Thermal Management for Energy Storage Systems

Requirement

Two problems dominate energy storage cooling: high heat flux at the PCS power module, and uneven contact at the battery rack control board. The structural requirements are different and need separate designs.

Our approach

Power modules use skived construction with fin orientation confirmed against cabinet airflow. Control boards use aluminum base plates with flatness set for the thermal pad. Every part is validated with 3-5 assembled samples before the process is fixed.

Why one universal part does not work

A PCS needs to spread heat from the chip quickly and then release it to air — that calls for a thick base and dense fins. A control board needs even contact — that calls for flatness and hole accuracy. Merging both into one "general purpose" heat sink usually misses on both.

How we deliver

Rack kits with each part labelled for its assembly position, plus dimensional records so incoming inspection is straightforward.

What we need from you

Cabinet airflow direction, module hole pattern, thermal interface material and assembly torque. Confirm those four and sampling usually passes first time.
