Abstract
A cooler for an electronic device of the present invention is provided with a heatsink and a cross flow blower with an electric motor. The heatsink comprises a base and heat exchanging means made as flat disks, fins or flat plates. The base provides thermal contact with the electronic device and the heat exchanging means. The cross flow blower comprises a drum type impeller with an axis of rotation substantially normal to the base. The flat disks substantially perpendicular to the axis of rotation and located inside of the drum type impeller. The fins or flat plates substantially perpendicular to the axis of rotation and located outside of said drum type impeller. The heatsink further comprises heat-spreading means that provide thermal contact between the base and the flat disks and flat plates. The heat-spreading means may be heat-pipes.
