Abstract
A power module for a motor traction inverter system of a vehicle includes a body portion configured to be inserted into a cooling device and having circuitry established thereat that generates heat during operation of the power module. The body portion has a surface area that is disposed in the cooling device and provides 360 degree direct cooling of the power module around the body portion for cooling the circuitry during operation of the power module. The power module may be transfer molded into a shape with a head terminal for sealing at the cooling device, and electrical connections of the power module share only one side surface or end of the power module, with all other sides and surfaces of the power module being disposed in the cooling device and used for cooling. The power module may not include thermal grease layers and may or may not be insulated.
