COOLING SYSTEM OF EXPANDABLE INVERTER AND MECHANICAL ASSEMBLY THEREOF

Disclosed are a cooling system of an expandable inverter and a mechanical assembly thereof. The cooling system comprises an inverter casing (1), a cooling housing (2) arranged within the inverter casing (1), and a cover plate (3). An empty groove (20) is arranged on the top face of the cooling housing (2). The cover plate (3) is mounted on the top face of the cooling housing (2) and seals the empty groove (20). A water way structure (4) is arranged at the bottom face of the cover plate (3). The water way structure (4) extends into the empty groove (20) such that M parallel water grooves (40) are formed within the empty groove (20). The number M of the water grooves (40) is variable and the range thereof is between 3 and N, in which N is an integer larger than 3. The number M of the water grooves (40) can be expanded based on the number of power modules (6) to be cooled so as to meet the demand of different types of electric vehicles, having a high flexibility, convenience and strong versatility.
