Amplifier water cooling project!

Otherwise · 24th July 2003, 06:37 PM

If you're interested, here's how I'm putting my water cooling into practise. Cheap

I bought a (my95-97 or something) Nissan Micra's heater element for 15€ (15$ or so) and i'm going to use it as a radiator. The whole system is gonna be cheaper and more effective than those computer water cooling kits (I think

). The class A amp I'm building dissipates around 60-80 watts. The radiator doesn't heat up at all when it's heated with a ½ kilowatt hairdryer, so it should be effective enough.

I made a water cooling block from 45x45mm steel profile. The end parts are 5mm aluminium and are going to be glued in the ends of the steel part. The copper pipe(s) are going to go through the alu end parts, which isn't exactly good because of the corrosion

I'll make some holes in the copper pipe(s) so that the water spreads evenly in the steel block. Pvc tubes are then connected to the copper pipes and the water is pumped around by a 14€ garden pump (you might think that it's noisy but it isn't. Amazingly silent

).

Ok. here's the block. More pics click the links.

Interesting, how does the radiator loose it's heat?

Kepis,

Convection?

Otherwise · 25th July 2003, 05:34 PM

Yep, convection. If needed, I'll put a 80x80 fan in it. But it won't be necessary. The system is going to be tested tomorrow, when all the parts are together.. I'll heat up the block with a pencil torch and see how the fluid cools down.

Test went ok.. I tried to warm the block up with a 1200 degrees (or something) bottled gas torch, and the result was that the block heated to something around 50 degrees celcius (I think). Dindn't go any further.

Unfortunately, the water tank is made of plexiglass and didn't stand the stress of the tube joints which I screwed in..

Must do a new one.

Some pictures are coming when the system is running again

Thanks,

Please keep the info coming. This could be a cheaper way of making a class A SS amp.

Cheers,

Had a little break..

Now going on again, if someone is still interested

Now all the components of the system are tested to fit in the case and I'm finally welding the amp itself. (My homepage is full of stuff so I put the pics straight here until I manage to find more space):

Hello!
Tai vaihdetaan englanti suomeen

Pari kysymystä esittäisin.
Mitä A-luokan vahvaria oot tekemäs? Paljos tulee hintaa tollaselle jäähytysjärjestelmälle? Vaikuttaa kyl mielenkiintoiselta.

Otherwise · 23rd August 2003, 02:17 PM

Sellaista todella yksinkertaista (tuntuu välillä, että itse vahvistin on sivuosassa tässä projektissa

)

kytkissivu

Suunnittelija on Petri Pykilä, ja osat hain Tricompista. Jäähdytyksen hinta lienee syyläristä ja vesiblokin kalleudesta riippuen jotain 15(syyläri) + 14(pumppu bauhausista) + 10 € = about 40€.
Täytynee tosiaan laittaa kaikki kuvat ja jutut jossain vaiheessa kotisivulleni jos tilaa löytyy..

Millä nimellä muuten liikuskelet Hifilehden foorumilla?
