Problems solved by technology

This structure cools the motor through liquid cooling and air cooling, but both the liquid pump and the motor fan need to be equipped with independent power sources to provide working power, the structure is complex, and because multiple devices need to be driven, the energy consumption is large and the synchronization is poor. , the large number of parts also leads to troublesome installation, high damage rate and short service life, therefore, it is necessary to make further improvements

[0043] see Figure 13 , the air-oil mixed cooling system of the temperature-controlled motor and the controller of this embodiment is different from the first embodiment in that: the motor liquid cooling chamber b and the control liquid cooling chamber e are connected in series, that is, the liquid storage chamber c. The control liquid cooling chamber e and the motor liquid cooling chamber b are sequentially closed and connected in series. In order to improve the heat dissipation effect of the cooling liquid, a radiator may be arranged between the chambers to rapidly cool the cooling liquid.
