The utility model provides a direct current that radiating effect is good has brush motor aims at solving the poor problem of radiating effect.

The utility model discloses a realize like this, a direct current that the radiating effect is good has brush motor, its characterized in that: the air conditioner comprises a base, a cylinder, an air outlet screen plate, an air inlet screen plate, a motor output shaft, a motor main body, a ventilation opening and a fan; the barrel is installed in the base upper end, and the air-out otter board is installed at the barrel right-hand member, and the otter board that entries is installed at the barrel left end, and motor output shaft wears out from the otter board center that entries, and motor main part is installed inside the barrel, and motor main part both ends are opened there is the vent, and the fan is established at the inside left end of barrel, fan and motor output shaft connection.

Further, the length of the fan is greater than the diameter of the motor body.

Furthermore, twenty mounting grooves which are parallel to each other are formed in the inner surface of the cylinder body at equal intervals, twenty partition plates which are parallel to each other are welded outside the motor main body at equal intervals, and one third of the partition plates are embedded in the mounting grooves.

Furthermore, the lower end of each partition plate is provided with five heat dissipation holes.

Furthermore, the twenty partition plates and the twenty mounting grooves are coaxial with the output shaft of the motor.

Further, the barrel is fixed to the base by a hexagonal bolt.

About implementing the utility model discloses a beneficial technological effect does: the rotating fan can take away heat in the motor main body and effectively cool the shell of the motor main body, so that double cooling is realized, and the cooling effect is good; because the length of the fan is larger than the diameter of the motor main body, the fan can effectively improve the air flow strength in the space between the motor main body and the cylinder; the inner surface of the cylinder body is provided with twenty mounting grooves which are parallel to each other and are at equal intervals, twenty partition plates which are parallel to each other are welded at equal intervals outside the motor main body, and one third of the partition plates are embedded in the mounting grooves, so that air flow flows along gaps between the adjacent partition plates; because the lower end of each clapboard is provided with five heat dissipation holes, the clapboard can be prevented from being too thick and difficult to dissipate heat; the twenty partition plates, the twenty mounting grooves and the motor output shaft are coaxial to form almost ordered airflow, so that heat dissipation is facilitated; the cylinder is fixed on the base through the hexagon bolts, so that the cylinder is convenient to detach and install.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the motor body 6 and the fan 11 are conventional technologies and are common general knowledge of those skilled in the art, and are not described herein again.

Referring to fig. 1-4, the utility model relates to a direct current that radiating effect is good has brush motor, its characterized in that: the air conditioner comprises a base 1, a cylinder 2, an air outlet screen plate 3, an air inlet screen plate 4, a motor output shaft 5, a motor main body 6, a ventilation opening 10 and a fan 11; the barrel 2 is installed at the upper end of the base 1, the air outlet screen plate 3 is installed at the right end of the barrel 2, the air inlet screen plate 4 is installed at the left end of the barrel 2, the motor output shaft 5 penetrates out of the center of the air inlet screen plate, the motor main body 6 is installed inside the barrel 2, the ventilation openings 10 are formed in the two ends of the motor main body 6, the fan 11 is arranged at the left end inside the barrel 2, and the fan 11 is connected with the motor output shaft 5.

The length of the fan 11 is larger than the diameter of the motor main body 6, so that the fan 11 can effectively improve the air flow intensity in the space between the motor main body 6 and the cylinder 2.

Twenty mounting grooves 9 which are parallel to each other and are at equal intervals are formed in the inner surface of the cylinder body 2, twenty partition plates 7 which are parallel to each other are welded to the outer portion of the motor main body 6 at equal intervals, and one third of the partition plates 7 are embedded in the mounting grooves 9, so that air flow flows along gaps between the adjacent partition plates 7.
