Traction inverter component cooling

A method for cooling components in a traction inverter in a vehicle, comprising:

• isolating a plurality of power transistors pneumatically from a plurality of busbars with a plurality of flow guides, wherein:
• a housing of the traction inverter defines a first axis and an outlet vent;
• the plurality of power transistors are disposed within the housing;
• the plurality of busbars are disposed within the housing;
• and
• the plurality of flow guides are disposed within the housing;
• and
• directing an airflow with the plurality of flow guides across the plurality of busbars in a direction parallel to the first axis and out of the housing through the outlet vent.

A vehicle comprising:

• a battery pack operational to present a direct current;
• a traction motor operational to generate a torque in response to an alternating current;
• and
• a traction inverter electrically coupled between the battery pack and the traction motor and operational to convert the direct current into the alternating current, wherein the traction inverter includes:
• a housing that defines a first axis, an inlet vent, and an outlet vent;
• a plurality of power transistors disposed within the housing;
• a plurality of busbars disposed within the housing;
• and
• a plurality of flow guides disposed within the housing, wherein the plurality of flow guides:
• isolate the plurality of power transistors pneumatically from the plurality of busbars;
• and
• direct an airflow into the housing through the inlet vent, across the plurality of busbars in a direction parallel to the first axis and out of the housing through the outlet vent.
