How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The size was built upward from unit volumes and realised prices. For each cooling technology, CDI estimated the shipped base of coolant distribution units, cold plates, heat exchangers, pumps, manifolds and immersion tanks, then applied realised selling prices by capacity band and rack power density. Liquid-ready rack deployments at data centers, electric vehicle battery pack output and high-performance computing system shipments supplied the volume side. The build was then checked against disclosed segment revenue from listed thermal management suppliers and customs shipment data for heat exchangers and pumps. Where the two disagreed, the bottom-up assumption on units or price was corrected; the disclosed revenue served only as a check and was never averaged into the estimate.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Interviews target the roles that decide or influence a liquid cooling purchase: data center design and facilities leads, procurement heads at colocation and cloud operators, thermal engineers at server and accelerator makers, battery pack engineers at vehicle manufacturers, and channel partners that integrate cooling into racks. Supplier-side conversations cover sales heads and product managers at coolant distribution, cold plate and immersion tank makers. Sampling emphasises North America and Asia Pacific, where most capacity is being deployed, with a smaller set of conversations in Europe, the Middle East and Latin America to test regional pricing, lead times and retrofit practice.
Desk research rests on filed company reports and investor presentations from thermal management suppliers, harmonised system customs codes for heat exchange units (8419) and pumps (8413), and patent filings for cold plate and immersion designs. Standards and trade-body material includes the ASHRAE thermal guidelines for liquid-cooled data processing environments and the Open Compute Project liquid cooling specifications. Energy and efficiency rules come from the European Energy Efficiency Directive reporting framework and national data center regulations. Vehicle battery cooling inputs draw on automaker technical disclosures and type-approval filings.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from rack deployment plans, accelerator power trends and the share of new capacity specified as liquid-cooled, with prices held close to current levels after volume discounts. Adoption of direct-to-chip cooling follows server platforms that ship liquid-ready, and immersion grows from a small base as standards mature. Electric vehicle and power electronics demand follows battery pack output. For the forecast to hold, accelerator power per chip must keep rising, grid connections must allow high-density sites to open on schedule, and coolant and component supply must keep pace. A pause in compute capital spending would slow the early years most.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Outputs were back-tested against recorded growth for 2020 to 2024 using supplier shipments and company segment revenue, and the historical curve was checked for breaks. Segment shifts, such as the move from rear door and in-row units toward direct-to-chip and immersion, were reviewed with technical and procurement experts. Sensitivities tested a delay in high-density rack deployment, a fall in unit prices from scale and a faster retrofit rate. Regional totals, segment totals and the driver table were reconciled to the headline in every year, and any gap was traced to a volume or price input.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
Confidence is firmest for data center direct-to-chip cooling and coolant distribution units, where supplier disclosures and public deployment programmes give a clear volume and price base. It is thinner for immersion cooling, spray cooling, cryptocurrency mining and medical equipment, where adoption is early and reporting is sparse. The band around the 2025 figure is wide because definitions of liquid cooling vary across buyers. Revisions would follow a change in accelerator power roadmaps, a shift in data center build schedules or new coolant regulation.
