[0001] The present application relates to the technical field of driving heat dissipation, in particular to a split type gas-liquid internal circulation active heat dissipation driving device. BACKGROUND

[0002] Driving power refers to the force or energy that can make an object move or change. Such as mechanical force, electricity, heat, etc. In physics, power usually refers to the force on an object, which can change the motion state of the object. In some devices, power is essential, such as: the power device of the propeller, the wheel hub motor, the unmanned aerial vehicle motor, the water pump, etc. It is realized by the principle of motor output to generate power.

[0008] Compared with the existing driving device, the application realizes efficient heat dissipation of the stator assembly through the gas-liquid internal circulation mode. When the gas-liquid enters the rear cavity from the gas-liquid inlet, passes through the rear cavity and enters the front cavity, and then is guided out from the gas-liquid outlet, the heat generated by the stator assembly can be effectively taken away, thereby realizing efficient heat dissipation. The stator outer support and the stator inner support are connected together through the outer connecting table, the inner connecting table and the rear cavity and other components, forming a stable support structure, ensuring the stability and reliability of the whole device.
