FIG. 1 shows a cooling circuit of an internal combustion engine including a cooling device of the present invention, which includes an internal combustion engine 101, a fan 102, a turbocharger 103, an aftercooler 104, water pumps 105 and 106, and an aftercooler radiator 10. It is composed of a radiator 20. The engine cooling water circuit 110 circulates cooling water through the internal combustion engine 101 → the radiator 20 → the water pump 105 → the internal combustion engine 101. The aftercooler cooling water circuit 120 circulates the cooling water through the aftercooler radiator 10, the water pump 106, the aftercooler 104, and the aftercooler radiator 10. FIG. 2 is a side view of the cooling device, in which an aftercooler radiator 10 which is an intake air cooler and a radiator 20 which is a cooling water cooler are arranged in series with respect to the air flow indicated by the arrow.

The ampa tank 1 and the lower tank 4 are connected by the water pipes of the aftercooler radiator 10 and the radiator 20.
【００１０】 図３は図１のＡ部の詳細断面図であり、アフタクーラ用ラジェータ１０の水管 １１とラジェータ２０の水管２１とは、それぞれロアタンク４のアフタクーラ用 ラジェータ部分５およびラジェータ部分６に接続している。水管１１および２１ にはフィン１２が装着されている。FIG. 3 is a detailed cross-sectional view of the portion A in FIG. 1. The water pipe 11 of the aftercooler radiator 10 and the water pipe 21 of the radiator 20 are connected to the aftercooler radiator portion 5 and the radiator portion 6 of the lower tank 4, respectively. ing. Fins 12 are attached to the water pipes 11 and 21.
