Abstract
An electronic control apparatus for use in an automobile has a base of a good thermal conductivity having one side disposed in contact with engine cooling water. Semiconductor devices are disposed on the other side of the base so that the semiconductor devices are maintained at the temperature of the engine cooling water, whereby the influence of high ambient air temperature to the semiconductor devices is reduced.
