Description
Technical field
The utility model relates to technical field of motors, is specifically related to a kind of cooling device of motor.
Background technology
Existing low-power machine is mainly dispelled the heat by air-flow, at machine shaft, an aerofoil fan is installed, this aerofoil fan along with rotor turns thus formed want motor shaft to air-flow, by air-flow to motor radiating, existing structure apoplexy enters from fan housing, is axially cooled motor by aerofoil fan.The circulation of this structure wind is bad, be unfavorable for heat radiation.As the Chinese invention patent " a kind of motor ventilation structure of low noise and high heat dissipation " that the patent No. is CN200910025828.1, it comprises support, the radiating ribs be located on support, the wind collecting unit of motor end and the aerofoil fan that is arranged in motor, the half of described aerofoil fan is exposed outside wind collecting unit, and second half and wind collecting unit are overlapping.Described radiating ribs medium position is provided with concave configuration.During cooling, air is sucked from the air inlet of fan guard by aerofoil fan, enter support along support gap to cool, but the area of dissipation of this motor ventilation structure is little, the mobility of air-flow is inadequate, only movement inside is cooled, and the outer surface of movement can not get timely cooling, radiating effect is not very desirable.
Summary of the invention
Technical problem to be solved in the utility model provides for the above-mentioned state of the art that a kind of structure is simple, result of ventilating heat dissipation good, and the cooling device of motor cheap for manufacturing cost, effectively can improve the operating efficiency of motor.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cooling device of motor, comprise motor core, be arranged on aerofoil fan in motor core rotating shaft and fan housing, it is characterized in that: described fan housing is involutory to be set on aerofoil fan, the front end face of fan housing is provided with air inlet, fan housing sidepiece peripherally radial direction offer multiple air outlet.
As improvement, the front end of described motor core is provided with an end cap, and described aerofoil fan is installed in rotation on end cap and is connected and fixed with the rotating shaft through end cap.
As improvement, described end cap is round table-like, bottom the periphery of the round platform of described end cap, be provided with the annular edge edge be involutory with fan housing, described fan housing is involutory to be set on end cap, forms the wind guide tank of an annular between the sidepiece and the round platform edge of described end cap of described fan housing.
As improvement, described air outlet is side opening, and is arranged on the sidepiece of described fan housing with uniform intervals, and the opening direction of described air outlet is just in time relative with the rotation direction of described aerofoil fan.
Improve, described air inlet is arranged on the front end face center of described fan housing again, and the bore of described air inlet and the internal diameter of aerofoil fan match.
Further improvement, the flabellum shape of described aerofoil fan is in downward-sloping from inside to outside, and described fan housing forming the inwall matched with flabellum shape is the annular boss on inclined-plane.
Compared with prior art, the utility model has the advantage of: multiple air outlet is set at the sidepiece of fan housing, be distributed to uniformly in electric machine casing along air outlet by wind guide tank after such cooling air enters, substantially increase air permeability and area of dissipation.Not only structure is simple for the utility model, result of ventilating heat dissipation is good, and cheap for manufacturing cost, effectively can improve motor working efficiency.
