Abstract

A cooling system includes a rear radiator that is mounted in a vehicle and circulates cooling water to release heat of the cooling water. A fan that generates cooling air to cool the rear radiator, and a shroud is provided between the fan and the rear radiator and guides the cooling air. The shroud has a double structure having an internal space; the internal space enables the cooling water to pass through the internal space when the cooling water circulates.

Claims

1. A cooling system, comprising:

a radiator that is mounted in a vehicle and circulates a cooling medium to release heat of the cooling medium;

a fan configured to generate cooling air to cool the radiator; and

a shroud that is provided between the fan and the radiator and is configured to guide the cooling air,

wherein the shroud comprises a double structure having an internal space,

wherein the internal space is configured to enable the cooling medium to pass through the internal space when the cooling medium circulates,

wherein the radiator is mounted in a saddle-type vehicle as the vehicle, and

wherein an additional radiator configured to circulate the cooling medium common with the radiator is provided at a front part of the vehicle.

2. The cooling system according to claim 1, wherein the shroud includes, as the double structure:

an inner portion having a tubular shape; and

an outer portion that is provided outside the inner portion in a radial direction and has a tubular shape,

wherein the internal space is formed between the inner portion and the outer portion.

3. The cooling system according to claim 1,

wherein the shroud includes partition wall parts that divide the internal space into a first internal space through which the cooling medium is configured to pass, and

a second internal space through which the cooling medium that has passed through the first internal space is configured to pass.

4. The cooling system according to claim 3, wherein:

the partition wall parts divide the internal space into upper and lower spaces, and

wherein the second internal space is disposed under the first internal space.

5. The cooling system according to claim 3,

wherein the cooling system is configured to cause the cooling medium to flow in order of the first internal space, the radiator, and the second internal space.

6. The cooling system according to claim 1,

wherein a radiating fin that is configured to release the heat of the cooling medium is provided on a surface facing an air guiding space to which the cooling air is guided in the shroud.

7. The cooling system according to claim 1,

wherein the fan is disposed on an upstream side relative to the radiator in a flow direction of the cooling air.

8. A cooling system, comprising:

radiator means for circulating a cooling medium to release heat of the cooling medium, said radiator means being mounted in a vehicle;

air circulation means for circulating cooling air for cooling the radiator means;

shroud means disposed between the air circulation means and the radiator means, said shroud means for guiding the cooling air; and

radiating fin means for releasing the heat of the cooling medium, said radiating fin means provided on a surface facing an air guiding space to which the cooling air is guided in the shroud means,

wherein the shroud means includes double structure means for providing an internal space therein, and wherein the internal space enables the cooling medium to pass through the internal space when the cooling medium circulates.

9. The cooling system according to claim 8, wherein the shroud means includes, as the double structure means, an inner portion having a tubular shape, and an outer portion disposed outside the inner portion in a radial direction and having a tubular shape,

wherein the internal space is disposed between the inner portion and the outer portion.

10. The cooling system according to claim 8, wherein the shroud means includes partition wall means for dividing the internal space into a first internal space through which the cooling medium is configured to pass, and a second internal space through which the cooling medium that has passed through the first internal space is configured to pass.

11. The cooling system according to claim 10, wherein the partition wall means is for dividing the internal space into upper and lower spaces, and wherein the second internal space is disposed under the first internal space.

12. The cooling system according to claim 10, wherein the cooling system is configured to cause the cooling medium to flow in order of the first internal space, the radiator means, and the second internal space.

13. The cooling system according to claim 8, wherein the air circulating means is disposed on an upstream side relative to the radiator means in a flow direction of the cooling air.

14. A cooling system, comprising:

radiator means for circulating a cooling medium to release heat of the cooling medium, said radiator means being mounted in a vehicle;

air circulation means for circulating cooling air for cooling the radiator means; and

shroud means disposed between the air circulation means and the radiator means, said shroud means for guiding the cooling air,

wherein the shroud means includes double structure means for providing an internal space therein, and wherein the internal space enables the cooling medium to pass through the internal space when the cooling medium circulates, and

wherein the radiator means is mounted in a saddle-type vehicle as the vehicle, and wherein the cooling system further comprises additional radiator means for circulating the cooling medium common with the radiator means, said additional radiator means being disposed at a front part of the vehicle.
