Abstract:
A device for cooling (a) a planar inductance coil located on a plate-shaped support (10) having a plurality of conducting layers, wherein at least one conducting layer of the support represents the planar inductance coil, and (b) a core element (12, 16) designed to guide magnetic flux, characterized in that said core element includes a first side and a second planar outside surface; on said first side, which is towards a surface of the support (10), the core element is connected to said support by means of a conducting adhesive (44), and said core element is glued on said second planar outside surface over substantially its entire second planar outside surface area to a cooling element (22) having a planar contact surface, thereby providing a thermal connection between said planar inductance coil, said coil and said cooling element, wherein said cooling element serves as a heat bridge for cooling both said core element and said planar inductance coil and for fixing the multi-layer structure assembly.
