Hi SgaboLab!
Awesome video :) I'm trying to understand how it works. I think regular pc fan just blow air with no resistance, so the air flow is low. Even in your chamber air hasn't high pressure and speed of air is slow. For me, additional obstacle makes barrier for air, so pressure grown and it's make a better efficient for fan. Right?
Hi, no .. it works using theory of axial centrifugal compressor. Aerodynamic effect of the blade.
"The stationary blades slow the fluid, converting the circumferential component of flow into pressure." as far as i can understand, the speed of gases is converting into pressure. "The diffusing action in stator converts absolute kinetic head of the fluid into rise in pressure." so you used 3d printed part as a stator ? I mean, this effect is using in jet engines.
yes .. all right!! .. this is the theory .. I'm not mechanical engineer .. I tried different blade designs until found good result ;)
It Will stop the air from spinning like cyclone making it slower thus creating More pressure. Leverage.
@@ss-sq1hn I see now, yes block the spinning but the flow is the same .. works due to speed of air .. is aerodynamic effect.
This music made me go out, hunt and kill a mountain lion with my bare hands, then dance around a fire chanting to the ghosts of my ancestors.
:D
Really? I just chose to go out dancing naked in a grass skirt. Unfortunately I now must stay at least 1000 yards away from.a school zone.
Music is giving me a panic attack. Calm down!
:D
@@SgaboLab the music was very disturbing for me but the content is good, thanks.
The comment gave a good chuckle
Man, the music very instense, the papers blow with SPIRIT of the music
I just ran into this problem and this. looks like exactly what i have to do!! Thank you for posting.
Scott Hogan good ;)
IIRC, the flow for air is more or less incompressible at the speeds of these fans. What this means is that you likely want to calculate the total fan area and not make the cone exit much smaller than that, or you will load your fans significantly. You should be able to calculate the flow rates relatively easily (relatively being compared to compressible flow rates), and size your apertures accordingly.
hi, the cone is only to show the increase of pressure.
i set my pc on fire after watching this
Music make feel in an african tribe.
welcome to the jungle
That couples nicely with ur carbon filter video
Video seems to be glued on 4:34
ciao, yes. I cut a useless moment where the fan has disconnected from the power supply .. or something like that, I don't remember well.
isnt that just straightening the airflow giving a more efficient flow?
dance to the beat or else you will be eaten!!!!!!! aaaahhhhhhhhh
Axial fans are not made for static pressure just use a centrifugal fan
whats that for a music? i like it
You could show how you model it. I am interested also to print it for my fans.
It's a pressure drop, not boost! Converging nozzles are designed to take high pressure, low velocity gas and turn it into low pressure high velocity... Jet engines creste pressure in chamber then high velocity jet using such a nozzle
Basically creates a great vortex haha simplest explanation
Hello,
Would it be possible to make a model for those 120mm?
Greetings.
hi, already made the 120mm version .. pinshape.com/items/31800-3d-printed-pc-fan-pressure-boost-adapter-120x120x10mm
Is it possible to pay by paypal?
ok .. send me mail to sgabolab@gmail.com
good to find out this!
;)
Sempre il geniaccio prolifico...( ma il Cajon in sottofondo da dove viene?)
Ciao G.L.
grazie Gianni .. la musica l'ho presa dalla libreria audio di youtube, ora però non ho il titolo sottomano ;)
Would a having 2 stators one before and one after increase pressure even more?
ciao, sorry I read now .. no, add second stage require different design
Would this also function in reverse and create higher air suction?
ciao, no .. suction depends only by fan
Can you stack those units together to make it even more stronger?
ciao .. no .. in centrifugal compressor every stage require different blades and speed
Can this be used for an EDF-powered rocket weighing between 2 and 7 kilos?
hi, you can use same principle but need to design right blades for edf blades of the motor that you use ;)
i'm dancing with the music
;)
link for the music?
Hi SgaboLab I went to pinshape but it says "Purchasing is temporarily disabled due to a server issue". Is there another way for purchasing it (40x40x10 adapter)?
ciao, pinshape is broken .. I move to new shop www.cgtrader.com/3d-print-models/hobby-diy/other/pc-fan-pressure-boost-adapter-40x40x10mm
Bellissimo... L'unica cosa, secondo me il cono deve allargarsi, per aumentare la pressione statica... Stringendosi aumenta la velocitá dell'aria ma diminuisce la pressione statica
ciao, .. il cono é solo per far vedere la differenza con e senza adattatore ;)
SgaboLab ahh perfetto xD scusa, non avevo capito...
