Hi, fellow rotary enthusiasts.....I
am confused regarding radiator versus evaporator cores. Ed Klepeis can
make a radiator for me that measures overall 16 x 10 x 4 1/2, by
sandwiching two 2 1/4" thick cores together. Unfortunately, there are
two 2" wide tanks on each end, which reduces the cooling fin area to
12" x 10" x 4 1/2". I calculate that to a total area of around 540.
I have found an evap. core that
measures 9 x 13 1/2 x 4 5/8" thick. I believe that comes out to a total
area of around 561. That would fit perfectly in the cowling with even
less modifications to inlets, etc. (Read that as less work for me). I
have heard on this forum that evap. cores are a good choice for
cooling, as they can take high pressures. Is there anything else
I should consider regarding radiator versus evap core for cooling?
Inlet and outlet tubes look to be around 5/8". The core looks just like
one from a GM Safari or Astro Van except for the size difference. I
don't know if the 5/8" inlet/outlet tubes would be too restrictive to
flow compared to a radiator that would be made with 1" NPT
inlet/outlets? My guess is that once the water gets inside either the
evap core or the radiator, flow is going to be restricted by the tubing
sizes inside the cooling device regardless of the inlet/outlet sizes? I know that Ed Anderson, Tracy and others have
had success with evap cores. Any possible pros and cons would be much
appreciated. Thank you for your time and opinions. Paul Conner
