why...the fluid can sit, cant it? i dont see the problem with sitting fluid that you replace every 6 months or so
the fluid is like a medium that the heat gets spread across, and the fluid gets cooled and heated in sucession. it is a diversion for the heat, no need to pump it.

the fluids need to be moving, other wise the fluid at the base that thing would heat up, all fins on the side would be useless unless there is hot fluid moving by it being cooled, it is just a big radiator
the heat of the fluid at the base would transfer and move along the rest of the water until the temperature of the entire system reaches an average. the cool rod cooler would bring this average down and dissipate the heat from the water out the sides lower the average temp of the system and lowering the CPU temp.
i really dont see why it has to be moving

i dont see the point of the fins if there is going to be a refrigeration tube? thats basically just water cooling i guess?
although.. if you remove the cooling tube, keep the fins, orient the HS tube vertically and make the tube more shaped like:
__
then the problem might just be getting proper flow of the fluid. and also choosing the right amount of the fluid with the best dissipation or rise/fall rate. but who knows how much better that would work than just a passive hunk of copper... it also might collide with power supplies

with refrigerant as a coolant you don't necessarily need a pump. A/C units everywhere don't use pumps because refrigerant moves on its own due to its low boiling point. A/C units use compressors to keep the pressure of the refrigerant up(lowering the boiling point) and in a liquid state longer it just happens that it also moves the gas in a more rapid state(its just an overrated air compressor). Believe or not refrigerant is boiling hot when it cools!
The systems illustrated would not work because the refrigerant will always be in a boiling state. In "theory" it could work but you need some way of getting rid of the heat, if not, you'll end up with a frozen coil in no time. R-22 at sea levels boils at -17C. At typical home a/c system is running around 230-255psig on the high side keeping the R-22 around 46C-52C. The low side pressures are around 60-75psig which means r-22 temps are 1C-7C this is what you "feel" coming out of your vents at home during the summer time.
In order to effectively use either of the systems illustrated you'd have to find some way to subcool the refrigerant after it passes the cpu.

This is about a simple as you can get when it comes to refrigeration:
I refined the idea showing the heat waves and eliminating the heat pipes. It is an everlasting cycle and the fluid is just acting as air, therefore there is no need for it to be pumped. It is cooled, heated, cooled, heated etc., an everlasting cycle that ultimately keeps the CPU as cold as the average of ambient+refrigrerator tube+CPU. Multiple tubes can be added for more effect. The fluid is not refrigerant, just a fluid similar to water. The tube is what provides the cooling, and it is internal.

You can get a 3" diameter foot long copper pipe for around $25 on ebay, you can then get a small square of copper for i'm estimating $10, then you have the refrigerant and other equipment which is probably gunna end up costing you around $50, so $85 for a home-made cooling system isn't really great......just go with water cooling, its much easier.

There is your problem, there is no such thing as a tube that can constantly keep itself cold. I think what your trying to get is a peltier cooler is tube form, but still that requires other fans/watercooling and electricity.
As for the 'cycling' of the water (or refrigerant) your trying to do in the heatsink look into oil cooled computers. Where they place a whole pc in non-conductive oil and let the oils natural heat dissipation go into action (the rising heat and falling cold your wanting).
Finaly, I hate to burst your bubble but they already have put these two together. Its called heatpipes.
no worries, no bubble bursting lol. just trying to get ideas out there, not attached in any way
and the heatpipes do this with vapor and air, not with running liquid which has a much higher specific heat capacity and would yield much better results
85 bucks is perfect. it could cool better than air, but not as good as water, however good water cooling costs double. So actually its a great medium solution

ok so how are you going to get the heat out of the refrigerant? If you can't get the heat out of the refrigerant you're going to end up with on big block of ice

Heat pipes vaporize a fluid at the heat source and condense it at the heat sink, so it isn’t single-phase transport and therefore is a very good method of heat transfer. As for your design, what exactly is the “refrigerating tube” (I’m assuming it is some sort of active cooling) and why not put it in direct (or close) contact with the CPU? The water isn’t going to do much using natural convection; you’d be better off using solid copper.
