Air duct structure of generator set and vehicle-mounted generator set

Abstract

The invention discloses an air duct structure of a generator set and a vehicle-mounted generator set. The air duct structure comprises a case, in which an engine, a motor and a silencer are arranged. An engine air inlet is formed in the case on one side of the engine. Air of the engine air inlet is used for cooling the engine. A motor air inlet is formed in the case on one side of the motor. One part of air entering the motor air inlet is exhausted out of the case by means of a magneto air duct exhaust outlet. The other part of air enters the case by means of a motor air-guiding cover. A first gust of air is formed in the case. Air of the engine air inlet enters the case via the engine so that a second gust of air is formed in the case. After being mixed, the first gust of air and the second gust of air are exhausted out of a silencer air exhaust by passing a silencer air duct. The silencer is arranged in the silencer air duct. The silencer air exhaust is arranged in the case. The air duct structure of the generator set and the vehicle-mounted generator set have following beneficial effects: temperature of air and temperature rise of all assemblies in the case is decreased; service lifetime of the generator set is prolonged; and power generation efficiency is increased.

Description

technical field [0001] The invention relates to a generator set, in particular to an air duct structure of the generator set and a vehicle-mounted generator set. Background technique [0002] The heating and cooling components of the generator set need to be cooled during operation to ensure its stable operation. [0003] Chinese patent CN201320814734.4 discloses a new air-cooled vehicle-mounted gasoline generator, and Chinese patent ZL2008101965459 discloses a cooling method dedicated to generators and a closed gasoline generator set using the method. The hot air after the cooling of the above engines and motors is collected and discharged together through the sounder air duct. [0004] In the existing vehicle-mounted gasoline generator air duct structure, the hot air after the heat exchange of the engine in the chassis and the hot air after the heat dissipation of the magneto are discharged through the muffler air duct together, and the two hot air influence each other, a...

Problems solved by technology

[0004] In the existing vehicle-mounted gasoline generator air duct structure, the hot air after the heat exchange of the engine in the chassis and the hot air after the heat dissipation of the magneto are discharged through the muffler air duct together, and the two hot air influence each other, and the exhaust resistance increases. The heat exchange efficiency with the engine is reduced, and the temperature rise is high, resulting in a decrease in power generation efficiency
