heatsink where to buy?

Stefanoo · 22nd April 2010, 10:25 PM

Hi everybody,

I need to buy big heatsink just to test and develop a power amp, so they don't have to be of a specific dimension nor color nor finishing for now.
I need to get like 4-5 square/rectangular shape something like 12'' X 12'' just to give a rough idea of dimension.

Do you guys know where I canl get somethingike this in the US?

Thanks a lot.

If its just for testing I get them from the local scrap yard. Industrial motor inverters and such have some fairly large heatsinks plus loads of other nice bits.

Profil-, Strang-Kühlkörper-Sortiment im Conrad Online Shop

Looks pretty good

the store you pointed out is in Germany (I am looking for something in the US) and price is fairly high as I just need something less nice only for test purposes.

Old sony 38 inch CRT TVs have huge heat sinks as well as acrap computers. A heat sink with a fan 2"x3" will dissipate as many watts as a 12" square heat sink without a fan. Old Projection TVs with 3 CRTs also have huge heat sinks including one attached to each CRT.

And dead consumer stereo amps/receivers will have heat sinks in them.
