Radiator Thermal Test Bench Progress

[Martinm210]

I think you are making the radiator test way too hard by making it a fan test also. You just need a box you hook to the radiator with enough of a blower that can be create a pressure drop from .01" to maybe .5" across the radiator. I don't know what we have in practice now, however based on the fans I imagine it is in the .05-.1" range.

That would be quick, and neat. Then you can just select the fan with a shroud in pull that will duplicate the pressure drop you want.

BTW, what was your room ambient? Did it differ from air in?

Yes, but that wouldn't capture real world fan hub effects for folks that don't use a shroud, which I would esimtate is the larger majority of users.

I'm more interested in capturing something that is useful and easier to understand for people.

A CFM base flow chamber would have to be a large facility too, I just don't have the space where this little bench I'm using is very simple and small.

It'll work out..


I don't understand what the ambient vs air in question really is. air temperature is extremely sensetive and if I measure room ambient 10' away it really has very little correlation, measure it on the floor and it's probably cooler than air in, measure 6' up it's higher. Air temps are really really sensetive and different everywhere, that's why I've included 8 individual air in sensors to average out the mess of differences.
