Document Type and Number:
Japanese Patent JP2013135009
Kind Code:
A
Abstract:
To further improve the heat radiation efficiency in a housing for an on-vehicle electronic control device controlling an engine and a transmission.
A surface of a lid 4a of a housing 4 for an electronic control device 1, formed by aluminum or aluminum alloy etc., has a heat radiation facilitating region where multiple fins are formed.
