Liquid cooled Regulator Rectifiers
For Rc-51, will fit SuperHawk by reversing hoses.
Keeps Diodes 5 times cooler by diverting coolant from radiator thru R/R.
Worlds 1st for bikes, the concept we originally designed for a small helicopter engine.
$200.00 plus shipping - worldwide.

That seems like a pretty crazy setup. If I were worried about the cooling I would probably just use peltier cooler between the R/R and heatsink. Plus you can find them for around 10 bucks for the size we would need.

Interesting idea.Might be worth the investment for a race application,but on the street I think it would be overkill.You can upgrade to a good aftermarket R/R for just under $100,but good luck with the unit!

OK this is a joke right? Liquid cooled electronics? Racing applications? I have heard of liquid cooling on speakers but only a thin jacket of coolant to transfer heat to the atmosphere. Ha ha very funny

No joke, and its less trouble than peltier wafers and heat sinks.
No liquid gets into the electrics.
Plus, peltier modules have limited service life, the wafer would fail sooner than the other parts would, making the whole thing overheat.
Also peltier modules stop cooling when their heat sink side saturates with heat.(= huge heat sink)
No way heat saturation happens on this unit !
This is not going to be a common item outside of someones racebike, of course.
Its expensive but works great. Sold 3 this year in Dallas so far. Not expecting this one to be a big seller anyway.
Im just trying to round out my line of R/R and similar electrical products with some rarity. ( no one else has done it )
The idea comes from back in the 1980s when Showa made a watercooled shock for the RC-250 racebike, and fed radiator water thru the shock body to cool it and keep it from fading during 30 minute motos. Lots of heat removed this way. I just borrowed the concept, since nothing on your entire bike gets hotter than your regulator rectifier except maybe the exhaust header. I would need to actually measure that to say, its probably pretty close.
Im putting this one on my own hawk this week for measurements.

My computer at work is liquid cooled. Back in the day I remember a few car amps (bazooka and I think MTX..maybe others) being liquid cooled as well. Technology has been around for a while

You know a peltier doesn't cool anything? It just moves heat, and adds a couple of watts at the hot end for it's own powerconsumption... So using one in this application is counterproductive...

Well if you put a big heatsink on the hot side of the peltier, and the cold side on the R/R it will keep the R/R cooler than if it weren't there.

Thats one big heat sink for a R/R . ( imagine a 200 watt amp under your seat for a R/R )
Ive worked with some peltier modules for years, made some Koosie drink coolers that will freeze a can of beer in less than an hour.
(imagine a koosie with a huge heat sink and fan on the bottom)
To remove 10 calories of heat thru a peltier(average calc)you create 1.
its a linear line out from there.
Peltier cooling wafers they are pretty cool devices, but they create a lot of heat and dont last very long.

Hey you do give me an idea though.
A peltier wafer INSIDE the liquid cooled R/R, cold side fixed to the diodes and SCRs, and the Hot side fixed against the copper water vessel.
That module would never saturate on the hot side.
Now thats a Peltier that would get freeking Ice cold !
I dont know if we need a refrigerated R/R, it might fail from being too cold ... lol
