Electronic control unit
First Claim
1. An electronic control unit comprising:
- a substrate having a mount face and an opposite mount face;
an electronic component located on a side of the mount face, wherein the electronic component generates heat; and
an enclosure housing the substrate therein,wherein;
a solid, thermally conductive member is placed between the opposite mount face and the enclosure so as to be in contact with a side of the opposite mount face and a side of the enclosure;
a flexible, thermally conductive material is placed between the thermally conductive member and the enclosure to be in contact with a side of the thermally conductive member and the side of the enclosure;
the enclosure includes a case and a cover, which are integrated for housing the substrate; and
the thermally conductive member is soldered to the opposite mount face.

Abstract
An electronic control device having a high heat dissipating ability includes a printed board secured to an enclosure and interposed between a case and a cover with screws passing through the printed board. Thermally conductive thin film layers made of copper foil are formed in parallel on a mount face and an opposite mount face of the printed board and inside the printed board so as to be thermally separated from each other. A protrusion is provided on the cover and protrudes beyond a bottom part of the cover toward the position where an electronic component is mounted. A flexible, semi-solid thermally conductive material is placed between an end face of the protrusion and the opposite mount face of the printed board corresponding to the position where the electronic component is mounted to be in contact with the end face and the opposite mount face.
