1. A heat dissipation system, comprising:
an electric motor comprising a stator, the stator comprising a plurality of stator teeth, each stator tooth of the plurality of stator teeth having conductors wrapped there around;
a thermal management system comprising a first heat exchanger and a second heat exchanger, the first heat exchanger being formed into a plurality of microchannels that are thermally exposed to the conductors wrapped around each stator tooth of the plurality of stator teeth;
a heat-transfer fluid disposed in the thermal management system; and
a pump fluidly coupled to the first heat exchanger and the second heat exchanger for circulating the heat-transfer fluid; and
a plurality of channels formed on a surface of the conductors wrapped around a stator tooth of the plurality of stator teeth, wherein a microchannel of the plurality of microchannels is disposed in each channel of the plurality of channels.
