Abstract
A radiator and an oil cooler are arranged at a front surface side of a cooling fan in parallel with each other in a flow direction of the cooling air, an intercooler and a condenser are arranged in parallel at a front surface side of the radiator and oil cooler, and a fuel cooler is arranged at a front surface side of the condenser. By arranging respective heat exchangers such that the heat release amount thereof sequentially increases from the upstream side toward the downstream side in the flow direction of the cooling air, each heat exchanger can efficiently release the heat of the fluid to be cooled. By arranging the fuel cooler at the front surface side of the condenser, two heat exchangers of the condenser and the fuel cooler can be accommodated within a range of the thickness dimension of the intercooler.
