A cooling arrangement for cooling a heat generating electrical component is disclosed, which arrangement comprises a heat spreading element (2) having a mounting surface (3) adapted to be thermally connected to the heat generating electrical component (1), and a heat rejection surface (4). The arrangement further comprises an enclosure (5) arranged to cover the heat rejection surface (4) and form an essentially closed compartment; an opening (13) leading into the compartment; an annular member (11) coaxially aligned with the opening; and an actuator connected to the annular member (11), and arranged to move the annular member (11) reciprocating away from/toward the opening (13). The annular member (11) hence generates a jet directed through the opening (13) toward the outside of the enclosure (5). |
