Abstract

A cooling device includes a first radiator core, a second radiator core, a fan, a ventilation component, and a blocked part. The first radiator core and the second radiator core ( 42 ) are disposed adjacently with a specific space in between. The fan supplies air to the first radiator core and the second radiator core. The ventilation component is formed in part of the specific space and transmits air supplied from the fan. The blocked part is formed by a blocking member disposed in a different part of the specific space from the ventilation component.

Claims (39)

1. A cooling device, comprising:

a first radiator core disposed adjacent a second radiator core, the first radiator core and the second radiator core being spaced apart with a specific space in between;

a fan that supplies air to the first radiator core and the second radiator core;

a ventilation component formed in part of the specific space and through which air supplied from the fan passes; and

a blocked part formed by a blocking member disposed in a different part of the specific space from the ventilation component, the blocking member spanning an entire width of the specific space in a direction in which the first radiator core and the second radiator core are spaced apart,

the first radiator core having a first incoming air face for receiving the air supplied from the fan, and the second radiator having a second incoming air face for receiving the air supplied from the fan, the first incoming air face and the second incoming air face being arranged to extend in the direction in which the first radiator core and the second radiator core are spaced apart.

2. The cooling device according to claim 1 , wherein

the ventilation component is arranged to at least partially overlap with a component molded from plastic when the ventilation component is viewed along a direction in which the air passes through the ventilation component.

3. The cooling device according to claim 2 , wherein

the fan is disposed between the component and the first radiator core and between the component and the second radiator core.

4. The cooling device according to claim 2 , wherein

the component is an engine air cleaner.

5. The cooling device according to claim 1 , wherein

the first incoming air face and the second incoming air face are arranged in the same plane.

6. The cooling device according to claim 1 , wherein

the first incoming air face and the second incoming air face are arranged perpendicular to an air blowing direction of the air supplied from the fan.

7. A cooling device, comprising:

a first radiator core disposed adjacent a second radiator core, the first radiator core and the second radiator core being spaced apart with a specific space in between;

a fan that supplies air to the first radiator core and the second radiator core;

a ventilation component formed in part of the specific space and through which air supplied from the fan passes; and

a blocked part formed by a blocking member disposed in a different part of the specific space from the ventilation component, the blocking member spanning an entire width of the specific space in a direction in which the first radiator core and the second radiator core are spaced apart,

the blocking member contacts the first radiator core and the second radiator core.

8. A cooling device, comprising:

a first radiator core disposed adjacent a second radiator core with a specific space in between;

a fan that supplies air to the first radiator core and the second radiator core;

a ventilation component formed in part of the specific space and through which air supplied from the fan passes; and

a blocked part formed by a blocking member disposed in a different part of the specific space from the ventilation component,

the first radiator core and the second radiator core being disposed adjacent one another in a horizontal direction,

the ventilation component being formed above a center position in the up and down direction, and

the blocked part is formed below the ventilation component.

9. A work vehicle, comprising:

a cooling device having

a first radiator core disposed adjacent a second radiator core, the first radiator core and the second radiator core being spaced apart with a specific space in between,

a fan that supplies air to the first radiator core and the second radiator core,

a ventilation component formed in part of the specific space and through which air supplied from the fan passes, and

a blocked part formed by a blocking member disposed in a different part of the specific space from the ventilation component, the blocking member spanning an entire width of the specific space in a direction in which the first radiator core and the second radiator core are spaced apart,

the first radiator core having a first incoming air face for receiving the air supplied from the fan, and the second radiator having a second incoming air face for receiving the air supplied from the fan, the first incoming air face and the second incoming air face being arranged to extend in the direction in which the first radiator core and the second radiator core are spaced apart; and

a component arranged and configured to at least partially overlap with the ventilation component when viewed along a direction in which the air passes through the ventilation component,

the component being molded from plastic.
