Alfa Laval AB — AI supply-chain exposure

Alfa Laval makes plate heat exchangers, a core component of the liquid-cooling and heat-reuse loops that increasingly sit inside data centers. As accelerators run hotter, air cooling gives way to liquid, and the heat exchanger is the interface that passes heat from the chip loop to the facility's water or district-heating system.

Its structural hook is that liquid cooling is shifting from optional to mandatory as rack power densities climb, and heat exchangers are a mature, precision product with a short list of credible suppliers. That makes Alfa Laval a direct beneficiary of the thermal problem the whole industry now faces. It is a component supplier rather than a system integrator, so its centrality is modest, but it is levered to one of the fastest-tightening parts of the physical stack.
