Why I dont see anyone use heatsink system...

[zetathix]

Now I think that maybe I can apply this technology on my aluminium-sheet with other fin-shaped sheet that I made one. Think that you can use less fan for such as mini-refrigerator-power-like.. Anyone want to give me an opinion? :rasta:

not sure how your talking about using the heatsinks. but heatsinks are already used on things that get...well very hot. For instant, most ballasts are ribbed and finned and inside they of course have heat sinks. Water coolers for hydro use heatsinks to dissipate heat as well. The only place you dont really see them is hoods, because it would be too heavy.

where are you talking about using it?

Sorry, please dont angry me for my useless info.
I think that maybe I will appliy it to box-wall. Not only inner air circulated in normally, but 2nd finned-outer-layer will absorbing heats from inner air-temp. Like this

^ hot air
Out | F | In
| ^ |
| ^ |
| ^ |

cool air F> |

Because I'm used aluminium-sheet as I said before. Here where I'm stay have a little problem that min-temp = 27 C , Max-temp = 31.5 C (light off) and when light on is around 35-37 C. This temp level that I've tested it yesterday.
I think eveything will be cool down when i'm make a real growing. Oh, this temp level is measured when temp-probe's 4" far from 250w(hps) bulb and stiil didnt switch vent-sys on and didnt install a hood and 2 side wall yet. So I need to try something else that isnt a/c, If this plant = F, maybe I will use water to cool down a thing.

p.s. sorry for my poor english...and if you stoned too....peace.
