Abstract

The utility model relates to a motor heat radiating device, particularly a device which can enhance the speed of heat radiation of the inner part when a motor runs. Primarily, the problem that the insufficiency of the heat radiation effect of the existing motor causes inner components of the motor to be destroyed by overheating is solved. A ventilating blower is arranged at the outer part of the motor, and outer cold air which is pumped by the ventilating blower is led in the inner space of the motor from a wind guiding mouth which is arranged on an outer casing of the motor, so the temperature of the inner components of the motor is reduced. Hot air in the inner space is exhausted out of the motor by an exhaust fan which is arranged at one end of the motor in order to increase the convection speed of the hot air in the inner space of the motor, and then the improved efficiency of rapid heat radiation can be achieved.

Description

Motor heat sink

Technical field

The utility model relates to a kind of motor heat sink, the particularly a kind of motor heat sink that can strengthen its internal heat dissipating speed when motor running.

Background technology

See also shown in Figure 1, existing motor 1 its shell 11 medial surfaces are installed with two symmetrical stators 12, the center is pivoted with a rotor 13, its radiating mode is that (or two ends) outside is equiped with a ventilating fan 14 in the one end, during with motor 1 running within it the hot-air that produced of portion space 15 discharge by described ventilating fan 14, described ventilating fan 14 is ends that are installed in described rotor 13 its axles 131, its rotating speed is synchronous with described rotor 13, so it is fast that its radiating rate is looked the rotating speed of described rotor 13, slowly determine, when its rotating speed is slow, the rotating speed of ventilating fan 14 is also slow, the radiating effect deficiency that it provided can't in time be discharged the hot-air that inner space 15 is produced, and is trapped in the described inner space 15, its temperature is constantly raise, and the internal structure that causes motor at last is because of the overheated fault person of damage.

Summary of the invention

The purpose of this utility model is to provide a kind of hot-air that is produced can be fast with motor running the time to discharge outside motor heat sink.

For achieving the above object, the technical solution adopted in the utility model is: a kind of motor heat sink, has a motor, described motor has a shell, its medial surface is installed with two symmetrical stators, be pivoted with a rotor in the center, be formed with an inner space between described stator and described rotor, described rotor has an axle, the one end is installed with a ventilating fan, it mainly is that shell at a motor digs and is provided with an air guide hole, be equiped with an air-supply arrangement in the connection of the outside of described air guide hole, the inside of described air-supply arrangement has a fan motor, the one end has an air inlet, the other end has an air outlet, described air outlet is to be communicated with described air guide hole, it is that inner space with motor connects, the cool exterior air of thus described air-supply arrangement being pumped imports the inner space of motor, to reduce the temperature of motor internal structure, by the set ventilating fan of motor one end the hot-air of inner space is discharged the motor outside again, improve the hot-air convection speed of its inner space thus, reach the progressive benefit of quick heat radiating.

Description of reference numerals

Prior art: 1 motor; 11 shells; 12 stators; 13 rotors; 131 axles; 14 ventilating fans; 15 inner spaces.

The utility model: 2 motors; 21 shells; 211 air guide holes; 22 stators; 23 rotors; 231 axles; 24 inner spaces; 3 ventilating fans; 4 air-supply arrangements; 41 air inlets; 42 air outlets; 43 fan motors.

Embodiment

See also Fig. 2, Fig. 3 and shown in Figure 4, motor 2 of the present utility model has a shell 21, its medial surface is installed with two symmetrical stators 22, be pivoted with a rotor 23 in the center, make 23 of described stator 22 and described rotors form an inner space 24, described rotor 23 is to have an axle 231, and the one end is installed with a ventilating fan 3, it is characterized in that:

Shell 21 1 lateral margins of described motor 2 dig and are provided with an air guide hole 211, it is the interval that is positioned at two symmetrical stators 22, can be for connecting described inner space 24, upper outer connection at described air guide hole 211 is equiped with an air-supply arrangement 4, one end of described air-supply arrangement 4 has an air inlet 41, the other end has an air outlet 42, and inside is provided with a fan motor 43, makes described air outlet 42 be communicated with described air guide hole 211.

Structure as above, when motor 2 runnings, described fan motor 43 can be pumped the cold air of outside to air-supply arrangement 4 inside by air inlet 41, enter inner space 24 from air outlet 42 via air guide hole 211, to reduce the temperature of motor 2 internal structure, the ventilating fan 3 that is set firmly via axle 231 1 ends is discharged outside (as shown in Figure 4 and Figure 5) with high temperature and the mixed hot-air of cold air that motor 2 runnings are produced again; When the rotating speed of motor 2 is slow, because described blowing fan 4 still continuously provides outside cold air to enter inner space 24, has strengthened the convection velocity of hot and cold air, improves the efficient of heat radiation, so can effectively reach the temperature that reduces motor, prevent that internal structure from damaging because of overheated.
