How to : Optimize an IGBT Cold Plate

Insulated Gate Bipolar Transistor (IGBT) modules, are used in a wide range of industries. In electronics, IGBTs are used for Variable-Frequency Drives (VFD), for electric vehicle induction furnaces, in wind power applications and also in refrigerators, to give just a few examples.
An increase of the cooling fluid velocity increases the heat transfer coefficient. This leads to a higher heat flow rate, which leads to lower IGBT chip temperatures. However, at the same time, higher velocities also cause an increased pressure drop. The heat exchanging surface area, in this case, the cold plate surface, can be modified by pins or fins in several variants and arrangements.
