Cooling device of high-voltage asynchronous motor

The invention discloses a cooling device of a high-voltage asynchronous motor. The device comprises a base, a first connecting pipeline, a backflow pipeline and a cover frame, the first connecting pipeline is connected between the tops of water passing channels in a penetrating mode. The backflow pipeline and the first connecting pipeline are fixed to the front side and the rear side of a branch water pipe set through pipe hoops correspondingly. A cooling fan is arranged under the branch water pipe set, an electric water inlet valve and an electric water outlet valve are fixed to the upper side and the lower side of the front end face of the water storage tank in a penetrating mode correspondingly, the second connecting pipeline penetrates through the left side and the right side of the water storage tank to be connected with the outer side of the cooling machine, and the cover frame is arranged on the outer sides of a high-voltage asynchronous motor body and a cooling machine. According to the high-voltage a
