Internal combustion engine powered system, charge air cooler assembly, and method of cooling charge air

A charge air cooler assembly for air cooling, comprising:

• a radiator;
• an air driver;
• a first stage air-to-air cooler configured to receive first charge air, the first stage air-to-air cooler arranged to direct the first charge air along a first direction from an inlet of the first stage air-to-air cooler to an outlet of the first stage air-to-air cooler;
• and
• a second stage air-to-air cooler configured to receive second charge air, the second stage air-to-air cooler being separate from the first stage air-to-air cooler and arranged to direct the second charge air away from the first stage air-to-air cooler along a second direction from an inlet of the second stage air-to-air cooler to an outlet of the second stage air-to-air cooler, the second direction being different from the first direction, the first stage air-to-air cooler and the second stage air-to-air cooler together surrounding the radiator on at least two sides, the air driver positioned axially behind each of the first stage air-to-air cooler, the second stage air-to-air cooler, and the radiator.

A method of cooling charge air for an internal combustion engine system, comprising:

• compressing air using a first stage turbocharger to produce a first charge air;
• cooling the first charge air by passing the first charge air through a first stage air-to-air cooler that is disposed on a first side of a radiator, by passing the first charge air along a first direction through the first stage air-to-air cooler;
• compressing the first charge air using a second stage turbocharger to produce a second charge air;
• and
• cooling the second charge air by passing the second charge air through a second stage air-to-air cooler that is separate from the first stage air-to-air cooler and that is disposed on a second side of the radiator, by passing the second charge air away from the first stage air-to-air cooler along a second direction that is different from the first direction, the cooling comprising providing air to the first stage air-to-air cooler and the second stage air-to-air cooler from an air driver positioned axially between (i) the internal combustion engine, and (ii) the first stage air-to-air cooler, the second stage air-to-air cooler, and the radiator.
