Abstract

The invention discloses a fan assembly, an air cooling system and an electric transmission construction machine. The fan assembly includes: a fan, including a fan inlet; An air duct and an air outlet sleeve, the air intake duct passes through the first housing and has a muffler duct section protruding from the first housing, the air outlet sleeve is installed on the first housing and covers It is arranged outside the muffler duct section and forms a first muffler cavity with the muffler duct section. The air inlet of the air inlet duct is used to input the air flow sent to the fan. The air outlet sleeve has an air outlet connected to the inlet of the fan, the air outlet of the sound-absorbing duct section is located in the air-outlet sleeve and is spaced from and communicated with the air-outlet of the air-outlet sleeve, at least two of the plurality of sound-absorbing structures The lengths of the sound-absorbing duct sections of the several sound-absorbing structures are different and / or the lengths of the air outlet sleeves of at least two sound-absorbing structures among the plurality of sound-absorbing structures are different.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a fan assembly, an air cooling system and an electric transmission engineering machinery. Background technique [0002] In construction machinery, fan components are often used to air-cool the components of construction machinery. These components often produce a lot of noise during work. The noise generated by the components of construction machinery will be transmitted to the outside through the air intake pipe of the fan, polluting the outside world, and the noise generated by the fan will also be transmitted to the outside through the pipe. . [0003] For example, electric transmission construction machinery, electric transmission construction machinery uses electric energy to drive the motor to drive the wheels, relying on sensors and electronic control systems to achieve man-machine dialogue, eliminating the need for reducers, differentials and mechanical control syste...
