Abstract

An electric machine including a housing defining a longitudinal axis. A first plurality of fins coupled with an outer surface of the housing, wherein the first plurality of fins is positioned parallel with the longitudinal axis. A second plurality of fins coupled with the outer surface positioned transverse to the longitudinal axis, wherein at least a portion of the second plurality of fins is located axially adjacent to the first plurality of fins. A third plurality of fins coupled with the outer surface, wherein at least a portion of the third plurality of fins is located axially adjacent to the second plurality of fins and beside the first plurality of fins, wherein the third plurality of fins are positioned transverse to the longitudinal axis. A fourth plurality of fins coupled with the outer surface, wherein at least a portion of the fourth plurality of fins is located axially adjacent to the third plurality of fins and beside the second plurality of fins, wherein the fourth plurality of fins are positioned parallel to the longitudinal axis. A first fan assembly is located above at least a portion of the first and second pluralities of fins, and a second fan assembly is located above at least a portion of the third and fourth pluralities of fins.
