Quiet air-cooled generator set

Abstract

The invention provides a mute air-cooled generating set which comprises a chassis and a soundproof box. An engine and a generator coaxially connected with the engine are arranged in a space formed by the surrounding of the soundproof box and the chassis; the soundproof box and / or the chassis is provided with an air port; an exhaust fan coaxially connected with a flywheel is arranged at one side of the flywheel of the engine; the exhaust fan is covered with an exhaust wind scooper; an air inlet of the exhaust wind scooper is positioned in the soundproof box; an air outlet of the exhaust wind scooper is communicated with an exhaust chamber; the exhaust chamber is communicated with the atmosphere outside the soundproof box. When the mute air-cooled generating set operates, gas in the soundproof box is constantly extracted by the exhaust fan, is led into the exhaust chamber and is discharged into the atmosphere from air outlets on the periphery of the exhaust chamber, at the moment, hot gas in the soundproof box is exhausted, the gas pressure is reduced, cold air outside the soundproof box can be continuously supplemented into the soundproof box through air inlets preset on the soundproof box or the chassis so as to form a circular cooling system, thereby effectively reducing the temperature in the soundproof box.

Description

technical field [0001] The invention relates to a silent air-cooled generating set. Background technique [0002] Generator sets are generally widely used as civil and industrial power sources to meet the power needs of many occasions such as homes, schools, hospitals, and construction sites. However, most of the products currently on the market are open-frame products. Because the engine is directly exposed to the outside, there is a defect of high noise level, which cannot meet the needs of quiet workplaces and night work environments. [0003] If in order to minimize the noise, the engine and generator are sealed with a soundproof box and the number of air inlets and outlets is greatly reduced, the heat in the soundproof box will continue to accumulate due to the heat radiation generated by the operation of the engine and generator, causing the temperature to rise. The original heat balance of the generating set is broken. The cooling effect of the engine and generator ...

AI Technical Summary

Problems solved by technology

The cooling effect of the engine and generator becomes worse, which affects the reduction of output power and the reliability of the generator set

[0004] Due to the above technical difficulties, the upgrade of generator sets to the direction of low noise is limited, and there are few low-noise generator sets recognized and accepted by users in the market
