my heat sink picture

space2000 · 3rd July 2008, 08:20 AM

hi all,

i am now on the construction of the heat sink. it is as i told you.
it is now i am making. hulf of the way i took picture let you know how i am making. center will be quiet type mid speed fan. i have nothing so special tools available. only dril and scru driver....pencil and calculator. today probably will be finsh.

all metals are aluminium.

metal of the plate = solid aluminium
diameter of the plate = 12inch
plate thickness = 10mm
fins thickness = 0.3mm
fins height = 4 inch
fins length = 3.5inch

what do you think about heat disipraion? how many watts can put on it?

thanks for your view and comments.

spcly dear Dx.....need your comments too...as i am looking for turbo-DXxxxxx ....on it.....ha..ha...

Thank you
michael

Wow!! That will look impressive when done!

Are you going to anodise it? I posted a rather simple procedure under "Everything Else" on how to anodise at home.

Cheers

It's not looking bad, the efficiency of those fins may be less than you might like if they're not extremely well coupled to the base. It might be worth trying to find some transparent PTC and putting a thin layer between them and the base. If the metal the fins is made out of is thin, you can also improve how well it clamps down to the base by adding a thicker strip of something like steel between the screw heads and the top of the folded bit on the fin - so it spreads the squeezing out more.

Will you use some thermal compound between the base and fins? In any case expect significant losses. And a lot of vibration pickup.

ask the moderators to join them.

Very nice Flying Sauce heatsink.... a nice UFO (unindentified flying object)....hehehe.... i like that.

The power, in my experience, will be 446 watts.... or ... a 446 watts rms amplifier (or amplifiers), producing around 650 watts of heat, will be "controled" by your flying sauce heatsink.

How to calculate.... i have learned that observing what is good for a 10 watts power amplifier, a RMS clean power, sinusoidal power, undistorted, continuous ..... i have found an aluminium square of 10 centimeters side and 2 to 3 milimeters thick would work fine..... so..... based on that....... it is just a very easy calculation.

If 100 square centimeters can hold 10 watts amplifier... then..... XXXX square centimeters will hold (W)

Carlos

Clean the thermal paste excess using cotton swab, clotch with petrol diluting material, alike gasoline, thinner, Kerozene, or paint remover.
Congratulations, you are having an excelent idea...you may create an excelent amplifier, one of the most pretty of this forum.

The Flying sauce power amplifier.... wonderfull idea....my deep and sincere congratulations.

regards,

Carlos

You will make excelent advertising to the Corporation.

Will invite you to work with us..... ahahahahaha!

Corporation does not exist..... not today.

Using out space technology, now will have a flying sauce amplifier.

heheheh.... Great!

regards,

Carlos
