Abstract
The utility model discloses a generator comprising a casing, a rotating shaft in transmission connection in the casing, a fan fixedly connected to one end of the rotating shaft, and a plurality of heat radiation air channels axially arranged on the casing. With the heat radiation air channels arranged on the casing, natural wind enters into the heat radiation air channels through air inlets under the action of the fan, is exhausted from air outlets and takes away heat generated by a motor. The heat radiation air channels provide the stator and the rotor of the motor with a relatively open environment, thereby substantially improving heat radiation efficiency and prolonging the service lifetime of the motor.
Description
Technical field
The utility model relates to a kind of generator, relates in particular to a kind of generator with high cooling efficiency.
Background technology
Generator can produce huge heat in the long-time running process, if untimely these heats are derived will burn out coil, reduce the useful life of generator.Therefore, heat radiation is the extremely important factor that generator need be considered, known generator generally adopts natural wind cooling mode, if the unbalanced generator local temperature that will make of natural draft heat radiation raises, influences generator useful life.When generator was worked, the generator amature rotation drove the fan rotation by rotating shaft, and the wind that fan is discharged is discharged generator through the louvre of rear end cap, and the rotor of generator and stator are in the middle of the environment of relative closure, are unfavorable for the heat radiation of generator.
Summary of the invention
Problem to be solved in the utility model is for overcoming above-mentioned technological deficiency, providing a kind of radiating efficiency height, the generator of long service life.
In order to address the above problem, the utility model by the following technical solutions: a kind of generator, comprise casing, be connected with rotating shaft in the described casing, an end of described rotating shaft is fixedly connected with fan, described casing is provided with several heat dissipation wind channels that axially arranges.
Below be further improvement of the utility model:
The quantity of described heat dissipation wind channel is respectively three.
Further improve:
Described heat dissipation wind channel along the circumferential direction evenly is arranged on the casing.
Further improve:
Described heat dissipation wind channel comprises air inlet, air outlet, and the air inlet of described heat dissipation wind channel is located on the casing near on the end face of fan one end, and the air outlet of described heat dissipation wind channel is located on the end face of the casing other end.
The utility model adopts such scheme, is provided with heat dissipation wind channel at casing, and natural wind enters heat dissipation wind channel through air inlet under the effect of fan, discharges and the heat that motor produces is taken away through air outlet; Because the stator that is arranged so that motor of heat dissipation wind channel is in the relative open environment with rotor, has improved radiating efficiency greatly, has improved the useful life of motor.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Accompanying drawing 3 is the right view of accompanying drawing 1.
Among the figure: the 1-casing; The 2-rotating shaft; The 3-fan; The 4-heat dissipation wind channel; The 401-air inlet; The 402-air outlet.
Embodiment
Embodiment, as Fig. 1, Fig. 2, shown in Figure 3, a kind of generator, comprise casing 1, be connected with rotating shaft 2 in the described casing 1, an end of described rotating shaft 2 is fixedly connected with fan 3, described casing 1 is provided with several heat dissipation wind channels 4 that axially arranges, described heat dissipation wind channel 4 comprises air inlet 401, air outlet 402, and described air inlet 401 is located on the casing 1 near on the end face of fan 3 one ends, and described air outlet 402 is located on the end face of casing 1 other end.
The quantity of described heat dissipation wind channel 4 is respectively three.
Described heat dissipation wind channel 4 along the circumferential direction evenly is arranged on the casing 1.
During work, fan 7 rotates, natural wind enters heat dissipation wind channel 4 through air inlet 401 under the effect of fan 7, the heat that stator and rotor produce in air outlet 402 is discharged motor is taken away, make the stator of motor be in the relative open environment with rotor, improve radiating efficiency greatly, improved the useful life of motor.
The quantity of above-mentioned heat dissipation wind channel 4 can be four, five or other quantity, and the quantity that is not limited to the described heat dissipation wind channel 4 of above-described embodiment is three, but with easy to process and to reach best radiating effect be prerequisite.
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and everyly utilizes this design that the utility model is carried out unsubstantiality to change, all belong to the behavior of invading the utility model protection range.
