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
