Abstract
The utility model discloses a generator ventilation structure. The generator ventilation structure comprises a cooling fan, heat-radiating pipes, an explosion-proof casing and explosion-proof end covers. The cooling fan is installed on a rotor shaft of an explosion-proof generator and located in the explosion-proof casing, the explosion-proof end covers are installed on two ends of the explosion-proof generator, each explosion-proof end cover is provided with heat-radiating pipe installing holes, the heat-radiating pipes are aligned with and installed in the heat-radiating pipe installing holes, and the heat-radiating pipes are located outside the explosion-proof casing. The cooling fan is installed on the rotor shaft of the explosion-proof generator, and the heat-radiating pipes are disposed outside the two explosion-proof end covers, so, under the effect of the cooling fan on airflow in the generator, heat in the generator is radiated outside the generator through the heat-radiating pipes. In the condition that the sealing property of the explosion-proof generator is not destroyed, the heat in the generator is brought outside the generator through a clever design, and the heat-radiation problem of the explosion-proof generator is solved.
Description
Technical field
The utility model belongs to electrical generator fields, is specifically related to a kind of ventilating structure for magneto generator.
Background technology
Inflammable, explosive (colliery, the gas station, oil plant, flour cotton flax processing factory etc.) diesel generating set is often used in place, in order to keep the safety in production, the generating set that adopts must prevent the explosion-proof power generator group that spark produces, at present the scheme that adopts of explosion-proof power generator group is mainly to be sealed in explosion-proof housing motor is whole, thereby will easily produce pyrophoric structure and external isolation, prevents the accidents such as blast that produce due to spark.This structure can be effectively explosion-proof, but because generator is enclosed construction, and inner heat is difficult to distribute, and the temperature rise that causes sometimes generator is too high and burn out generator.
The utility model content
In order to overcome the deficiency in background technology, reach the purpose of explosion-proof power generator good heat radiating, the utility model provides a kind of ventilating structure for magneto generator.
In order to realize the foregoing invention purpose, the technical solution of the utility model is as follows:
A kind of ventilating structure for magneto generator, comprise cooling fan, radiating tube, explosion-proof housing, explosion-proof end cover, it is characterized in that: described cooling fan is arranged on the armature spindle of explosion-proof power generator, and be positioned at described explosion-proof housing, and at the two ends of explosion-proof power generator, explosion-proof end cover is installed, have the radiating tube installing hole on explosion-proof end cover, the installation of aliging with described radiating tube installing hole of described radiating tube, described radiating tube is positioned at the outside of described explosion-proof housing.
Be in specific embodiment of the utility model, described cooling fan is two, and all is arranged on armature spindle, and lays respectively at the two ends of explosion-proof power generator rotor.
Be in specific embodiment of the utility model between described explosion-proof end cover and described cooling fan, cavity is arranged.
Be that in specific embodiment of the utility model, the outer surface of described explosion-proof housing arranges bossed fin.
Because the utility model provides a kind of ventilating structure for magneto generator, by cooling fan being arranged on the armature spindle of explosion-proof power generator, then at the outer setting radiating tube of two explosion-proof end covers, air-flow in generator is under the effect of cooling fan, the process radiating tube is after the generator external cooling, suck again in generator from the other end, form successively circulation, thereby continuously the generator heat is taken to the outside of generator, in order to improve radiating effect, the fin that also is provided with projection in the explosion-proof housing outside of generator carries out auxiliary heat dissipation.The utility model is in the situation that destroy the closure of explosion-proof power generator, and to take outer motor to outside by designing dexterously heat with generator, solved the heat dissipation problem of explosion-proof power generator.

Fig. 1 is schematic diagram of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, be elaborated below in conjunction with legend.
As shown in Figure 1, a kind of ventilating structure for magneto generator comprises cooling fan 5, radiating tube 6, explosion-proof housing 2, explosion-proof end cover 4, wherein cooling fan 5 is arranged on the armature spindle 1 of explosion-proof power generator, and is positioned at explosion-proof housing 2, at the two ends of explosion-proof power generator, explosion-proof end cover 4 is installed, have the radiating tube installing hole on explosion-proof end cover, radiating tube 6 installation of aliging with the radiating tube installing hole, radiating tube 6 is positioned at the outside of explosion-proof housing 2.
Cooling fan 5 can arrange two, and all is arranged on armature spindle 1, and lays respectively at the two ends of explosion-proof power generator rotor 3.
Between explosion-proof end cover 4 and cooling fan 5, cavity 7 is arranged.
The outer surface of explosion-proof housing 2 arranges bossed fin 8.
The quantity of radiating tube 6 is the 4-8 root.
the utility model is by being arranged on cooling fan 5 on the armature spindle 1 of explosion-proof power generator, then at the outer setting radiating tube 6 of two explosion-proof end covers, air-flow in generator is under the effect of cooling fan 5, pass through successively the gap between explosion-proof power generator stator and explosion-proof power generator rotor 3, the radiating tube installing hole of explosion-proof end cover, radiating tube 6, cooling fan 5 forms circulation canal, gas process radiating tube 6 in the explosion-proof power generator chamber is after the generator external cooling, suck again in generator cavity from the other end, form successively circulation, thereby continuously the generator heat is taken to the outside of generator.In order to improve radiating effect, the fin that also is provided with projection in the explosion-proof housing outside of generator carries out auxiliary heat dissipation.The utility model is in the situation that destroy the closure of explosion-proof power generator, and to take outer motor to outside by designing dexterously heat with generator, solved seal and the heat dissipation problem of explosion-proof power generator.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
