ーの交換が充分に行われ得る。In the engine cooling device according to the present invention, the heat exchange device exchanges heat energy with the radially outer portion of the air flow generated by the rotary fan. Cooling is performed by the radially inner part of the air flow generated by the fan, so that the heat exchange device and the engine exchange heat between different parts of the air flow generated by the rotary fan. The cooling of the engine by the radially inner portion of the air flow generated by the rotary fan is always ensured to a certain extent.

Is almost always constant. Furthermore, the heat exchange device is
Since heat energy is exchanged with the radially outer part of the air flow generated by the rotary fan, the heat flow is larger than the flow velocity of the radially inner part of the air flow generated by the rotary fan. The exchange of heat energy in the device to be heat-exchanged is performed between the flow of air at the flow velocity and the exchange of heat energy between the device to be heat-exchanged and the flow of air generated by the fan.
