きる。 According to such a fan cooling device, one wide stay 17 is arranged from the motor mounting hole 16 to the fan mounting opening 15, and the fan 23 is attached to the wide one stay 17.
The installation operation in Step 3 becomes much easier. Also, motor M
The belt 28 that transmits the rotation of the fan 23 to the fan 23 is protected by the stay 17 and the cover 29, which have a U-shaped cross section, and is not adversely affected by the wind passing through the fan mounting opening 15, eliminating the vibration of the belt 28 caused by the wind. The rotation of the motor M is smoothly and reliably transmitted to the fan 23. Of course, belt noise caused by wind is also eliminated. Moreover, since the motor M is not directly connected to the fan 23 but is provided in another part, the longitudinal width l of the device can be reduced, as shown in FIG. 4, and the motor M can be placed in a well-ventilated place. This makes it possible to prevent the motor M from overheating. Furthermore, by appropriately changing the outer diameters of the pulleys 26 and 27 provided on the fan 23 and the rotating shafts 24 and 25 of the motor M, the rotational speed of the fan 23 can be changed to suit the size, type, etc. of the radiator R. The fan rotation speed can be adjusted accordingly, the motor M can be driven with optimal efficiency, and the radiator R can always be appropriately cooled in the best condition.

5, one wide stay 31 placed across the motor mounting hole 1 is made shorter on the side of the fan mounting opening 15.
Only the 6 side is fixed with bolts, nuts, etc., and the fan 23 and motor M are supported by this stay 31.

バーを取付ける。 In this case as well, since the fan 23 is attached to one stay 31, the operation for attaching the fan 23 becomes easy. In addition, since the belt 28 is protected by the stay 31 having a U-shaped cross section, the belt 28 is protected by the wind.
The vibrations are eliminated, the rotation of the motor M is smoothly transmitted to the fan 23, and the radiator R can be effectively cooled. Furthermore, belt noise caused by wind is also eliminated. Moreover, the front and rear width of the device can be reduced.
Effects similar to those of the previous embodiment, such as preventing the motor M from overheating, can be obtained. In this case, stay 3
Since 1 is short, the material of the stay 31 can be saved and the weight can be reduced. In this case as well, a cover is attached to the stay 31.

を防止している。 Fig. 8 and Fig. 9 are simplified illustrations of the stay 3 arranged from the motor mounting hole to the fan mounting opening.
This is an example in which covers are not attached to parts 2 and 33. Even in such a case, the belt 28 is protected from the wind passing through the fan mounting opening, thereby preventing vibration of the belt 28 due to the wind.

冷却に利用できるものである。 In the above embodiment, the rotation of the motor M is transmitted through the belt 28, but it goes without saying that other endless ropes such as ropes and chains can be used as necessary. Further, the present invention can be used not only for cooling radiators but also for cooling other heat exchangers such as condensers.

等の種々の顕著なる効果を奏する。 According to the present invention, the fan is attached to a single stay, so the installation of the fan is very simple. Also, the belt that transmits the rotation is protected by a wide stay with a U-shaped cross section or a cover attached to the stay, so the vibration of the endless rope caused by wind is eliminated, and the rotation of the motor is transmitted smoothly and reliably to the fan, effectively cooling the heat exchanger. Of course, the noise of the endless rope caused by wind is also eliminated. Moreover, by installing the motor in another part instead of directly connecting it to the fan, the front-to-rear width of the device is reduced, and by placing the motor in a well-ventilated place, it is possible to prevent overheating, and other remarkable effects are achieved.
