The trick here is keeping the only part of the fan inside the shroud, when all of it is contained, you get harmonic turbulence that reduces flow below that of an open fan, so the rear part of the blade twist is left outside the shroud to provide a little outward bleed of air which stops the harmonics. Instead that air is forced to escape in the direction or the rest of the air flow which is at 90 degrees to the fan's plain of rotation. It catches the air flow moving along the length of the blade and stops it from being slung off the tip. Both feature the PERRIN name for that custom hot/cool look. Available in black, red, neon yellow, or hyper teal powder coated aluminum. A proper fan shroud enables the air to be properly distributed to the entire cooling surface to provide maximum cooling. This does two really useful things:ġ) It encloses the entire area of the core so that when vacuum is formed by the spinning fan, air flows thru the entire surface area of the core greatly increasing the radiator's effectiveness as there are no dead zones where there isn't core working to transfer heat.Ģ) The fan running partially shrouded is more efficient than an open ended fan, the shroud acts like modern winglets on jet transports like the Airbus 320 and Boeing 737. The PERRIN Radiator Shroud caps the top of the radiator for a sleek new look. Radiator Shrouds A proper cooling system is essential to maximizing your vehicles performance and increasing the longevity of your ride. Obviously the fan blades only pull air through the coils its directly in contact. is that air flow is inhibited past the OTHER coils not touched by the electric. of the radiator actually HELP or INHIBIT cooling to the engine. The shroud is used to enclose the entire core perimeter at the radiator end and covers the diameter of the fan and about 1/2 the blade's twist depth. So does an electric fan shroud that also mounts flush, block other areas. This leaves a lot of core area doing not much of anything regarding heat transfer to the atmosphere.

In this condition without a shroud the only air passing thru the radiator core is that area directly in front of the fan. 2000 FORD E450 (Stock 24604) Radiators & Radiator Parts / Radiator Fan Shrouds.
