Abstract
A heat exchanger is provided for dissipating heat from a dual turbocharged engine. The heat exchanger has a jacket water cooler, and first and second charge air coolers. The three coolers are arranged in parallel enabling each to operate with a maximum temperature differential, and have fronts that lie in parallel planes. Charge air from a first turbocharger is directly piped to the first charge air cooler, and charge air from the second turbocharger is directly piped to the second charge air cooler. A first baffle is between and upstream of the first charge air cooler and the jacket water cooler. A second baffle is between and upstream of the second charge air cooler and the jacket water cooler. The baffles can direct selected amounts of air to each of the three coolers and prevent radial convective scrubbing. A fuel oil cooler can also be provided.
