New concept for waterblock design: Heat Pipes - Page 4

post #31 of 78
thats what I meant right now they are flat, thus maximizing S.A. replacing the fins with heatpipes of less S.A. would only damage it's results. And yes I man pretty sure heatpipes work best when upright, it makes sense thinking of hot air properties

But the fins are restricting flow far too much ... spiraled heatpipes would allow better flow then the current fin setup.

As for more surface area, I was referring to the heatpipe surface area alone ... no fins involved whatsoever. Spiraling the heatpipes would cause the flow to spiral while at the same time allowing "more" heatpipe to inserted into the same confined space as the simply vertical heatpipes.

Perhaps a heatpipe with a wick to maximize and better direct the effects ?

but a heatpipe spiral would have water just fall through am I not correct? which would minimize the time which it is transferring heat

Some users speculate that the orientation of the Heatpipe could affect its performance, given the theory behind the heat pipe this is actually not a bad assumption. In fact, for industrial applications, the design and orientation of a heatpipe would be very specific to maximize performance. But in a CPU or video card cooler, the impact may or may not be as significant.

What we've found at Neoseeker during our reviews is that whether a heatpipe based cooler is standing upright, or standing on its side, the cooling performance difference is less than 1 degree Celsius - so in our real world testing that sort of orientation difference does not seem be a huge factor. Temperature differences resulting from orientation were slight and are likely the result of variations in the test environment.
From this, I'm willing to guess that the material as well as the thickness of the pipe would have more impact than the orientation.

Also, from my understanding of the physics involved, ( which is small by far to alot of the peeps in this forum ) residence time doesn't appear to be as relevant in water cooling as I had thought ... due to the closed loop conditions. I'm sure ira-k could explain it alot better than I.

haha time absolutely has a factor think about when you burn your hand, if you touch something for just an instant, you won't get brunt badly, if you leave your hand on a hot stove for 20 mins, your hand won't be very useful anymore....

there is no use debating this anymore really, lets just call it a draw

I'd use it, if the reviews and benchmarks showed it was a top performer. I've had a look on the net, but so far I can't find any reviews for this block. Anybody find any reviews or benchmarks for this yet?

Myth: Water must slow down to fully absorb heat.
Reality:
In a closed loop, a given water molecule actually spends the same amount of time in the radiator, no matter how fast it is moving, as long as the water is indeed moving.
If this is a difficult concept to understand, think about a race car on a track. If the track is one mile (5280 ft) long and the car is driving at 60 mph, the car will spend about one second in a 100 ft stretch. Think of the 100 ft stretch as the radiator. If the speed is doubled, the car only spends ½ a second in the 100 ft section, but it passes through that same section twice a minute, so it spends a total of one second in the 100 ft section per minute.
More good information on that page too. I knew I'd read it "somewhere" but couldn't remember where.

in fact, the faster it goes trough, the better the heat dissipation. transfer of heat happens much faster when the 2 involved materials have a higher difference in temperature. if you slow down the water to warm it up more, it wont absorb heat as quickly, thus resulting in higher CPU temps.

I was wrong earlier - the heat pipes don't need to be changed, the water flow needs to be redirected. I have a few ideas, and when this thing hits the market an bombs I may have to pick one up cheap and get it working right. Would need a good pump though, nothing that I have currently will do....

Were not radiators....
