gold folio for heat insulation |
it is said that gold folio is used in formula1 cars to protect driver
cockpit from the large amount of heat generated by the engine. in which
part of the car of they use gold folio, covering of the cockpit or
engine? gold is a good heat conductor so it should not be used to
protect cockpit from conductive heat. gold is the best radiant
reflector so it may be used to cover the engine bay or the side of
cockpit to protect from radiative heat. but i am not sure about the
amount of radiative heat an engine could produce. so what do you think
about it? how do they really use gold as an insulator?
thanks

Gold is a heat reflector, not an insulator. Between cockpit and engine.
AL foil works good too.

it is said that gold foli
"foil" ... not "folio"
is used in formula1 cars to protect driver cockpit from
the large amount of heat generated by the engine. in
which part of the car of they use gold folio, covering
of the cockpit or engine?
Either or both. It must not be in physical (conductive) contact
with any surface. More layers will provide more isolation.
gold is a good heat conductor so it should not be
used to protect cockpit from conductive heat.
Right. It provides a reflective surface, that does not oxidize,
and is chemically resistant to anything that might get sprayed on
it.
gold is the best radiant reflector so it may be used
to cover the engine bay or the side of cockpit to
protect from radiative heat. but i am not sure about
the amount of radiative heat an engine could produce.
Enough to start a cockpit fire during a race.
so what do you think about it? how do they really
use gold as an insulator?
A radiative barrier. Just like the metal plate attached to the
exhaust pipe on opposite sides of the catalytic converter,
"floating" between the converter and any body parts. The plate
reaches some termperature between the converter and the body...
and stays there.

Also used in the Rolex series.

I dunno, but IIRC Raikönen had diamonds in the steering wheel ;-)
