US Patent 11670443 Liquid cooled inductor via nozzle spray

A vehicle, a vehicle power electronics assembly, and a method of packaging and cooling an inductor assembly are provided. The vehicle has a vehicle electrical system with a variable voltage converter (VVC) and an inductor assembly. The inductor assembly has a core and a winding. A bobbin is connected to and surrounds an outer perimeter of the inductor assembly. The bobbin defines an inlet, an internal fluid passage, and a series of nozzles. The nozzles in the series of nozzles are spaced apart from one another about the bobbin and are positioned to spray fluid directly onto the winding. A fluid system is connected to the inlet to provide pressurized fluid to the inlet.
