Apparatus

Abstract

The disclosure relates to an apparatus including a first heat transfer element having a base plate, with a first surface for receiving an electric component and channels for transferring a heat load received via the first surface into a fluid in the channels, at least some of the channels protrude from a second surface of the base plate, and a second heat transfer element for receiving fluid from the first heat transfer element and passing a heat load from said fluid to surroundings. In order to obtain an efficient cooling, a phase change material is arranged at a second surface of the base plate between at least two of the channels, the phase change material absorbing heat by changing phase at a phase change temperature during operation of the electric component.

Dependencies are inferred from the claim text.
