How to improve your intercoolers efficiency

From:Xiamen Hosingtech Auto Parts Co., Ltd     Release time:2018-06-24

Overview:An intercooler is just another name for a heat exchanger that is used to cool air that has been compressed by either a Super-Charger or a Turbocharger. The intercooler is placed somewhere in the path of air that flows from the turbo/supercharger to the motor. An intercooler is needed because of the physics of air described in the Ideal Gas Law, that is PV=nRT.

How to improve your intercoolers efficiency

An intercooler is just another name for a heat exchanger that is used to cool air that has been compressed by either a Super-Charger or a Turbocharger. The intercooler is placed somewhere in the path of air that flows from the turbo/supercharger to the motor. An intercooler is needed because of the physics of air described in the Ideal Gas Law, that is PV=nRT.

Explaining the ideal gas law as basic as we can, we can say that because pressure and temperature are directly proportional, as you create more pressure with your turbo or supercharger, you produce more heat as well. At first one might think: “who cares how hot the air is that is going in my motor” , but there are two main reasons why this is a bad thing.

1. Hot air is less dense and therefore contains less molecules of oxygen per unit volume. This means less air for the motor in a given stroke and therefore less power produced.

2. Hot air also causes a higher cylinder temperature and therefore can aid in pre-detonationof the combustion cycle causing what we call, detonation.

When intake air pressures are kept at a modest or low boost pressure, an intercooler may not be necessary for your set-up. That being said, a colder denser charge will not only be safer for your motor, but add power as well. With their not being to many things that ad safety and engine longevity as well as power, adding an intercooler to your forced induction set-up is a no brainer.
