Driving device with good heat dissipation effect for numerical control machine tool

The invention discloses a driving device with the good heat dissipation effect for a numerical control machine tool. The driving device comprises a heat dissipation shell; a driving box is fixedly connected to the middle point of the bottom of the inner wall of the heat dissipation shell; a cooling box is fixedly connected to the middle point of the top of the heat dissipation shell; and a first cooling pipe is arranged at the bottom of the left side of the inner wall of the cooling box. According to the driving device, through mutual cooperation of the heat dissipation shell, the cooling box,the first cooling pipe, a second cooling pipe, a circulating pump, a water outlet pipe, a water inlet pipe, a third cooling pipe, fourth cooling pipes, fifth cooling pipes, a sixth cooling pipe, supporting columns, bottom plates, rotating motors, rotating rotary shafts, heat collecting plates, heat dissipation motors, heat dissipation rotary shafts, fixed blocks, heat dissipation blades, first heat dissipation openings a
