Dig into the polini snake radiator today since I don’t want to do major work without my students.
Found something interesting besides a dirty radiator.
I seems between the backplate and the main body of the radiator there is a hard plastic plate. This plate seemed to have some residue from something leftover in the pattern of the snake.
I’m wondering if that was some kind of heat transfer tape?
It looks like the design is to have deep water channels that have the heat rise up the top, and get cooled by air blowing through the spaces between the cracks in in the little cross sections.
I would definitely say a pump would not help this design cool any better because the radiator even with air blowing by still wouldn’t be cooling the water fast enough to warrant a higher waterflow(my opinion, would love to hear yours on this).
I’m wondering what the deal with this plastic is....doesn’t seem to have any special properties to transfer heat. Makes me wonder if it’s just a sealing gasket and causes the radiator to perform worse?
I’m wondering what would happen if I used thermal tape like this: Thermal Interface Products Heat Sink Thermal Tape - 3M 8810 - 80mm x 80mm (1 piece)
On both sides of the “plastic” piece.
Or perhaps replacing the plastic with just that thermal tape?
Hoping to get a small discussion on this, toss around some thoughts.
I do have a more conventional aluminum radiator I could use but if I’m cooling both the head and clutch, I’m going to do separate loops so I’ll still need two radiators.
