Cobra is manufactured
from copper and brass. Copper has been, and will be for
the foreseeable future, the ultimate material for heat
transfer, long lasting durability, and is repairable if
needed.
NOT JUST A LOUVERED FIN. Cobra's
fin is designed for maximum cooling efficiency. There
are louvers at each fin crossing. These louvers are computer
designed and manufactured to a precise angle and length.
Their location and angle on each fin is designed to eliminate
air boundary build-up (a layer of air that insulates fin
material from air flow). There are 620,400
of these precise louvers in an average Cobra
street rod radiator which accounts for 206,800
air directional changes taking place throughout Cobra's
core area. These air directional changes break up air
flow, creating a scrubbing effect on the fin material,
thus eliminating air boundary build-up. These changes
may vary, depending upon the application. At Cobra's
fin edge the copper material is hemmed to double thickness
for added strength and durability.
The distance between each tube (Fin
Height) is precisely 1/4". This 1/4" fin height
measurement is unique in that it allows for the additional
number of fins and tubes through Cobra's
core area and is manufactured exclusively by Walker.
Also, Cobra's fin height is computer
controlled to give a uniform bond between the tube and
fin area. This uniform bond is essential for maximum heat
transfer and strength to withstand vibrations.
Cobra's fin count is
17 (Z-Series 12), which means there are 17 heat transfer
fins in every vertical inch of Cobra's
core surface. This fin count is unmatched in number.
You will also notice that Cobra
is considerably thinner than other street rod radiators
on the market. Cobra's unique design
requires less cubic inches for maximum cooling efficiency.
this allows for additional fan clearance in the engine
compartment.
Cobra's superior design
and unsurpassed quality provides a cooling system required
for today's high performance engines.
