Abstract

The invention relates to an excavator. The excavator comprises: a cooling fan (1), which is an electric fan; and a storage battery (3), which is electrically connected to the cooling fan (1) to provide electric energy for the cooling fan (1), The electric fan (1) powered by the storage battery (3) is used to cool down and cool the multiple parts of the engine, thus improving the problem in the related art that the fan is not controllable due to the rotation of the fan with the engine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an excavator. Background technique [0002] During the use of the excavator, the system generates a lot of heat, which requires a cooling fan to dissipate heat. At present, the most used heat dissipation method is that the engine and the fan are directly connected through a coupling, and the fan runs with the start of the engine. This type of connection fan There is no speed adjustment function. In addition, hydraulic variable pumps or load-sensitive pumps are used to hydraulically drive the fan motor to control the operation of the fan. The speed of the fan is adjustable, but the price of the hydraulic components is high, the efficiency is low, and the energy-saving effect and economy are poor. [0003] In the related art, the cooling system applied to the hydraulically driven fan mode includes an engine electronic control module and a cooling system controller, and a hydra...
