Patent ID: 7506618

Claim:
A heat exchanger for an engine producing heat with at least one turbocharger charging air into charge air, said heat exchanger comprising: a jacket water cooler for dissipating heat from the engine; a first charge air cooler for cooling the charge air; a first baffle upstream of said jacket water cooler and said first charge air cooler, said first baffle having a first baffle first side and a first baffle second side, a second charge air cooler for cooling the charge air; and a second baffle upstream of said jacket water cooler and said second charge air cooler, said second baffle having a second baffle first side and a second baffle second side, wherein said first charge air cooler and said jacket water cooler operate in parallel, wherein an air mover causes air starting at the ambient air temperature to be divided by said first baffle and independently passes on said first baffle first side through said jacket water cooler and on said first baffle second side through said first charge air cooler, the ambient air temperature creating maximum entering temperature differentials respectively for each of said jacket water cooler and said first charge air cooler, wherein said second charge air cooler and said jacket water cooler operate in parallel, and wherein an air mover causes air starting at the ambient air temperature to be divided by said second baffle and independently passes on said second baffle first side through said jacket water cooler and on said second baffle second side through said second charge air cooler, the ambient air temperature creating maximum entering temperature differentials respectively for each of said jacket water cooler and said second charge air cooler.
