Housing with finned heat sink and orientation of the fins at a non-zero angle of attack
By setting non-zero angle of attack and tilt angle on the fins of the motor heat sink, the cooling air is circulated in a spiral shape, which solves the problem of large motor size and heavy weight caused by the fin design in the prior art, and achieves more efficient cooling effect and lighter motor design.
