Abstract: An air coolable electric machine includes a heat dissipation plate with a central opening and an outer periphery. A first side of the heat dissipation plate is arranged for thermal communication with the stator. The heat dissipation plate includes a plurality of circumferentially distributed Y-shaped or ψ-shaped cooling fins extending from a second side opposite the first side. Each cooling fin includes a radially extending leg portion and a V-shaped or ψ-shaped deflector portion that faces the outer periphery to deflect a first portion of airflow outwardly. And the radially extending leg portion of each cooling fin is arranged to direct a portion of airflow inwardly toward the central opening.
