Another
newbie question.
After
reading Paul Lamar's cooling text:
http://home.earthlink.net/~rotaryeng/how-to-cool12.txt
I was left
wondering
if water coolant could be replaced by a liquid with a higher
boiling
point (such as oil). That combined with running the coolant at
a
constant higher temp might lead to an increase in cooling efficiency
since
the difference between the external air and the coolant could be
increased.
Is there a danger letting the temps of the rotor housings
operate
at a higher temp as long as we are below the melting point by a
safe
margin(say 350 vs the water cooled 200-250)?
Ignorance
is bliss! :-)
Mike;
The big issues are
that the specific heat (heat carrying capacity) of oil is about half that of
water; so you would need very high flow rate, which is a double problem since
the viscosity is much higher, the pumping power required is very large.
