Embodiment Construction

[0020] refer to figure 1 , where a machine 10 is shown, which may take the form of, for example, an articulated dump truck or other work vehicle having a fore-aft axis 11 . Exemplarily, as an articulated dump truck, machine 10 has a front 12 and a rear that are articulated to each other and positioned along a front-to-rear axis 11 . The front section 12 has an operator's position and an engine compartment 18 forward of the operator's position. The rear has a tiltable dump body configured to carry cargo.

[0021] Machine 10 has a cooling system 22 for cooling various fluids in machine 10 . The cooling system 22 has a first cooling assembly 24 , a second cooling assembly 26 and a fan control system 28 .

[0022] The first cooling assembly 24 has a first fan 30 and at least one heat exchanger 32 to cool at least one fluid associated with the machine 10 . The first fan 30 is configured to rotate in a cooling or forward direction 34-1 and an opposite cleaning or reverse directi...

Abstract

A cooling system comprises a first cooling package, a second cooling package, and a fan control system. The first cooling package comprises a first fan and at least one heat exchanger to cool at least one fluid associated with the machine. The first fan is configured to rotate in a cooling direction and an opposite cleaning direction. The second cooling package comprises a second fan and at least one heat exchanger to cool at least one fluid associated with the machine. The second fan is configured to rotate in a cooling direction and an opposite cleaning direction. The fan control system is configured to alternate the first and second fans between a first cleaning mode and a second cleaning mode.

Description

technical field [0001] The present invention relates to a cooling system for cooling one or more fluids in a machine. Background technique [0002] Exhaust emission standards are becoming more and more stringent. These standards will increase the heat loss requirements in the cooling system of off-road equipment. [0003] Vehicles use a cooling system to cool the engine, reducer, transmission, brakes and air conditioning condenser. The coolers of the cooling system become dirty after a period of use and, at least in some cases, are cleaned manually by blowing out the coolers with an air gun. This maintenance process takes time and becomes more difficult as the remaining dirt builds up. It also increases the non-productive time of the vehicle. If left untreated, the vehicle will begin to overheat and lose performance, and could eventually fail one of its major components. Contents of the invention [0004] According to the present disclosure, a cooling system includes ...
