Intake module having integrated ECU

摘要

An intake module has an electronic control unit (ECU) housing portion that houses an ECU. The ECU housing portion is provided in a manner that a lateral direction of the ECU housing portion is approximately coincident with a direction of an intake air passage that is located upstream from the ECU housing portion. Intake air is blown to an air blown area that is located on one side of the ECU housing portion. Heat-producing components and low heat-resistant components are mounted in the air blown area and in an area away from the air blown area, respectively. A plurality of heat-radiating fins is arranged in the air blown area along with a stream of the intake air.
