LIQUID COOLING PUMP AND FAN COMBO.

Introduction: LIQUID COOLING PUMP AND FAN COMBO.

About: 18 years working for Thermacore Inc. but, now unemployed. I work with my wife running an at home day care and Ebay store which are both doing pretty good. I am a part time artist (for the most part self taug...

I worked in the electronics cooling market for Thermacore Inc. for 18 years building all kinds of heat pipes, vapor chambers, thermosiphons, air to air and liquid to air exchangers, pumped liquid cooling, heat spreders/cold plates and loop heat pipes for high & low power components. This is an example of one of my ideas and was not a product of Thermacore. If you have any questions about electronics cooling ask me here or at disturbeddesign@yahoo.com .

The idea is basically a custom made pump housing with impeller and magnets on the underside of the impeller. Then a normal 120mm computer fan also with magnets mounted on top of the blade assembly. The pump assembly is mounted on a fan guard and then screwed onto the fan. So when the fan is running then so is the pump. So now you can run your liquid cooling systems fan and pump using only one motor plus make the whole thing from easy to find parts and if you are a DIY then you most likely have these parts. The only thing I needed to get was the magnets which may be about $2 dollars worth. I did test this unit based on test data from a high performance liquid cooling system for a high end high priced gaming computer. The pump & fan combo pictured was tested with a water block and exchanger which is no longer attatched.

If my instructions are not complete enough feel free to e-mail me with any questions. Test results are on the following instruction pages. Thanks for looking and have fun. I do have to say though buld it at your own risk I cannot be responsible for damage to yourself or parts you use. I have included a rar. file with the same instructions and more pictures.

Step 1: Step 1

My instuctions are part of my picture so if you print or save you will have picture and instruction on one page which I think will make it easyer if it is printed it is all there.

Step 2: Step 2

Step 6: All Steps and More Pictures.

This is a RAR. file with all instructions and more photos and again have fun, be safe and make a profit if you can. This was my own original idea and in no way was part of or referenced from other sources not my own. e-mail me at disturbeddesign@yahoo.com with any questions or comments. I will be glad to help.

    There is only the one pictured. I never took it any further than the prototype.

    Your comment: "because I made to much an hour and the company sales were low" is interesting. Either I understand that your productivity wasn't worth what your employer was paying you, or that your position had become redundant. Because this is ambiguous, could you clarify? L

    No it was because I earned what I made But, The company was loosing $10 Mill a year under Modine Manufacturing's Reign. The company was now up for sale and some of the original engineers of Thermacore was interested in buying it back So before they bought it back they when after anyone who were making good money and close to there 20th year and they forced us out. It had nothing to do with my performance I could run circles aroud any one who worked there and was sued a year latter from them because I write some papers on electronics cooling including powder recepies and they did not have me sign a non-disclosure when they forced me out.


    Such is the way of business these/those day, thanks for the detail. Did you manage to beat the legal action against you?

    L

    Sort of, They wanted what they sould have paid for when they forced me out which was my signature on a non-disclosure. There suit was frivoulous but, I could not get a lawer or even pay for one and they knew that so I signed a non-disclosure. From what I have read that a non-disclosure or non-compete is only good for one year in any state if it keeps you from getting work in that field. So I am not worryed about talking about electronics cooling and what I have learned it's been over a year since the law suit.


    Could have been worse then, thanks.

    L

    Yeah, But I still have trouble getting over it every day.


    I learned to stop caring...

    L

    Yeah, That's what my dad said when the same thing happened to him. I will have to learn to do the same.

    foreverdisturbed you are froeverwelcome on Instructables.

    Thank you, If you have any questions about any electronics cooling products feel free to ask. Heat pipes, Thermosiphons, Vapor Chambers, Air to Air or Water to Air Heat Exchangers, Pumped Liquid Cooling, Loop Heat Pipes. I have built them all and not afraid to tell you anything that no electronics cooling company will not. You can E-mail me at disturbeddesign@yahoo.com


    That was Feb 2009.
    I was interested.

    Hi, nice design! I'm wondering about the magnetic flange: I once did a pump with a much larger magnetic-flange to "demultiply" the magnet's forces vs the torque implyed. The magnetic field must be really strong while starting the pump, and to keep the pressure/flow at a decent level, you must have A LOT of those magnets. But the magnetic field is then turning into a "whole" field due to magnets being close from each other, and since the magic between magnets is working at a 90° angle from the rotation axis, I never had a "virtual" drive-shaft working properly... But the thing behind this is a completely sealed enclosure, that's more than excellent, wich is pretty much what a computer wishes when fluids are involved..

    It was actually a very simple design. I think it was just six or eight small 1/4" dia. magnets on the top of the fan and the same on the bottom of the impeller.

    The only problem I had which was not at start up but, at the amount of voltage applied. I was only able to run the fan at 8v instead of the normal 12v because if it ran to fast I would loose my magnetic connection. I am sure with more attemps I could have improved that by adding more magnets and decreasing the space between the impeller and the fan.

    I was able to test this on the same test fixture used for the liquid cooling system Thermacore made for Alienware and it did not perform as good but, it did pass on the high end allowable for the Alienware system. I am sure if I could have got it to run at 12v I could have matched it..

    I'll try to find rectangular magnets to change the magnetic field attributes.. or hard-drive magnets, they're killers.. But therefore the pump's size will suffer "big".....

    I also when I attatched the magnets I staggered the polarity north/south every other magnet. I did this on both the fan and impeller. This sort of locks the two together.

    hey foreverdisturbed, what kind of pump did u use? was it some kind of vane rotor pump or centifugal pump? or does the actual pump design not really matter. Please get back to me soon. thanks, allen.
