摘要:
The present invention relates to a choke (1) of an electrical device, comprising at least one conductor (2, 3) wound into a coil having separate turns of the conductor wound on top of one another, and a cooling element (4) for cooling the choke. In order to achieve efficient cooling without electrical properties of the choke being impaired, the cooling element (4) is arranged against the coil to cool the conductor (2, 3), wound into a coil, of the choke by means of a medium flowing in a direction parallel to the conductor (2, 3) through a cooling channel provided in the cooling element.

A cooled base plate is provided for electric components. A first side of the cooled base plate is provided for attaching exothermal electric components thereto. On a second side of the base plate, opposite to the first side, there is embedded a cooling channel system having a cooling fluid inlet at a first end of the base plate and a cooling fluid outlet at a second end of the base plate. In order to minimize differences in temperature between the electric components, the thickness of the base plate increases in the direction from the inlet of the cooling channel system towards the outlet of the cooling channel system, e.g., in the flow direction of the cooling fluid, for at least a portion of the length of the base plate.

This disclosure relates to a cooling structure for an electronic device including an inlet for conveying a flow in a first flow direction towards a first component and an outlet for conveying the flow further. To deter dirt particles from proceeding to electronic components, the cooling structure can include a second flow channel, which starts from a port oriented transversely to the first flow direction or away therefrom and receives part of the flow from the inlet, and which conveys the part of the flow to an electronic component located in the second flow channel.
