Water-air composite cooling motor structure and new energy automobile applying same

The invention discloses a water-air composite cooling motor structure, which performs air cooling on a rotor and a winding through an air circulation loop formed by a vent hole, a first vent hole, a second vent hole, a base cavity, a first motor inner cavity and a second motor inner cavity, and performs heat exchange through cooling liquid in a cooling liquid flow channel to cool air in the air circulation loop, therefore, air in the air circulation loop can cool the rotor and the winding all the time, the rotor and the winding are effectively cooled, motor faults caused by too high temperature of the rotor and the winding are prevented, and the service life of the motor rotor is effectively prolonged. The invention further discloses a new energy automobile applying the water-gas composite cooling motor structure. 本发明公开了一种水气复合冷却电机结构，通过通风孔、第一通气孔、第二通气孔、机座空腔、第一电机内腔和第二电机内腔形成的空气循环回路，对转子和绕组进行风冷，并通过冷却液流道中的冷却液进行换热对空气循环回路中的空气降温，使得空气循环回路中的空气能够一直对转子和绕组进行风冷，有效对转子和绕组进行降温，防止转子和绕组温度过高造成电机故障，有效延长电机转子的使用寿命。本发明还公开了一种应用上述水气复合冷却
