And if good examples can't be found, what would've been good practices for, say, converting the Spitfire design to using it, or improving other fighters with ventral radiators?
The P-51's ventral radiator was designed to separate from the boundary layer. The KI-61 and MC.202 did not have that feature.
A lot of fighters was manufactured with ventral radiator, semi-burried, that used Merredith's principle
Different companies have different views on how some things need to be adressed. Even within the same company, there were attempts on improving the cooling system(s). MTT changed the cooling system on Bf 109 from E to F, and then again from F to G (if we discard the pre-Emil 109s, and forget the oil coolers for a moment). Spitfire was also a subject of changes. P-51 went through 4 different cooling systems.If you look at the proposed KI-62, you'll see that the engineers were trying to address the cooling duct issue with a more streamlined design.
How it would have performed, is anyone's guess, but it does appear to present less drag than the cooling system on the KI-60/KI-61.
Well, they went for the boundary layer splitter on the F over E, duct the boundary layer up and over the radiator core. Which is more elegant/efficient.and then again from F to G

Then with the G they had choice, they needed a bigger core to cool the engine. Keep the boundary layer duct and increase the frontal area of the radiator (make it deeper/lower or wider) or get of the duct and raise the radiator higher into the wing. A bit less efficient using the boundary layer but a trade off vs the larger size duct/frontal area?
Could be.All of that, plus perhaps the boundary layer duct was not as efficient as the designers thought it will be?
The KI-60 had a large and long radiator housing, the KI-61's radiator housing was shortened, but still bulky.Ki-60 and Ki-61 have had different cooling systems between the two.
The KI-62's radiator was to have been moved forward of the cockpit, in a streamlined housing with an adjustable exit flap.
