Abstract

PURPOSE:To reduce the projected part of an outlet pipe in the width direction of a car body, by forming an outlet passage in a tank on the outlet side. CONSTITUTION:An outlet port 26a is opened nearly in the middle part of a tank 20 on the outlet side. By opening the port 26a in this position, cooling water being fed from one cylinder 15a of an engine via an inlet pipe 19a and that being fed from another cylinder 15b via an inlet pipe 19b can be cooled being well balanced. Besides the projected part of an outlet pipe 28 in the width direction of a car body is reduced by forming an outlet path 26 for cooling water in the tank 20 on the outlet side. The radiating surface is increased by expanding the surface of a radiator core 18, so that cooling efficiency of a radiator can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radiator for a vehicle that cools a water-cooled engine of a motorcycle or the like.

[Conventional technology]

Some radiators for vehicles such as motorcycles equipped with a water-cooled engine include a cooling water inlet tank and a cooling water outlet tank on both sides of the radiator core, and are arranged in the left-right direction of the vehicle body between the engine and the front wheels. When this type of radiator is equipped with a multi-cylinder engine, engine cooling water is introduced from the cooling water introduction pipes installed at the top and bottom of the inlet side tank, cooled by the central radiator core, and cooled by the side wall of the delivery side tank. There is one in which a delivery pipe is connected approximately in the center and the delivery pipe is piped along the side wall of the delivery side tank.

[Problem that the invention seeks to solve]

However, with such a structure, the delivery pipe protrudes in the width direction of the vehicle body, and due to space constraints due to the routing of the delivery pipe, the area of the radiator core becomes narrow and the length of the delivery pipe becomes long. There were other problems.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a radiator in which the area of the radiator core is increased by reducing the protrusion and length of the delivery tube.

[Means for solving problems]

To achieve the above object, the present invention provides a radiator for a vehicle having a cooling water inlet tank and a delivery tank on both sides of a radiator core, in which cooling water inlet pipes are provided at the upper and lower parts of the inlet tank. , a partition wall extending from approximately the center to the lower part is provided in the delivery side tank to form a cooling water delivery path between it and the tank side wall, and a cooling water delivery pipe is connected to the lower part of the delivery path. It is said that

[For production]

With this configuration, the delivery path can be formed in the delivery side tank, the protrusion of the delivery pipe in the vehicle body width direction can be reduced, and the length of the delivery pipe can be shortened.

(Example) An embodiment of the present invention will be described below based on the drawings.

The motorcycle 1 has a main frame 2 consisting of a cylindrical body having a rectangular cross section with a large vertical width, arranged on both sides of the vehicle body, the tip of which is connected to a head vibrator 3, and the connected part is reinforced with a head vibrator gusset 4. Pivot plate 5 on the incised end
A seat rail 6 is connected to the upper surface of the intermediate portion, and an engine hanger 7 is connected to the lower portion of the intermediate portion.

The head vibe 3 is rotatably provided with a front fork 9 that supports a front wheel 8, and is movable using a handlebar 10.

The pivot plate 5 is integrally provided with a seat gusset plate 11 at its upper end, and supports the seat rail 6 by connecting the upper end of the seat gusset plate 11 to the intermediate part of the seat rail 6, and has a rear fork 12 at its lower part.
A rear wheel 13 is supported at the tip of the rear fork 12, and a rear suspension device 14 is provided between the rear fork 12 and the upper part of the seat gusset plate 11.
is provided.

The engine hanger 7 has a vertical type engine 15.
is supported by the pivot plate 5, and in front of the engine 15, a radiator 16 is connected to the head vibe gusset 4 via mounting brackets 16a with an upper part provided on both sides thereof, and a radiator 16 with a lower part provided on both sides thereof. It is connected to the side of one cylinder body 15a of the engine 15 via a link rod 17 that is connected to a mounting bracket 16b.

The radiator 16 has a cooling water introduction tank 19 and a cooling water delivery tank 20 on both sides of the radiator core 18.
In the radiator core 18, water vibes 21 that connect an inlet side tank 19 and an outlet side tank 20 to flow cooling water are arranged in multiple stages parallel to the upper and lower edges, and each water vibe 2
Cooling fins 22 are disposed between the two.

In the introduction side tank 19, a cooling water introduction pipe 19a is connected to one cylinder body 15a of the engine 15 via a radiator hose 23 at the top thereof, and a cooling water introduction pipe 19a is connected to the other cylinder body 15b of the engine 15 via a radiator hose 24 to the bottom thereof. Cooling water introduction pipes 19b are respectively provided for connection.

A partition wall 25 extending from approximately the center to the lower part is provided in the delivery side tank 20, and a cooling water delivery path 26 is formed between the tank side wall 20a that bulges from the approximate center to the bottom. A delivery port 26a is opened approximately in the center thereof, and a delivery pipe 28 connected to the engine 15 via a radiator hose 27 is connected to the lower part of the delivery passage 26.

With this configuration, the outlet port 26a opens approximately in the center of the outlet tank 2o, so that the engine 1
5, the cooling water is introduced from one cylinder 15a through the introduction pipe 19a, and the other cylinder 15b is introduced from the introduction pipe 19.
The cooling water introduced through the tank 20 can be cooled in a well-balanced manner.
6, the protrusion of the delivery pipe 28 in the vehicle body width direction is reduced, and the area of the radiator core 18 is expanded to increase the heat dissipation area and improve cooling efficiency.

〔Effect of the invention〕

As described above, the present invention provides a radiator for a vehicle having a cooling water inlet tank and an outlet tank on both sides of a radiator core, in which cold water inlet pipes are provided at the upper and lower parts of the inlet tank. A partition wall extending from approximately the center to the bottom of the tank is provided in the delivery side tank to form a cooling water delivery path between the tank side wall and a cooling water delivery pipe is connected to the lower part of the delivery passage. The area of the radiator core can be expanded by reducing the protrusion of the radiator in the width direction of the vehicle body, improving cooling efficiency, and simplifying the delivery pipe piping, which is located on both sides of the rear of the radiator where it does not create resistance to the radiator exhaust air. can be piped to.
