A-pillars as ducts to route hot radiator air to the roof?

[g-force_addict]

If you could use the A-pillars (and/or the A-pillar tubes in a rollcage) to route hot radiator and engine area air to the roof
Where would you place the hot air exit?

How it would be different if you could use some electric blowers for it

Fore/aft: In the windshield header, roof midsection or backlight header
Side to side: roof edges or roof center.

There is nothing stopping you from running hot air through or next to the a pillars to the roof.

Nobody are doing it though.

I think that answers the question...

By this line of thinking no tecnological advancements are ever possible.
If its so good Why nobody thought of it before?

What benefits would there be in sending hot air out through the roof? What problem are you trying to solve? Doing something different purely for the sake of doing something different is not an advancement and its not innovation. You need to have some sort of problem to solve before throwing "out of the box" solutions around.

From my point of view, putting a hot air exit on the roof will reduce the downforce produced by the rear wing because it will be running in less dense air. Is that what you wanted?

I think what the OP is trying to suggest is that you might be able to do away with a conventional front mounted radiator in a front engined sedan by using the large surface area of the roof instead.

Some benefits I could see:
- No front mounted radiator would mean a much more aerodynamic front end with the only intakes required being for engine inake and brake cooling.

Some negative things I can see:
- Questionable cooling capacity
- In hot sun it would be almost totally ineffective
- It will raise the center of gravity
- It will require a strong pump to get the water up that much higher than the engine
- Messy if it leaked

EDIT: I see the OP actually meant hot air and not water.
