Where Nidec sits in the stack
Nidec's placements in this catalog cover 4 parts, from layer 4 (servers, racks & integration) to layer 6 (facility cooling & hvac). 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
- Fans — The axial and centrifugal fans mounted in server chassis and rack trays that move air across heatsinks and boards, still needed even in racks that use liquid cooling for the highest-power chips.
- 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.
- 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.
- Fans and motors — Fans and their drive motors that move air through dry coolers, adiabatic units, and cooling towers to reject heat to the atmosphere.
