[Technical Column] Issue 15: Cooling Mechanism of Inverters

As the power of electric vehicles increases, the heat dissipation of the inverter also increases, requiring a high-performance cooling system!

In this column, I will discuss the cooling mechanisms of inverters. The cooling mechanisms of inverters include single-sided cooling, as shown on the left of the diagram, and double-sided cooling, as shown on the right. In the case of single-sided cooling, the semiconductor device is soldered to a substrate and then joined to a heat sink made of ceramic materials with good thermal conductivity and insulation, such as aluminum nitride, which is then cooled through a cooling channel. In this case, to cool the semiconductor substrate from one side, multiple semiconductor chips are arranged on a flat structure and cooled from one side. *For more detailed information, please refer to the related links.
