Where Wiwynn sits in the stack
Wiwynn's placements in this catalog cover 3 parts, from layer 4 (servers, racks & integration) to 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
- Rack-scale systems — A rack-scale system is the fully integrated cabinet of compute trays, switch trays, power shelves, cooling manifolds and busbar that ships as one wired unit rather than as discrete servers.
- GPU baseboards & compute trays — The baseboard is the printed circuit assembly that carries the GPUs (and often paired CPUs) and their direct power and interconnect, packaged into a tray that slides into the rack.
- 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.
