2. Introduction to GPU Cooling Systems_ "4, AI-related hardware"

Updated: Oct 16, 2024


The reason why liquid cooling becomes the technical direction



"At this stage, air cooling solutions and liquid cooling solutions coexist in intelligent computing"

However, due to the differences in technical design, heat dissipation medium and space between air-cooled servers and liquid-cooled cabinets, there will be certain incompatibilities in the future, and "liquid cooling has become the technical direction"




Air-cooled servers and liquid-cooled cabinets differ in technical design, heat dissipation media, and space, so there are certain incompatibilities:



Differences in heat dissipation methods:


Air-cooled servers use fans to dissipate heat into the surrounding environment.

Liquid-cooled cabinets use a liquid cooling system to absorb and dissipate the heat generated by the server.



Differences in space design:


Air-cooled servers usually have a heat dissipation design that adapts to natural convection or forced convection.

Liquid cooling cabinets, on the other hand, need to be in close contact with the server to transfer heat effectively.



Different manufacturers use different liquid cooling technologies and interface standards:


The development and application of liquid cooling technology varies among different manufacturers.

For example, heat dissipation medium, coolant, pipe connections, etc.

These differences will result in liquid-cooled servers and cabinets from different manufacturers not being compatible with each other.

Liquid Cooling VS Air Cooling

  • Take away heat 3000 times

  • Power consumption 25 times

  • Thermal conductivity 30%



The temperature rise of 1KW equipment and control equipment is 10 degrees, then the air needs 325m^3/h and the cooling water needs 90L/h


  • The heat dissipation medium flow rate differs by 3500 times

  • The power consumption of the device driving the medium flow is 7.3 times different

  • The pipeline space ratio is 20 times different


Yingweida:

Starting with B100, the cooling technology of all future products will be changed from air cooling to liquid cooling. The GB200 released at the GTC conference adopts liquid cooling design.


Huawei:

The Ascend series is basically based on liquid cooling technology.
