摘要
A double air-exhaust type synchronous generator includes a housing (1) arranged inside a sealed box, a stator (2), a rotor (3) and a central shaft (4). The front end of the central shaft (4) is connected to an output shaft of an engine, and the rear end of the central shaft (4) is mounted on the rear portion of the housing (1) by a bearing seat (5) and a bearing (6) arranged inside the housing (1). A front fan (7) with at least two front centrifugal blades (8) is fixedly mounted outside the front end of the central shaft (4). A front air exhaust opening (9) is arranged on the side wall of the front portion of the housing (1) and a rear air intake opening (10) is arranged on the side wall of the rear portion of the housing (1). A fan casing (11) is fixedly mounted on the rear end of the housing (1), and several air-induced holes (12) are formed on the side wall of the front portion of the fan casing (11). A rear fan (13) is provided inside the fan casing (11), and the front end of the rear fan shaft (14) thereof is fixedly connected with the central shaft (4) across the walls of the fan casing (11) and the casing (1). An air-cooling ultra-silent generating set including the double air exhaust type synchronous generator and a front double air-exhaust type synchronous generator are also disclosed. The generators and generating set are small in noise, and can effectively control temperature rise while maintaining original power.
