[Industrial applications]

 The present invention relates to an outside air introduction structure of an intercooler, and particularly in an intercooler used for a supercharged engine of a vehicle, it prevents the outside air that has passed through the intercooler cover from escaping without being introduced into the intercooler, and the air amount The present invention relates to an outside air introduction structure of an intercooler that increases cooling performance to improve cooling performance.

[0002]

[Prior Art]

 The intercooler used in the supercharged engine introduces outside air from the outside air intake port of the air introduction part formed in the hood of the vehicle, and guides the outside air through the intercooler cover to cool the intake air. Is going.

As an outside air introduction structure of the intercooler, there is one disclosed in Japanese Utility Model Laid-Open No. 61-48818. The engine intercooler device disclosed in this publication is located below the outside air inlet provided in the hood and is installed with the intercooler mounted in a substantially horizontal state with respect to the engine. A cover member having an open end is attached.

Further, there is one disclosed in Japanese Utility Model Laid-Open No. 63-58029. The outside air introduction device for an air-cooled intercooler disclosed in this publication has an intercooler arranged substantially horizontally above the engine body, supports the intercooler by the engine body, and forms an outside air intake opening in the engine hood above the intercooler. In the case where the outside air is introduced into the engine hood, a flange is formed on either the inner wall surface of the engine hood around the outside air intake opening or the peripheral portion of the upper wall surface of the intercooler, extending over the entire circumference thereof and expanding outward. At the same time, the root portion of a flexible duct for guiding the introduction of the outside air is fixed to the other of them, and the flexible duct has a seal portion at its tip end portion capable of sealingly engaging with the inner wall surface of the flange. The flexible duct between the seal and the root has a bellows shape.

[0005]

[Problems to be solved by the device]

 By the way, in the conventional outside air introduction structure of the intercooler, as shown in FIG. 5, the outside air introduced from the outside air introduction port 112 of the air introduction portion 106 formed in the hood hood 102 of the vehicle (not shown) is introduced into the intercooler cover 108. While being guided to the intercooler 104 via the intercooler 104, the outside air introduced to the outside flows out from the gap S exposed between the air introduction part 106 and the intercooler cover 108, and the amount of the air flowing out to the outside is divided. However, there is an inconvenience that the amount of outside air introduced into the intercooler is reduced and the cooling performance is reduced.

[0006] Further, what was devised in order to eliminate this inconvenience is disclosed in the above-mentioned Japanese Utility Model Laid-Open No. 63-58029. In this publication, a bellows-shaped flexible duct for guiding the introduction of the outside air is provided at a location where the outside air flows out to prevent the outside air introduced by the flexible duct from flowing out. However, the outside air is reliably guided to the intercooler to improve the cooling performance of the intercooler.

However, when arranging the bellows-shaped flexible duct for guiding the outside air at a location where the outside air flows to the outside, the positioning of the flexible duct is very difficult, and the mounting work is difficult. In addition to being poor in performance, it is prone to errors and is disadvantageous in practical use.

Further, since the flexible duct for introducing the outside air is connected to the engine body by the root portion or the seal portion, the vibration or vibration of the engine is transmitted to the flexible duct, and the connecting portion is not worn. This may cause damage to the flexible duct, and if damaged, the adhesion will be impaired, and the amount of air will be reduced, leading to the disadvantage of reduced cooling performance.

[0009]

[Means for Solving the Problems]

 Therefore, in order to eliminate the above-mentioned inconvenience, the present invention provides an outside air introducing structure of an intercooler, which guides outside air introduced from an outside air inlet of an air introducing portion to an intercooler through an intercooler cover. At least a part is equipped with a sponge member for preventing the outside air introduced from the air introduction unit from escaping to the outside.

[0010]

[Action]

 By devising as described above, the outside air introduced from the outside air introduction port of the air introduction unit prevents the outside air from escaping to the outside by the sponge member, and reliably guides the outside air to the intercooler through the intercooler cover. The cooling capacity of the intercooler is improved by increasing the amount of air introduced into the intercooler.

[0011]

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. In FIG. 1, 2 is a hood of an engine (not shown) equipped with a supercharger (not shown), 4 is an intercooler, 6 is an air introduction part, and 8 is an intercooler cover.

An outside air introduction guide intercooler cover 8 is provided between the introduction port 10 of the intercooler 4 and the air introduction portion 6, and is sucked through the outside air introduction port 12 of the air introduction portion 6 formed in the hood 2 of the hood. The outside air is guided to the introduction port 10 of the intercooler 4 by the air introduction portion 6 and the outside air introduction guide intercooler cover 8.

