Abstract
The utility model relates to a motor cooling technology and discloses a ventilation structure of an air-air cooler used for a motor. The ventilation structure of the air-air cooler used for the motor comprises a cuboid air-air cooler. A top of the cooler is provided with a centrifugal blower fan. Wind-guiding plates which are connected with an upper top cover and an inner side surface are arranged on two right angles which are formed by the upper top cover of the air-air cooler and the inner side surface, wherein the inner side surface is axially vertical to the motor. An eddy current and wind pressure losses can be reduced. A heat dissipation effect of the motor is strengthened and noises are reduced.
Description
Technical field
The utility model relates to the motor cooling technology, particularly a kind of aeration structure of hollow cooler for motor.
Background technology
At present, the interior wind of the hollow cooler that conventional motors is used cooling mainly by the centrifugal fan at cooler top, that the hot-air in motor is cooling by radiating tube after axially entering from blower fan, through the radially discharge of receded disk impeller from blower fan, enter cooling water pipe through the right angle of subcooler upper cover plate and medial surface formation again, the eddy current that this right angle forms causes larger air loss, affect the radiating effect of motor, and noise is large.
Summary of the invention
The purpose of this utility model is to provide a kind of aeration structure of hollow cooler for motor, is provided with wind deflector at the place, right angle of cooler upper cover plate and medial surface formation, reduces eddy current and air loss, strengthens the radiating effect of motor, and reduces noise.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of aeration structure of hollow cooler for motor, the hollow cooler that comprises cuboid, the top of hollow cooler is provided with centrifugal fan, it is characterized in that, the upper top cover of described hollow cooler be provided with respectively to the place, two right angles that vertical medial surface forms the wind deflector that is connected upper top cover and medial surface with motor shaft.
Characteristics of the present utility model and further the improvement are:
Described wind deflector is dull and stereotyped.
Described wind deflector is arc.The characteristics of the technical program and further improving are: described arc is the circular arc plate, and respectively with the upper top cover of described hollow cooler with tangent to vertical medial surface with motor shaft.
The aeration structure of hollow cooler for motor of the present utility model, the hollow cooler that comprises cuboid, the top of cooler is provided with centrifugal fan, the upper top cover of described hollow cooler be provided with respectively to the place, two right angles that vertical medial surface forms the wind deflector that is connected upper top cover and medial surface with motor shaft, can reduce eddy current and air loss, strengthen the radiating effect of motor, and reduce noise.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation that conventional motors is used the aeration structure of hollow cooler;
Fig. 2 is the structural representation of the aeration structure of hollow cooler for motor of the present utility model.
In figure: 1, centrifugal fan; 2, hollow cooler; 3, upper cover plate; 4, medial surface; 5, wind deflector; 6, interior wind air outlet; 7, interior wind air inlet.
Embodiment
With reference to Fig. 1, be the structural representation of conventional motors with the aeration structure of hollow cooler.Interior hot blast in motor is gone out from interior wind air outlet 6, axially entering from centrifugal fan 1 after once cooling by the radiating tube in hollow cooler 2, impeller radially going out from blower fan through centrifugal fan 1, enter cooling water pipe through the upper cover plate 3 of hollow cooler 2 and the right angle of medial surface 4 formation again, then by interior wind air inlet 7, cooled air is sent into motor, reach the effect of cooling motor.But the eddy current that this right angle forms causes larger air loss, affect the radiating effect of motor, and noise is large.
With reference to Fig. 2, be the structural representation of the aeration structure of hollow cooler for motor of the present utility model.The upper top cover 3 of hollow cooler 2 be provided with respectively to the place, two right angles that vertical medial surface 4 forms the wind deflector 5 that is connected upper top cover 3 and medial surface 4 with motor shaft.In the present embodiment, wind deflector 5 is circular arc, and tangent with upper cover plate 3 and interior plate 4.Wind deflector 5 can become the wind direction of right-angled bend along the direction of wind deflector 5, reduces the right angle eddy current, reduces air loss, strengthens the radiating effect of motor.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that do not break away from the scope that the utility model claim is protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
Claims (4)
1. the aeration structure of a hollow cooler for motor, the hollow cooler that comprises cuboid, the top of hollow cooler is provided with centrifugal fan, it is characterized in that, the upper top cover of described hollow cooler be provided with respectively to the place, two right angles that vertical medial surface forms the wind deflector that is connected upper top cover and medial surface with motor shaft.
2. the aeration structure of a kind of hollow cooler for motor according to claim 1, is characterized in that, described wind deflector is dull and stereotyped.
