Abstract
A power electronics system has a switching device and a liquid cooling device. A switching device has a plate element, and power semiconductor devices are arranged on conductor tracks and connected by means of a connecting device, wherein the liquid cooling device has a first partial body having an inlet volume region and an outlet volume region and a second partial body. A cooling volume region is formed between the two partial bodies, wherein heat transfer bodies protrude into the cooling volume region from the second partial body. The second partial body is arranged in a recess of the first partial body and the two partial bodies are connected to each other and have a common plane surface which forms a first main surface.
