Description

Intercooler duct of a car

The present invention relates to an intercooler duct of a motor vehicle. More specifically, the present invention relates to an intercooler duct of a motor vehicle that can improve the efficiency of an intercooler by improving the structure of the intercooler duct to increase the volume efficiency of the running wind.

In general, the turbocharger is equipped with an intercooler to improve the engine performance by improving the volumetric efficiency by cooling the compressed high intake running wind temperature passing through the intercooler with the driving wind of the vehicle. When the intercooler is mounted, the driving wind flows from the outside of the vehicle to the intercooler through a separate duct (flow path), and a flow path is formed in two ways as shown in FIGS. 1A and 1B.

First, as illustrated in FIG. 1A, a driving wind suction duct 100 ′ may be formed at the center of a vehicle hood 22 ′, and an intercooler 26 ′ may be mounted below the duct 100 ′. Of course, the engine 28 'is located under the intercooler 26'.

In this case, the driving wind is directly injected into the intercooler 26 'through the duct 100' in the center of the hood 22 ', and the driving wind is mainly concentrated toward the rear of the intercooler 26' while driving the vehicle. . In the figure, reference numeral 30 'is a radiator grille.

In addition, a separate long duct 100 'may be installed from the radiator grill 30' to the intercooler 26 'as shown in FIG. 1B. That is, the duct 100 'is installed to extend from the radiator grill 30' which is the lower surface of the body hood 22 'to the intercooler 26', and the duct 100 'and the intercooler 26' are approximately Are coupled in parallel.

In this case, the running wind is injected into the duct 100 'through the radiator grill 30' and the running wind guide duct 24 ', and the running wind passing through the duct 100' is an intercooler ( 26 ') directly in the top. Here, the driving wind is mainly concentrated toward the rear of the intercooler 26 'while the vehicle is running.

However, these two conventional methods have disadvantages in that the intercooler is mounted almost parallel to the driving wind, and the flow path of the driving wind is short and has a straight structure.

That is, the running wind flowing into the intercooler is concentrated at the rear of the intercooler, which not only reduces the volume efficiency of the running wind, but also reduces the efficiency of the intercooler.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide an intercooler duct of a vehicle that can improve the volume efficiency of the running wind by improving the structure of the intercooler duct.

Another object of the present invention is to provide an intercooler duct of a vehicle which can increase the cooling efficiency of the intercooler by increasing the airtightness of the running wind inlet and outlet of the intercooler duct.
