Rear-Door Heat Exchangers
Technology
Cooling
Liquid-cooled doors that upgrade air racks without touching servers.
You're looking at a technology record: a building block of AI hardware — what it does, who makes it, and which chips and systems use it.
A rear-door heat exchanger replaces a rack's back door with a water coil, capturing 30–80 kW of exhaust heat at the rack. It is the retrofit bridge for H100/H200-class gear in halls that cannot yet plumb cold plates.
