Cooling pack assembly

A cooling pack assembly for use in a battery-electric vehicle, the cooling pack assembly comprising:

• a cooling fan module including,
• a shroud including a main wall and a plurality of sidewalls extending therefrom, wherein the main wall defines an aperture, and
• a fan disposed in the aperture and configured to rotate about a rotational axis;
• a first heat exchanger having a first cross-sectional area;
• and
• a second heat exchanger disposed between the main wall and the first heat exchanger and having a second cross-sectional area, greater than the first cross-sectional area, wherein the first heat exchanger is spaced apart from a first sidewall of the plurality of sidewalls by a first distance and a second sidewall of the plurality of sidewalls by a second distance to improve acoustic performance, wherein the first distance is substantially equal to the second distance.

A cooling pack assembly comprising:

• a fan assembly including a shroud having a main wall and a plurality of sidewalls extending therefrom, the main wall defining an aperture provided with an inner periphery, the fan assembly further including a fan disposed in the aperture and configured to rotate about a rotational axis, the fan having a plurality of blades and a band interconnecting distal ends of the blades, wherein the band has an axially extending portion, a vertical portion, and a curved portion extending therebetween, wherein the vertical portion is axially spaced apart from the main wall and the curved portion is curved around the inner periphery of the aperture;
• a first heat exchanger disposed on at least one the plurality of sidewalls and having, a first cross-sectional area substantially parallel to the plane;
• and
• a second heat exchanger disposed on at least one the plurality of sidewalls and having a second cross-sectional area that is substantially parallel to the plane and is smaller than the first cross-sectional area, wherein the first heat exchanger is disposed between the fan and the second heat exchanger.
