Case Design

[nathan]

I'm just designing a case which i'll be making out of plexiglass. Looking at the cooling side of things. Can anyone think of a inexpensive way of testing the cooling flows. I Read somewhere to use smoke of some sort. But i'm not about to smoke weed just to test

Just any help or advice would do nicely. thanks!

Light a piece of paper on fire or something and test in the garage.

you could always rent a fog machine for the day, like the ones they use on stage. The fog fluid doesn't cost much and it won't stink your place out

U can get `smoke in a can`, I`ve seen fire-alarm installers test alarms in warehouses with them.

Have absolutely no idea how available it is, or indeed how much it costs.

How about a big arse army issue flare !!!! lmao

Ive thrown the same type of smoke nades the army/SAS use. I think he might actualy want to be able to see the smoke going into the case, with one of them in a grage you wouldn't be able to see your hand infront of your face

lmfao, that reminds me of messing about in my dad`s garage as a nipper and finding an old fire extinguisher. For some dumb arse reason I figured the handle won`t squeeze coz it`s stuck... prehaps hitting the handle with a hammer will budge it..

The handle was hence stuck in the open position and I dropped it and got out, slamming the door closed.

The whole garage was white powder coated.

Looked ever so tidy tho

I was watching this thing on TV about house inspectors and they were looking for drafts and they actually had this little tube and when you squeezed it this very light smoke came out and blew one way or the other if there was a draft.

If only i knew the name of it cause it'd work perfectly for what you need it for

you sure it wasnt a fine flour or anything, i remembeer those fake cigs kids have, that when you blow it blows out flour and looks like smoke.

 

[Ares210]

Lol ahhh i remember them

But nope it wasn't like a floury smoke. It was a very floaty smoke that was whitish in color lol

 

[nathan]

wasnt from a place like columbia was it?

only prob is it dosent last long

When I designed my comps I built a air flow gauge. I got a 2' piece of clear plastic tubing that a golf ball fit loosely into and attached a hose to the bottom. As you blow in the hose the golf ball raises.

That worked well to check different fans and grills/mesh.

My best gauge was my face though, if you blow against ur face its a lot easier to feel the air.
