Patent Images
1. A charger assembly comprising:
- a housing having a cavity with an opening;
a cover fastened to the housing to cover the opening;
a heat transfer duct mounted to the cover with an inlet end and an outlet end each extending through the cover;
a plurality of heat sinks mounted to the cover in contact with the heat transfer duct; and
a plurality of circuit board assemblies each mounted to the cover in contact with the plurality of heat sinks;
wherein the heat transfer duct comprises a bent piece of round tubing having an inlet region extending through the cover from the inlet end in a depth direction of the housing, an intermediate region extending transversely through the housing, and an outlet region extending in the depth direction through the cover from the intermediate region to the outlet end; and
wherein each heat sink comprises a generally planar contact portion to contact the circuit board assembly, and a curved portion to extend around the round tubing.
