Relocating that darn rectifier
Written by attitudehats on 2/10/2012 at 06:36 am

Every once in a while I find myself starting to think about adding longer
cooling fins to the R/R stumpy fins. I even envision making up something out of
Silver, the best conductor of heat(and electricity) out of all the metals we
know. I know for the best wicking results, the metal fins must be thin, because
the heat will wick away fastest that way. I can even almost see a way to do an
impression of the stumpy cooling fins, to mate the junction tightly, ensuring
best heat transfer away. I even wish sometimes I had a machine shop buddy around
me, so I could bounce off my bizarre ideas and questions. A very thin Copper
plate would do nicely. Not as great as Silver, but a lower cost material choice.
Every time I see some computer's processor cooling fins get thrown out, I see
flipping it upside down, and cutting out the fins necessary to try and dovetail
fit it, and use a relatively small drill to punch alignment holes and rivet it
together. I'm pretty sure having faster heat transfer fins jutting out a couple
more inches would be helpful in wicking away the intense heat.

Having a better R/R that runs cooler from another bike is likely the most direct
solution to this problem.

tubing to funnel air, and the results were less than stellar. Yes, the frame of
the bike is used to channel the heat away, but it's a bad source for a heat
sink. That's why heat sinks on computers are made of aluminum or copper and not
steel. I also read that a PC fan was tried with a digital thermometer attached
and the difference was not that much. Basically, the location was the biggest
issue. No air flow.

a little space in front of the trunk. Opposite side of the battery?
