Claim of US Patent No. 10,798,854

1. A power module assembly comprising:power modules each having
a power card including a substrate, signal pins, and power terminals, and
a casing over molded on and in direct contact with a major face of the power card, the casing having (i) a passageway extending between opposite ends of the power module and (ii) a continuous uninterrupted thermal path from the major face of the power card to fluid in the passageway in direct contact with a major face of the passageway, the major face of the power card being parallel with the major face of the passageway, and the continuous uninterrupted thermal path being directly between the major face of the power card and the major face of the passageway,
wherein the major face of the power card is one of a pair of largest faces of the power card, wherein the major face of the passageway is one of a pair of largest faces of the passageway, and wherein ends of the power modules are arranged end-to-end to define a continuous pathway via the passageway of each of the power modules for the fluid to flow therethrough in a direction normal to the ends.
