across automotive, aerospace and other high-performance industries. Today, I see many of the same challenges emerging in the design of next-generation data centres.
Cooling technology is evolving alongside processors
Liquid cooling is no longer viewed as a future technology for AI infrastructure. As power densities rise, the industry has recognised that air cooling alone cannot support the next generation of high-performance computing.
Although removing more heat, more efficiently is patently crucial, the challenge goes beyond that with the pace of development and the rapid iteration required to keep up.
Every new generation of GPUs introduces different thermal profiles, power densities and packaging constraints. Cooling systems must therefore evolve alongside the hardware they support.
Cold plates, once considered relatively standard components, are rapidly becoming highly engineered thermal devices designed around specific processors, server architectures and operating conditions. Their performance depends not only on coolant selection or flow rate, but on how effectively internal geometries distribute coolant precisely to where heat is generated.
Like Formula One, AI infrastructure is adopting a cycle of relentless engineering development, where thermal systems are continuously redesigned and optimised to evolve alongside each new generation of technology.
The overlooked cost of pressure drop
When operators assess liquid-cooling performance, the first question is often simple: can the system remove enough heat? While this is an excellent place to start, it is not the only question we should be asking. A more revealing question is how much energy the system must use to deliver that cooling.
That is where pressure drop becomes commercially important. As data-centre scale, marginal hydraulic inefficiencies can compound across thousands of servers, quietly adding pump power, energy use and operating cost.
This is where liquid cooling performance becomes a systems-level issue rather than a component-level specification. A cold plate that achieves excellent heat removal but creates excessive hydraulic resistance may simply shift the energy burden elsewhere in the system. The facility still pays for that inefficiency through higher pump energy, greater infrastructure demand and reduced operational flexibility.
