The intercooler is an integral part of the turbocharged engine system. The intercooler acts as a cooler for the air flow passing through the boost and acts as a heat exchange system. That is, the intercooler sucks warm air from the air stream that comes from the compression.

There are now several types of intercoolers for diesel engines, which have different heat transfer characteristics. However, in the production of intercoolers, the main criteria are the indicators of maximum heat removal, increased inertia of the air flow, as well as the minimum pressure loss of the turbine itself.

The intercooler functionality

The VALEO brand Intercooler, charger in a car engine works like a conventional radiator, which acts as an intermediary between the intake manifold and the turbine.

Accordingly, a high-quality intercooler is the device that is able to most effectively remove the heat that occurs when heated in a turbocharger. The potential, as well as the size of the intercooler system, as a rule, differs depending on the type of engine and power, which ranges from 300 to 750 horsepower.

As a rule, an increase in the area of ​​the plates that make up the intercooler leads to an increase in the capabilities of this system, but in practice everything is not so proportional.
