Engine cooling unit for an earth working machine
A drive unit for earth working machines, driven with a liquid-cooled internal combustion engine, wherein the internal combustion engine is situated in the engine compartment with a bonnet, and is fitted with a main cooler (7) for cooling of cooling of the liquid of the internal combustion engine, and at least one auxiliary cooler, which is e.g. an intercooler of air for supercharging, an oil cooler, a cooler for air conditioning, etc. The main cooler (7) is provided with a first fan and is situated separately from the engine compartment. A common suction space (9) of air is situated between the engine compartment and the main cooler, which space is designed for sucking of air from the outside of the machine and comprises a first partition (11), situated to separate the common suction space (9) from the engine compartment, and a second partition (12). The main cooler (7) is situated behind the second partition (12), while the auxiliary cooler is situated in front of the first partition (11), wherein the first fan (8) of the main cooler (7) is situated for suction of the cooling air from the common suction space (9) and for its taking off to the outside of the machine, while the auxiliary cooler (6) is fitted with the second fan (5), which is also situated for sucking of the cooling air from the common suction space (9) and for its taking off through the engine space to the outside of the machine.
