Hot head, cold feet

Post by Bendyknees »

Am in the process of making an air circulator for the van(bit o pipe from the roof wit a pc fan in 1 end :) ) as in my hightop all my lovely heat hides up in the roof and escapes out the roof vent :(
My question is though is it going to be more efficient to have the fan mounted at the top blowing downwards or at the bottom sucking upwards.
Who has a degree an can put it to some use :lol:

wouldnt it be better just to isolate the vent from the nasty outside environment and block it? i went to austria in february in the back of a minibus(cold) we taped the vent up (warm). but if your van is that cold, i take it your unfortunate enough to have an Aircooled!!! in that case, sorry thats as warm as it gets.
ps, a fan isnt going to do a thing.

If you insulate the roof well, the heat will come down and say hello, rather than disappearing, as well as shutting the roof-vent when you're cold?

Who has a degree an can put it to some use :lol:

You don't say what discipline is required though - Fluid mechanics perhaps :wink:

You need to pipe the hot air down to your lower regions not blow it down, a centrifugal blower would be best of at least 3" diameter, hose ditto dia. not a silly axial-flow fan

How about a 12V oscilating fan? and drape a curtain to isolate the cab, we did this in the bay and it made a huge difference.
