An electrically-actuated turbocharger assembly including an electronics assembly, comprising:
- a printed circuit board (PCB), having a first side and a second side, included in a PCB housing coupled to a turbocharger housing;
- a plurality of electrical components mounted on the first side of the PCB;
- a heat sink, configured to receive cooling fluid from a source within a vehicle, positioned between the turbocharger housing and the PCB housing and adjacent to-the second side of the PCB;
- and
- a cooling fluid conduit, configured to communicate the cooling fluid from a fluid inlet to a fluid outlet, wherein the cooling fluid conduit is positioned adjacent to the first side of the PCB and directly contacts an outer surface of the electrical components.
An electrically-actuated turbocharger assembly including an electronics assembly, comprising:
- a printed circuit board (PCB), having a first side and a second side, included in a PCB housing coupled to a turbocharger housing;
- a plurality of electrical components mounted on the first side of the PCB;
- a heat sink, configured to receive cooling fluid from a source within a vehicle, attached to an outer surface of the PCB housing between the turbocharger housing and the PCB housing, the heat sink including a manifold, a fluid inlet, and a fluid outlet;
- and
- a cooling fluid conduit, configured to communicate the cooling fluid from a conduit inlet in fluid communication with the fluid inlet to a conduit outlet in fluid communication with the fluid outlet, extending within the PCB housing, wherein the cooling fluid conduit is positioned adjacent to the first side of the PCB and directly contacts an outer surface of the electrical components.
