Among the heat exchangers, an intercooler is a device that cools the compressed air at high temperature and high pressure by the supercharger to increase engine output.

The air rapidly compressed by the supercharger has a very high temperature, expands the volume and decreases the oxygen density, resulting in a decrease in the filling efficiency in the cylinder. Accordingly, the intercooler cools the high-temperature air compressed in the supercharger, thereby increasing the intake efficiency of the engine cylinder and improving the combustion efficiency, thereby increasing fuel efficiency.

The intercooler in charge of this role can be divided into a water cooling type and an air cooling type according to the cooling method. Among these, the water-cooled intercooler is similar in principle to the air-cooled intercooler, but differs in that the compressed air is cooled using vehicle coolant or water instead of external air when cooling the intercooler through which high-temperature air passes.

The method of claim 1,
The pitch of the louver is, characterized in that 1.0 ~ 6.0mm, the heat exchanger.
The method of claim 1,
The pin is
a base plate formed on a surface in contact with the tube; and
Further comprising a connection plate connecting the ends of the plurality of louvers,
The louver is formed extending from the base plate, the heat exchanger.
The method of claim 1,
The louver is
A plurality are spaced apart,
