Cooling and Structural Parts for Industrial Control Equipment

Requirement

Industrial control equipment varies widely: a fanless chassis uses the heat sink as its outer surface, a VFD has to deal with high heat flux at the IGBT, and automation equipment needs structure and assembly accuracy at the same time.

Our approach

We split the work into three types: enclosure cooling (contact face first), module cooling (base and fin geometry first), and structural parts (hole position and flatness first). Finish and colour are unified within a project to avoid shade mismatch on the assembled machine.

Enclosure cooling

The heat sink is the rear of the chassis, so contact face flatness drives board temperature. We mill and correct that face separately, and machine clearance slots after skiving.

Module cooling

For IGBT modules the base thickness and flatness matter most; fin geometry follows airflow. Sampling with two fin heights is a useful comparison.

Structural parts

Brackets, panels and connectors are judged on hole position and batch consistency — one fixture, full first-article inspection.
