Claim of US Patent No. 10,462,936

1. An electronic control unit comprising:a plurality of heating elements;
a substrate that includes a heating region on which the plurality of heating elements are collectively mounted;
a heat sink that is provided to be opposed to one surface of the substrate and includes a radiating part, which is disposed in correspondence to the heating region of the substrate and receives heat generated by the plurality of heating elements;
a housing that is provided to be opposed to the other surface of the substrate, wherein the heat sink includes a fixation part, which is disposed separately from the radiating part and to which an outer edge part of the housing is fixed; and
a plurality of electronic components that are mounted on the other surface of the substrate, the one surface and the other surface being opposite sides of the substrate, wherein
the plurality of heating elements are mounted on the one surface of the substrate and located between the substrate and the heat sink in a direction perpendicular to the substrate;
the radiating part receives heat from surfaces of the plurality of heating elements opposed to the radiating part;
the electronic control unit further comprises a thermally-conductive insulating component between the plurality of heating elements and the radiating part; and
the thermally-conductive insulating component is in direct physical contact with the radiating part and the plurality of heating elements.
