もなつていた。 In a motorcycle equipped with a water-cooled engine, the radiator for cooling the cooling water is located at the front of the vehicle body in a position where it easily receives cooling air. On the other hand, motorcycles have various devices mounted in a narrow space. In such a narrow space, if you lead the cooling water pipe that returns from the engine directly to the top of the radiator, or if you take out the water pipe that takes out the coolant that has been cooled by the radiator from the top of the radiator, the back side of the radiator Therefore, the presence of the water guide pipe makes it difficult for cooling air to pass through the radiator, reducing the cooling effect. Additionally, in order to secure space for running the water pipes, the radiator had to be placed in the front, or the equipment behind the radiator had to be moved back, which was an obstacle to making it more compact.

るものである。 The present invention achieves the above object by arranging an upper tank and a lower tank extending left and right one above the other, communicating between the two tanks through a plurality of cooling passages extending vertically in parallel, and connecting the two adjacent cooling passages. In a motorcycle in which a radiator configured such that cooling fins are connected between the radiators is attached to the front of the vehicle body so that the surface direction in which the plurality of cooling passages are lined faces the direction of travel of the vehicle body, cooling water is recirculated from the engine. A water guide pipe passes through the lower tank to communicate the inside of the radiator to the upper tank in parallel with the cooling passage, and a cooling fin connects the water guide pipe and the cooling passage, and the water guide pipe and the cooling passage are connected to each other. The feature is that the cooling water flows in opposite directions.

上を図ることができる。 By arranging the water guide pipe in parallel with the cooling passage so as to penetrate the lower tank and pass through the inside of the radiator, the water guide pipe does not occupy space at the back of the radiator, and a compact configuration can be achieved. In addition, the water guide pipes are arranged in parallel with the cooling passage and connected to each other by cooling fins, so that they are themselves directly cooled by the cooling air and do not obstruct the passage of the cooling air to the cooling passage. Therefore, the cooling effect can be further improved.

It has a cooling fin 10a that connects the cooling passages 10, 10. These upper and lower tanks 8, 9, cooling passage 10, and cooling fins 10a are all made of aluminum. An aluminum water guide pipe 12 vertically passes through one side of the radiator 5 in parallel with the cooling passage 10. A cooling fin 10a is connected between the water guide pipe 12 and the adjacent cooling passage 10.

The upper end of the water guide pipe 12 made of aluminum opens into the upper tank 8 and communicates with the connecting pipe 14 so that a portion of the cooling water flows therethrough. One side of the cooling water separated at the upper end of the water guide pipe 12 is supplied to the upper tank 8 of the adjacent radiator via a connecting pipe 14 made of a rubber hose.

効果は著しく向上する。 According to the radiator device described above, the engine 11
The cooling water returned from the radiator 5 is transferred to the upper tank 8 of the radiator 5.
This is done by a water guide pipe 12 provided vertically penetrating inside the radiator 5 and a water guide pipe 13 from the engine 11 connected to the upper part of this water guide pipe 12. When cooling water is drawn out, it is carried out from the lower part of the radiators 5,5. Therefore, it is no longer necessary to provide a space on the back of the radiator 5 for routing the water pipe, and the radiator device can be made more compact. Also, radiator 5
Since there is no water guide pipe on the back of the cooling passage 10, the passage of cooling air to the cooling passage 10 is improved, promoting heat exchange in the cooling passage 10, and the water guide pipe 12 itself is also connected to the cooling passage 10 by a cooling fin 10a. The cooling effect is significantly improved because the cooling air is promoted.
また、導水パイプ１２がラジエタ５内部を貫通

The strength of the radiator 5 can be increased. Furthermore, by eliminating the need for installation space for a water guide pipe on the back of the radiator 5, the capacity of the fuel tank 17 is not sacrificed.
また、実施例のように導水パイプ１２、冷却通

The radiator does not occupy space at the back of the radiator, resulting in a compact configuration and increasing the strength of the radiator. In addition, a water guide pipe is installed inside the radiator in parallel with the cooling passage,
In addition, since the cooling passages are connected to each other with cooling fins, the water guide pipes do not obstruct the passage of cooling air to the cooling passages, and the water guide pipes themselves are also directly cooled by the cooling air, which increases the cooling effect. Further improvement can be achieved.
