WEBVTT

00:00:00.000 --> 00:00:03.760
yeah so this is an example of what makes it special yeah so here we are actually

00:00:03.760 --> 00:00:10.160
pooling a very large hot spot so this is a single radical dart 25 by 32 millimeters

00:00:10.800 --> 00:00:16.720
and we have basically heated up one ninth of this essentially at 10 millimeter by 10 millimeter

00:00:16.720 --> 00:00:22.560
rectangle yeah with 402 watt per centimeter square which is an extremely high number yeah

00:00:23.360 --> 00:00:28.880
and we're using phase change 10 which is about point of six and we're showing that we can maintain

00:00:28.960 --> 00:00:36.560
junction temperatures of about 94 degrees and the thermal resistance of our device of

00:00:36.560 --> 00:00:42.560
just our liquid jet is about point of five now comparable solutions in the market today

00:00:42.560 --> 00:00:47.920
they can get about 300 watt per centimeter that's the peak limit if they were to use the same

00:00:47.920 --> 00:00:52.560
thermal interface material right okay so this translates to essentially a very high heat transfer

00:00:52.560 --> 00:00:57.120
coefficient for our device right yeah about 300,000 that's the heat transfer coefficient right

00:00:57.760 --> 00:01:04.560
so what we're saying is that you can support massive hot spots up to 400 watt per centimeter square

00:01:04.560 --> 00:01:10.080
or if you were to even actually use liquid metal instead of the ptm you can actually go to 600

00:01:10.080 --> 00:01:17.600
that's right so i guess my question is how though how so essentially we have this there's a there's

00:01:17.600 --> 00:01:23.040
a tv screen out there yeah which actually shows oh should we walk into the tv screen yeah showing

00:01:23.040 --> 00:01:31.440
the flow demonstration okay um yeah no no no there's a there's a picture on the other side

00:01:31.440 --> 00:01:38.960
actually on the tv tv there's a video of mine yeah yeah yeah yeah try to show it yeah okay

00:01:38.960 --> 00:01:40.960
all right have you have you felt there's a slight

00:01:53.120 --> 00:02:00.080
essentially exactly now so this is an example of how the unit cell structure looks like inside

00:02:01.040 --> 00:02:03.600
so it's going to go and zoom in right now

00:02:06.240 --> 00:02:12.240
so it uses the short loop unit cells where the flow actually travels a very short distance

00:02:12.240 --> 00:02:17.920
it looks like this inside oh essentially the flow comes in vertically and then reverses out

00:02:17.920 --> 00:02:22.880
from the spaces between so that's how the internal architecture looks like so the fluid is only

00:02:22.880 --> 00:02:29.360
traveling a few millimeters down and see and then back up oh interesting so it's not jet

00:02:29.360 --> 00:02:34.080
impingement there are some companies that head jets yeah instead we're traveling through a cylinder

00:02:34.080 --> 00:02:38.640
right essentially so that probably helps with like the pressure loss then it yeah you get very low

00:02:38.640 --> 00:02:43.760
pressure loss and you're actually forcing fluid through a very small cylinder right and then you're

00:02:43.760 --> 00:02:48.880
hitting micro channels underneath the cylinder right and then you're reversing back out cool okay

00:02:48.880 --> 00:02:55.360
that's that's the difference they're all parallel it's not a serial system you know all these channels

00:02:55.360 --> 00:03:00.800
are in path each hexagon is like a pattern right yeah cooling cooling engine if i were to call it that

00:03:00.800 --> 00:03:07.920
for the traditional skype design it's a long loop so from inlay to outlay 30 40 or 50 millimeters

00:03:07.920 --> 00:03:13.680
of right for this is smaller than one millimeter right okay few millimeters of travel and you guys

00:03:13.680 --> 00:03:19.440
are making this with what like we're making it no it's not pretty printed so let me show you some

00:03:20.720 --> 00:03:29.520
it's built on the same as the same manufacturing so you can actually feel this this is the

00:03:29.520 --> 00:03:35.680
NVIDIA ruben cold plate it's very light yeah it's just compared with the traditional skype fin cold

00:03:35.680 --> 00:03:43.360
plate yep so in this case the skype fin cold plate base as you might imagine is essentially skype machine

00:03:44.320 --> 00:03:50.080
now this one the base which is essentially this section is made using the same technology as

00:03:50.080 --> 00:03:55.840
agit that's made on metal wafers that are not copper this this is made on copper wafers so it's

00:03:55.840 --> 00:04:02.080
basically large semiconductor style wafers which are etched very much like the agit cool and and

