Abstract
A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.
Description
- The present invention relates to a motor and, more particularly, to a motor with a heat dissipation structure capable of restraining temperature therein, wherein the motor is provided with a hollow hood at its housing for collecting the air current generated by a cooling fan provided at a rotating shaft of the motor, wherein one portion of the hollow hood is located above at least one upstream through hole of the motor's housing, so that the air current can quickly enter the housing via the upstream through hole to dissipate heat therein, and thus the performance and service life of the motor can be increased.
- Today, motors are widely used in industry for providing mechanical power. When a motor, irrespective of lower or high power, is running, the rotor assembly (including an armature core formed by an iron core wound with enameled wire, a commutator, a brush unit, etc.) and the magnets in the motor's housing will generate heat and thus cause a temperature rise. In particular, the heat accumulated in the motor's housing may cause the brush unit to contain more carbon deposits, thus affecting the electrical circuit of the motor. Besides, high temperature resulting from the armature core may reduce the magnetic intensity of the magnets used in the motor. Thus, the performance of the motor will be gradually reduced.
- Currently, emergency repair kits, which are commonly used in daily life, employ a low-power motor to drive a compressor unit therein for repairing punctured tires. However, in some countries, the Traffic Act stipulates that, when a tire being punctured happens to a vehicle on a highway, the driver should repair the punctured tire within a specified period and should immediately drive away after the repair is completed to prevent rearward bump. Under these circumstances, for completing the repair as soon as possible, the motor of the compressor unit of an emergency repair kit should be operated at a higher speed. However, if the heat accumulated in the motor's housing cannot be quickly taken away, the performance of the motor will decrease. Even worse, the enameled wire of the armature core will probably be damaged to cause a short circuit, and thus the motor may burn out.
- For solving this problem, a motor is usually installed with a cooling fan at its output shaft. However, the airflow induced by the cooling fan can only flow along the outer surface of the motor's housing. Thus, the heat generated by the armature core, especially the enameled wire, in the motor is not easy to be taken away. The problem of a motor being subject to heat accumulation has not yet been overcome.
- One object of the present invention is to provide a motor with a heat dissipation structure, wherein the housing of the motor is provided with a hollow hood for collecting the air current generated by a cooling fan provided at a rotating shaft of the motor. The housing defines at least one upstream through hole and at least one downstream through hole. The hollow hood is mounted to the housing such that a head portion thereof is located above the upstream through hole. The air current can be effectively collected by the hollow hood to enter the housing via the upstream through hole and finally to go out of the housing via the downstream through hole, so that the heat generated by the rotor assembly in the housing can be quickly taken away. Thus, heat is not easy to accumulate in the housing, maximum power output of the motor can be achieved, and the performance and service life of the motor can be increased.
- Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

FIG. 2 shows a 3-dimensional view of the motor, which is viewed from a different angle thanFIG. 1 . -

FIG. 7 shows a sectional view of the motor taken along line C-C inFIG. 4 , wherein the air current generated by the cooling fan is demonstrated. - Since motors are commonly used devices, the principles of a motor's operation are not illustrated in the following paragraphs. However, basic elements of a motor will be described in this specification. Referring to
FIGS. 1 through 7 , a motor according to one embodiment of the present invention is shown, which includes acylindrical housing 1, in which a rotor assembly and twoopposite magnets 12 are provided. The rotor assembly includes a rotatingshaft 16, an armature core formed by aniron core 171 wound withenameled wire 172, and acommutator 173. The twoopposite magnets 12 are provided at an inner surface of thecylindrical housing 1. Thehousing 1 has a circumferential wall which terminates at a flat closure wall 101 (a front end of the motor). Theflat closure wall 101 is provided with a first bearing 11 at its center and defines a plurality of downstream throughholes 103 around the first bearing 11. A first end of the rotatingshaft 16 is mounted to the first bearing 11 (seeFIG. 2 ). The circumferential wall of thehousing 1 defines a plurality of upstream throughholes 10 for allowing outside air to enter thehousing 1. Asleeve 3, which is made of a magnetically permeable metal, is closely fitted around thecylindrical housing 1, so as to increase the performance of the motor. - A
