Description

[Detailed explanation of the idea] The present invention relates to a radiator for a vehicle.

Conventionally, in some vehicles, in addition to an engine cooling radiator, a radiator for use in an aftercooler for cooling a turbo supercharger, a transmission oil cooler, a car cooler condenser, etc., is placed before and after the engine cooling radiator. There are cases where

In this case, with conventional radiators, for example, the piping hose of the radiator placed at the front was installed by bypassing the outside of the radiator at the rear, which resulted in the hose becoming longer and the necessary space being secured for this purpose. Therefore, the vehicle layout becomes inflexible.

The present invention has been developed in view of the conventional situation, and has a configuration in which a through hole is formed in the tank portion of one radiator in the longitudinal direction of the vehicle, and a pipe for attaching the cooling water hose of the other radiator is passed through it. An object of the present invention is to provide a radiator for a vehicle that allows flexibility in vehicle layout.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIGS. 1 and 2, numeral 1 denotes a radiator composed of three parts: an upper tank 2, a lower tank 3, and a core 4.

Further, the upper tank 2 is provided with a cap 5, an inlet vibro, etc., and the lower tank 3 is provided with an outlet pipe 7.

Although not shown in the drawings, the core 4 is provided with a large number of tubes and radiation fins that communicate the upper tank 2 and the lower tank 3.

Reference numeral 8°9 denotes through holes formed in the upper tank 2 and lower tank 3, which are penetrated in the longitudinal direction of the vehicle when the radiator 1 is mounted on the vehicle. sleeve 1 to prevent leakage.
6 is inserted and fixed.

When a vehicle radiator with such a configuration is mounted on a vehicle,
An aftercooler for cooling a turbo supercharger or an oil cooler for an I-transmission installed separately from this radiator 1,
A radiator used for a car cooler condenser or the like may be arranged as shown in the first figure.

That is, another radiator 10 is installed in front of the radiator 1 having a through hole, and the inlet pipe 11 of the radiator 10 is inserted into the through holes 8 and 9. The outlet pipes 12 are passed through the second
Connect the hose 13 to its tip as shown in the figure.

Note that FIG. 2 shows only the inlet pipe 11 side.

Therefore, the hose 13 connected to the pipes 11, 12 can be shorter than in the past, and the effective space can be expanded accordingly, increasing the flexibility of vehicle layout.

Although FIG. 1 only shows an example in which another radiator 10 is installed before the radiator 1 having a through hole, the same effect can be obtained even if the other radiator 10 is installed later.

Also, as shown in Fig. 3, the inlet pipe 1 of the heat sink 10
A separate pipe 14 may be passed through the through hole 8, and the inlet pipe 11 and the pipe 14 may be communicated via a hose 15. In this case, the flexibility of the vehicle layout is further increased.

Although only the inlet pipe 11 side is shown in FIG. 3, it goes without saying that the same applies to the outlet pipe 12 side.

The same applies to the case where the radiator tanks are located on the left and right sides.

Alternatively, the tank including the through hole may be integrally molded without inserting the sleeve.

As described above, according to the present invention, flexibility in vehicle layout can be greatly improved.

Further, the connecting hoses of the radiators placed in front or behind the radiator provided with the through holes can be shortened, and the number of connection points between the hoses can be reduced, which is effective as a measure to prevent leakage.

Furthermore, by shortening the hose, the effective space can be expanded, the weight can be reduced, and the cost can be reduced, and the piping installation work can be made extremely easy.
