electric cooling fan

18 Oct 2008 23:24 - 18 Oct 2008 23:37

im on a roll here tonight guys!:laugh: ive been tossing the idea of mounting a small 12v fan between backbone tubes in the area where coils normally sit to pull air over the top side of motor while idling,does anybody know of some kind of a small motor that would fit and still be able to handle the heat generated?everybody gave me hell about progress so here i go again!:laugh:

Still recovering,some days are better than others.

they used to make computer fans up to 90mm that would move 120cfm and spun at roughly the speed of light. i thought about putting one on my oil cooler.:woohoo:

edit: called "tornadoes" and they are 12v
edit #2: around 80 decibels too

edit#4: mmmmmmmm edits yum

Buy the small chrome fan guards that go in front of them. Worth the extra few bucks.:laugh:

BTW: those fans usually run on DC motors which have a solid state controller inside that regulates speed and limits current in case the fan is blocked (stalled). I don't think those controllers will like getting too hot?

no telling. i have a habit of making things just to see them ignite in a giant fireball or not. I think he'll be fine and if not he ruined a 11 dollar fan. Some of these fans can take a bit of heat.

By coincidence, I used to design cooling systems for electronic equipment.

I can't help but wonder if that small fan would actually do anything? In electronic systems, those fans are designed to deal with power dissipation of maybe ten or twenty Watts. A bike engine is probably dissipating thousands of Watts or more.

hmmm you don't have a whole lot of spare power to be throwing into a cooling system other then using a fan off a water cooled bike. Would getting a small fan and using it on an external oil cooler be a better idea?

maybe a temp controlled methanol injeciton? cools the engine internally and prevents preignition.
