And good effect of heat exchange.
The utility model in order to solve its technical problem used by technical scheme be：A kind of fluid-cooled electrical machine cooling system,
Include the stator core of cylinder, several through holes parallel with its axis direction are interval with the stator core, it is each
Hollow tube is equipped with the through hole, the both ends of the hollow tube are extended respectively to outside the end face of the stator core；It is described fixed
Fixed cover is provided with pressing plate respectively in sub both ends of the surface unshakable in one's determination, and the pressing plate corresponds to each hollow tube and is provided with positioning hole, the pressing plate
Outer face on correspond to and be communicated with groove at odd number positioning hole.
As further improvement of the utility model, it is communicated with the outer face of the pressing plate at corresponding three positioning holes
Groove.
As further improvement of the utility model, it is communicated with the outer face of the pressing plate at corresponding five positioning holes
Groove.
As further improvement of the utility model, positioning spiral shell is provided with the positioning hole of the connectivity slot center
Bolt is so that the hollow tube to be fixedly connected with pressing plate.
