Cooling options for 2014

[dragosmp]

If we look at the shape of the intake in the sidepods today, it seems to me they're quite a bit smaller than a few years ago. Now the intake is a triangle with rounded corners (roughly speaking) whereas in the mid-2000s they were much more square-like. It seems that at the same car speed (& pressure, temp, etc) the airflow was much higher only a few years back.
My guess is that there is quite a bit of room to grow the size of the sidepot entry to cool a few more watts, even though I share Blackout's thought that the new engines should be quite a bit more efficient, thus not needing more cooling. Maybe the re-routing of the exhaust gasses thru the engine compartment to the turbo really heats up the other parts as to make cooling more of a problem?

That is a non issue. The issue with 2014 cooling capacity is the additional cooling between the turbo compressor and the engine. This is called inter cooling and it is required to generate optimum power of the engine. Adrian Newey referred to this requirement and stipulated that the side pots will grow to satisfy it. But the intercooler may not go into the side pots at all. Contrary to the 80ties design we only have one single turbo. So if only one intercooler is needed the single heat exchanger may go into the place where today you have the air box or normal cooling will go into the left side pot and intercooling into the right. That may reduce the plumbing quite a bit.

The turbo engine may result in more heat transfer into the engine oil. The turbo spool will be oil cooled, and the piston crowns will also likely require oil squirters.

You need to cool the Energy storage /Batteries ,as these carry a lot more energy then and it has to be charged and deployed so quite a bit of extra cooling capacity is needed there.
As the temperature level is considerably lower then engine coolant you run into efficiency trouble when it comes to get rid of the heat ..as the delta t is low .

For sure, the battery, power electronics, and motor/generator of the KERS will require a coolant flow with an inlet temp below that of the engine. The permanent magnet materials of the motor/generator need to be kept below temps of around 180degF.

Yeah, the MGUH and MGUK together with their associated inverters and energy storages will require liquid cooling capacity. So you are looking at least at three different cooling systems.

The thermal efficiency improvements of the 2014 power train over the V8s are mainly going to be seen in the exhaust energy flow. That enthalpy stream will be significantly reduced while the various cooling needs will increase as we have already learned.

The additional volume that is relevant for packaging will be mainly caused by the higher plumbing requirements of the fluid systems. The radiators by themselves will also increase in terms of cross section but you can stack radiators with the leading circuit having the lower temp to reduce cross section in the side pots.

And it wont be easy to place the gearbox's radiator above the G-box; the Turbo and the exhaust pipe wil encumber that area a bit. So the sidepod might have to accommodate that rad too.
