Curved/plyable or idea needed for heatsink

post #1 of 6
Thread Starter 
Hi,
I need some curved base heatsinks, or a heatsink thats plyable so i can shape its base, or if anybody has any ideads what the hell i can use please feel free to share.

Pic is attached, as you can see there is a big heatsink on one side of the motor and nothing anywhere else, i'd like to cool the rest , i'm using fans but i'd allso like some type of extra cooling from a heatsink or heatsinks.

Thanks

Take a blowtorch and soften up any solid aluminum heatsink. they are dirt cheap at lowes or home depot ect. If you take a piece of iron pipe the same diameter and curve you can use that to form it easily.

A blowtorch creates a temperature of about a couple orders of magnitude higher than the melting point of aluminum alloy. Since the goal is to soften the metal for workability rather then outright melt it, i'd suggest to the OP that he would need to find a way to heat up the metal no higher than 865 deg F.

I suggest to use a heatgun to soften up the metal so it can be bent around a mandrel that's the same diameter as the piece you intend to mount the heatsink to using whatever hammer you find works best.

Thankyou guys, i have a heatgun and a hammer and some minor tools smile.gif

I'm looking for some long heatsinks now, should'nt be too hard to find hopefully, if any body has any uk links i'd be greatfull.
Maybe something like these http://specialtech.co.uk/spshop/customer/Swiftech-Self-Adhesive-Mosfet-Heatsinks-4-Pack--MC21-pid-3723.html
Looking forward to some trial and error lol

As the heating up proccess with destroy the sticky i take it i'll need to order some thermal pads.
I remember i gpu cooler that came with a few longish sized heatsinks, fingers crossed google is my friend smile.gif

Once again thanks for the tips guys, i'm very greatfull

Trying to rep you guys but rep button does'nt work ?
Quote ect works.

Edit

The copper tubing idea sounds very good, i have a mate at aplace that could cur it down its center halving it, i could then use theremal pad to line the insde and then stick it to the motor, i could allso add flat bits to the copper so i could then attach something like these or copper sinks http://www.amazon.co.uk/Alphacool-7mm-Passive-Ramsinks-Black/dp/B008LZO5CU
?

Or i could solder the copper heatsinks to the copper pipe ?

I know you guys cant tell me 100% as ii'll be in trial and error phase, but you can advise me like you allready have smile.gif

I've found an interesting product that may adapt to your uses.

http://www.panasonic.com/industrial/electronic-components/protection/pyrolytic-graphite-sheet.aspx

It's quite expensive but would wrap around whatever surface you want to cool and perhaps lead off to a heat sink assembly......just a thought.

BTW......what is that your trying to cool?

Thanks, i'll have a look now.
It's a Thrustmaster t500rs, 3rd one, first burned out after 11 days, second would lose most its power after awhile racing, 3rd did the same, with teh added fans you see t means that the wheel initially loses alittle ffb strength as it goes from cold to warm but then it stays warm and power stays like that no matter how long i race for but with alittle extra motor cooling i believe i could make the small powerloss even smaller wink.gif


Edit,
The PGS Sheets are too expensive, i'm looking at round £10, fans allready cost a bomb so cost'sneed to be low, badass stuff that is smile.gif
