Connected with the inner chamber interlayer I of disk body I, form cooling water channel I；The drive end bearing bracket upper water-out joint I and water supply connector on housing exterior walls
II passes through pipeline connection；One group of rib of the same circumferentially spaced about storing of housing barrel bore area, rib length and housing axle
Line direction is identical, and rib inner surface is engaged with stator outer wall；It is theed improvement is that：Outside the disk body I in the left side of flange I
Some through holes I are provided between wall and the right side of disk body I；The through hole I does not connect with the inner chamber interlayer I of disk body I, forms cooling air channel
Ⅰ；Wind scooper is axially connected on the rear end cap inner side end；The wind scooper is the streamlined truncated cone structure in longitudinal section
Part, larger diameter end is towards the right side, and smaller diameter end is towards a left side.
In said structure, the rib quantity that the housing barrel bore area is provided with is the odd number within 3~11.
In said structure, the water supply connector I, water out adapter I are separately positioned on the central axis both sides of disk body I；It is described enter
Water swivel II, water out adapter II are separately positioned on casing center axis both sides, and water out adapter II is arranged on the right side of the outer wall of disk body I.
The present invention compared with prior art, has the positive effect that：
1st, the cooling air channel I on drive end bearing bracket forms the axial cooling air channel for running through motor inner chamber, larger diameter end court with wind scooper
Right truncated cone wind scooper, preferable air draught effect being formed, axial cooling air channel forms Compound cooling together with water channel cooling,
Significantly improve and drive heat drop temp effect.
2nd, the rib quantity that housing barrel bore area is provided with is the odd number within 3~11, in housing barrel endoporus table
Face forms odd number ventilating duct, forms irregular turbulent flow cooling wind, further improves and drive heat drop temp effect.
3rd, water supply connector I, water out adapter I are separately positioned on the central axis both sides of disk body I；Water supply connector II, water out adapter
II is separately positioned on casing center axis both sides, and water out adapter II is arranged on the right side of the outer wall of disk body I, so, dramatically increases water channel
The path of cooling, further improve and drive heat drop temp effect.
