Re: Surface radiators
How about making an aluminum belly pan/surface radiator?
Because it's hidden under the car aesthetics wouldn't be that critical. Several possibilities come to mind:
- An aluminum skin with aluminum tubing bonded (mechanically and thermally) to the upper surface with coolant running through the tubing.
- Aluminum flat panel heat exchanger material, if it could be found.
- Exposed rectangular aluminum tubing (maybe 1/2" x 2") which serves both as a frame to support an ordinary coroplast belly pan and a surface radiator.
Certainly the entire belly pan wouldn't need to be a radiator so you could position the radiator portion where it wouldn't have to be bent or notched and where there would be less chance of damage from stones, etc. kicking up from the tires. Maybe a strip down the middle of the car, or crossways in front of the front wheels?
