CP 4012D

4000 series cold plate for the Wolfspeed XM3 module

The CP4012D aluminum friction stir welded cold plate has been optimized specifically for the high heat flux of silicon carbide. The MDT (micro deformation technology) inside allows for very low thermal resistance, low-pressure drop, and balanced parallel flow.

* Thermal resistance is calculated as the difference between maximum cold plate temp and the inlet fluid temp divided by the total cold plate power.
** Pressure drop is calculated from inlet to outlet without fittings, Coolant used for testing: 50/50 water and ethylene glycol.
***Preliminary results based off www.microcooltool.com, see below for empirical results

See empirical testing results below from Wolfspeed:
Using a 50/50 water-ethylene-glycol coolant with a flowrate of 12 L/min and a temperature of 25°C, the maximum power dissipation for the flat baseplate CAB450M12XM3 is measured at 750 W per position at a junction temperature of 175°C for a thermal resistance of 0.2°C/W for RΘJL (junction to liquid)

MDT In Line Pin Fin Options:

  • 4 fin/inch (~2.4mm gaps) Best pressure drop
  • 8 fin/inch (~1.2mm gaps)
  • 12 fin/inch (~1mm gaps)
  • 20 fin/inch (~0.5mm gaps) Highest performance
