Abstract:

The present invention relates generally to efficiently cooling converter and inverter components of a drive system in accordance with present embodiments. More specifically, present techniques relate to a motor drive duct system that facilitates efficient cooling and access to motor drive components. The motor drive duct system includes duct channel paths that are parallel and adjacent to one another. These channels are formed by various duct segments coupled together or integrated to form the duct system. In particular, the duct system includes a converter section that houses a converter heat sink, an inverter section that houses an inverter heat sink, an exhaust section, and an air inlet section. The air inlet section may include a blower for blowing cooling air through the duct channel paths of the converter and inverter sections. The converter section and the inverter section are configured to be attached and detached from each other at end sections that are angled to receive one another. Further, the inverter section, converter section, and air inlet section are configured to roll into and out of a cabinet, which facilitates access to field wiring.
