Intercoolers And Superchargers

January 10th, 2011 | Category: ENGINE, Superchargers and Blowers

You can think of an intercooler as a heat sink that cools the compressed air (responsible drinking) that pumps boost in the intake manifold. There may be two types of intercoolers on the market – air to air charge air and water, but despite that the water-air intercoolers work wonders on very short runways and are ideal for car slides are not practical on the street – and the type of car endurance racing. For trams and the type of drag racing to use an air-air.

Like the auto turbo, intercooler performance is not in it self  but is a crucial and important in the supercharged engine keeps the engine reliability. Its main purpose is to cool the intake charge. By reducing the temperature of the intake charge has two advantages:  it makes it more dense charge of air intake and denser produces more power because it has more air molecules per cubic inch, and reduces the possibility of detonation. Unfortunately, the intercooler is one major disadvantage: it is a barrier to access to the path and the corresponding reduction of the boost pressure! Unfortunately, there is no way around this problem, and the intercooler performance is much bigger than this side. The best thing you can do is to maximize efficiency and minimize the intercooler pressure drop caused by it.

To minimize the pressure drop caused by the intercooler to design an efficient intercooler to keep the pressure loss, at least. First, you must use the disc and core-shell instead of the extruder as the pot-core and core-shell offers less resistance to airflow. Secondly, the internal flow area of the nucleus has a significant impact on the loss of pressure. That’s why you should choose the right area intercooler internal flow to maintain the pressure, at least. The following chart is an excellent tool for evaluating the necessary internal flow based on its territory turbocharger flow.

As you can see from the chart, a compressor that produces a flow of 300 cfm require an internal power box about 15 meters after you have estimated the internal flow area of your compressor requires you to specify the size base you need to. This can be a bit tricky, since only about 45% of the intake charge comes into contact with heat exchange elements in the heat exchanger core. Therefore, you must first divide the internal flow area required by 45% and then divide the result of the base layer. This gives us the following formula:

internal flow area ÷ 0.45

thick base

Third, you must remember that each subsequent inch thick base is 40% less effective than previously empty, since the temperature of the air flowing through it increases as it draws heat from the load admission. Thus, the use of an intercooler with a thinner core, but a larger area fontal be more effective than a thick intercooler with a smaller frontal area.

Fourth, you can also improve the cooling efficiency of your broker, set up a chain to the front surface to force ambient air through the core. Without a channel, about 25% of the ambient air passes through the center and the rest will follow the path of least resistance around the nucleus. With a more efficient intercooler, you can increase the growing pressure to compensate for the loss of pressure caused by the intercooler.
