Custom Copper Liquid Cold Plate for Nvidia Rtx PRO 6000 GPU Ai Workstation

The card geometry is what we work from: die position and footprint, mounting hole pattern, keep-out zones and board thickness, plus the port position and hose routing your chassis allows. A drawing or 3D model in STEP / IGES / DWG / PDF is the fastest route. If the layout is still open, we can start from heat load per card, coolant type and inlet temperature, and the pressure drop your loop can allow. DFM review is completed before quotation.

Coldwerk delivers at cold plate and component level. Where a project extends to backplate, bracket, hose routing or quick disconnects, project coordination is available and the delivery content is defined per project. Card-level assembly and final electrical validation stay with you as the integrator.

The usual reason is slot density rather than raw heat removal. A multi-slot air cooler occupies neighbouring slots and pushes hot air into the chassis; a cold plate takes the heat out through the loop and frees those slots, so more cards fit in the same enclosure. Noise and inlet-air recirculation are the secondary reasons customers give us.

The closing process is selected per design. In-house processes include CNC machining, skived fin, extruded profile, embedded tube and brazing. Where a design calls for microchannel geometry, friction stir welding or vacuum brazing, these are available for your project and executed at qualified partner facilities within our Dongguan manufacturing base, with Coldwerk retaining engineering review, process selection, inspection and single-point accountability.

Nitrogen leak and pressure testing and CMM dimensional inspection are carried out in-house. Helium leak testing is available for your project at qualified partner facilities within our Dongguan manufacturing base. Test pressure, hold time and acceptance criteria are set by your drawing or the project test plan rather than by a catalogue figure. Leak testing is performed on the cold plate before it reaches your assembly line, never on a populated card.