cover 2 is provided with a second bearing 21 at its center and mounted to a rear end of thehousing 1 opposite to theflat closure wall 101. A second end of the rotatingshaft 16 of the rotor assembly is mounted at the second bearing 21 (seeFIG. 1 ). Acooling fan 4 is installed to the second end of the rotatingshaft 16 of the rotor assembly, near thecover 2. Thecover 2 defines a plurality ofair inlets housing 1 to dissipate heat therein. - A primary feature of the present invention is that a
hollow hood 5 is provided at a front portion of thecylindrical housing 1 near thecooling fan 4 for collecting the air current generated by thecooling fan 4. Thehollow hood 5 has aneck portion 51, ahead portion 52, and a gradually enlarged transitional portion between theneck portion 51 and thehead portion 52, wherein theneck portion 51 opens out at afirst opening 510 while thehead portion 52 opens out at a second opening 520 which is opposite to the first opening 510. Thehollow hood 5 is mounted to thecylindrical housing 1 such that theneck portion 51 is closely fitted around thecylindrical housing 1 while thehead portion 52 is located above the throughholes 10, thus defining an annular air-guidingchannel 6 therebetween which communicates with the throughholes 10, and forming anintercepting surface 7 at an inner surface of the gradually enlarged transitional portion of thehollowing hood 5. Thehollow hood 5 is a bell-shaped body, so that the annular air-guidingchannel 6 has a cross-sectional dimension which increases gradually as extending from the interceptingsurface 7 to the second opening 520 of thehollow hood 5. In this embodiment, as shown inFIG. 3 , thefirst opening 510 of thehollow hood 5 is a circular opening, which has a diameter of (Y); the second opening 520 of thehollow hood 5 is a circular opening, which has a diameter of (X); the gradually enlarged transitional portion of thehollow hood 5 generally has an internal diameter of (Z) at its interceptingsurface 7; wherein the relationship of X>Y and X>Z and Y=Z is fulfilled. Thehollow hood 5 can be mounted to thecylindrical housing 1 via thefirst opening 510, wherein theneck portion 51 of thehollow hood 5 is closed fitted around the front portion of thecylindrical housing 1; thehead portion 52 is located above thecylindrical housing 1 and the upstream throughholes 10 and thus is not in contact with thecylindrical housing 1. The annular air-guidingchannel 6 is defined between thehead portion 52 of thehollow hood 5 and thecylindrical housing 1, and the throughholes 10 are located between the interceptingsurface 7 and the second opening 520 of thehollow hood 5, so that the air current can pass through the annular air-guidingchannel 6 and the throughholes 10 to enter thecylindrical housing 1 to take away the heat generated therein. The interceptingsurface 7 of thehollow hood 5 can intercept the air current entering the annular air-guidingchannel 6 to facilitate it to pass through the throughholes 10 to enter thehousing 1. - In operation, as shown in
FIG. 5 , in addition to some of the air current generated by thecooling fan 4 being able to enter thehousing 1 via theair inlets cover 2, most of the air current generated by thecooling fan 4 can be collected by thehollow hood 5, wherein the interceptingsurface 7 can intercept or block the air current entering the annular air-guidingchannel 6, so that the air current can pass through the upstream throughholes 10 to enter thecylindrical housing 1 more easily. After the air current enters thecylindrical housing 1, the heat generated by thebrush unit 192, the commutator 173 (seeFIG. 6 ), and theiron core 171 wound with the enameled wire 172 (seeFIG. 7 ) can be taken away and finally the air current can flow out of thehousing 1 via the downstream throughholes 103, so that heat is not easy to accumulate in thehousing 1 and thus the service life of the motor can be increased. In addition, if the diameter of thecooling fan 4 is larger than that of the second opening 520 of thehollow hood 5, some of the air current generated by thecooling fan 4 may pass over thehollow hood 5 to flow along the outer surface of the circumferential wall of thecylindrical housing 1 and thesleeve 3 to cool down the housing 1 (seeFIG. 5 ). - As a summary, the
hollow hood 5 of the motor of the present invention can effectively collect the air current generated by thecooling fan 4, so that the air current can quickly enter thecylindrical housing 1 via the upstream throughholes 10 to dissipate the heat generated therein. As such, heat is not easy to accumulate in the housing and thus the performance and service life of the motor can be increased.
