Copper sheet as heat sink

[200T]

Hi!

I found a large roll of copper sheet (0.6mm I think), as used on roofs etc. - turned out to be realy helpfull as a heat sink, as you can easily turn it into any shape you want...

So yeah - I find copper sheet much more practical than copper blocks, as it's felxible and easy shapeable. In the picture it's hard to see, but I had to close a gap of about 1.5mm on 1mm sheet metal - with block I wouldn't have had a chance. With folded copper sheet it was a piece of cake to close the gap

And if you need a large block - just fold it over a fewtimes and you have one - you can then later recycle it for smaler pieces etc.

Should also be easyer to obtain than large blocks of copper.

Maybe it's a little help for someone else, I thought I post that here. As I myself was always recommended to use copper blocks. But I'm most probably not the first one with that idea

Regards,
Jan

Copper blocks are great - but not always practical on vehicle bodywork, have used similar myself - 80's Japanese not the most consistant to weld.

I do a similar thing, I got a fairly short length of copper central heating pipe offcut, I've got one piece that I've hammered down to oval, and another I've cut along it's length and flattened into a sheet.

Now I just need something to remind me that when I've been using it as a heatsink, it will be hot.
