Abstract
An electronics assembly used in a vehicle included a printed circuit board (PCB) having a first side and a second side; a plurality of electrical components mounted on the first side of the PCB; a heat sink, configured to receive cooling fluid from a source, positioned 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.
Claims6
An electronics assembly used in an electrically-actuated turbocharger assembly, comprising:
- a first printed circuit board (PCB) having a first side and a second side;
- a second PCB having a first side and a second side;
- a PCB housing enclosed around the first PCB and the second PCB;
- a plurality of electrical components mounted on the first side of the first PCB;
- a plurality of electrical components mounted on the first side of the second PCB;
- a heat sink, configured to receive cooling fluid from a source within a vehicle, attached to an outer surface of the PCB housing;
- and
- a cooling fluid conduit configured to communicate the cooling fluid from a fluid inlet to a fluid outlet and extending within the PCB housing and in between the first PCB and the second PCB, wherein the cooling fluid conduit directly contacts an outer surface of the electrical components mounted on the first PCB or the second PCB.
