Abstract

The invention discloses an engine-driven generator set which comprises an engine, a generator, an induced air shell and a soundproof box, wherein the engine is coaxially connected with the generator and is arranged in the soundproof box; the induced air shell is divided into two cavities through a middle clapboard, the front cavity is connected with a motor bracket at the tail end of the generator, and a fan is arranged in the rear cavity; an exhaust cavity is formed in the soundproof box; and an exhaust silencer is arranged in the exhaust cavity, and one end of the exhaust silencer is connected with the engine through an exhaust pipe. A ventilation channel is arranged in a manner that for the first ventilation channel, cooling air outside the soundproof box cools the engine and then enters the exhaust cavity; for the second ventilation channel, cooling air outside the soundproof box cools the generator and is blown into the exhaust cavity; and for the third ventilation channel, hot air in the soundproof box is blown to the exhaust cavity through an air outlet in the side wall of the cavity. According to three ventilation channels, the exhaust silencer in the exhaust cavity is further cooled, and the air is mixed with exhausted air of the engine and is exhausted into atmosphere through the corresponding air outlet in the soundproof box.

Description

technical field [0001] The invention relates to a generator set, in particular to an engine-driven generator set, wherein the engine and the generator are coaxially connected and installed in a sound-proof box together with an air induction casing. 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 th...
