We could have heatsinks like this if it weren't for capitalism

It does almost nothing compared to even a single low speed fan

Go to fucking Venezuela you fucking dirty commie

I haven't yet found the paper with the linked image but there are a bunch of other similar papers. Looks like there's a lot of work going into this topic, pretty cool
I'd bet you could run the optimization process with simulated air flow as well. It feels unlikely that it would generate a typical bladed design

>Topology Optimization, Additive Layer Manufacturing, and Experimental Testing of an Air-Cooled Heat Sink
Paper shows results that their 3d printed coral performs a little bit better than blades, and that the gap shrinks but doesn't go away with more air flow.

These things look hard to manufacture, though. Probably only 3d printing, or maybe you could cast it. Is it even viable to 3d print materials with good thermal conductivity?

That looks like it would be stupidly expensive to manufacture, might as well just go for an AIO watercooling system at that point which would be an even more effective cooling solution.

Could you link it?

Yeah but at least we have food

Could 3D print one, put it in thick sand to make a mold and then cast it in the sand

Looks are deceiving, especially when you don't know anything about manufacturing. Could easily be made by casting aluminum in a sand mold

what if we grew them

Except that is simply not true. If a product is effective then it will make it to market. This whole thing looks terrible mediocre cooling. Extreme manufacturing costs due to complexity, I would hate having to quality control or ship this hunk of garbage.

>If a product is effective then it will make it to market.
do you like actually believe this or are you shitposting, i can't tell

>LITERALLY projecting
pathetic

Belief is unnecessary it simply is. No number of wackjob conspiracy theories about free energy and the ebil oil companies hiding it from your will change that fact. You need to understand that your weed addled mind has a fundamentally flawed world view and you have used a mythology to do so. ok friendo. seek some help.

they're insecure and can't take a fucking joke
what else is new

>n-no y-you
stay butt angled my kid. lmao

If a product is effective, it has a market base. Period. Only a socialist (retard) could possibly claim there is no demand for quality products.

If they were better than what's on the market, then they would sell. I don't even think they exist and have yet to see any proof that they're even close to than a cheap noctua setup which is virtually silent with the fan on full. Not sure what the point is of this coral-looking guy.

Which is why Chinese good are always a superior quality.

That's only for passive cooling and is way less efficient than anything with a fan

doubling down on seething isn't the move here retard

>profitable
>quality
conventional heat sinks are not expensive to manufacture and the quality isn't hindered - they're made of cheap metals arranged in simple ways for obvious reasons. Maybe you could name a product for which your distinction is relevant?

Still a better solution than communism

do you know why they're getting worked on? I can't think of a case where you need no airflow, and surely other arrangements are better when air is flowing over them

based

Why is valid advice perceived as seething? This post alone has the potential to be the catalyst that positively impacts the lives of many.
I think you're overreacting a bit.

Hey man, give him a break. Shoving bags of dicks up his ass is his favorite activity, he IS a Communist after all, the poor retard can't help it.

How much efficiency do you lose from slight imperfections and deviations? I know those neural-network/machine-learning generated antennas had some whacky performance losses from even miniscule deviations from ideal.

Why wouldn't someone believe it? What do you feel is so far fetched about the concept.

So what, OP? Explain why that is a bad thing, it looks horrible

OPs is cool because it causes natural convection, but that's not the only reason you'd use coral. The paper I referenced seemed to optimize for getting the best performance out of your air flow, and one of the things they looked at was the pressure drop across the heatsink.

It seems intuitive that you should be able to just optimize surface area and call it a day by building some kind of fractal heatsink, but these papers seem to be saying that it's more nuanced than that.

For reference, this is the design from that paper. They put the fan in the center and blew air outwards, and I think they're claiming that the pins get placed with some kind of aerodynamic profile based on that.

Does the paper mention anything about using it with phase change technologies. I imagine if every nodule on the coral was feasibly the end of a heat pipe a difference could be made. But again that's an even more complex manufacturing process making it all hollow and sealing the phase juice in the structure.

>it weren't for capitalism
If anything, capitalism will get us heatsinks like that because companies have to innovate to profit.

That's really cool, seems a lot more useful to model with with the fan in position. I wonder how long it'll be - if ever- before this goes full consumer and some PDE solver program makes you a custom shaped one based on what you've got in your case already. Probably gonna have to be long after the invention of some household printer that'll work with metals but now I'm just getting into intellectual masturbation

The heatsink in your picture is bullshit though, unless it would be made out of solid silver or copper. Even then there are thermal bottlenecks wasting airflow over space usage.

ugh... what's a heatsink?

>People still believe this

so what happened to Kodak, HP, etc. ad infinitum

As many have pointed out, if a heatsink design like this performs well (relative to the effort it takes to make!), capitalism will make it a thing through companies competing to make the most profitable product.
Another thing would should be mentioned though, is that the alternative to that is... what? The GOVERNMENT deciding the path of technological development? THAT WOULD BE INSANE. Fucking brain dead bureaucrats basing their decisions on farts and unicorns rather than market performance. No thanks. All that communist countries are capable of is copying from their betters, no capacity for innovation.
Go jerk off to AOC's tits ya commie faggot.
