Abstract
The utility model discloses a kind of motor case, described shell is annulus plate-like, and it comprises diapire, and bottom wall edge extends the annulus wall with certain altitude, it is characterized in that being provided with through hole in the middle part of described diapire, between described through hole and diapire outward flange, be provided with multiple louvre.The utility model can reduce motor production and processing operation, reduces fan blade parts, reduces small product size, reduce costs, good heat dissipation effect, structure is simple, when market product (as fan, air purifier) can be made to use, or save space, can reduce costs equally.Be provided with multiple louvre at diapire, motor rotor inner air convection frame can be made fast, and radiating rate is accelerated, and temperature rise reduces.
Description
[technical field]
The utility model relates to a kind of motor case.
[background technology]
Existing low pressure 24V DC Brushless Motor power comparatively large (more than 30W) in use, raises to control motor temperature, is generally on motor rotor axle, install the little fan blade of heat radiation, armature spindle rotates, also just drive fan blade to rotate, after producing wind, air is flowed, motor is lowered the temperature.This shortcoming of installing the motor of the little fan blade of heat radiation has: 1, install the little fan blade material of heat radiation and operation increase, add motor cost; 2, motor bulk shape size increases, and requires that the part dimension coordinated with its installation also needs to increase equally, finally causes the cost of finished product (as fan, air purifier) to increase.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and reduces motor production and processing operation, reduce fan blade parts, reduce small product size, reduce costs, good heat dissipation effect, the simple motor case of structure.
The purpose of this utility model is achieved in that
A kind of motor case, described shell is annulus plate-like, and it comprises diapire, and bottom wall edge extends the annulus wall with certain altitude, it is characterized in that being provided with through hole in the middle part of described diapire, is provided with multiple louvre between described through hole and diapire outward flange.
A kind of motor case as above, is characterized in that described multiple louvres are centered by through hole, being arranged on diapire of fan-shaped array.
A kind of motor case as above, is characterized in that the inner side of described louvre is little U-shaped hole, and the outside of louvre is large U-shaped hole, and little U-shaped hole is connected with the transition of large U-shaped hole circle arc and connects.
The utility model can reduce motor production and processing operation, reduces fan blade parts, reduces small product size, reduce costs, good heat dissipation effect, structure is simple, when market product (as fan, air purifier) can be made to use, or save space, can reduce costs equally.Be provided with multiple louvre at diapire, motor rotor inner air convection frame can be made fast, and radiating rate is accelerated, and temperature rise reduces.
[accompanying drawing explanation]
Fig. 1 is structure chart of the present utility model;
Fig. 2 is vertical view of the present utility model.
[embodiment]
A kind of motor case, described shell 1 is annulus plate-like, and it comprises diapire 2, and diapire 2 edge extends the annulus wall 3 with certain altitude, is provided with through hole 21, is provided with multiple louvre 5 between described through hole 21 and diapire outward flange in the middle part of described diapire 2.Louvre 5 can make motor rotor inner air convection frame fast, and radiating rate is accelerated, and temperature rise reduces.
Multiple louvre 5 centered by through hole 21, being arranged on diapire of fan-shaped array.
The inner side of louvre 5 is little U-shaped hole 51, the outside of louvre 5 is large U-shaped hole 52, little U-shaped hole 51 is connected with large U-shaped hole 52 arc transition and connects, and that is little U-shaped hole 51 communicates with large U-shaped hole 52, just louvre 5 is designed to the structure that large inner side, outside is little.Owing to being that the air-flow of the inner ring part at axle center is less with rotating shaft in housing, being that the air-flow of the outer ring part at axle center is comparatively large with rotating shaft in housing, so need the inner side of louvre 5 to be designed to little U-shaped hole 51, the outside of louvre 5 being designed to large U-shaped hole 52.
