Document Type and Number:
Japanese Patent JPS6487822
Kind Code:
A
Abstract:
PURPOSE:To make it possible to keep an electronic control device at a constant temperature, by forming a cooling water passage on one side surface of a substrate made of a material having a preferable heat transmitting performance. CONSTITUTION:On one side surface of a substrate 14 made of a material having heat transmitting performance, such as aluminum, there is formed a recess 16 and a sealing plate 17 is secured with a bolt on the position opposed to the recess 16 so as to form a cooling water passage. Meanwhile, on the other side surface of the substrate 14, semi-conductor elements such as a temperature sensor 6, knock sensor 7, input unit 8, output sensor 10, arithmetic unit 9, memory element and the like are secured through a ceramic made substrate 20. On a side surface opposed to the sealing plate 17 of the substrate 14, a surrounding body 23 is secured through a seal ring 24.
