Description

[Detailed Description of the Invention] <Industrial Field of Application> The disclosed technology belongs to the field of technology that allows cooling air to be introduced efficiently and reliably into the radiator of an automobile during high-speed driving.

<Summary> This invention relates to a radiator cooling air duct in which a forced air duct is formed by a deflector in the cooling air intake space from the front grill of an automobile to the radiator. From both sides of the radiator to the front grill mounting place, etc., the front grill is laterally blocked by vertical deflectors on both sides, and an engine under cover is extended below the side deflectors to serve as a bottom deflector. This invention relates to a radiator cooling air duct in which the lower part is blocked off, and the upper part is covered and surrounded by a reinforcing plate of the hood inner to form a closed-section passage exclusively for introducing cooling air.

<Prior art> As is well known, a radiator for circulating cooling water as a cooling mechanism for an automobile engine is installed in front of the engine and behind the front grill, so that the engine is air-cooled by air taken in from the front grill when the vehicle is running. .

<Problem that the invention aims to solve> However, recently, double type headlamps, headlamp cleaner equipment, cooler-related equipment, etc. have been concentrated in the front part of the engine room, so radiators is separated from the front grill by design and is installed through the cooling air intake space. Therefore, there is a disadvantage that when driving at high speed, the cooling air taken in from the front grill is easily diffused in the cooling air intake space, reducing the cooling efficiency.

Further, the front fins attached to the radiator significantly increase the wind guiding resistance at high speeds, which also has the disadvantage of making it easy to bypass the cooling air from the cooling air intake zone to the sides.

In addition, due to the development of expressways and the informationization of traffic, there is a tendency for vehicles to travel at higher speeds, and therefore, the above-mentioned disadvantage has been associated with the reverse development of a reduction in the cooling capacity of the radiator during high-speed driving.

For example, it is disclosed in Japanese Utility Model Application Publication No. 51-79821.
Some designs have been devised that look like an air duct is formed from the front grill to the radiator, but there is no upper cover shield plate at the bottom of the hood, which tends to cause air leaks, and it is difficult to open the hood. Sometimes, the bulkhead gets in the way, making maintenance and inspection difficult.

The purpose of this invention was to solve the technical problem of high-speed air guide for automobile radiators based on the above-mentioned conventional technology, and to provide an air guide path from the front grille to the radiator that is isolated from the engine room. It is an object of the present invention to provide an excellent radiator cooling air duct which is beneficial to the field of cooling technology application in the automobile industry by preventing bypass of cooling air without degrading the radiator cooling performance.

<Means/actions for solving the problem> In accordance with the above-mentioned purpose, the structure of this invention, which is summarized in the claims of the above-mentioned utility model registration, is to solve the above-mentioned problem by installing the radiator from the mounting places on both sides of the front grill. Vertical deflectors are installed on both sides to prevent cooling air from bypassing to the sides, and an engine under cover is installed at the bottom to act as a bottom deflector to prevent cooling air from escaping downward. The hood reinforcement plate I covers the upper part to prevent upward flow and force cooling air into the radiator. Air duct inspections can be easily performed by opening the hood, and various equipment can be wired. The piping is the result of technical measures that have enabled the use of air duct deflectors as mounting surfaces.

<Example - Configuration>.

Next, one embodiment of this invention will be described below based on the drawings.

The illustrated part is the front part of a car, and a front grill 2 of an appropriate form is arranged in the upper center of a bumper 1, and double-type headlamps 3.3 are arranged on both sides.
□A hood 5 with a hood inner 4 as a reinforcing plate integrally provided inside is provided facing above.

Further, a well-known radiator 7 is attached to the back of the front cross member 6 via radiator supports 8, 8, and an engine under cover 9 is provided at the rear of the front cross member 6, extending downward from the bumper 1. An engine undercover 9 is extended and connected to the balance panel 10 as a bottom deflector 11 to block cooling air from escaping downward.

Then, the headlamp mounting places 12° 12 on the inside of the headlamps 3.3 on both sides of the front grille 2 are set in the backward position and fixed to the pair of left and right side deflectors 13.13, attached and connected to both sides of the radiator 7, and attached to the bottom surface. It is designed to be integrated with the deflector 11 by appropriate means such as flange connection to provide side shielding.

In addition, 14 is a blade, which is moved forward and backward from the upper edge of the radiator 7 to cover the cover, and has deflectors 13 on both sides.
．． 13, and the hood inner 4 of the hood 5 covers the upper ends of both side deflectors 13, 13 in the form of a bridge when the hood is closed.
The cooling air duct 15 is formed so as to reach the blade 14, so that the section from the front grill 2 to the radiator 7 has a rectangular cross section, and the periphery is blocked off to form a cooling air duct 15.

<Embodiment - Effect> In the above-described configuration, when the hood 5 is closed, the air duct 15 formed acts as a tunnel-shaped air guide path, and a fan (not shown) sucks air when the vehicle is stopped, at medium speed, or at low speed. Not only the relative suction air, but also the cooling air to the radiator 7 during high-speed driving is introduced from the front grille 2 as shown by the arrow, and is reliably supplied without flowing into the surrounding area. Therefore, the radiator 7 is designed It can perform a street cooling effect.

For inspection etc. inside the air duct 15, please refer to the hood 5.
By opening the hood, the reinforcing plate 4 of the hood inner opens together with the hood, allowing a predetermined work to be performed freely.

In addition, various equipment in the engine room, such as the cooler box, its pipes, headlamp cleaner bosses, cooling tubes, etc., are attached and connected by using the deflector 13° 13.11 and the blade 14 of the air duct 15 formed as described above. You can use it as you see fit.

Of course, depending on the design, the tip opening of the intake nose of the air cleaner can be opened to face the inside of the air duct 15.

It goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment. For example, the bottom deflector may be slid through a lever as appropriate to suck in outside air from below while the vehicle is stopped or at low speed. In order to introduce cooling air,
Numerous aspects can be adopted such as closing at high speed.

<Effects of the invention> As described above, according to this invention, in the cooling air duct provided in the cooling air intake space from the front grille to the radiator of an automobile, a vertical deflector is provided from both side edges of the radiator to the inside of the headlamp. A low surface deflector is provided at the lower edge of the deflector on both sides that move forward and backward, and a reinforcing plate for the hood inner is installed to automatically cross over the deflectors on both sides when the hood is closed, thereby creating an air duct with a closed section. By forming the radiator, the cooling air introduced from the front grill during high-speed driving is basically supplied to the radiator without escaping to the outside of the air duct, and therefore the resistance of the radiator fins is Nevertheless, an excellent effect is achieved in that the cooling air can forcibly provide a cooling effect in a kind of forced-feeding state.

In addition, the air duct deflector can be used by extending the mounting places for headlamps, front grilles, etc., and the engine under cover can be extended and the hood inner can be used, so it is necessary to use a special duct plate. On the contrary, it has advantages such as being able to be used as a mounting part for cooler hoses, headlamp cleaner bosses, etc.

Furthermore, the bottom deflector, together with the balance panel, can further improve the aerodynamic characteristics of the automobile, and wiring the ignition circuit using the air duct can also help prevent theft of the automobile.

A reinforcing plate integrated into the hood inside the hood automatically forms the top cover of the air duct when the hood is closed, ensuring a closed section of the duct up to the radiator.
Moreover, since the upper part of the air duct is opened when the hood is opened, various maintenance inspections can be easily carried out.
