Abstract

PURPOSE:To suppress the temperature of a computer from increasing by setting the computer stored in a case in the intake pipe of an engine, and taking out only the harness of the computer from the intake pipe to the outside. CONSTITUTION:A computer 3 stored in a case 2 is set in the intake pipe 1 of an engine. Only the harness 4 of the computer 3 is arranged to protrude outward from the intake pipe 1 outside. A sealing tape 7 and a gasket 8 are wound/interposed around/in the taking-out port 5 of the harness 4 of the intake pipe 1/an intake pipe cover 6 for storing the computer 3 so as to prevent generation of air leakage. The case 2 of the computer 3 is fixed by means of the bolt 9 and the like of the intake pipe cover 6 for storing the computer 3, while sandwiching the gasket 8. The case 2 of the computer 3 is contacted with air which flows in the intake pipe 1 so as to cool the computer 3' itself. It is thus possible to suppress the temperature rise of the computer 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reducing the influence of heat from an engine on a computer mounted on a vehicle and used for various electronic controls such as fuel injection.

[0002]

2. Description of the Related Art Conventionally, an engine control computer mounted on a vehicle is mounted in a cabin that is not easily affected by heat of the engine, so that the engine mounted on the vehicle is used as a ship power source or a factory power source. In this case, it is difficult to use it as an integrated body with the engine, and there are problems that reliability is deteriorated due to many connectors and wiring.

[0003]

SUMMARY OF THE INVENTION According to the present invention, the computer is constructed integrally with the engine, so that the use of the computer can be expanded and the connector and wiring can be simplified. It seeks to provide a way to make it less susceptible to the heat of the engine.

[0004]

That is, in the invention of claim 1, the computer housed in the case is installed in the intake pipe of the engine, and only the harness of the computer is set in the intake pipe. A method for cooling a computer mounted on an engine, characterized in that the temperature of the computer is restrained from rising by using air flowing in the intake pipe. Is. In the invention of claim 2, the computer housed in the case is arranged along the intake pipe of the engine, and the case is provided.
In the engine, a heat radiator integrated with a gas is made to rush into the intake pipe, and the temperature of the computer is lowered through the heat radiator by utilizing the air flowing in the intake pipe. This is to propose a method for cooling the mounted computer.

[0005]

According to the method of the present invention, the computer itself housed in the case is installed in the intake pipe so that only the harness exits from the intake pipe.
The air is cooled by the air flowing in the intake pipe.

According to the second aspect of the present invention, a radiator, which is integrated with the case of the computer provided along the intake pipe, projects into the intake pipe, and the air flowing in the intake pipe is used. Then, by cooling the radiator, the temperature rise of the computer is suppressed.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings. First, in FIG. 1, reference numeral 1 denotes an intake pipe, and a space for installing a computer 3 housed in a case 2 is provided in the intake pipe 1, and a harness of the computer 3 is provided. It is arranged so that only 4 goes out from the intake pipe 1.

At this time, a seat is provided on the outlet 5 of the harness 4 of the intake pipe 1 and the intake pipe cover 6 for storing the computer.
By winding or interposing the sealing tape 7 and the gasket 8 as a sealing material, air leakage is prevented from occurring, and the casing of the computer 3 is sandwiched with the gasket 8 interposed therebetween.
The screw 2 is fixed to the intake pipe cover 6 for storing the computer with a bolt 9 or the like.

As described above, the case of the computer 3
By touching the air flowing through the intake pipe 1, the space 2 also cools the computer 3 itself.

Next, in FIG. 2, reference numeral 11 denotes an intake pipe, and a computer 13 housed in a case 12 is arranged along the intake pipe 11, and its mode is as follows: The casing 12 is attached to the computer mounting station 14 formed in FIG. 1 via a bolt nut 15.
Fixed to 1.

A heat radiator 16 is formed integrally with the case 12 and the heat radiator 16 is projected into the intake pipe 11 through a through hole 17 formed in the intake pipe 11. At this time, a seal material 18 such as a seal ring for preventing air leakage is interposed between the through hole 17 and the radiator 16.

The radiator 16 is shown as a plate in FIG. 2, but it may be in any shape such as a pipe as long as it can efficiently dissipate heat. In the figure, 19 indicates a harness.

In the structure shown in FIG. 2, since the radiator 16 is cooled by the air flowing in the intake pipe 11, the radiator 12 is cooled by the case 12 of the computer 13 integrated with the radiator 16. The temperature of the printer 13 itself can be prevented from rising.

[0014]

According to the invention of claim 1, since the computer itself is installed in the intake pipe, the heat radiation effect is extremely good,
Further, since the computer is protected by the intake pipe, there is an advantage that it is not mechanically damaged. The invention according to claim 2 is a computer through a radiator.
This has the effect that the function of suppressing the temperature rise of the computer can be adopted by slightly modifying the existing equipment. Further, when the vehicle-mounted computer control engine is used for a ship, a power source for a factory, etc., there is an advantage that the use as an integral part of the engine can be easily expanded. .
