Abstract

(57) [Summary] [Purpose] By providing an undercover for the engine room with a cooling function for the auxiliary equipment, good cooling performance of the auxiliary equipment can be maintained even when the opening space of the radiator grill is insufficient. [Structure] An undercover 30 located below auxiliary equipment such as a radiator 14 and a cooler condenser 16 provided in the engine room 10 of a vehicle has an air introduction portion 32 on the vehicle front side of these auxiliary equipment. However, air exhaust portions 34 are also formed on the vehicle rear side of the auxiliary equipment.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed for the radiator and cooler controller installed in the engine compartment of the vehicle. It is placed to protect auxiliary equipment such as power sensors from flying stones and water from the road side. This invention relates to an undercover for the engine compartment of a vehicle.

0002

[Conventional technology]

Generally, auxiliary equipment such as the radiator and cooler condenser are located at the front of the engine room. Air introduced from the outside through openings in the radiator grille and bumper located in It is designed to be cooled by air. However, depending on the car model, the radiator There may be insufficient space in the grille or bumper opening. In addition, the auxiliary equipment mentioned above The lower part of is covered with the undercover.

0003

[Problem that the idea aims to solve]

The undercover can protect auxiliary machinery from flying stones and water from the road surface, but it also This impairs the flow of air and reduces the cooling performance of the auxiliary equipment. and the aforementioned If the opening space for air introduction is insufficient as shown in the example above, cooling performance of auxiliary equipment may deteriorate. is a particular problem. The technical problem with this idea was that the undercover for the engine room had a protective device for auxiliary machinery. In addition to this function, by providing a cooling function for this auxiliary equipment, it is possible to open the radiator grill. To maintain good cooling performance of auxiliary equipment even when space is insufficient.

0004

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides an underbody for the engine compartment of a vehicle. The cover is constructed as follows. In other words, the radiator and cooler conditioner installed in the engine compartment of the vehicle. It is placed below the auxiliary equipment such as sensors to protect it from the road surface. The undercover has an air introduction part on the front side of the vehicle for the auxiliary equipment, and also an air introduction part for the auxiliary equipment. An air exhaust part is formed at the rear side of each type of vehicle.

[0005]

[Effect]

According to the above configuration, cooling is conducted into the engine room from the air introduction part of the undercover. Air is introduced. This air introduction part is located on the front side of the vehicle of the auxiliary equipment. Therefore, the air passes through these accessories while cooling them. and the sky after cooling the auxiliary equipment. The air is exhausted to the outside from the air exhaust part of the under cover on the rear side of the vehicle of this auxiliary equipment. Served. Of course, the undercover protects the auxiliary machinery from flying stones and water from the road surface. It is a matter of theory.

【Example】

Next, an embodiment of this invention will be described with reference to the drawings. FIG. 1 shows an overview of the interior of the engine compartment 10 of a vehicle in cross-sectional view, and FIG. 2 shows a front view of the vehicle. The front portion is shown in a perspective view. In these drawings, inside the engine room 10 Auxiliary equipment such as a radiator 14 and a cooler condenser 16 are provided. Note that the radiator 14 is mounted on the radiator support member 12 shown in FIG. supported on the surface. In addition, there is a radiator grill 1 on the front side of the engine compartment 10. 8 and bumper 20 are located, and from these openings 19 into the engine room 10 Air is now introduced.

[0007] Below the radiator 14 and cooler condenser 16, there is a An undercover 30 is provided to protect the vehicle from flying stones and muddy water. In other words, this undercover 30 covers the radiator support member 12 and other parts. Attach the bottom surface of the radiator 14 and cooler condenser 16 to a member (not shown). Fixed to cover.

[0008] The antenna on the front side of the vehicle of the radiator 14 and the cooler condenser 16 The edge of the cover 30 can be bent diagonally downward to form the fin 32a. has been completed. This fin 32a allows the undercover 30 and the bumper 20 to An air introduction section 32 for introducing external air into the engine room 10 is provided between the is configured. Also, an under cover on the rear side of the vehicle for the radiator 14 and cooler condenser 16. 30 includes a plurality of openings 34a penetrating inside and outside the engine room 10, and these openings 34a. The fin 34b is formed by bending the edge of the opening 34a on the rear side of the vehicle diagonally upward. Each is formed. These openings 34a and fins 34b An air exhaust section 34 is configured to exhaust air from inside the room 10 to the outside.

[0009] Now, due to the rotation of the fan (none of which is shown) accompanying the drive of the engine, the External cooling air (cool air) flows into the engine room 10 as shown by the arrow in Figure 1. The opening 19 between the radiator grille 18 and the bumper 20 and the under cover -30 are introduced from the air introduction portions 32, respectively. and engine room 1 The cool air that has entered the interior cools the radiator 14 and the cooler condenser 16. Passing by while avoiding. Air after cooling the radiator 14 and cooler condenser 16 (hot air) A) A part of the air discharge part 3 of the under cover 30 is shown as an arrow in FIG. 4 to the outside (lower part) of the engine room 10. In other words, this hot air is guided by each of the fins 34b constituting the air exhaust section 34, and each opening It is discharged to the outside through 34a. In this way, the air introduction portion of the undercover 30 into the engine room 10 Cool air is introduced from 32, and the air exhaust part 34 of this undercover 30 The hot air is discharged to the outside from the radiator 14 and the cooler controller. The capacitor 16 is efficiently cooled.

[Effect of the idea]

As mentioned above, this idea uses an undercover for the engine room to protect the engine. Protect auxiliary equipment such as radiators and cooler condensers in the system from flying stones and water from the road. Not only does it provide protection, but the engine route can also be accessed from the air intake part of this undercover. The cooling air introduced into the system cools the auxiliary equipment, and this air is then transferred to the undercover. Air can be exhausted to the outside from the exhaust part, opening space such as a radiator grill. Even when there is a shortage, the cooling performance of auxiliary equipment can be maintained well.
