Radiator arrangement with offset modular cores

A modular radiator arrangement for a work machine comprising:

• a fan having a plurality of blades and being rotatable to induce cooling air flow;
• a plurality of elongated radiator core modules each having a plurality of spaced substantially parallel fluid passing tubes and a plurality of spaced substantially parallel fins transversely oriented relative to and connected to said fluid passing tubes;
• a first row of substantially parallel consecutive radiator core modules, said radiator core modules being spaced a predetermined distance apart and defining a first space between consecutive pairs of said modules;
• a second row of substantially parallel consecutive radiator core modules, said radiator core modules of the second row being spaced a predetermined distance apart and defining a second space between consecutive pairs of radiator core modules of the second row, said second row of radiator core modules being located a predetermined spaced distance from the first row of radiator core modules and between the fan and the first row of radiator core modules, each module of the second row of consecutive modules being aligned with a different first space;
• and
• an air directing duct is disposed in each of the first spaces and about the radiator core modules of the second row of radiator core modules aligned with the first spaces, said air directing ducts direct airflow induced by the fan in bypass of the first row of radiator core modules and through the second row of radiator core modules and directs air flow induced by the fan through the first row of radiator core modules and in bypass of the second row of radiator core modules.
