air flow in the heat dissipation air duct is smoother, the influence on the circulating flow efficiency of the heat dissipation air flow due to the structural design of the heat dissipation air duct is avoided, and the heat dissipation effect is improved.

In order to improve the heat dissipation effect of the heat dissipation airflow in the heat dissipation air duct on the heat sink 22, a part of the heat sink 22 is disposed in the first airflow channel, and another part is disposed in the second airflow channel. Additionally, the surface of the lateral wall of the motor casing 11 has a plurality of heat dissipation teeth 111 arranged axially, the heat dissipation teeth 111 can increase the heat dissipation area of the motor casing 11, so that the heat on the motor casing 11 can be transferred and dispersed to the outside air in a large area in a heat radiation manner, the motor casing 11 is cooled in time, and at least part of the heat dissipation teeth 111 on the motor casing 11 are positioned in the second airflow channel, so that the heat on the motor casing 11 can be transferred and dispersed by means of the heat dissipation airflow in the second airflow channel, and the heat dissipation effect is improved. Meanwhile, the air flow flowing out from the second outlet of the first air flow channel flows through the gap of another part of the heat dissipation teeth 111, i.e. the gap of the heat dissipation teeth 111 outside the second air flow channel.

The driver housing 21 includes a bottom plate 211 and two parallel first side plates 212, and the first side plates 212 protrude from a surface of the bottom plate 211 facing the motor housing 11. Specifically, the driver case 21 is fixed to the outer side of the side wall of the motor case 11 such that the first side plate 212 is parallel to the axial direction of the motor case 11, and thus, the connection strength between the motor unit 1 and the driver unit 2 can be improved, the heat dissipation area of the driver case 21 can be increased, and the heat dissipation effect on the driver case 21 can be improved. Moreover, the second airflow channel is formed by enclosing the bottom plate 211 of the driver shell 21, the two first side plates 212 and the side wall of the motor shell 11, so that the structure is simple and practical, designability of the structure is improved, and secondary optimization design of the second airflow channel structure is facilitated.

In practical applications, the two first side plates 212 may be fixed to the side walls of the motor housing 11 by screw installation, so that convenience of installation and maintenance disassembly operations may be improved.

The driver housing 21 includes a top cover and a second side plate 213, the second side plate 213 protrudes from a surface of the bottom plate 211 facing away from the motor housing 11, and the second side plate 213, the bottom plate 211 and the top cover enclose a mounting cavity. Furthermore, the driver part 2 further comprises a driving component, and the driving component is installed in a mounting cavity formed by the second side plate 213, the bottom plate 211 and the top cover in an enclosing manner, so that the driving component can be effectively protected from dust, and the damage caused by the aging of accumulated dust can be avoided.

The bottom plate 211 of the driver case 21 has a window. In addition, the heat sink 22 includes a substrate 221 and a plurality of first heat dissipation fins 222 parallel to the first side plate 212, the plurality of first heat dissipation fins 222 are connected to a side surface of the substrate 221, and the substrate 221 is fixed on a surface of the bottom plate 211 facing the motor housing 11 in a manner of sealing the opening window, so that a heat generating component (e.g., a power switch device) in the driving assembly in the driver housing 21 can be directly attached to the substrate 221, thereby improving the heat transfer efficiency between components and improving the heat conduction efficiency of the heat sink 22.

Certainly, in practical applications, a plurality of second heat dissipation fins 214 parallel to the first side plate 212 may be further disposed on a side of the bottom plate 211 of the driver housing 21 facing the motor housing 11, and the second heat dissipation fins 214 are located in the second airflow channel, so that a part of heat on the driver housing 21 may be transferred through the second heat dissipation fins 214, and heat dissipation is performed by the second airflow channel, thereby further improving a heat dissipation effect.

Further, in order to ensure the sealing performance of the mounting cavity formed by the second side plate 213, the bottom plate 211 and the top cover, a sealant (e.g., a heat conductive silicone) disposed around the opening is disposed on the surface of the bottom plate 211 facing the side of the motor casing 11, that is, the sealant is disposed on the periphery of the substrate 221 of the heat dissipation portion 22 connected to the opening, so as to prevent the sealing performance of the mounting cavity from being affected by the existence of a connection gap.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
