Cooling module for parallel type power module of inverter

A cooling module apparatus for parallel type power modules of an inverter, the cooling module apparatus comprising:

• the parallel type power modules mounted in three or more columns and three or more rows, wherein three parallel type power modules of the parallel type power modules are mounted to correspond to U, V, and W phases of the inverter in the three or more rows in each of the three or more columns;
• a first cooling water passage having a passage through which cooling water flows and contacting with an upper surface and a lower surface of a power module mounted at a first row of the three or more rows among the parallel type power modules;
• and
• a second cooling water passage having a passage through which the cooling water flows and contacting an upper surface and a lower surface of a power module mounted at a third row of the three or more rows among the parallel type power modules.
