using car parts for pc cooling

[mizzou]

Anyone ever used a vehicle water pump to push water on a pc cooling system? All it needs is a rotating device, tensioner and belt to drive the pulley, rest can be ghetto rigged.

Thinking about doing something crazy with a spare box oi have laying around

ummm... those pumps are by delphi is im not mistaken.
On american cars im fairly sure its delphi.

Delphi is a company of Laing Industries, as far as i know, unless this changed.

So the pumps we use in current hobby should be simular to Automobile pumps.
It would work, seeing how both should be a 12V pump, but i would need to look at the stats on such a pump to tell ya how effective it will be.

you want 140gpm ? Why not use a small electric pump ? You could use one of these but you better have a huge radiator and large plumbing or its gonna make insane pressure.

the water pumps I'm thinking about are just driven by a belt causing friction on a pulley, so it's only going to pump as fast as that belt is spinning,

no voltage required other then something to drive the belt

Iron + poor efficiency = bad

Once you reach a GPM you get very diminished returns anyways.

correct me if im wrong, but you would need a motor to turn the belt.

And im sure thats less efficient then a mag driven pump @ the same noise.

Cant you do something innovative like base the cooling on a sterling engine that uses the heat from the PC or even employ a liquid convection system (hot water rises & cool water sinks) for circulating? You might even make it into PC magazine or Tom's Hdwr specialty computers.

I'm just looking to do something "cool"

I believe most of these are just aluminum, I don't think there are alot of cast iron water pumps except for maybe old school ones

besides, you just hook the thing up to a heater core for cooling circulation and you are good to go.

are you insane?

Think of it more like functional art! I could have a case built out of aluminum....a frontgrill housing the heater core and behind it a fan shroud to pull in cooler air just like a car.

On the inside, a pulley powers a water pump that keeps bith cpu and gpu nice and cool

I wonder how large this case would have to be....

Moroso makes a electric pump conversion kit for mechanical pumps. Hooks up with a belt and bracket. Most of the electric pumps on the market could in thoery be PWM driven down to much lower voltage but your still going to need a good deal of current and alot of flow. I personally would look for something entirely different. Unless you want rediculous performance. Which you will get.

If you're really going to go through with this, keep a couple things in mind. Automotive water pumps are spec'd for about 3000-5000 hours of use. If your PC is running 24/7, that's only about 7 months (best case scenario) if you're starting with brand new.

Secondly, despite their name, you'd want to use actual automotive coolant (50/50 glycol) to even get that 7 months of continual use as it has much more lubricity than pure DI water (which has more lubricity than tap water).

Back in the day I tried using a dishwasher pump for my WC system. Worked really well, perhaps too well, as I could never get the thing to seal right even at low RPM. Needed about 500rpm on a 200w electric motor to get any sort of pressure, but it would ramp up way too fast.

Would be very interesting on a large system, like a house-wide setup cooling multiple machines over many floors/feet.

for something like that I would just create a low flow regulated waste cooling system from city water supply.

It may be fun for a novelty idea to make a "mister bone stripper" type mechanical contraption with serpentine belts, etc. Not very practical or reliable as previously mentioned. The MTBF of automotive water pumps is prohibitively short for continuous use.

You could however, use an open drive hot water circulating pump that would more or less give the same "feeling" and be much more reliable.
