Abstract: An exemplary power electronics module includes a first power electronics element that generates a first heat flow during operation of the power electronics module, a second power electronics element that generates a second heat flow during operation of the power electronics module. The first cooler is in thermal contact with the first power electronics element to receive at least part of the first heat flow. The second cooler is in thermal contact with the second power electronics element to receive at least part of the second heat flow. A heat exchanger is configured to transmit at least part of the first heat flow and the second heat flow to a primary cooling flow and transfer heat flow in a thermally efficient manner. A magnitude of the heat flow is less than a total magnitude that is formed from a maximum first heat flow and a maximum second heat flow.
