Heat Exchangers

[email protected]
It may have escaped the notice of the casual observer but the emphasis of modern vehicle design/development is not so much about style or performance (these are very much a given today) but in the management of engine heat. Thus turbochargers, once the dream of boy racers the world over, are now a common sight and will convert the otherwise wasted exhaust heat energy into useful work by pressurising the intake charge. Adding a further turbine downstream of the first - turbo-compounding we...

The intercooler

[email protected]
Practitioners of engineering design will be familiar with the concept of compromise and the trade-off of one engineering parameter against another. A good best example of this - the 'art' of design as it were - must be the task of cooling the intake charge on a turbocharged engine. Generally referred to as an intercooler, or if you are a turbocharger designer an aftercooler, the idea is to reduce the charge air temperature to as close to the compressor intake temperature as possible...

The silicone hose

[email protected]
When I think back to when I was first introduced to competitive motorsport - rather more years ago now than I care to remember - I wince now at some the things we used to do. At the time, it was very much a 'make do and mend' attitude, and the amateur weekend designer/racer would often spend more of his time seeking that certain part of the right size or shape to support his backyard vehicle build. A common part might be, say, a top or bottom radiator hose. If money was not a...

The cooling fan

[email protected]
Although a car properly designed for speed should never have any problems with cooling, there are times when the lack of forward motion can limit the amount of heat dissipated through its radiator. In earlier times, simple two- or four-blade fans would be powered directly via a v-shaped belt from the engine crankshaft, but these days when the cooling limit from the forward motion of the vehicle has been reached, the electric fan normally takes over. Used in competition - for instance in...

Coolant system efficiency

[email protected]
As the specific power of engines continues to increase over time, so does the demand on their cooling systems. And if an engine is delivering, say, 200 kW at any one time then roughly an equivalent amount of heat will also be rejected into the cooling system. Using my electric fire analogy that's 100 two-bar electric fires distributing all this through the vehicle radiator and into the local environment, and when put like that, it is a wonder we don't see more issues with the cooling...
