Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a radiator device, and more particularly to a radiator device suitable for a cab-over type vehicle.

[Conventional technology]

Generally, in a cab-over type vehicle, an engine fan that is rotated by an engine is arranged in order to efficiently send air to a radiator and enhance cooling efficiency of the radiator.

As a cab-over type vehicle equipped with such an engine fan, for example, one disclosed in Japanese Utility Model Laid-Open No. 50-157626 is known.

FIG. 2 shows a cab-over type vehicle equipped with this type of engine fan, and in the figure, reference numeral 11 indicates a driver's cab arranged entirely above the cab-over type vehicle. , Driver's seat 13 is arranged.

A grill 15 is placed in front of the cab 11.
A bumper 17 is arranged below 15.

A radiator 19 is vertically arranged below the driver's seat 13 of the cab 11, and an engine fan 23 rotated by an engine 21 is arranged on the back side surface of the radiator 19.

In addition, a capacitor is placed between the bumper 17 and the radiator 19.
25 are arranged horizontally.

In such a cab-over type vehicle, by rotating the engine fan 23 by the engine 21, the atmosphere is introduced as shown by the arrow in the figure, and the air can be efficiently circulated to the radiator 19.

[Problems to be solved by the device]

However, in such a conventional cab-over type vehicle, since the radiator 19 needs to be vertically arranged below the driver's seat 13, there is a problem that the foot space 27 of the cab 11 is extremely limited and the habitability is poor. .

Further, in such a cab-over type vehicle, since the engine fan 23 is used, it is difficult to freely control the rotation of the fan.

Therefore, it has been conventionally considered to use a motor fan, but in this case, a high-output motor fan is required to suck in the atmosphere, and the power consumption increases, so it has not yet been put to practical use. Not.

As a result of earnest studies to solve such a conventional problem, the present inventor has found that the radiator can be sufficiently cooled by a motor fan having a relatively small output by efficiently introducing the atmosphere into the radiator.

The present invention has been made based on such knowledge, and an object of the present invention is to provide a radiator device for a cab-over type vehicle that enables a motor fan by efficiently introducing the atmosphere into the radiator.

[Means for Solving the Problems]

A radiator device in a cab-over type vehicle according to the present invention is a cab-over type vehicle in which a driver's cab is arranged above the radiator, a grill is arranged in front of the driver's cab, and a bumper is arranged below the grill. In order to prevent wind from entering the grill, the grill is shielded and the radiator is located in the space under the driver's cab, and the radiator is inclined in such a manner that the front side of the radiator faces the bumper side. A motor fan for sucking air is arranged between the back side of the radiator and the driver's cab, and an opening is formed in the bumper.

[Action]

In the present invention, the grill is shielded so that the radiator is located in the space under the driver's cab, and the radiator is arranged so that the front side of the radiator faces the bumper side in this space. A motor fan that draws in the atmosphere is placed between the motor fan and the bumper, and an opening is formed in the bumper.Therefore, when the motor fan is rotated, the wind does not come in between the radiator and the cab from the grill. The pressure on the leeward side does not increase, and the atmosphere is efficiently introduced into the radiator from the opening of the bumper and the lower part of the vehicle.

〔Example〕

The present invention will now be described in detail with reference to an embodiment shown in the drawings.

FIG. 1 shows an embodiment of a radiator device in a cab-over type vehicle according to the present invention.
Shows a driver's cab arranged entirely above the cab-over vehicle, and a driver's seat 33 is arranged on the driver's cab 31.

A grill 35 is arranged in front of the cab 31.
A bumper 37 is arranged below the 35.

Therefore, in this embodiment, the foot space 39 of the cab 31 is
A radiator 41 is arranged below the.

This radiator 41 has a bumper 37 on the front side of the radiator 41.
It is arranged so as to be inclined toward the side.

And, between the back side of the radiator 41 and the cab 31,
A motor fan 47 that sucks in air is arranged.

Further, the bumper 37 has an opening 49 for introducing the atmosphere.
Is formed, and the circulation of the atmosphere is blocked over the entire surface of the grill 35.

On the front side of the radiator 41, the condenser 51 is
It is arranged in parallel with 41, and at the lower end of this condenser 51, a baffle plate 53 is formed at an acute angle with respect to the condenser 51.
Is fixed.

In such a cab-over type vehicle, by rotating the motor fan 47, as shown by the arrow in the figure, the bumper 37
Atmosphere is emitted from the opening 49 of the
To be introduced efficiently.

That is, in the radiator device in the cab-over type vehicle configured as described above, the grill 35 is shielded and the radiator 41 is positioned in the space under the driver's cab, and the front surface of the radiator 41 faces the bumper 37 side in this space. As shown in the figure, the motor fan 47 for sucking the atmosphere is arranged between the back side of the radiator 41 and the driver's cab 31, and the opening 49 is formed in the bumper 37. Is difficult to enter, radiator 41 and cab 31
Since there is no air flow between the
Rotating 47 turns opening 49 on bumper 37 and lower part of vehicle
The atmosphere is efficiently introduced into the radiator 41 from 55, and it is possible to easily realize a motor fan.

As a result, it is not necessary to vertically dispose the radiator 41 under the driver's seat 33, and it is possible to secure a sufficient space 39 under the driver's cab 31. In addition, the dotted line in the figure indicates the conventional foot space.

Further, since the motor fan 47 is used, it is possible to freely control the rotation of the fan.

Further, in this embodiment, since the entire surface of the grill 35 is shielded, the flow of the atmosphere flowing downward from the grill 35 is eliminated, and the radiator 41 can efficiently guide the atmosphere.

Further, in this embodiment, the baffle plate 53 is attached to the lower end of the condenser 51.
Since the above is arranged, it is possible to efficiently guide the air flowing in from the lower portion 55 of the vehicle by the radiator 41.

In the embodiment described above, an example in which the grill 35 is shielded and the air guide plate 53 is arranged at the lower end of the condenser 51 has been described, but by doing so, the atmosphere can be most efficiently emitted to the radiator 41. It is possible to guide the air, and for example, it is possible to guide the atmosphere about twice as large as that in the conventional case shown in FIG.

Also, the shielding of the grill 35 does not have to be a perfect seal,
Even if wind enters, it is good if the pressure on the motor fan side does not increase due to the wind.

[Effect of device]

As described above, in the present invention, in order to prevent wind from entering the grill, the grill is shielded so that the radiator is located in the space under the driver's cab, and the front surface of the radiator faces the bumper side in this space. The radiator is placed so that it faces the driver, a motor fan that sucks in the atmosphere is placed between the back side of the radiator and the driver's cab, and an opening is formed in the bumper so that the wind can be placed between the radiator and the driver's cab. When the motor fan is rotated because the air does not flow and the pressure does not increase, the atmosphere is efficiently introduced into the radiator from the opening of the bumper and the lower part of the vehicle, and it is possible to easily make a motor fan. There is.
