Air-cooled structure of power generation set

Abstract

The invention discloses an air-cooled structure of a power generation set. The air-cooled structure comprises a power generation unit which is formed by an engine and a power generator; the front end of the engine serves as a first cold air inlet; a motor shaft of the power generator is connected with an output shaft of the engine; the rear end of the power generator serves as a second cold air inlet; a wind collection volute casing is arranged between the rear end of the engine and the front end of the power generator; a spiral cooling air duct is formed in the wind collection volute casing; the motor shaft which is arranged in the wind collection volute casing is provided with a cooling fan; the top of the engine is provided with a wind collection cover; an exhaust pipe of the engine extends from the wind collection cover to be located above the power generator; a noise reduction cooling cover which is connected with the wind collection cover is arranged outside the exhaust pipe; an air outlet of the wind collection volute casing is communicated with the noise reduction cooling cover. According to the air-cooled structure of the power generation set, the cooling effect is good and accordingly the stability of the work of the power generation set is ensured and the amplitude of the power reduction due to the temperature rise is small.

Description

Technical field [0001] The invention relates to a generator set, in particular to an air-cooled structure of the generator set. Background technique [0002] Generating sets are widely used in long-term (temporary) electricity consumption by small and medium-sized enterprises such as industries, commerce, schools, hospitals, etc., and play a good supplementary role in the lack of city electricity. As we all know, the heat dissipation and cooling of the generator set is the key technology to ensure its normal operation. Because the temperature of the generator set increases (≥130℃) during operation, the power will drop and the fuel consumption will increase within a few hours of operation. , Even the failure of automatic shutdown due to black smoke. [0003] At present, the existing cooling and cooling structures used for generating sets generally have unsatisfactory cooling effects, which results in the entire generating set working not being stable enough, and the power decline w...

AI Technical Summary

Problems solved by technology

[0003] At present, the cooling effect of the existing cooling structure used for generating sets is generally not satisfactory, which leads to the unstable operation of the entire generating set, and the power decline with temperature rise is still relatively large, so there are still certain limitations in the cooling technology.
