| 摘要 |
The invention relates to an apparatus (1) comprising: a first heat transfer element (2) comprising a base plate (3), with a first surface (4) for receiving an electric component and channels (5) for transferring a heat load received via said first surface (4) into a fluid in said channels (5), at least some of the channels (5) protrude from a second surface (12) of the base plate (3), 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 (11) is arranged at a second surface (12) of the base plate (3) between at least two of the channels (5), said phase change material (11) absorbing heat by changing phase at a phase change temperature during operation of said electric component. |
