Building the Ideal Heat Sink

I bet that would make an awesome water block.

amazing

What boundary conditions were used in the competition? Any response would be greatly appreciated

Can I invest in this?

Heatpipes still will transport the heat hundreds times faster

Coolness

is there an absent airflow design version of a 3d printed heatsink but can still spread and dissipate head effieciently?

I'm not an engineer but I can tell you that 'keeping the air in the heatsink to extract more heat' is BS. He's saying that coz he doesn't know why the simulation produced the curve. Heat transfer works better the higher the temp difference.

electroboom needs to have a chat with this guy about his eyebrows

honestly it would be much better heat sing for passive aplications
heated up air will travel up sucking air trough opening on the bottom
because there is an expansion chamber on top heated air will decrease its pressure allowing for more air to be sucked

Плохой вариант, загрязнение не очистить.

This made of copper mid be the best

The indian guy has a even thicker unibrow that Mehdi (electroboom). Mehdi should be ashamed :P

Their heatsink looks awesome and it apparently does a great job too. I hope these kind of heatsinks will be available for consumers soon.

wouldnt it be much smarter to use a more heat conductive material instead?
Like copper or Silver?

bro, takes 2 seconds to shave your monobrow

Welp ........There goes my idea. Its already been done.
Sigh...

Better speak about the construction materials and let aside the shape .............. probably copper is the only efficient one

Copper transfer twice than aluminium, big companies can make pure copper heatsink for pennies.

pfft, who needs air cooling when you have ln2 and ln2 pots, pfft pfft

Part of engineering is design for manufacturing. This design is great for one off designs, but is more complex. See heatsink skiving

Why add unneeded static pressure channels, eddy currents, and most of all why add a fan blowing from top to bottom when heat naturally rises. Highly inefficient looking design. Thats pretty much all thermal mass anyways.

Excellent work.

"topology optimization" aka keep pressing buttons until it looks cool.

If you really want to make an efficient heatsink then you would need to use fluid dynamics and AI.
Humans can only do so much, and we're not very efficient at calculating fluid dynamics or all the variables that affect it.

imagine trying to clean dust out of this

Nice design
Kindly share your email, I am having few queries on the same. I am working on similar aspect in different segments

What exactly does this heatsink optimize? Is it optimized for getting maximum cooling for an arbitrary airflow? Would a different profile work better if you tried to maximize cooling for the amount of noise generated? I would imagine that minimizing noise is more difficult since both the fan and the heatsink profile might contribute to both the cooling performance and the amount of noise generated.

I borrowed the prototype and it melted all over my processor. Now, my fan is stuck to the motherboard.

>Optimizing these heat sinks

>Using aluminum

Ya blew it.

this guys never clean a cpu dissipator.

The one that doesn't clog with dust always wins.

This makes no sense whatsoever.

But in the design process you should also take into account how easily it can be cleaned. I am a computer enthusiast and I disassemble computers on a regular basis. I can say that most of the designs I see are dust traps that in a short period of use will have the very opposite effect. The heatsink will be clogged with dust and the temperature will start to rise. And there will be no easy way to completely clean it. Actually, it will be impossible to clean it, except with the use of an ultrasonic bath cleaner that not everybody owns. And let me tell you that if it is not thoroughly cleaned to be like new, the dust that remains acts like a glue for other dust particles to re-stick on it and accumulate quicker than the first time. In recent years I have noticed that designers do not take into consideration all the parameters of real-world use but also the effect of time itself in the designs of their products. For example, they design a bathroom faucet that may be beautiful in terms of elegance, but in terms of use it is not at all practical because it is not high enough in the sink and to wash your hands you have to touch the walls of the sink that may not be clean. So, you intend to wash your hands and instead you get them dirty (opposite outcome...).

i donno... that does NOT look any better than my noctua d15 or even cheap intel cooler. first it has such little surface area and such restricted airflow. where are the test results?

Large surface area, high thermal conductivity, cheap as peanuts. Copper wire? 300 meters thin copper wire for 100W CPU? Will be more than enough to cool it passively. Mechanical engineering as your guest.

That’s why tech companies should be led by engineers and not business, legal or marketing people: to enable innovation and advancement to lead the way and speak for itself. Engineers walk the talk.

Its a turbine, well thought

Do you have a parametric model of this that can be scaled for various applications and form factors?

STL?

What kind of material would be used that can be 3D printed?

Does it work the other way? If it was being actively chilled, could you blow air through it and expect it to pull enough heat from the air even in the short time the air spends in contact with it to be an effective small personal cooler?

bet it is 20w tdp lol

Finally some good heatsink to my overclocked Core i9-10900k

You guys are awesome. I cant wait to use a computer with your heat sink.

Okay, so that's not going to fit into a laptop. They need to demonstrate solutions optimized for various common form factors.

Nice video

I would sincerely appreciate it if you would make me a VRM heatsink for a 2080 ti. I plan to mount an NH-D15 to the GPU, but I want a cleaner heatsink than what’s available online. I’m willing to pay.

That's really similar to a Brachistochrone curve
