  • Patent number: 8325479
    Abstract: The present invention relates generally to tuning the flow of cooling air across converter and inverter heat sinks in a motor drive system. More specifically, present techniques relate to motor drive duct systems having parallel cooling air duct channels dedicated to providing cooling air for a converter heat sink and an inverter heat sink, respectively. In particular, a first duct channel through an inverter duct and a converter duct is dedicated to providing cooling air to the converter heat sink without cooling the inverter heat sink, whereas a second duct channel through the inverter duct and the converter duct is dedicated to providing cooling air to the inverter heat sink without cooling the converter heat sink.

  • Patent number: 7952857
    Abstract: An arc-resistant enclosure for electrical switchgear which includes solid front and back walls, a pair of solid side walls joined to the front and back walls, a ventilated roof joined to the side walls and the front and back walls, and a ventilated base joined to the side walls and the front and back walls. Internal partitions divide the space enclosed by the front, back, side, top and bottom walls into multiple compartments for housing different types of components. The ventilated base forms air-intake ports for admitting ambient air into a plurality of the compartments, and the ventilated roof forms air-exhaust ports for allowing air to be exhausted from the compartments. As air inside the enclosure is heated by the switchgear, the hot air rises through the switchgear compartments and is exhausted through the top air-exhaust ports, and replacement ambient air is drawn into the bottoms of the compartments through the air-intake ports.
