Variable oil cooler tube size for combo cooler

摘要

A combination cooler includes a first circuit having a first series of tubes defining a first hydraulic diameter. The first fluid circuit is adapted to communicate a first fluid from a first inlet to a first outlet. A second fluid circuit includes a second series of tubes defining a second hydraulic diameter and a third series of tubes defining a third hydraulic diameter. The second fluid circuit is adapted to communicate a second fluid from a second inlet to a second outlet. The first and second hydraulic diameters are equivalent. The third hydraulic diameter is distinct from the first and second hydraulic diameter.
