Abstract
The utility model discloses a heat dissipating structure of an air blower. The heat dissipating structure comprises a shell, an impeller and a motor, the impeller and the motor are arranged inside the shell, the impeller comprises a center disc and blades fixed on the center disc, multiple square holes are formed in the center disc, the shell is formed by assembling a front shell and a rear shell, the rear shell comprises a rear base and a rear impeller containing portion, one side, away from the front shell, of a rear impeller protrudes outwards to form a motor containing portion, the motor is placed on the motor containing portion, multiple big openings used for heat dissipating are arranged on a shell of the motor, one side, away from a front cover, of the motor containing portion is provided with a square opening used for heat dissipating of the motor and extends to form a protecting cover corresponding to the square opening, and an air vent is formed between the protecting cover and the motor containing portion. By the heat dissipating structure, heat generated by the motor can be fully discharged out of the motor containing portion, temperature of the motor can be effectively lowered, and service life of the motor can be prolonged.
Description
Technical field
The utility model relates to the radiating structure of a kind of blower, particularly a kind of blower.
Background technique
Existing blower, its motor generally is mounted in the scaffold at shell rear, be that shell is what to separate with scaffold, this structure takes up room larger, the installation of motor is cumbersome, and after being arranged on scaffold by motor, also need scaffold is connected with the back cover of shell, therefore operating process is cumbersome and loaded down with trivial details, radiation hole is not set on scaffold in addition, although perhaps be provided with radiation hole, but the layout of radiation hole neither be quite reasonable, therefore the radiating effect of motor is also bad, and dust and other impurities easily falls into scaffold from radiation hole, will have influence on so the normal use of motor.
In addition, opening generally all is not set on the spider of impeller, when the wheel rotation of blower, it is more serious that the motor feels hot at the blower rear portion, and go out in the air channel that the wind of entering from the front portion of blower directly just arranges from blower drum, can not play cooling action to motor, so the heat dispersion of blower bad.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides the radiating structure of the blower in a kind of working life that can effectively extend motor.
The utility model solves the technological scheme that its technical problem adopts:
A kind of radiating structure of blower, comprise shell and be arranged on impeller and the motor of enclosure, described impeller comprises spider and is fixed on the blade on spider, described spider is provided with a plurality of square openings, described square opening circumferentially is uniformly distributed along spider, described shell is assembled by fore shell and back cover, back cover comprises rear base and rear impeller holding part, rear impeller holding part is protruded with the motor holding part away from a side direction of fore shell, described motor is placed on the motor holding part, the shell of described motor is provided with a plurality of large openings for heat radiation, the motor holding part is provided with for the square aperture of motor radiating and is extended with the safety cover corresponding with square aperture away from a side of front shroud, form relief opening between described safety cover and motor holding part.
In the utility model, between safety cover and motor holding part, also be provided with many stiffening ribs.
The beneficial effects of the utility model are: the spider of impeller of the present utility model is provided with a plurality of square openings, the wind of entering from the blower front portion can blow to motor from square opening, motor is played to cooling action, can reduce the temperature of motor, be conducive to the heat radiation of motor.In addition, also be provided with square aperture and safety cover on the motor holding part, between safety cover and motor holding part, be formed with relief opening, the heat that can make motor produce is fully discharged the motor holding part, can effectively reduce the temperature of motor and the working life of improving motor.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is exploded view of the present utility model;
Fig. 2 is the structural representation of back cover in the utility model.
Embodiment
As shown in Fig. 1 ~ Fig. 2, a kind of radiating structure of blower, comprise shell and be arranged on impeller 1 and the motor of enclosure, described impeller 1 comprises spider 2 and is fixed on the blade 3 on spider 2, described spider 2 is provided with a plurality of square openings 4, described square opening 4 circumferentially being uniformly distributed along spider 2, described shell is assembled by fore shell 5 and back cover 6, back cover 6 comprises rear base 7 and rear impeller holding part 8, rear impeller holding part 8 is protruded with motor holding part 9 away from a side direction of fore shell 5, described motor is placed on motor holding part 9, the shell of described motor is provided with a plurality of large openings 10 for heat radiation, motor holding part 9 is provided with for the square aperture of motor radiating and is extended with the safety cover corresponding with square aperture 11 away from a side of front shroud, form relief opening between described safety cover 11 and motor holding part 9, also be provided with many stiffening ribs between safety cover 11 and motor holding part 9.The spider 2 of impeller 1 of the present utility model is provided with a plurality of square openings 4, and the wind of entering from the blower front portion can blow to motor from square opening 4, and motor is played to cooling action, can reduce the temperature of motor, is conducive to the heat radiation of motor.In addition; also be provided with square aperture and safety cover 11 on motor holding part 9; be formed with relief opening between safety cover 11 and motor holding part 9, the heat that can make motor produce is fully discharged motor holding part 9, can effectively reduce the temperature of motor and the working life of improving motor.
The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
