Silent variable frequency generator

Abstract

The invention discloses a silent variable frequency generator. The generator comprises a shell assembly composed of an upper shell and a lower shell, an engine is arranged in the lower shell, and a silencer and a stator and rotor component with a cooling fan are arranged on the two sides of the engine. A wind scooper and an air guide hood are arranged in the shell assembly, the wind scooper surrounds the stator and rotor component, and the air guide hood surrounds the engine and the silencer. A fuel tank, a fuel transfer unit and an inverter unit are arranged in the shell assembly, and the fuel tank and the fuel transfer unit are arranged on one side of the engine and are far away from the inverter unit. The silent variable frequency generator has the advantages of ingenious structure design and reliable use. The volume of the fuel tank can be increased without increasing the size of the whole machine, and the heat dissipation performance of the generator is ensured. In addition, the fire risk caused by fuel leakage due to a fuel pipeline being broken is effectively reduced. Moreover, due to the unique design mode of the upper shell and the lower shell being formed in one body, themanufacturing and assembly costs are reduced.

Description

technical field [0001] The invention relates to a generator, in particular to a silent variable frequency generator. Background technique [0002] Due to the continuous improvement of the material level, people's requirements for small generator products are no longer limited to meeting simple electricity needs, and people have put forward higher requirements in terms of generator appearance, size, weight, safety, etc. , the existing small generators on the market usually have to make some compromises in these aspects, such as reducing the internal space of the generator, but the result may be that the heat dissipation effect of the generator is poor. This design will lead to long-term high-load use Affect the service life of the generator, or reduce the capacity of the fuel tank to reduce the size of the generator. However, this will cause users to frequently refuel or refuel at night when the demand for electricity is large, which brings great harm to life and production. ...

AI Technical Summary

Problems solved by technology

It can be seen from the patent that the shell structure adopts the design of the combined cover, which is not conducive to the assembly of the generator, and the manufacturing cost is high. In addition, due to the close distance between the fuel tank and the inverter, when the fuel tank ruptures and leaks, Fuel may come into direct contact with live parts, posing a fire risk
