Every thermal design starts with a solid aluminium heat sink – and many should end there. But as power density climbs and enclosures shrink, there comes a point where no amount of fin area fixes the problem, because the heat can’t spread fast enough to reach it. That is the job of the heat pipe. This guide explains what heat pipes actually do, when a solid heat sink is still the right answer, and the design and fabrication decisions that determine whether a heat-pipe assembly performs as modelled.

A 15-year technical analysis of how China’s EV traction-inverter power electronics moved from imported silicon IGBTs to domestic SiC leadership – BYD, CRRC Times Electric and StarPower compared with Infineon and Wolfspeed.