00:04:02.080 --> 00:04:07.920
then bonded essentially monolithically so there's no interface it feels as though it was 3d printed

00:04:07.920 --> 00:04:12.960
but it's not it's actually built on a semiconductor process it's like a deposition rather than but

00:04:13.120 --> 00:04:20.240
it's actually etching right okay it's deep etching you know you etch you etch copper so no deposition

00:04:20.240 --> 00:04:25.280
there's no deposition only etching it's a tractor it is like machining but it's done in a

00:04:25.280 --> 00:04:31.440
semiconductor process sounds expensive no really cheap really yeah really cheap

00:04:32.560 --> 00:04:37.280
i mean it's the same technology we use for our etchets well those are very high not that cheap

00:04:37.280 --> 00:04:44.080
yeah yeah so when can i have one for my consumer GPU so with consumer gpus the main advantage is that

00:04:44.080 --> 00:04:50.160
the cooling is so efficient that you don't need fans the fans can basically be running practically

00:04:50.160 --> 00:04:58.400
off or like in this case this is the cdu for but let's come here so i'm actually pulling out 1500

00:04:58.400 --> 00:05:05.200
watts yeah and this cdu the fan is basically running at one person duty cycle you can even

00:05:05.200 --> 00:05:10.160
turn it off and then it will still pull out 1500 watts and the temperature would be very low

00:05:10.160 --> 00:05:14.720
because that's how good the cooling is so you don't need the fans on that's what it would translate

00:05:14.720 --> 00:05:20.560
i mean if you have a you know eight fan radiator yeah but most gaming systems won't they'll have

00:05:20.560 --> 00:05:26.720
like a dual 120 radiator like you can you can you can kind of push the fan down to the lowest speed

00:05:27.440 --> 00:05:33.120
because right you know the better your cooling solution the hotter the fluid that can come in

00:05:33.120 --> 00:05:36.720
no i get it you already got me with the sales pitch i just want to know when i can buy it

00:05:38.160 --> 00:05:44.960
we are going to start volume production in in june of this year right for like data center

00:05:44.960 --> 00:05:50.240
but what about consumer we have not exploded but we will explore okay now we get the answer

00:05:51.200 --> 00:06:00.320
the answer is no we can we can i mean i see no reason why it couldn't be yeah i mean that we

00:06:00.320 --> 00:06:06.160
were talking to some folks over here don't take the neighbors they came they came over and they're

00:06:06.160 --> 00:06:10.720
like can you can you can you get it to the gaming market you know it's that's great yeah i really

00:06:10.720 --> 00:06:16.080
like it yeah no i'm i'm sure they do so i mean realistically it'd probably be more like something

00:06:16.080 --> 00:06:21.840
you'd want to go to the eliams with though like go straight to like an MSI or see those sorts of

00:06:21.840 --> 00:06:26.640
folks yeah very cool all right cool that was it i was just wondering what you guys were up to

00:06:26.640 --> 00:06:31.280
but do you want to quickly see the end we get over uh we have like we have like eight minutes

00:06:31.280 --> 00:06:35.600
yeah yeah we gotta go all right take care guys have a good rest of your show sorry i'm gonna yeah

00:06:35.600 --> 00:06:42.640
yeah thank you so much welcome to the friends designs oh they are awesome now i happen to absolutely

00:06:42.640 --> 00:06:54.640
yeah they're so awesome that's the x2 elite that's 25 watts a stand dvp wow one fifth the size

00:06:54.640 --> 00:07:10.640
yeah i'm kidding three three yeah three inlets back there is the cost down for the new gen

00:07:10.640 --> 00:07:18.640
air tip or is it still expensive i mean it's pretty impressive okay so this is a reference

00:07:18.640 --> 00:07:22.960
design this will never be a real product correct it's it's what comes with this design that's cool

00:07:22.960 --> 00:07:31.360
though they also made a six millimeters twin right yeah okay that sustains 18 watts dvp

00:07:32.400 --> 00:07:38.000
this is comparing to a max surface pro right 30 reduction in thickness but the max doesn't

00:07:38.000 --> 00:07:46.080
end as much though so they're my you've loved them i'm not my what sorry i think i know you

00:07:46.080 --> 00:07:53.440
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

00:07:53.440 --> 00:07:59.440
them that's i these are just reference designs they're not intended to be real products um which

00:07:59.440 --> 00:08:04.480
is why i tend to not give them too much attention that's that's a different form factor that's

00:08:04.480 --> 00:08:09.200
actually running okay we gotta go we gotta go all right yeah yeah sorry
