Vehicles and electronic assemblies having cooling assemblies with converging and diverging channels

An electronic assembly comprising:

• a plate comprising an array of internal fins, a first surface, a second surface, and a plurality of openings, wherein the array of internal fins defines an array of internal channels;
• a plurality of angled fins extending from the first surface of the plate, wherein the plurality of angled fins define a plurality of channels comprising alternating converging channels and diverging channels, wherein the array of internal channels is fluidly coupled to the plurality of channels defined by the plurality of angled fins;
• and
• one or more electronic devices coupled to the second surface of the plate.
