HOW MERCEDES KEEPS IT COOL
Current 1.6-litre V6 turbocharged units and their components – internal combustion engine (ICE), gearbox, both motor-generator units (MGU-K and –H), control electronics – are very sophisticated pieces of engineering that have high cooling demands.
The many radiators fitted on the car must be fed with cooling air via complex ducts, and teams use computational fluid dynamics (CFD) in order to come up with their designs and volumes.
On the 2016 title-winning W07, the roll-hoop inlet splits into three ducts underneath the engine cover: the central tube sends cooling air to the compressor (see red-coloured part), while the other two join to feed an ERS cooler sitting horizontally (see blue-coloured element).
