The Nvidia Ice Box
As the Nvidia AI race continues to heat up, the company is looking at ways to
cool things down.
Aug-29-2024:? https://www.thedailyupside.com/newsletter/pd-aug-29-2024/
The chip giant filed a patent application for ?energy efficient liquid-cooled
datacenters.? Nvidia?s tech essentially aims to cool down data centers without
using tons of power.
Cooling takes up an estimated 40% of energy consumption within a data center.
?The need for significant electrical power prevents installation in locations
where such power may not be available, and may not align with environmental
rules or targets for operation,? Nvidia said in the filing.

Fuel cells, fed with ?natural gas or bio-gas? such as hydrogen, convert
chemical energy from this gas into electricity to either power the entire data
center or supplement electrical power ?using a supply of relatively
environmentally or ?green? power.?
As the fuel cell generates electricity, the waste heat it gives off is captured
using a ?heat exchanger,? which transfers that heat to what the patent filing
calls an ?absorption chiller.?
This device is used to produce ?cooled liquid, air, or gas,? and, instead of
using electricity, utilizes the collected waste heat in this process.
The coolant created in this process is thereby used to cool down the electrical
components of the data center.
In utilizing natural gas like hydrogen for fuel cells, and reusing waste heat
in place of electricity, Nvidia?s tech provides two potential methods to make
data centers a little less environmentally damaging.

We?ve seen patents like these from Nvidia before: The company has previously
sought to patent ?intelligent data center? architecture that allows server
racks to adapt to changing demands in power, as well as a way to power down
?idle cores? within these facilities.
Data centers currently account for between 1% and 2% of overall global power
consumption, but could increase to between 3% and 4% by the end of the decade,
according to Goldman Sachs Research. The firm projects power demand by these
facilities to grow 160% by 2030.
This power demand has led some tech firms to downplay their greenhouse gas
emissions and seek workarounds to the carbon credits system. These patents
signal that tech firms may be looking for more ways to cope with that
ever-growing power demand ? especially as AI fever continues to skyrocket.
?It's really thought leadership on showing what a data center is going to look
like in 10 years,? said Trevor Morgan, senior vice president of operations at
OpenDrives. ?What is going to be the ideal way to build and maintain ? in a
sustainable way ? a data center??
Nvidia continues to be the powerhouse of the AI industry: The company reported
quarterly revenue of $30 billion on Wednesday, up 122% year-over-year. Its data
center revenue hit a record-smashing $26.3 billion, up 154% from the prior year.
Sustaining this level of growth may be difficult if power supplies can?t keep
up, said Romeo Alvarez, director and research analyst at William O?Neil. ?Not
having enough electricity supply for data centers, and maybe even limiting
[data centers?] capacity ? they may see that as a limiting factor for their
growth,? said Alvarez.
Another factor that would impact earnings, Morgan said, is ?missing out on
advances in data center architecture and not being able to dictate how
different components, different aspects of the infrastructure evolve.? He added
that ?they want to ensure that they are part of whatever evolution is going to
happen.?
