The present disclosure relates to a power cabin of an electric transmission engineering machine, including: an engine cabin, with an engine and a generator inside; a cooling cabin, with a cooling fan and a radiator module inside; One side of the cooling compartment is provided with a power battery pack and electronic control components inside; wherein, the electrical compartment and the engine compartment are air-isolated from each other, and the electrical compartment is provided with a first air inlet grille for External air is introduced into the electrical compartment. The embodiments of the present disclosure can improve heat dissipation efficiency, reduce heat radiation received by electrical components, and keep the power cabin within an appropriate temperature range.
Description
technical field [0001] The present disclosure relates to the field of engineering machinery, in particular to an electric transmission engineering machinery power cabin and engineering machinery. Background technique [0002] Electric transmission construction machinery is a type of construction machinery that uses electric energy to drive the motor to drive the wheels, and relies on sensors and electronic control systems to realize man-machine dialogue, thereby eliminating the need for reducers, differentials and mechanical control systems. Its main cooling objects include engines , generators, traction motors, power batteries and control systems. [0003] Affected by many factors such as the overall layout of the relevant power cabin, the cooling module and the rotation effect of the cooling fan blades, the flow state of the cooling air in the power cabin becomes complicated and difficult to control, which is very detrimental to the normal operation of the radiator and the...
