increasing radiator cooling

[frostmeister]

I was speaking engineering with a guy at work today who used to work on hydraulics equipment, and a possibly usefull suggestion he gave was using a funnel on the front of your radiator fan. It might not yeild that much of a benefit, but I wondered if anyone's tried it? The details are that sticking a kind of "reverse shroud" on the front of a fan, makes the air flow less turbulent, and aligns it to the axis of the fan before it hits the blades, giving better air compression, like a venturi carburettor apparently. I'm going to make one out of some card the next time I have some handy and see what difference it makes. I've been watching my ambient temps and cpu temps closely recently, and will make a few logs with MBM5 before and after to see if it makes much of a difference... :)

sounds interesting. Let us know how it works.

I doubt it would make any difference unless you are pulling some SERIOUS airflow through the thing, say like a 210cfm 162mm rotron.

I recall something like this from way back when cars used carburetors. Seemed it aligned the airflow better or something. It would probably garner a few more CFM, but I'm not sure if you will see any temp difference. Let us know!

Yeah, will do. Think I'll make one out tonight if I get the time...

hmmmm innnntresting

..."reverse shroud" on the front of a fan, makes the air flow less turbulent...
- also makes more resistance. (restrictive)

...and aligns it to the axis of the fan before it hits the blades, giving better air compression
- It's called a "Velosity Stack".
Except that you use it like a funnel
It is suppose to smooth out the air flow entering.

Either way, give it a try & let us know what's up.


:cool:

If you look at big rocket motors they have an expanding cone. It helps to increase the thrust output depending on multiple factors like the angle and thrust output. The same could be applied to fans I guess.
