This interesting query was emailed to me the other week…
Plastic vs Brass Baffles? Do spiral
baffles add any cooling efficiency?
The plastic baffles are new, and the jury is out… I can see the obvious benefit of not stressing the mold base as they are installed, as well as the textured surface to increase turbulence within the water channel. Spiral channels, as a rule, tend to provide consistency of cooling around the core. These designs also help to reduce the potential of baffle deflection.
Personally, I would love to see some independent studies comparing the spiral design baffle in brass vs. a turbulent promoting design in plastic.
