Key Players
Competitive Landscape
Competition in localized hotspot cooling centers on how much of the thermal path a supplier can own from processor heat capture through rack distribution and downstream heat rejection. Buyers compare component compatibility and commissioning support because a high-capacity cold plate has limited value if the CDU, manifold or facility loop becomes the constraint.
Recent investment is moving toward manufacturing capacity and broader system ownership. nVent is expanding liquid-cooling production, Vertiv is extending high-capacity CDU and manifold coverage, Eaton has added Boyd Thermal, and JetCool is pairing processor cooling with rack-level coolant distribution through Flex-backed deployment support. Commercial selection turns on repeatable engineering and clear service responsibility at the target rack density.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| nVent announced a 160,000-square-foot Minnesota liquid-cooling manufacturing site in July 2026 | AI and HPC deployments require repeatable liquid-cooling hardware at higher volume | Suppliers add dedicated production capacity for data center liquid cooling | Longer-run supply agreements for rack and row cooling programs |
| Vertiv expanded EMEA liquid cooling with CoolChip CDU 2300 and row manifolds in May 2026 | Operators need higher-capacity coolant distribution for dense AI blocks | CDUs and manifolds are packaged inside wider thermal chains | Standardized high-density deployments across new and retrofit sites |
| Eaton completed its acquisition of Boyd Thermal in March 2026 | Customers want power and cooling infrastructure planned together | Power-management suppliers are adding liquid-cooling capability | Grid-to-chip engineering and bundled infrastructure programs |
JetCool, nVent, Vertiv and Boyd Thermal by Eaton cover different sections of the localized thermal chain, from processor heat capture and rack distribution to facility-loop integration. Their competitive positions depend on documented operating limits and deployment support rather than corporate scale.

The competitive set reflects official product information and announced deployments relevant to direct liquid cooling and supporting thermal infrastructure.
Which companies focus on processor-level heat capture?
JetCool and nVent both provide direct-to-chip cooling capabilities with rack-level coolant distribution. JetCool emphasizes its SmartPlate and SmartSense combination, while nVent combines liquid-cooling hardware with broader rack and row infrastructure.
Which company extends farther into facility heat rejection?
Vertiv connects direct liquid cooling with coolant distribution, row manifolds and downstream heat-rejection equipment. This wider thermal-chain approach suits projects where operators want fewer interfaces between rack cooling and facility mechanical systems.
How does Boyd Thermal by Eaton compete?
Boyd Thermal by Eaton combines cold plates, liquid loops and coolant distribution with broader thermal engineering. Eaton ownership adds power-management reach, creating a route for customers that want cooling coordinated with electrical infrastructure.
What differentiates deployment support?
Deployment support depends on whether the supplier can validate interfaces before rack delivery and remain accountable through commissioning. Manufacturing capacity and regional service coverage matter when operators need the same thermal architecture repeated across several AI halls or sites.
Representative Company Overview
| Company | Positioning | Verified market-relevant capabilities |
|---|---|---|
| JetCool | Direct-to-chip and rack-level cooling | SmartPlate cold plates and SmartSense CDU support processor-level heat capture with rack or row coolant distribution. |
| nVent | Rack and row liquid-cooling infrastructure | Liquid-cooling portfolio includes CDUs plus rack and row distribution, supported by expanding manufacturing capacity for AI and HPC demand. |
| Vertiv | Integrated data center thermal infrastructure | CoolChip CDUs and fluid-network manifolds connect direct-to-chip or rear-door cooling with controls and downstream thermal infrastructure. |
| Boyd Thermal by Eaton | Engineered thermal systems within a wider power portfolio | Cold plates, loops and CDUs support liquid-cooled data center systems, now combined with Eaton power-management infrastructure. |
Research Methodology
The companies shown here illustrate how competition is structured rather than ranking corporate scale or revenue. Inclusion requires official evidence of processor-level cooling, coolant distribution, heat-rejection integration or deployment capability relevant to AI data centers. Government sources establish country infrastructure conditions, while company newsrooms and product documentation establish current capabilities and announced capacity. Segment shares and country CAGRs are FMI estimates for the 2026 to 2036 assessment period.