Sarebbe possibile fornire un modello parametrico per Fusion 360 oppure in Oscad così da poter variare l'angolo di attacco delle pale in maniera da adattarlo alle varie ventole? L'aria uscente dal rotore ha un vettore velocità che dipende in prima approssimazione dalla velocità delle pale del rotore (misurabile con uno spettro audio o in base alle specifiche della ventola) e dalla velocità del flusso (in base alle specifiche con una opportuna riduzione in base alla velocità di rotazione e alla contropressione). Grazie!
ciao, non uso quei prorammi e non li conosco
Can you provide me the CAD design for it . I could'nt find it on your thingiverse
ciao, is a paid drawing .. I updated the description links to new shop.
This isn't science. its sorcery! btw very cool.
:D ... thanks
AWESOME!
Science Man thx ;)
I am curious about quadcopter altimiters.
I am not sure who would know this, but I am asking everyone.
Does anyone know if a quadcopter will fly without altimiter?
You helped me a lot. Thank you very much!
Very interesting.
Thanks for the video.
Hi idk if you can or not but i really need a 80mm version of this.
already made .. link in description ;)
cool
whats name of the drum song pleas
"Firebrand" from youtube library
Hi SgaboLab, Is it possible to send you a question by email?
why you not write here .. ;)
Its reducing the hole but while velocity drops, its remains a higher ratio to area of opening that it was before, increasing velocity. This does not however increase static pressure. It increases air velocity. Static pressure is just how it sounds, velocity is a variable in the equation but its mostly a function of how dense the air is (how much its being compressed within the fan blades uppon exit into normal barometric pressure), this density effectively pack more of a punch. If you were hit with 1 cubic meter of heavy motor oil, or one cubic meter of distilled water, which one do you suppose will push you harder? Thats what static pressure is. You can use this fan in the video with an identially sized one on the same radiator, but the other fan having a higher static pressure, stock, and that higher static fan will push harder than this hack. Its like comparing a leaf blower to an actual super charger or turbo. Does it blow? Ya... Does it do what you would expect? No... Unfortunatly most of the printing community is filled with average joes who have no engineering, physics or chemstry education, no STEM at all, so we see a lot of bogus claims. Stay in school, kids. :)
So, you're saying pressure is why air has velocity? Unfortunately, STEM guys are filled with bogus terms and are clueless about market needs or what a market is. We go to a store and every manufacturer understands the word "specs" differently, but they all use one term called "static pressure", albeit again every single one with different units. I'd argue STEM is doing a terrible job in terms of guidance for the average.
You're right Bernoulli, about pressure concept... you forgot to say it's like putting your thumb at the end of a water hose decreasing the diameter!... however, think (if you are capable) about the results of managing fresh air into an area of your pc, in a better way as normal as it seems to be in this video. As a matter of fact: have yo ever built a computer?? with your own budget?
someone will ask you for constructing a jet engine
BaguSadikin :D
Haha, wish i had a 3d printer, my rig would be cooler then.
Did you need to put that drum soundtrack in this video? Irritating as hell.
Just use a edf 😎
Do you sell 120 / 140 printed?
i do
@@alexdantalian would like to buy 2. Where? Best regards d
ciao, sorry no .. you can search someone that have a printer near you .. and check how much for a print .. only then can you decide whether to buy the 120mm drawing .. and sorry, no 140mm version.
Is this design used by any existing muffin fan manufacturers?
no, that I know of
All you're doing with the insert is further restricting the airflow which increases the velocity (not the volume or pressure), which is why the paper is moving. The exact same result would be achieved by using a smaller nozzle.
Don't agree, overall exit area (tip of cone) is the same as before.
seen that for years in old premade computers...
not new
those are called air grilles .. are different things :D
No the cones to increase pressure .
?? ... "cones to increase pressure" .. ?? ... sorry but no ... the cones block air flow ;)
yeah sure...
There are some fans in old server PC-s that have this design built into them, and they are twice the thickness of a normal fan.
(search for intelli station z pro fans - those are for cooling HDD-s)
Just saying: a nozzle like this will DECREASE static pressure. It will increase DYNAMIC pressure ;) If you want to increase static pressure, you gotta built a diffuser (and slow the air down) , not a nozzle
I doubt, the dynamic pressure is that exerted on a moving body .. where do you see moving bodies?
The fan generates dynamic pressure on the blades and transforms it into static. My adapter does the same thing, the process is dynamic but the result is static. Look at the other tests.
@@SgaboLab no that's not how it works. Look up Bernoulli's principal. Dynamic pressure is simply the part of the total pressure that is caused by the velocity of the fluid. Has nothing to do with forces being exerted on a body (of course IF you would put a body into the flow, the force it will experience is a result of dynamic pressure).
If you don't believe me, you need to educate yourself. Look up nozzles and diffusers of ducted flows. I have a degree in this stuff so I know what I'm talking about

I just pressed m
Holy guacamole your printer is loud.
This music is so intense!
Kinda blows...
