Abstract
A power conversion device includes a first cooler configured to cool a power module, a second cooler configured to cool at least one electronic component, and a housing configured to house the first cooler and the second cooler. The power conversion device also includes a connecting coolant passage formed in an inner wall of the housing such that the connecting coolant passage connects the first cooler to the second cooler. The power conversion device can have the connecting coolant passage formed in the housing, without enlarging a size of the housing. The strength of a side wall of the housing is enhanced because the connecting coolant passage is formed in the inner wall of the housing.
