Why no radiators in boats?
(Gould 0738) wrote in message ...
I have a radiator. Its called a heat exchanger.

Technically, a heat exchanger is not a radiator.
A radiator transfers the heat of coolant to the atmosphere. IOW, it "radiates"
heat.
A heat exchanger, as the term is commonly applied, transfers heat between
liquids.
Technically, a "radiator" is not a radiator. A real radiator is what
you see on the floor of an old apartment building with no forced air
flow through it.
A "radiator" in a car transfers the heat of coolant to the atmosphere
by convection and conduction primarily. Radiation hardly plays a
part.
A heat exchanger, as the term is commonly applied, transfers heat
between fluids, not liquids and uses convection and conduction
primarily. Air and water are both fluids. Therefore the "radiator"
in your car and the heat exchanger in your boat are both heat
exchangers.
If this is not immediately obvious, put a peice of cardboard accross
your grille and disable your radiator fan and see how well your
"radiator" works when it must rely only on radiation.
