Abstract
A traction inverter system includes a capacitor module, a power module, a cold plate between and in contact with the modules, and an end plate defining an inlet and outlet. The modules and plates define a bore spanning the modules and plates, and a passageway in fluid communication with the inlet and outlet. The traction inverter system also includes a mechanical fastener occupying the bore, spanning the modules and plates, and clamping the modules and plates together.
Claims16
A traction inverter system comprising:
- a capacitor module;
- a power module;
- a cold plate between and in contact with the modules;
- a power inductor adjacent to at least one of the modules;
- an end plate defining an inlet and outlet, wherein the modules and plates define (i) a bore spanning the modules and plates and (ii) a passageway in fluid communication with the inlet and outlet;
- and
- a mechanical fastener occupying the bore, spanning the modules and plates, and clamping the modules and plates together.
An automotive power system comprising:
- a capacitor module, a power module, a power inductor, an end plate defining and inlet and outlet, and a pair of cold plates stacked and mechanically fastened together such that the cold plates are separated by the capacitor module, power module, or power inductor to form a traction inverter arrangement, wherein the (i) end plate, (ii) cold plates, and (iii) capacitor module, power module, or power inductor collectively define a passageway in fluid communication with the inlet and outlet, wherein the power inductor is between the capacitor module and power module.
A traction inverter system comprising:
- a capacitor module, a power module, an end plate defining an inlet, and a cold plate stacked to form a single unit, wherein the capacitor module, power module, end plate, and cold plate define a passageway in fluid communication with the inlet;
- a mechanical fastener passing through each of the capacitor module, power module, end plate, and cold plate, and configured to clamp the single unit together;
- an
- a power inductor stacked with the single unit.
