Auxiliary air-cooled generator

Abstract

The invention discloses a power generator with an auxiliary air cooling effect. The power generator comprises auxiliary air channels. Air inlets of the auxiliary air channels are formed in covering parts, and the auxiliary air channels pass through gaps among an engine, a power generator body and the covering parts. The power generator has the advantages that the power generator is provided with auxiliary cooling air channel structures, the auxiliary cooling air channels can be used with main cooling air channels, preliminary cooling and heat-insulation effects can be realized, heat accumulation in a case can be initiatively eliminated, special heat-insulation processing on radiating positions can be omitted, accordingly, the integral structure of the power generator can be simplified, and the service cost can be saved; the structure of the power generator is further simplified, and accordingly merits of flexibility, mobility and the like of the small power generator can be exerted.

Description

Technical field [0001] The invention relates to an auxiliary structure of a generator, in particular to an auxiliary air-cooled generator. Background technique [0002] Small general-purpose machinery has a small volume and weight, and is widely used; for example, small fuel generators are often used in home life and other fields due to their small size and compact structure; because the generator uses an engine as power, With more heat generation, heat dissipation is a problem that the generator with this structure must solve; in the prior art, in order to dissipate heat, a structure that dissipates heat from the generator and the engine is adopted, and two cooling fans and independent The cooling air duct and the more complicated air duct structure make the generator structure larger in size and inconvenient to move and use. At the same time, in order to reduce the temperature in the generator box, the existing structure also uses a heat insulation layer to protect the power pa...

Problems solved by technology

[0002] Small general-purpose machinery has a small volume and weight, and is widely used; for example, small fuel generators are widely used in family life and other fields due to their small size and compact structure; because the generator uses an engine as power, therefore, There is a lot of heat generated, and heat dissipation is a problem that must be solved by the generator of this structure; in the prior art, in order to dissipate heat, a structure for dissipating heat from the generator and the engine is adopted, and two cooling fans and independent cooling fans are used. Cooling air duct, the more complex air duct structure makes the whole generator structure larger and inconvenient to move and use; at the same time, in order to reduce the temperature in the generator box, the existing structure also uses a heat insulation layer to cover the power part Parts and the muffler part of the thermal insulation are completely wrapped to reduce the influence of the thermal insulation on the temperature inside the generator box, so the structure is more complicated, resulting in the small generator not being able to give full play to its advantages of flexibility and compactness
