Abstract
An integrated crossflow cooler for electronic components comprises a heatsink with at least two openings, a crossflow blower and an electric drive with a stator and a magnetized rotor. The heatsink comprises a base and heat exchanging means; the base provides thermal contact with the electronic component and the heat exchanging means. The crossflow blower hydraulically connected to one of the openings and comprises a casing rigidly built-in to the heatsink and a drum type impeller comprises magnetic means and serves as a magnetized rotor of the electric drive. The stator made as printed circuit board and rigidly built-in to the casing. The integrated crossflow cooler comprises two types of electric drives—when the magnetic means magnetized in the direction parallel to the axis of rotation and when the magnetic means magnetized in the direction perpendicular to the axis of rotation.
