Heat exchangers to reduce the input
Although not part of the performance it self, an intercooler is still a fundamental part of a turbocharger system. Although there are two types of intercoolers on the market – air to air and air-water cooler, only air to air exchanger is practical on the street type cars and endurance . Charge air cooler water do wonders on very short distances and is ideal for towing cars. You can think of one as a radiator that cools the air compressor pumps that wheel in the intake manifold. This compressed air is called the intake charge.
Heat is a by product of the compressed air and when air is compressed, as when the turbochargers and other forced induction systems are used, the air (intake charge) is heated. This is called the thermodynamic effect of compressing the air. internal combustion engine, the air temperature is important because it affects the air density and because the excessive heat leads to pre-ignition, knocking and detonation. Role in the intercooler is to reduce the temperature of the intake charge. Intake charge cooling has two important advantages: it makes the intake charge more dense – more dense air produces more power, and prevents detonation. However, the intercooler is one disadvantage: it causes a loss of boost pressure! This is unavoidable, the best thing to do is to minimize the pressure loss caused by the intercooler.
There are several things you can do to design your cooling system to keep pressure loss to a minimum. You can embed a ring plate and the tank instead of a base extruder as the core and shell plate produces less resistance to flow. The internal flow area of the core also affects the pressure loss. The selection of a candidate with the correct internal flow area is important to keep pressure loss to a minimum. Here I found that the turbo system that produces a flow of 400 cubic feet per minute, requires an internal flow space of about 20 square inches can use the following table to calculate the area of internal flows according to the speed necessary turbo.
Having found an idea of what the internal flow field is desired, you can determine the actual size of the database you need. It’s a bit difficult. Usually, only about 45% of the intake charge will be in contact with heat exchange elements central heat exchanger. So first we have to divide the internal flow area required by 45% and then divide the result by the base layer. This gives us the following formula:
Internal flow area ÷ 0.45 core thickness
While we speak of the base layer, remember that the intake charge passes through the core length and cooling, the flow of air through the thickness of the soul, but every inch of the subsequent base layer is 40% less effective because the air flowing through the heat upward. Thus, a thinner core intercooler with a larger surface fontal is more effective than thick intercooler with a smaller frontal area.
It can also improve the efficiency of your intercooler by installing a pipe to it. Without a pipeline, about 25% of the molecules of air passing through the heart, the rest will follow the path of least resistance around the nucleus. Any improvements that increase greatly the efficiency of your broker.
If you are using to increase the pressure on 91-93 octane gas and a relatively high compression ratio, you may also want to complete your system, intercooler water spray.
