Radical new way to cool cylinders

[808ministroke]

I have been running this idea in my head for quite some tim. I think it all might stem from the backed at my front radiator on one of my mopeds Came off of one of my dad's super computers that hes buddy built Out of commission of course I would never just dissect a flawless machine One more thing about that computer the large radiator that was mounted towards the very top of the huge case it's had 4 fans that wereSilent as f*** 2 on the bottom pushing air through and 2 on the top pulling which took up exactly the area of the radiator itself so OK on to my radical idea.

Well mostProcessors aren't or weren't water cooledAs a matter of fact graphics cards which probably demand more power and therefore cooling then the CPU itself are very rarely even still liquidLiquid cold. However over the years they have devised some pretty interesting cooling mechanisms for those graphics cards as in multiple copper rails which I believe have some sort of oil in them Along with a vast amount of fins and a good amount of fans all put together in a way where the air was either pulled in from one side and pushed out the other, I think this is called a blower I think this is called a blower Or else getting circulated in the same direction before the films Or else getting circulated in the same direction They cool the GPU's chip by a contact point which The one I'm holding A&E VGA G force GTX770 Is a copper plate directly directly bolted on top of the copper pause witch Extend out to the cooling fins on both sides with a fan above either side, Thermal paste is used to add here the chip to this copper plate.
What If I ground down the side of a cylindor even ahead for that matter that was air cool Adding probably triple the heat dispersion that the normal fins would add plus if I powered the 2 fans I would assume that the cooling could be just as much as from the forced air cooling they already have So my theory is if this were done one might be able to get twice the cooling capabilities off of an air cooled cylinder for a pretty cheap seeing as a parts card would be a couple bucks all you would have to do is hook up the fans to a power wire which wouldn't be hard You can even usually control the fan speed if you wanted to does anybody think I'm on to something

One thing about computer chips is that they have nice flat surfaces that allow contact of cooling devices across their area easily. Your cylinder does not. It needs to be cooled all the way around.

Not sure how well it goes with copper directly attached to large chunks of steel or aluminum. The head seems like the easiest to try. If you get ambitious, make sure you collect plenty of CHT data before and after.

CPU parts are fragile in comparison to auto/moto parts if you are talking about adapting vs some full-on custom cooling build. Not meant to be rained on and dirty and I'd hope the PC doesn't experience the vibration and jolts that a scoot does. Even in the fan department, some have said they use PC fans on radiators. I look at that as maybe it passes as good enough. I put a small automotive fan on my scoot's radiator and it's way more robust and I've never seen a PC fan that would move the amount of air that it does. I believe I can count on it, where I'd feel like I was crossing my fingers relying on a PC fan over time.

In comparison, you can mount radiator(s), pump, hoses and a liquid cooled cylinder kit on the popular 2T scoot engines somewhat easily and liquid coolant can surround the combustion chamber, cylinder, ports and even flow into the cases with some setups. It's gonna be tough to get that level of cooling with copper plates and tubes. Most of the time in summer heat I may see 150F coolant temp and CHTs well cooler than any air cooled setup I've ever had. Innovation is great, but sometimes it's way easier to go with what already works.

That said, I'm all for it if you want to experiment with it. Keep us posted.

For reference, this is how CPU and GPU coolers work:



These are liquid-cooled, kinda-sorta, with capillary action replacing the need for a pumping mechanism. I think.

I used to be in IT back in 2000-2008 I pulled a lot of that stuff out of servers as I scrapped them. Made some good money from trailer loads of E-scrap. Anyways I had the same ideas you are having, but never moved on them. Heat sinks require intimate contact with what they are trying to cool, a machined flat spot would be needed on whatever you are trying to cool for it to work. The pipes you see on them are called heat pipes and are filled with a grey paste, at least the ones I cut open were. It would be really cool to design a cylinder and head with lots of flat area, and get a custom designed wrap around heat sink to go with it. Sadly as Brent mentioned, I think water cooling is king for now, but it would be cool!
