  • Electrical assembly having cavities for coolant
    Patent number: 10483028
    Abstract: The first wall has a first inbound cavity for receiving a coolant from an inlet port. The first wall has a first outbound cavity for directing the coolant from the inbound cavity to the input of the transition passage. The second wall has a second inbound cavity for receiving a coolant from the output of the transition passage. The second wall has a second outbound cavity for directing the coolant from the inbound cavity to the outlet port. The transition passage comprises a transverse hollow volume for interconnecting the first outbound cavity of the first wall to the second inbound cavity of a second wall. At least one heat-generating component (e.g., inductor) in the interior of the housing generates heat that is dissipated.
