Hi Mr. Spears and Spearco
The Air-To-Water Intercooler message list I'm on received the below inquiry.
Could you please give us some insight? I'll pass the reply along

Subject: # of passes in radiator?
I know size is king, but is there a certain layout that makes for the best
cooling?
Before i dropped my project, i had a PermaCool 1004 radiator which was approx
.75" x 2.5" x 24" with a single inlet, turnaround and single outlet.
Is a unit with more passes better, or is it the total length that's more
important

Size is the greatest factor in cooling. However the fin design of the core
also would play a major role in the efficiency of the core.
Spearco
And my commentary:
Tried but not sure this nails it down, not sure you can in general terms. I
say you have to compare one design against another. A 12" x 24" cooler with
2 square feet frontal surface area with 4 passes 24 inches long of 96 inches
total length might not be as efficient as a 12" x 18" cooler with 1.5 square
feet frontal surface area and 6 passes 18 inches long of 108 inches total
length. The 12 extra inches represents 12.5 % more tube length in the cooler
that's got 33% less frontal area. I can see how fin design would tip the
scales, but this is just an example I pulled out of the air. It could well
be that cooler design is so standardized that the bigger cooler will almost
always have more tube length except where you have a small stacked cores
cooler competing with a larger single core cooler. If space is a problem you
might have to give up something to get something. What's good for the goose
might not be what's good for the gander if you can follow my drift. Each
application has it's own problems and like they say on those tests; you have
to find the most correct answer.
