Abstract
Power conversion sub-blocks are combined to be configured as a power conversion block. The power conversion sub-blocks include power conversion modules including cooler base sections on which semiconductor elements are mounted and cooler fin sections provided on the rear surface side of semiconductor element mounting surfaces in the cooler base sections and cooler attachment members to which cooler fin sections are attached back to back, the cooler attachment members being configured to be capable of separating an opened section where the cooler fin sections are present and external air circulates and a closed section where the semiconductor elements are present and circulating cooling air to the cooler fin sections.
