Where CoolIT sits in the stack
CoolIT's placements in this catalog cover 4 parts, all in layer 5, liquid cooling (it-side: chip to cdu). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Direct-to-chip cold plates — A metal plate with internal microchannels, bonded or clamped directly onto a GPU, CPU, or switch package, that carries coolant across the die to remove heat by conduction rather than airflow.
- Rack manifolds — The manifold (sometimes called a CDM) that distributes coolant from the CDU supply line to each cold plate in a rack and collects the return flow, usually mounted vertically at the rear or side of the rack.
- Coolant distribution units — The unit that separates the IT-side (technology) coolant loop from the facility water loop, exchanging heat between them and pumping and filtering the technology-side flow — sized from in-rack and in-row units up to multi-megawatt facility-class units.
- Rack/row cooling controls & software — Software and controllers that manage coolant setpoints, pump speed, and valve positions at the rack and row level, and that tie into facility-wide data center infrastructure management (DCIM) systems.

- Is CoolIT publicly traded?
- No listing is on file for CoolIT in this catalog; it is recorded as private.
- Who else makes direct-to-chip cold plates for AI data centers?
- AVC, Auras, Delta Electronics, Flex, Fositek and Foxconn (Hon Hai) are also placed on Direct-to-chip cold plates in this catalog.
- How well sourced are these placements?
- Every part→company placement carries a confidence tag. For CoolIT the mix is 2 disclosed and 2 inferred. "disclosed" means the company or a filing says so; "reported" comes from trade press or a reference-design list; "inferred" is a lead from the taxonomy with no citation yet. Treat reported and inferred as leads, not facts.
