A liquid cooled motor enclosure includes a fluid sealed space adapted to contain a coolant fluid. A motor is disposed inside the enclosure, and the motor is thermally coupled to an inside portion of the enclosure. An inlet manifold and an outlet manifold are positioned at opposite axial ends of the enclosure. The cross-sectional areas of the inlet manifold and the outlet manifold are sized and configured to provide a substantially uniform flow of coolant around the entire circumference of the enclosure and/or such that coolant flowing in the space from the inlet manifold toward the outlet manifold is substantially axial. A plurality of lobes extend in the space to increase the surface area in contact with the coolant fluid and increase turbulence in the coolant fluid flowing in the space to increase heat transfer from the horse to the inner shell and from the inner shell to the coolant fluid.

    一种液体冷却式马达封围件,该液体冷却式马达封围件包括适于容纳冷却剂流体的流体密封空间。在封围件内部布置有马达,并且该马达热联接至封围件的内侧部。在封围件的相反的轴向端部处定位有入口歧管和出口歧管。入口歧管和出口歧管的横截面积被定大小和构造成围绕封围件的整个圆周提供大致均匀的冷却剂流并且/或者使得在该空间中从入口歧管朝向出口歧管流动的冷却剂是大致轴向的。在空间中延伸有多个凸起部,以增加与冷却剂流体接触的表面面积并且增加在空间中流动的冷却剂流体中的湍流,从而增加从马达到内壳以及从内壳到冷却剂流体的热传递。
