ABS valve body heat sink for control module electronics

A control valve a hydraulic control system including;

• a control valve body having an exterior surface;
• a control circuit substrate disposed adjacent to said exterior surface of said control valve body, said substrate carrying electronic components adapted to control a motor, said substrate forming a thermal interface with said exterior surface of said valve body such that said valve body functions as a heat sink for said electronic components;
• a layer of a thermally conductive material disposed between said circuit substrate and said control valve body;
• a motor having a mounting flange mounted upon said valve body, said motor mounting flange having a recess formed therein which receives said substrate, said motor mounting flange cooperating with said substrate to urge said substrate and said layer of thermally conductive material against said valve body surface;
• and
• a lead frame molded into said motor mounting flange, said lead frame electrically coupled to said electronic components mounted upon said substrate.
