Abstract

For cooling electric equipment in an electric automotive vehicle, an exhaust duct carrying exhaust air flowing from an electric compartment located behind and / or beneath a seat extends beneath the seat and exhausts into the passenger cabin. The exhaust duct has at least one air induction opening therein downstream from the electric compartment to draw auxiliary cooling air from the passenger cabin into the duct to join with the exhaust air. As exhaust air from the electric compartment passes through the exhaust duct, auxiliary cooling air is drawn into the exhaust duct through the air induction openings and mixes with the warmer air from the compartment to reduce the temperature of the air mixture exiting the exhaust duct. Air mixing features may be located inside the exhaust duct to improve mixing of the air flow from the electric compartment with the auxiliary cooling air.

Description

technical field [0001] The invention relates to electrically driven motor vehicles having air-cooled electrical components. Background technique [0002] Electrically driven vehicles (e.g., hybrid electric vehicles (HEV), plug-in HEVs, pure electric vehicles, etc.) typically include electrical components (batteries, battery chargers, converters (DC / DC, AC / DC, and / or DC / AC), and / or inverter). Such electrical components (particularly high voltage components) may generate relatively large amounts of waste heat and thus may require some degree of active cooling. Such cooling may be achieved by providing a relatively steady flow of air into the electrical compartment from the vehicle passenger compartment, cargo compartment, and / or exterior of the vehicle. [0003] In one common vehicle layout, an electrical compartment containing electrical components is located directly behind and / or below one or more passenger seating positions. A fan pushes or draws cooling air through the...
