FAQ

Which listed companies are liquid cooling stocks plays?

Based on each company's own annual report disclosures, this map currently places 14 Taiwan-listed companies: KAIMEI（2375）、SUNON（2421）、I-CHIUN（2486）、AVC（3017）、ADDA（3071）、ABC（3236）、AURAS（3324）、TAISOL（3338）、FCN（3483）、JENTECH（3653）、Lemtech-KY（4912）、NCCI（6230）、Y.S.TECH（6275）、MICROLOOPS（6831）. A company's position is determined by the products its annual report says it makes — with the original excerpt cited.

Which Taiwan companies make data center liquid cooling?

The Liquid Cooling Systems node lists every Taiwan-listed company whose annual report discloses liquid-cooling products (cold plates, CDUs, manifolds, in-rack systems) — click it for each company and excerpt. Air-cooling thermal modules sit on a parallel node, so you can see which companies straddle the air-to-liquid transition.

Where does the data on this map come from?

Two sources, styled differently on the map: relations tagged with a stock code are extracted from that company's annual report (click an edge to see the original Chinese excerpt and page); the backbone chain is an editorial framework that keeps the chain connected end-to-end. Company placements come 100% from disclosures — nothing is inferred.

Why do some items show no companies?

Dashed items have no collected annual-report disclosure yet — the segment may be dominated by non-Taiwan or unlisted players, or simply not yet covered. We deliberately distinguish "no companies" from "not yet covered".

Compiled from public annual-report disclosures for research and educational reference only — not investment advice or stock recommendations. The backbone chain is an editorial framework; company placements and code-tagged relations cite annual-report originals (in Chinese). Disclosures reflect their reporting period (FY2024 annual report, FY2025 annual report) and not current operations.
