Heatsink for SOZ 10W

[akira]

Hi all,

I m building a 10W SOZ (or tring to at least) and m looking for heatsink. I ve found two different kind of :

Here is a URL with drawing of the two types :
heatsink list

The first is the CO 5409 (or CO 5063 they are pretty much the same profile). The other is the big CO 5260 (SK 141 type but bigger). I wonder which one I should use. I fear that the wings of the big one are not thin enough to evacuate the heat properly. Any advice appreciated.

Thanks

Akira

PS : Does anybody has a link to a direct on-line catalog of heatsink profiles ?

bottom line with SOZ, buy the biggest heatsink you can
find / afford.

I think they do 150 watts of heat each....or darn close 🙂

I got 2 boxes of these heatsinks. They are BIG!
You could build a 10 watt SOZ with them no problem! 🙂

you could cut 2 of them in half for 4 sinks and make a
square chasis. Put resistors on 1 sink and FETS on the other x2.
You have plenty of room in the inside for your power supply, etc.

i'm using them for my Aleph 2.
