Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a radiator for a two-wheeled vehicle, and particularly relates to a radiator in which a main body frame 9 and an inlet pipe 6 of a tank 4 are arranged close to each other.

[Prior art]

The mounting space for a radiator mounted on a two-wheeled vehicle is extremely narrow, and it is generally located just in front of the engine and directly below the leading end of the frame. Engine cooling water flows into the upper part of the inlet tank and returns to the engine from the lower part of the outlet tank.

[Problem to be solved]

In such a motorcycle radiator, the rubber hose that connects the inlet pipe located at the top and the water jacket of the engine tends to come into contact with and interfere with the main body frame of the motorcycle. If the two interfere in this way, the rubber hose may be damaged and there is a risk of water leakage. Therefore, the arrangement of cooling water piping for conventional two-wheeled vehicles has been extremely troublesome. In particular, in order to distribute a certain amount of cooling water, a relatively thick rubber hose must be used.
Because of this, the rubber hose has poor flexibility and a large outer diameter, so it tends to interfere with the main body frame.

[Means for solving problems]

Therefore, the present invention adopts the following configuration in order to eliminate the above problems.

That is, the core 3 is constructed by disposing the fins 2 between a plurality of tubes 1 arranged in parallel. An inlet tank 4 and an outlet tank 5 are provided in which both ends of the tube 1 communicate with each other, an inlet pipe 6 is protruded from the upper outer surface of the inlet tank 4, and an outlet pipe 7 is provided on the outer surface of the outlet tank 5. and the inlet pipe 6,
The outlet pipe 7 and the engine water jacket are communicated with hoses 8 and 11, respectively. The main body frame 9 of the two-wheeled vehicle is located only near the inlet pipe 6 of the hose 11. Here, the feature of the present invention is that two short, thin inlet pipes 6 are arranged in parallel at the upper part of the inlet tank 4. and each inlet pipe 6
One end of a thin hose 11 is connected to each of the two ends. A thick outlet pipe 7 is protruded from the outlet pipe 5, and a thick hose 8 is connected to the outlet pipe 7. The hose 11 of the inlet pipe 6 has greater flexibility than the hose 8 of the outlet pipe 7.

Therefore, according to the present radiator, since the hose 11 is relatively thin, even if it comes close to the main body frame 9, there is a margin and interference between the two can be avoided. Furthermore, since the thinner hose 11 has greater flexibility, it is easier to guide it in a direction to avoid interference with the frame. In addition, even if the main body frame 9 and the hose 11 come into contact with each other due to vibration or the like, they are easily deformed and the connecting portion of the hose can be protected. This prevents water leakage from the radiator, which can cause engine trouble, and provides a highly reliable radiator. Furthermore, although two thin hoses 11 are used, there is no risk of increasing the flow resistance of the engine cooling water, and the heat dissipation of the radiator can be ensured.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings. FIG. 1 is a schematic perspective view of the main parts of the radiator of the present invention. FIG. 2 is a plan view thereof. The main body frame 9 of this embodiment has a main part formed in a U-shape, and a plurality of branches integrally extending downward from the main part. The main part of the main body frame 9 is arranged so as to be inclined downward from the front to the rear of the two-wheeled vehicle. A core 3 is disposed directly below the tip of the main body frame 9 and immediately in front of the engine 10 so as to be inclined backward. As shown in FIG. 2, this core 3 has a large number of parallel tubes 1 and a large number of fins 2 located between them, and both ends of each tube 1 communicate with an inlet tank 4 and an outlet tank 5. However, the communication portion is fixed by brazing. A pair of relatively thin inlet pipes 6 are provided at the upper part of the inlet tank 4. A relatively thick pipe 7 is provided at the bottom of the outlet tank 5. Hoses 8 and 11 having inner diameters matching the outer diameters are attached to the inlet pipes 6 and outlet pipes 7, respectively. The pair of inlet pipes 6 are each provided with one end of a pair of thin hoses 11, and the other end is connected to an engine 10.
are respectively connected to the outlet side of the water jacket. Further, one end of a thick hose 8 is connected to the outlet pipe 7, and the other end is connected to the inlet side of the water jacket of the engine 10. Both hoses 8 and 11 have the same material and structure. Therefore, the thinner hose 11 necessarily has greater flexibility than the thicker hose 8. As a result, in this embodiment, the hose 11 connected to the inlet pipe 6 closest to the main frame 9
is relatively thin, so the main body frame 9 and hose 11
A margin is created between the two, and interference between the two can be prevented. Furthermore, since the hose 11 is highly flexible, it is easy to guide it in a direction where it does not interfere with the frame 9. In addition, even if the hose comes into contact with the frame due to vibration or the like, there is no risk of the hose being easily deformed and damaging the pipe connection portion. Further, since the outlet pipe 7 is located at the lower part of the outlet tank 5 and is relatively far away from the main body frame 9, even if a thick hose 8 is used, it will not interfere with the main body frame 9.

[Effect of idea]

The two-wheeled vehicle radiator of the present invention has the above-mentioned configuration and has the following effects.

This radiator has a main body frame 9 located close to the inlet pipe 6 of a thin hose 11, and two thin inlet pipes 6 are arranged in parallel above the inlet tank 4, and each inlet pipe is 6 is connected to the ends of a pair of thin hoses 11, there is a margin between the hoses 11 and the main body frame 9, which prevents interference between the two and prevents damage to the hoses 11 due to such interference. do,
To prevent radiator water leakage accidents.

Furthermore, the thinner hose 11 has greater flexibility and can be guided in a direction that does not interfere with the frame.
In addition, even if the hose comes into contact with the frame due to vibration or the like, there is no risk of the hose being easily deformed and damaging the pipe connection portion of the hose. Therefore, a highly reliable radiator can be provided. Moreover, although the present invention uses thin hoses 11, two of them are connected to the inlet tank 4, so the core 3
This prevents a decrease in the flow rate of cooling water inside the tank and maintains heat exchange performance.
