Abstract

A motor body 2 includes a stub 21 force-fitted in a center hole 31 of a housing 3, a fan 1 rotatably supported around the motor body 2, and fins 32 extending from the housing 3 to improve heat dissipation. A space 30 within the array of fins 32 receiver the motor body 2 and may receive the fan 1. Through holes (33c, Figs 7, 8) may be provided in the housing 3 further improving heat dissipation. One or more depressions (33d, Fig 9) may be provided on that face of the housing opposite the fins to facilitate heat dissipation when the housing closely contacts another object. <IMAGE>

Description

TITLE: MOTOR HAVING A HEAT DIS' The invention relates to a motor having a heat dissipation configuration.

typical motor such as the DC motor is shown in FIGS. 11 and 12 and comprises a fan A and a motor B disposed within a housing C which is made of plastic materials. the heat dissipation effect of the topical motor is bad.

The invention is intended to provide a motor which has a heat dissipation configuration for facilitating the heat dissipating effect of the motor.

FIG. 1 is an exploded view of a motor: FIG. 2 is a cross sectional view of the motor: FIG. 3 is a perspective view illustrating another embodiment of the housing of the motor: FIG. 4 is a cross sectional view taken along lines -4 of FIG. 3; FIG. 5 is a perspective view illustrating stlli another embodiment of the housing of the motor: FIG. 6 is a cross sectional view taken along lines 6-6 of FIG. 5: FIG. , is a perspective view illustrating a further embodiment of the housing of the motor: FIG. 8 is a front elevational view of the housing as shown in FIG. ;; FIG. 9 is a front view of another embodiment of the housing of the motor: FIG. 10 is a side view of still another embodiment of the housing of the motor: FIG. 11 is an exploded view of a typical motor; and FIG. 12 is a cross sectional view of the typical motor.

Referrina to FIGS. 1 and 2. a motor comprises a fan 1 and a motor body ' secured to a housing 3. the fan 1 is rotatably provided around the motor body 2.

the body 2 includes a stub 21 extended therefrom and forced into a hole 31 formed in the center portion of the housing 3 so as to secure the body 2 to the housing j, the housing 3 includes a space 30 formed in the center portion for receiving the body 2 and the fan 1.

the housing 3 further includes a plurality of fins 32 extended therefrom and arranged around the body and the fan so as to form the heat dissipating configuration.

it is to be noted that part of the fins 32 located behind the fan 1 has a smaller height and arranged such that the fins 32 will not contact with the fan 1, the other fins 32 located around the fan 1 may be provided to protect the fan 1 from contacting with other objects.

Referring next to FIGS. 3 and 4, the housing 3a also includes a hole 31a for engaging with the stub of the body, a space 30a for receiving part of the body and a number of fins 39a extended therefrom, in which the fins 35a hae a height smaller than that shown in FIG. 1 such that the fan is exposed.

Referring next to FIGS. 5 and 6 the housing 3b also includes a hole 31b for engaging with the stub of the body. a space 30b for receiving part of the body and a number of fins 32b extended therefrom.

Referring next to FIGS. 7 and S, the housing 3c also includes a hole 31c for engaging with the stub of the body. a space 30c formed within fins 32c for receiving part of the body. the housing 3c further includes a number of openings 3 3 c for further facilitating heat dissipation effect of the body.

Referring next to FIG. 9. the housing 3d also includes a piuralitv of fins 3"d, the housing further includes at least one depression 33d formed in the bottom portion opposite to the fins 32d, the depressions 33d facilitate the heat dissipation effect when the housing 34 closely contacts with other object.

As shown in FIG. 10, the housing 3e mav include a plurality of openings 33 e formed therein and may further include at least one notch 33e formed in the outer peripheral portion thereof for engaging with other protrusions or the like so as to solidly secure the housing to other objects.

Accordingly, the motor includes a heat dissipation configuration for facilitating the heat dissipation effect of the motor.

Claims

CLAIMS:

1. A motor comprising a body including a stub extended therefrom, a fan rotatably provided around said body, and a housing including a hole formed therein for receiving said stub of said body, a plurality of fins extended from said housing, and a space formed in said fins for receiving said body and said fan, said fins being located around said fan for protecting said fan.

2. A motor according to claim 1, wherein said housing further includes a plurality of openings for facilitating heat dissipating effect.

3. A motor according to claim 1, wherein said housing includes at least one depression formed in the bottom portion thereof.

4. A motor according to claim 1, wherein said housing further includes at least one notch formed in an outer peripheral portion thereof.

5. A housing for a motor, the housing comprising means for receiving a portion of the motor and heat dissipation means disposed at least around said means for receiving and comprising a plurality of projections and/or depressions formed in or on said housing.

6. A motor substantially as herein described with reference to FIGS. l to 10.
