A vehicle-mounted variable frequency generator set

Abstract

The invention discloses a vehicle-mounted variable-frequency generator set. A left set side cover (8) of a shell is provided with an inverter combination (9), an engine wind scooper (2-1) is arranged on one side of an engine body inside the shell, a silencer (2-3) and a box body side cover (2-2) are arranged on the other side of the engine body, the box body side cover (2-2) is sequentially connected with a motor inner wind scooper (2-6), a motor air guide transition joint (2-7), a motor cooling fan (2-8), a motor flywheel (2-9), a motor stator (2-10) and a motor stator base (2-11), an engine fixing base (3) is arranged under an engine and generator combination (2), a first-stage shock absorption foot (10), a second-stage shock absorption foot (11) and a second-stage shock absorption support (4) are arranged on the bottom of an engine fixing base (3), and an air inlet I of the inverter combination (9), an air inlet II of a right set side cover (6) and an air inlet III of a set top cover (1) communicate with the interior of the shell.

Description

technical field [0001] The invention relates to a vehicle-mounted frequency conversion generator set. Background technique [0002] Vehicle-mounted variable frequency generator sets are mainly used in various motor vehicles. In order to meet the convenience and comfort of users, in addition to the functions of ordinary generator sets, they also have special requirements for vibration, noise, heat dissipation, and overall height. The vehicle frequency conversion generator set is composed of engine, motor, frequency conversion controller and other auxiliary devices. The engine converts the chemical energy released by combustion into mechanical energy, and the generator converts mechanical energy into electrical energy. Both of them will generate a lot of heat energy during the working process. The frequency converter will also generate a certain amount of heat when it converts AC and DC. The normal operation of the generator set requires a good ventilation environment inside ...

Problems solved by technology

On the other hand, the generator set will generate a lot of noise during the working process, which will endanger the normal life of the user. In order to reduce the noise, the generator set must be made into a fully enclosed structure, but in order to solve the heat dissipation problem of the machine after the machine is closed, It is also necessary to arrange a complex cooling air duct system, together with a better shock absorption system, the volume of the generator set is greatly increased, and the space of the motor vehicle is limited, and some models need to install the generator set under the chassis of the vehicle to meet the needs of the vehicle. Good passing performance, the volume, especially the height index, of the on-board generator set seriously affects its application on vehicles
