Abstract

The invention discloses a generator which comprises an end cover, a generator part, a motor bracket and an induced air shell, wherein the generator part consists of a stator, a rotor, a rotor shaft and a generator cooling fan; the induced air shell is divided into two cavities by a middle clapboard, the front cavity is connected with the motor bracket and is provided with an air inlet in the side wall, and the rear cavity is provided with a fan which is coaxially connected with the rotor and is provided with an air outlet in the side wall; and one side, which is axially opposite to the middle clapboard, of the rear cavity is provided with an exhaust opening. A ventilation channel is arranged in the manner that for the first ventilation channel, cooling air is sucked into the front cavity of the induced air shell from the air inlet in the side wall of the front cavity of the induced air shell, cools the generator and then is exhausted by the generator cooling fan through the air outlet of the generator; and for the second ventilation channel, air is sucked from the exhaust opening in the cavity from the fan in the rear cavity of the induced air shell and is exhausted through the air outlet in the side wall of the cavity. The generator has the advantages of small noise, temperature rise and invariable output power.

Description

technical field [0001] The invention relates to the field of generators, in particular to a generator with a forced ventilation system. Background technique [0002] Engine-driven 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] Usually, in order to minimize the noise, the engine and generator are installed in the closed casing, and a small amount of air inlet and outlet are opened. Due to the heat radiation generated by the operation of the engine and generator, the heat in the closed casing will continue to accumulate. As a result, the temperature rises, and the original heat balance of th...
