MEDIUM VOLTAGE HYBRID AIR/LIQUID COOLED ADJUSTABLE FREQUENCY DRIVE

摘要

An adjustable frequency drive (10) including a number of power modules (14) and a heat management system (16) is provided. Each of the number of power modules (14) includes a number of inverters (30). Each inverter (30) includes a number of power poles (32). The heat management system (16) includes a housing assembly (120, a first heat management assembly (42), and a second heat management assembly (44). The housing assembly (12) defines a power module enclosure (26A) and a liquid cooling assembly enclosure (26B). The first heat management assembly (42) is substantially disposed in the power module enclosure (26A). The second heat management assembly (44) is not substantially disposed in the power module enclosure (26A).
