A copper microchannel cold plate lands on a glowing accelerator die

Direct-to-chip liquid cooling

We take the heatoff the die.

Copper microchannel cold plates, rack manifolds and CDUs for 1.6 kW-class accelerators. Engineered, qualified and supported as one loop.

  • 1600W Heat removed per cold plate
  • 0.021°C/W Thermal resistance, die to fluid
  • 33kPa Pressure drop at 1.5 L/min

01The handoff

Air stops workingat 700 watts.

A 1.6 kW accelerator cannot reject its heat into moving air; the film of air against the lid becomes the whole thermal budget. A cold plate replaces that film with a copper wall 0.4 mm from the die and a fluid that carries 3,500 times more heat per unit volume.

Everything downstream — manifold, quick disconnect, CDU, facility water — exists to keep that wall cold and the pressure honest.

02One loop, five handovers

    0.021 °C/W

    Copper microchannels sit 0.4 mm from the die. Flow enters at 25 °C and leaves at 33 °C.

    Quick disconnect

    < 0.1 mL spill

    Dry-break couplings let a sled be pulled under load without draining the rack.

    8–48 ports

    Vertical bar balances flow across sleds so the last node is not the hot one.

    CDU

    132 kW

    Liquid-to-liquid heat exchange, redundant pumps, and the control loop that holds supply temperature.

    W3 / W4

    Warm-water operation lets dry coolers do the work for most of the year.

03Hardware

Built to bespecified, not browsed.

Every line ships with a thermal datasheet, a pressure-drop curve and a CAD model. Pricing is quoted per deployment.

05How a deployment runs

From thermal model to signed-off rack

  1. 01

    Thermal review

    We model your package, flow budget and facility water before quoting anything.

  2. 02

    Qualification

    Cold plates run on a thermal test vehicle; you get the curve, not a claim.

  3. 03

    Integration

    Manifolds, hoses and CDU sized to the rack, with leak-path review and commissioning plan.

  4. 04

    Operation

    Fluid chemistry programme, spares, and a service window that matches your maintenance policy.

06Where it runs

Density isa thermal decision.

  • 120 kW/rack

    AI training halls

    Eight-way accelerator sleds at full utilisation, twenty-four hours a day.

  • 40 °C water

    HPC and research

    Warm-water loops that reject heat without mechanical cooling most of the year.

  • 0 raised floor

    Colocation retrofit

    Sidecar CDUs that take a liquid-cooled row into an air-cooled building.
