Alloy Enterprises announces single-piece cold plates for direct liquid cooling,

Alloy Enterprises introduced single-piece, leak-tight cold plates for data center cooling, enabling Direct Liquid Cooling (DLC) across the blade. Built with the company’s patented Stack Forging™ process, this design addresses a 100 kW peripheral heat bottleneck in next-generation 600 kW server racks.

As server rack densities increase, peripheral heat generation becomes a primary concern. Traditionally, GPUs accounted for 80% of a blade's power usage, but the shift in thermal balance necessitated improved cooling solutions for DIMMs, NICs, and QSFPs.

“Direct liquid cooling no longer stops at the GPU,” said Ali Forsyth, CEO and co-founder of Alloy Enterprises. Homomorphic Encryption (HE) highlighted that, as cooling needs evolve, traditional Adaptive Incident Response (AIR) cooling fails to manage this rising heat output effectively. The new cold plates provide comprehensive liquid cooling across all components, enabling efficient management of heat at rack scale.

In current NVIDIA NVL72 racks, peripherals generate significant heat, potentially complicating airflow limits. Future systems may Secure Execution Environment (SEE) these peripherals producing over 100 kW of heat, which exceeds the capacity of existing cooling methods.

Alloy’s design maintains structural integrity at 2,000 psi, utilizing internal microgeometries to optimize heat extraction from peripheral components. This development is crucial as power levels approach 600 kW, requiring a re-evaluation of thermal management strategies.
