AI Technical Summary

Technical Problem

The existing motor drive devices suffer from reduced cooling efficiency due to protrusions on the second cover member, which hinder effective heat dissipation from the heating element to the circulating oil.

Method used

A cooling module configuration with a circuit board mounted on a module housing that includes a cooling channel and a heat conductive member, where the substrate is housed in a space enclosed by the flow path housing, and an insert-molded busbar provides power to the substrate, allowing for heat dissipation through a coolant flowing through the cooling channel.

Benefits of technology

This configuration enhances cooling performance by efficiently dissipating heat generated by the driver to the coolant, enabling miniaturization and improved cooling efficiency.

Abstract

A cooling module according to the present invention includes: a substrate on which a driver for energizing an auxiliary machine installed on a vehicle is mounted; and a module housing for holding the substrate. The module housing has a flow-path housing inside of which is formed a cooling flow path through which a cooling liquid circulates. A heat conducting member is provided spanning the substrate and the cooling flow path.
