yeah so this is an example of what makes it special yeah so here we are actually
pooling a very large hot spot so this is a single radical dart 25 by 32 millimeters
and we have basically heated up one ninth of this essentially at 10 millimeter by 10 millimeter
rectangle yeah with 402 watt per centimeter square which is an extremely high number yeah
and we're using phase change 10 which is about point of six and we're showing that we can maintain
junction temperatures of about 94 degrees and the thermal resistance of our device of
just our liquid jet is about point of five now comparable solutions in the market today
they can get about 300 watt per centimeter that's the peak limit if they were to use the same
thermal interface material right okay so this translates to essentially a very high heat transfer
coefficient for our device right yeah about 300,000 that's the heat transfer coefficient right
so what we're saying is that you can support massive hot spots up to 400 watt per centimeter square
or if you were to even actually use liquid metal instead of the ptm you can actually go to 600
that's right so i guess my question is how though how so essentially we have this there's a there's
a tv screen out there yeah which actually shows oh should we walk into the tv screen yeah showing
the flow demonstration okay um yeah no no no there's a there's a picture on the other side
actually on the tv tv there's a video of mine yeah yeah yeah yeah try to show it yeah okay
all right have you have you felt there's a slight
essentially exactly now so this is an example of how the unit cell structure looks like inside
so it's going to go and zoom in right now
so it uses the short loop unit cells where the flow actually travels a very short distance
it looks like this inside oh essentially the flow comes in vertically and then reverses out
from the spaces between so that's how the internal architecture looks like so the fluid is only
traveling a few millimeters down and see and then back up oh interesting so it's not jet
impingement there are some companies that head jets yeah instead we're traveling through a cylinder
right essentially so that probably helps with like the pressure loss then it yeah you get very low
pressure loss and you're actually forcing fluid through a very small cylinder right and then you're
hitting micro channels underneath the cylinder right and then you're reversing back out cool okay
that's that's the difference they're all parallel it's not a serial system you know all these channels
are in path each hexagon is like a pattern right yeah cooling cooling engine if i were to call it that
for the traditional skype design it's a long loop so from inlay to outlay 30 40 or 50 millimeters
of right for this is smaller than one millimeter right okay few millimeters of travel and you guys
are making this with what like we're making it no it's not pretty printed so let me show you some
it's built on the same as the same manufacturing so you can actually feel this this is the
NVIDIA ruben cold plate it's very light yeah it's just compared with the traditional skype fin cold
plate yep so in this case the skype fin cold plate base as you might imagine is essentially skype machine
now this one the base which is essentially this section is made using the same technology as
agit that's made on metal wafers that are not copper this this is made on copper wafers so it's
basically large semiconductor style wafers which are etched very much like the agit cool and and
then bonded essentially monolithically so there's no interface it feels as though it was 3d printed
but it's not it's actually built on a semiconductor process it's like a deposition rather than but
it's actually etching right okay it's deep etching you know you etch you etch copper so no deposition
there's no deposition only etching it's a tractor it is like machining but it's done in a
semiconductor process sounds expensive no really cheap really yeah really cheap
i mean it's the same technology we use for our etchets well those are very high not that cheap
yeah yeah so when can i have one for my consumer GPU so with consumer gpus the main advantage is that
the cooling is so efficient that you don't need fans the fans can basically be running practically
off or like in this case this is the cdu for but let's come here so i'm actually pulling out 1500
watts yeah and this cdu the fan is basically running at one person duty cycle you can even
turn it off and then it will still pull out 1500 watts and the temperature would be very low
because that's how good the cooling is so you don't need the fans on that's what it would translate
i mean if you have a you know eight fan radiator yeah but most gaming systems won't they'll have
like a dual 120 radiator like you can you can you can kind of push the fan down to the lowest speed
because right you know the better your cooling solution the hotter the fluid that can come in
no i get it you already got me with the sales pitch i just want to know when i can buy it
we are going to start volume production in in june of this year right for like data center
but what about consumer we have not exploded but we will explore okay now we get the answer
the answer is no we can we can i mean i see no reason why it couldn't be yeah i mean that we
were talking to some folks over here don't take the neighbors they came they came over and they're
like can you can you can you get it to the gaming market you know it's that's great yeah i really
like it yeah no i'm i'm sure they do so i mean realistically it'd probably be more like something
you'd want to go to the eliams with though like go straight to like an MSI or see those sorts of
folks yeah very cool all right cool that was it i was just wondering what you guys were up to
but do you want to quickly see the end we get over uh we have like we have like eight minutes
yeah yeah we gotta go all right take care guys have a good rest of your show sorry i'm gonna yeah
yeah thank you so much welcome to the friends designs oh they are awesome now i happen to absolutely
yeah they're so awesome that's the x2 elite that's 25 watts a stand dvp wow one fifth the size
yeah i'm kidding three three yeah three inlets back there is the cost down for the new gen
air tip or is it still expensive i mean it's pretty impressive okay so this is a reference
design this will never be a real product correct it's it's what comes with this design that's cool
though they also made a six millimeters twin right yeah okay that sustains 18 watts dvp
this is comparing to a max surface pro right 30 reduction in thickness but the max doesn't
end as much though so they're my you've loved them i'm not my what sorry i think i know you
don't want to like apple rocks do i i mean i i i like i like products that don't break when i touch
them that's i these are just reference designs they're not intended to be real products um which
is why i tend to not give them too much attention that's that's a different form factor that's
actually running okay we gotta go we gotta go all right yeah yeah sorry
