Delta Power and Liquid Cooling Solutions for NVIDIA AI Data Centers
Delta Electronics is one of NVIDIA’s most important global core suppliers for power and liquid cooling thermal management, acting not only as a component provider but also as a strategic R&D partner for the tech giant’s next-generation AI data center architecture.
As the global leader in AI server power supplies, Delta holds the top market share in AI server power supply units. It collaborates deeply with NVIDIA to develop the 800V High-Voltage Direct Current (HVDC) power architecture, a next-generation industry standard designed specifically for NVIDIA’s Blackwell and subsequent Rubin platform AI architectures, effectively addressing power consumption and space constraints in large-scale AI computing clusters. For NVIDIA’s GB200 and GB300 systems, Delta delivers a full suite of power conversion solutions, from AC/DC power shelves to DC/DC converters, with efficiency reaching up to 98%.
With single-chip power consumption exceeding kilowatt levels, Delta’s position in thermal management has grown rapidly. As NVIDIA moves to fully adopt 100% liquid cooling systems (such as the Vera Rubin platform) by 2026, Delta has evolved from a single-component supplier to a provider of complete liquid cooling solutions. Its offerings include liquid-to-liquid coolant distribution units (CDUs), cold plates, manifolds, liquid cooling connectors, and high-efficiency cooling fans, supporting dielectric liquid cooling fluid for reliable heat transfer. These liquid cooling technologies are critical to ensuring stable GPU operation for Blackwell platform systems like NVL72 rack-level configurations, positioning Delta alongside leading thermal management providers.
At the heart of Delta’s liquid cooling portfolio is the HEC Cold Plate Liquid Cooling Rack System, composed of cabinets, CDUs, Power Shelves, manifolds, bus bars, and more. Designed for high-computing-density scenarios including supercomputing centers, intelligent computing centers, and edge computing, this low PUE data center solution delivers exceptional performance with a data center cooling PUE below 1.1, representing a breakthrough in optimizing data center liquid cooling PUE. For those wondering how much energy does liquid cooling save, Delta’s energy saving liquid cooling system delivers tangible results, boosting efficiency by 5% compared to traditional UPS systems through DC48V Power Shelves paired with lithium batteries, eliminating air conditioning needs with a 100% liquid cooling design combining 80% cold plate cooling and 20% evaporative cooling backplanes. With a maximum rack density of 200kW, the system supports both centralized CDUs (up to 2400kW per rack) and rack-level CDUs (up to 120kW at 4U height), catering to diverse deployment needs.
Beyond thermal efficiency, Delta’s HEC system offers comprehensive intelligent management, with the first rack equipped with a management system to collect real-time parameters of all racks in a row, enabling centralized display and fault prediction. Factory pre-assembled, tested, and delivered as a complete rack, the system ensures zero on-site installation, with full blind-plug design eliminating cables for server cooling and power, streamlining deployment and maintenance. Leveraging extensive experience in liquid cooling system OEM ODM, Delta also provides customized solutions to support overseas data center cooling project deployments worldwide, backed by robust technical expertise and global service capabilities.
