Abstract
A switch module for an inverter includes a high-side switch and a low-side switch, each of which has at least one semiconductor switch, wherein the semiconductor switches are attached to a flat substrate; a DC input connection with a positive DC input contact and a negative DC input contact; an AC output connection for outputting an AC phase current of a multi-phase AC output, which is generated by activating the high-side switch and low-side switch on the basis of the DC input; a micro-heat sink that has a coolant intake, a coolant outlet, and a connecting cooling channel structure between the coolant intake and the coolant outlet; wherein the micro-heat sink is designed such that numerous micro-heat sinks, each of which are dedicated to one of numerous switch modules in the inverter, can be releasably connected to one another for fluid exchange at their respective coolant intake and/or coolant outlet.
