Abstract

A power electronics unit may include a circuit board and a cooling device. The circuit board may include at least one electronic component which, in a heat transfer region, is disposed flat against an electronics side of the circuit board. The cooling device may include at least one impingement jet chamber through which a cooling fluid is flowable from an inlet to an outlet. The cooling device may further include at least one nozzle plate having at least one flow nozzle. The at least one nozzle plate may be arranged in and divide the at least one impingement jet chamber into an inlet chamber and an outlet chamber, which may be fluidically connected to one another via the at least one flow nozzle. The at least one flow nozzle may accelerate and conduct the cooling fluid towards the heat transfer region of the at least one electronic component.
