Heatsink of CCB0021M12FM3 for thermal simulation

JeremyZhang

Hi Wolfspeed team,

Our customers are designing the water-cooling system for CCB0021M12FM3, now they need the water-cooling Heatsink information for CCB0021M12FM3 for thermal simulation. They need to know the Thermal conductivity ，density, specific heat capacity, thickness and the material of the Heatsink.

They also need to know the area where a single die is in contact with Heatsink. Thank you so much for your help.

Best Regards,

Jeremy Zhang

Hello Jeremy,

When we do testing on our WolfPACK modules to characterize the thermal resistance, we typically use an Aavid 416601U00000G COTS coldplate with additional machining for mounting and measurements. A datasheet from this coldplate may be found online. A shorter coldplate could likely be utilized.

We utilize 2x modules on this coldplate with large spacings due to fixturing needs. Due to requirements of embedding NTCs and mounting strategies, we typically mount the module on the backside of the coldplate, NOT the side with copper tubing. Mounting on the same side as the flat copper tubing surface may yield higher performance.

Unfortunately, we only share thermal models under NDA. If an NDA exists, we can share via email.

You may find more information about the thermal resistance testing of WolfPACK modules here:
