hey guys...i've been working on a project for quite some time. I bought a container box from curver (aka rubbermaid) with dimensions 58cm lenght x 38cm widht x 42cm height and i have installed 3 fittings for the lighting, i painted the container white and i used a black tape in order to stop the box from glowing. I'm using 3 42W compact fluro lamps rated at 2700 lumens ( 2 of them daylight, one cool white) and i have one hole as intake and 2 holes for exhaust. All three holes are constucted like so: i used PVC 90 degree curved pipes acting also as light trap. the problem is like this: how do i install the fan(s) - let's say, one at each exhaust hole) since these holes are 40 cm above the floor? any ideas guys?i cannot mount them on the box itself since i have the PVC pipe lines there any ideas?? or is it easier to just put a fan in front of the intake hole and thus push the hot air out??? will this be an efficient cooling method?? thanx guys
i think this flange will be out of the question in this shithole place i live. Will the installation in front of the intake hole do the job?
Hi Foundas, If u use the fan to suck air out it works better than using it to push air in. thats called active exhaust, passive intake. You should use 2 intake holes to every 1 exhaust hole to decrease the velocity of the incoming cold air.I dont understand why u cant mount the fan to the pipe? Use a piece of light rubber(not hard rubber),and put it between the fan and the pipe to stop vibrations running up the pipe,and use a good sealant to keep it stuck to the pipe and then stick the fan to it,(silicone or sumtin?) hope that helps, CWL
yeah man, celtic knows his shit, and i forgot about that 2 for 1 thing, i need to redo the intakes for the box i'm desinging.
the problem is that i already cut the holes for intake and exhaust. 1 intake, 2 exhaust... so, can't use celtic's idea. i think i'll put the fan in front of the intake hole, rated at about 100cfm and see what will happen. I hope i can take some pictures today and upload them Foundas... Better living through Chemistry
Cheers hippie! Foundas do whatever u think is best bud, Ure box is gonna be at a higher pressure inside so any leaks and flimsy sealing will become noticed very quickly indeed,although if its done properly then it should work ok i suppose,just a harder and more awkward way to do it i think, let us know wot happens bud! Cya in da fog! CWL
as for the fan's power...how many cfm will i need for this specific box? again, the dimensions are 58cm lenght x 38cm widht x 42cm height
about 3X the volume of the box per minuite, convert your measurments to feet then x3 and you will get the goal CFM.
