Abstract

(57) [Abstract] [Purpose] The objective is to improve the cooling performance of the oil cooler in industrial vehicles and reduce the number of cooler assembly steps. [Configuration] Oil cooler pipe 1b is shrouded 1d
And the fan 3 and the radiator 4 so that they can be arranged between the fan 3 and the radiator 4.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to the structure and arrangement of an oil cooler in an industrial vehicle.

[0002]

[Prior Art]

 Conventionally, the oil cooler is generally either built into the radiator for engine cooling water or installed separately from the radiator. FIG. 3 shows an example of a conventional arrangement in which an oil cooler a is installed on the leeward side of a fan d that blows against a radiator d. The shroud b is formed so as to enclose the fan c. FIG. 4 shows an example without a shroud because the oil cooler a is installed between the fan c and the radiator d.

[0003]

[Issues that the device tries to explain]

 When the radiator is built-in with the above conventional structure, it is cooled by the engine cooling water that has become hot, so a large cooling effect cannot be obtained when the temperature difference is small. In addition, if it is installed separately from the radiator, the air to be cooled is heated because it has passed through the radiator once, and is not suitable when the vehicle wants to prioritize the temperature of the oil to cool it. If installed in between, the cooler interferes with the installation of the shroud, and the air from the fan escapes, lowering the cooling performance.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned problems, and an oil cooler is configured integrally with a shroud and is installed between the fan and the radiator.

[0005]

[Action]

 Since this invention adopts the configuration described above, it is possible to improve the cooling performance of the oil cooler and reduce the number of assembly steps.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of a shroud-integrated oil cooler 1. The pipe 1b of the oil cooler 1 is fixed to the shroud 1d by the fixing plate 1c, the oil inlet 5 and the oil outlet 6 are arranged on the side surface, and the mounting plate 1a is provided on the upper part of the shroud 1d to connect to the radiator 4. Fixing is convenient. FIG. 2 shows a side view of the shroud-integrated oil cooler 1 mounted between the fan 3 and the radiator 4, which is compactly fixed to the radiator 4 by three mounting bolts 2.

[0007]

[Effect of the device]

 As described in detail above, this invention has an oil cooler integrated with the shroud and installed between the fan and the radiator, so that the oil cooling performance is improved and the cooler assembly man-hours can be reduced. And will contribute to cost reduction.