At least a part of the intercooler cover 8 is provided with a sponge member 14 for preventing the outside air introduced from the air introducing portion 6 from escaping to the outside.

More specifically, at least a part of the intercooler cover 8, for example, a rear portion 8b of the intercooler cover 8 is provided with a sponge member 14 for a predetermined cooling performance having a spongy porous structure. The sponge member 14 is provided so as to fill the gap S between the air introducing portion 6 and the intercooler cover 8 at the time of attachment and the rear 8b portion so as to be in close contact.

Further, the sponge member 14 has a function of increasing the degree of adhesion between the air introducing portion 6 and the intercooler cover 8 by being highly stretchable.

Further, the sponge member 14 is formed in, for example, a quadrangular prism shape, and the sponge member 14 is mounted so that the longitudinal direction of the sponge member 14 is orthogonal to the longitudinal direction of the vehicle (not shown). A double-sided tape 16 is applied to the lower surface 14y of the sponge member 14 so as to fix it to the intercooler cover 8 as well as a coating for eliminating the above.

Next, the operation will be described.

While the vehicle (not shown) is running, as shown in FIG. 1, air is introduced from the outside air introduction port 12, and the outside air is guided to the outside air introduction intercooler cover 8 by the air introduction unit 6.

At this time, the outside air introduced into the outside air introduction guide intercooler cover 8 does not flow out of the intercooler 4 through the gap S between the air introduction portion 6 and the intercooler cover 8 by the sponge member 14. It is guided only to the inlet 10 side and introduced into the inlet 10 of the intercooler 4.

As a result, the sponge member 14 can surely prevent the outside air from flowing out, and the amount of air introduced from the inlet 10 of the intercooler 4 can be increased to improve the cooling performance of the intercooler 4. It is possible to improve engine performance, improve engine performance, and improve fuel efficiency, which is economically advantageous.

Further, since the sponge member 14 has a property of being highly stretchable, the sponge member 14 is resistant to vibration and wear of a supercharged engine (not shown) due to vibration and vibration, and is not likely to be damaged. Besides being advantageous, the sponge member 14 can be easily fixed to the intercooler cover 8 by the double-sided tape 16, and the workability of mounting is very good.

Furthermore, by fixing the sponge member 14 to the intercooler cover 8 using the double-sided tape 16, the peeling / replacement work at the time of maintenance / inspection of the sponge member 14 is easy and convenient.

Furthermore, since the positioning of the sponge member 14 is easier than that of the conventional one, the error can be reliably absorbed, and the structure of the outside air introducing structure is very simple, and the manufacturing is easy. Therefore, the cost can be kept low and it is economically advantageous.

FIG. 4 shows a second embodiment of the present invention. In the second embodiment, the parts having the same functions as those in the first embodiment will be described with the same reference numerals.

The feature of the second embodiment is that the sponge member 14 is fixed only to the rear 8b portion of the intercooler cover 8 in the first embodiment, but it is not limited to the rear 8b portion. The sponge member 20 is fixed to the entire circumference of the intercooler cover 8 except the front 8a, that is, the rear 8b and the left and right sides 8c and 8d.

That is, as shown in FIG. 4, the gap S between the air introducing portion 6 and the intercooler cover 8 is further filled by fixing the sponge member 20 to the rear 8b portion and the left and right sides 8c and 8d portions. Therefore, the cooling performance of the intercooler 4 is improved by further increasing the contact and introducing the outside air guided by the intercooler cover 8 after being introduced into the air introduction part 6 from the inlet 10 of the intercooler 4 without flowing out. Can be further increased.

Even if the sponge member 20 is fixed to the rear portion 8b and the left and right sides 8c and 8d, the structure of the outside air introducing structure is not significantly complicated, and the manufacturing is easy and the cost is kept low. It is possible and economically advantageous.

The present invention is not limited to the above-mentioned embodiment, and various application modifications are possible.

For example, in the first embodiment of the present invention, a coating is applied only to the front surface portion of the sponge member so as to eliminate air permeability. However, even if the coating is not applied, the amount of outside air introduced into the intercooler may be increased. There is a sufficient effect of increasing the amount of dust and absorbing dust when driving on rough roads, and it is not limited to coating and it is possible to coat not only the front surface of the sponge member but also the desired surface. .

Further, in the first embodiment of the present invention, the double-sided tape is used for fixing the sponge member to the intercooler cover, but an adhesive or the like may be used instead of the double-sided tape. is there.
