Thor, or should that be Zeus?

Can anyone recommend me a nice simple watercooling solution for the 4KW Spindle.

I had considered something like:-

6mm fish tank tubing (size to be confirmed)
Small fish tank pump
Some form of container that allows the heat to leave the cooling cylinder.

Ive seen some elegant solutions that use a CPU type cooler for a closed loop system, I am all ears ...

Thanks

Something like this (With fans stuck on it) would work well

Simply splice the radiator into the return.

Thanks. Certainly an option.

I like this too, not sure how adequate it would be on a 4KW Spindle.

I would worry that's underpowered but I also read you don't need a lot as the spindle are pretty efficient and don't make much waste heat. I'm going to use a 2.2kw spindle for maybe up to 10 hours per day 5 days a week I'm hoping a 200l barrel will be enough on it's own but if need be I'll use one of those heat exchangers I linked to I can get them much cheaper than that link from scrap yard friend so if you ever want one just PM me and I'll sort it out.

I'm only going to use a maxijet pump (Aquarium style) but it'll be fine as long as the head height is enough (Which it is 2m's) but will need to reduce it for the spindle (13mm standard hose pipe on pump)

The heat exchangers are 25mm pipe compatible

These fans are pretty quiet and pump a lot of air also cheap!

Just drill some holes in the fan casing and cable tie it to the radiator it's probably best the blow through the radiator but even if you suck I bet it would work great.

You can fit 2 5" on the heat exchangers but 1 6" would be fine on it's own.

It seems most get away with 20 litres or less. Your 200 will be a massive overkill.

Ha ha ha now I take that as compliment from the man who's building his cnc machine from concrete and called it after either a norse god with a big hammer or the god of war lol.

I have the space and the waterbutt so I figured why not ;)

But in my case, more weight (within reason) = better damping. You aint going to cool the water much more :-)
