Liquid Cooling Using.............

By Goggle Eye ·
I appologise if I am in the wrong area.

I was reading about cooling a liquid cooled system using antifreeze. I found it vary interesting.

I was wondering why you could not use windshield washer solvent for liquid in your cooling system? Please do not ask me the chemical make up. Should be inviromentaly safe, doesnt hurt you if you get it on you. Now warning labels if you swallow the stuff.

Algae does not grow in the solvent.

Does not effect rubber hoses or plastics.

Does not stain your skin or clothes.

Does not hardly evaperate.

Should diapate heat vary easily. About the same weight as water.

Will not foam up or make when under pressure.

Will not require any additives.

has a high tolerance to heat (engine Compartments) when it comes out of the washer sprayers it is cool to the touch.

Cheap on sale in most dicount retail outlets, grocery stores, convienience stores and gas stations not to mention auto parts stores. Around $1.75 galllon.

Has a nice blue look.

Not sure what would happen if you added a lot of food coloring to change the color from blue to lets say red, orange or green?

What would happen if it was spilt solvent on your hardware. Should clean up like water.
I guess you clean it out by using some kind of air duster. When you use a new can of air duster if your not carefull it will make everything vary cold and wet.

I spilt regular cooling liquid in my computer case by accident and aal over the top of my desk including the key board. Could not get the coolant cleaned off the hardware it just kinda rolled around and made things worse.

I dissasembeld the computer, power supply and key board, fans and computer case thru it all in a bathtub full of hot water. Washed every thing with a cosmetic brush (no soap) dried every thing off with a hair dryer. Put the hardware back togather every thing is working just fine. with out issues.

I am building a new computer liquid cooled system. I do not want to mess with water or some kind of pre mixed coolant that has to be changed once a year or when ever. antifreeze will last up to 5,000 hours or 100,000 miles easily.

Well I hope you respond and any comments I would appreciate.

Yep. Wrong area. You want Q&A.

Well, windshield washer fluid is not designed as a heat exchange medium, and the pump probably isn't rated for washer chemicals. Maybe someone here could tell you for sure, although you'd probably find out more at a site and forum dedicated to modding and liquid cooling.

While this is most defiantly in the wrong area

The answer to your question is that the Antifreeze change intervals will remain the same for any coolant that you use. While you can change the chemical makeup of the coolant it still needs changing at regular intervals and the year mark remains about the right time to change things before things start to go wrong. Any longer and it gets forgotten.

To the rest of your question about using windshield washer solvent if it is water based you can use this just like any other water based product. You can not use other products in these systems because of the Viscosity Issues that arise and the problems associated with turning the liquid to a gas which can cause air locks in the Hot Parts of the Liquid Cooled System stopping any cooling at all and possibly resulting in an explosion as the pressure builds up. Steam occupies 812 times the volume of the liquid that made it so if you have 1cc of liquid boil off it takes up 812 cc of space. If you get a pressure buildup because of this happening it doesn't take much liquid boiling off to create an Pressure Explosion.

As for changing the colour of the Liquid all depends on what you use to change the colour. Food based coloring and Solvent Based colorings should be avoided at all costs as they will have adverse impacts on the system.

The big advantage of using the supplied coolant is that it doesn't Wet things as well as water so it is designed to roll off the Circuit Boards if there is a spill/leak without wetting the surfaces. The down side is it behaves exactly as you described above and should be removed by placing a rag over the spill/leak to absorb the liquid.
