Abstract: The present disclosure concerns a mounting device for semiconductor packages, and a heat dissipation assembly with such a mounting device. The mounting device includes a bottom side comprising one or more cavities to house semiconductor packages, and a top side comprising a plurality of holes extending from the bottom side to the top side for accommodating contact pins of the semiconductor packages. A fixation mechanism fixes the mounting device to a heat dissipation structure.

Abstract: A heat exchanger for heating a fluid that exhibits simplified manufacturing, a reduced construction size, and/or an increased heating efficiency. The heat exchanger has at least two distanced tube bodies through which a flow path of the fluid leads. A thin-film resistor is applied on the outer surface of at least one of the tube bodies with an interface made of a thermal interface material located between the thick-film resistor and the next neighboring tube body.

Abstract: A method for operating a brushed direct current electric motor may include receiving an input signal, determining an output duty cycle depending on the received input signal, determining an output frequency depending on the determined output duty cycle, generating a pulse width modulated output signal with the determined output duty cycle and the determined output frequency, and driving the brushed direct current electric motor via the generated pulse width modulated output signal. The input signal may indicate at least one of (i) a requested rotational speed of the brushed direct current electric motor and (ii) a requested output motor voltage to drive the brushed direct current electric motor.
