ではない。By the way, in order to prevent interference between the vehicle equipment and the cross flow fan 10f, regardless of the axial position,
Means such as reducing the fan diameter over the entire area in the axial direction is conceivable. However, with this means, the blowing ability itself of the second blower 10b is reduced, and the cooling capacity of the radiator 4 and the radiator 5 is reduced. . Further, since the vehicle equipment such as the engine mount member 1a and the exhaust manifold 1b do not need to be particularly cooled,
It is not advisable to reduce the overall fan diameter of the cross flow fan 10f for vehicle equipment that does not need to be cooled.

Although only the cross flow fan 10f of No. 0b changes the fan diameter by the axial portion, the present invention is not limited to this, and the fan diameter of the cross flow fan 10f of the first blower 10a is changed by the axial portion. It may be changed. In the above-described embodiment, both the blowers 10
a and 10b are disposed on the downstream side of the air flow from the radiator 4, but both the blowers 10a and 10b are connected to the radiator 4
Alternatively, it may be disposed upstream of the radiator 5 in the air flow. Thus, interference between vehicle equipment such as a bumper and a cross member on the front side of the vehicle and the cross flow fan 10f can be prevented.
