Leading
charge air cooler manufacturers
We meet our customers, wherever they are, to truly understand their needs and requirements.
Our heat transfer solutions are individually designed to meet customer requirements and specifications.
Our experience and focus help our customers achieve a short time to market for new products.
Our durable heat transfer solutions are designed to reduce the total cost of ownership.
Monoblock:
We have designed the Monoblock cooler for us to be able to supply the best possible solution for a long life-time of the charge air cooler in operation on a reciprocating engine. See our brilliant range of Monoblock charge air coolers here!
Our Monoblock Charge air coolers
Scale:
Our cooler comes in a vast range of sizes. From the smaller ones suitable for off-highway engines to the very large ones used for the 2-stroke main engines for the container ships which weighs several tons.
Stress:
Our charge air coolers are designed to minimise local stress concentrations that would otherwise be fatal in regards to vibrations. The cooler being hot on the inlet side and cold on the outlet side will experience a non-uniform thermal elongation. This is evaluated through our use of advanced digital models as FEA (Finite element analysis) and CFD (Computational fluid dynamics). Combined with many years of experience we have developed the design details that matters.
Environment:
Our cooling surface is designed to be efficient and stay efficient through daily operation. This can be further improved by regular cleaning with our Tersus cleaning system. An efficient cooler which always provide the designed capacity will ensure engine efficiency and good fuel economy.
What Is
A Charge Air Cooler?
A charge air cooler is used to cool engine air after it has passed through a turbocharger, but before it enters the engine.
This is their main function. The idea is to return the air to a lower temperature,
for the optimum power from the combustion process within the engine.
More specifically, it is a heat exchange device used on turbocharged and supercharged (forced induction) internal combustion
engines to improve their volumetric efficiency by increasing intake air-charge density through isochoric cooling.
A decrease in air intake temperature provides a denser intake charge to the engine and allows more air and fuel to be
combusted per engine cycle, increasing the output of the engine.
The charge air cooler is designed to cool the charged air from something in the region of 180°C
to 220°C, down to around 40°C. It achieves this by using cooling water.
Charge air coolers range in size depending on the engine. The smallest are most often referred to as intercoolers
and are attached to automobile or truck engines. The largest are often used on huge marine diesel engines
or in power plants. They can weigh several tonnes in these circumstances.
Most are still associated with diesel engines, but Vestas aircoil manufactures specialist air coolers for gas engines too.
The first marine diesel engine charge air cooler was built by Vestas aircoil A/S in 1956. Look at our history here.
The phrase “charge air cooler” is an all-encompassing term, meaning that
it cools the turbo’s charged air before it is routed into the engine.
