Cooling fan device and cooling equipment with same

The invention discloses a cooling fan device. The cooling fan device includes a permanent magnet synchronous motor, an impeller and a control device; the permanent magnet synchronous motor includes anouter shell, annular stators which are stored and fixed in the outer shell, and rotors which are surrounded by the stators and output shafts which are coaxially connected to the rotors; a driving endof the output shaft extends out of the outer shell, and a motor is suitable for being fixed to a bridge frame of cooling equipment through the outer shell; the impeller is connected to the driving end of the output shaft; and the control device is electrically connected with the motor for controlling the running of the motor. The invention further discloses cooling equipment with the cooling fandevice. Compared with the prior art, the operating maintenance cost can be reduced and the running efficiency can be improved through the cooling fan device. 本发明公开了种冷却风机装置，其包括：永磁同步电机，包括：外壳、容纳并固定到所述外壳内的环形的定子、被所述定子环绕的转子、以及与所述转子同轴
