Claim Text:
1. A power electronics module, comprising: a first power electronics element that generates a first heat flow during operation of the power electronics module; a second power electronics element that contributes to the generation of a second heat flow during operation of the power electronics module; and a secondary cooling circuit having a first cooler, wherein the first cooler is in thermal contact with the first power electronics element to receive at least part of the first heat flow, wherein the second cooler is in thermal contact with the second power electronics element to receive at least part of the second heat flow, wherein the heat exchanger is configured to transfer at least part of the first heat flow and the second heat flow to a primary cooling flow during the operation of the power electronics module, and wherein the heat exchanger is configured to be thermally efficient for transferring a heat flow such that the magnitude of said heat flow is less than a total magnitude that is formed from a maximum first heat flow and a maximum second heat flow.
