A intercooler is a unit that is designed to cool air that is
fed from the turbo or supercharger.
Air/air intercoolers are a popular type of intercooler, as they
are relatively simple and reliable. A well-designed Air/Air intercooler
system is a cost efficient and reliable method of reducing intake
charge temperatures in forced induction (turbocharger, supercharger)
applications. As it has no moving parts, the Air/Air system is
almost maintenance free, requiring minimal maintenance and attention.
Here at Trikab, we have constructed
and installed a wide variety of Air/Air intercoolers to suit customers
specific requirements. We can fabricate an intercooler to suit
your exact needs.
Intercooler cores are available in a range of thickness'es to
suit. 30mm, 43mm, 55mm, 76mm.
An air/air intercooler consists of a tube and fin radiator. The
pressurised air (post turbo) passes through thin rectangular
cross-section tubes that are stacked on top of the other. This
air is exposed to the large surface area of intercooler that
absorbs and transfers the heat through the thickness of metal.
Outside air - driven through the core by the forward motion of
the car - takes this heat away, transferring it from the intake
air to the atmosphere.
The speed of the vehicle is important to maintain the cooling
effect of the intercooler. If the vehicle speed is not maintained,
the ability the intercooler to cool the pressurised air is reduced.
If desired, one or more fans (we use SPAL) can be fitted to the
intercooler to ensure air flow through the intercooler is maintained.
Low speed applications require larger surface areas to be effective
while high speed applications can use lower surface areas.
