Description

[Detailed Description of the Invention] The present invention relates to a cooling structure applied to an internal combustion engine chamber of a vehicle such as an automobile.

Conventionally, in this type of cooling structure, as shown in FIG. 1, a duct 3 is attached to the inside of the engine hood 2 of the internal combustion engine chamber 1, and the front end 3A of the duct 3 is opened to the rear of the upper edge of the front grille 4. 3B is opened at a predetermined position in the internal combustion engine chamber 1. In the figure, 5 is the front bumper.

In the above conventional configuration, the duct-like cooling structure is installed inside the engine hood, so the front end opening of the cooling structure is located behind the upper edge of the front grille.
That is, it is located near the rear of the boundary between the front grill and the engine hood. If the front end opening of the cooling structure is located in this position, the upper edge of the front grille will get in the way, and in order to make the duct shape follow the curved inner shape of the engine hood, the front end of the cooling structure should face diagonally downward or straight down. Since it is open, the air intake efficiency is extremely poor as shown by the arrow in Figure 1.

The present invention aims to improve the air intake efficiency in the cooling structure of the internal combustion engine compartment by improving the above-mentioned conventional drawbacks.
It consists of an intake duct whose front end opens behind the front grille, and a conduction duct that is attached to the inside of the engine hood and whose rear end opens at a predetermined position in the internal combustion engine chamber, and the rear end of the intake duct is connected to the front end of the conduction duct. The main idea is to connect them in a detachable manner.

The present invention will be explained with reference to an embodiment shown in FIG.
This is an internal combustion engine room containing an engine 7, etc., and is surrounded by an engine hood 12 and a front grill 14, and a front bumper 15 is attached to the lower part of the front grill 14. The cooling structure 13 consists of an intake duct 131 and a conduction duct 132, and the intake duct 131 is connected to the front grill 14.
It is attached to the rear via a bracket 14A, and the front end 131A is open to the rear of the central portion of the front grill 14. On the other hand, the conduction duct 132 is attached to the inside of the engine hood 12 via a bracket 12A, and its rear end 132B opens downward at a predetermined position in the internal combustion engine chamber 11. When the engine hood 12 is closed (solid line in Figure 3), the rear end 131B of the intake duct 131 is connected to the conduction duct 1.
Connect to the front end 132A of engine hood 1
2 (dotted line in Figure 3), the intake duct 131 and the conduction duct 132 are naturally separated. Note that the rear end 131B of the intake duct 131 and the conduction duct 132
Packings 181 and 182 are attached to the connecting portion with the front end 132A to provide airtightness.

Since the present invention has the above-mentioned configuration, the front end of the intake duct is opened toward the rear of the center of the front grille in the direction of vehicle travel, so that when the vehicle is running, air can be taken into the intake duct without any hindrance, and air can be taken into the intake duct and separated from the intake duct. A conduction duct that can be freely connected and conducts the air taken in from the intake duct to a predetermined position in the internal combustion engine chamber as shown by the arrow in Figure 3 is installed inside the engine hood, and when the engine hood is opened, it is natural that the It is located on the side and does not get in the way of inspecting the internal combustion engine room. Thus, the cooling structure of the present invention has significantly improved air intake efficiency compared to the conventional cooling structure.
